e-Business, Omar A. El Sawy
- BPR
- a performance improvement philosophy that aims
to achieve quantum improvements by primarily
rethinking and redesigning the way businesses are
carried out - Business Processes a set of activities that
transform a set of inputs into a set of outputs

8BPR ERPWhat is ERPRelationship with BPR
9Enterprise Resource Planning
- ERP is a software solution, with all the
organisations records managed from one large
database. An integrated IS. - It takes the process view of an organisation to
meet the organisational goals tightly integrating
all functions of an enterprise. - (more about ERP history to come)
10Relationship BPR - ERP
- A BPR study
- brings out deficiencies of the existing system
- attempts to maximize productivity through
- re-structuring and
- re-organising the human resources as well as the
divisions and departments in the organisation - BPR will initially question the value-add of the
particular process - Then it will go on to put some systems and
procedures in place -gt ERP is a key enabler in
any BPR effort
11Relationship BPR ERP (2)
- You can
- do BPR without buying an ERP solution,
- unusual
- buy an ERP solution without doing any BPR
- wasteful investment...
- The question is not whether ERP functions or not
without BPR - Key question whether every company that
implements ERP has to reengineer its processes
12ERP
- ERP doesnt blindy automate- it takes into
account - companys internal issues,
- but also factors in the external imperatives in
terms of competition, time-to-market,...
13ERP (2)
- ERP is the planning of the 4Ms of the enterprise
resources Man, Money, Materials, Machines. - ERP helps in addressing needs like reduced cycle
time, customer focus, sharing information
seamlessly across the enterprise and JIT
management
14ERP- Dynamics of OM
- Scope of the book
- to help and support the development of teams to
implement the Integrated Production and Order
Management (OM) approach - The Four cornerstones for success flexibility,
time, quality and cost - Four main functional activities Marketing,
Purchasing, Production, Finance
15ERP- Dynamics of OM (2)
- A book delivered with a software
- the Operations Trainer
- a dynamic-integrated environment for students
and executives to experiment with IPOM and to
learn the ERP concepts
16Review of a bookERP-Dynamics of Operations
Management, Avraham Shtub
17Operations Management
- Several approaches to Operations Management
- operations research oriented
- case studies oriented
- A new approach proposed by Hammer and Champy the
reengineering of business processes to inflect
changes on organisations
18IPOM approach
- New managerial approaches
- Concurrent Engineering
- an integrated, dynamic approach to new product
development. New product development teams
composed of experts from different functions.
Share the same goals. - Group Technology
- focused cells specialising in a small number of
similar products.
19IPOM approach (2)
- Development of IS
- MRP- Material Requirement Planning
- not good enough on its own...
- Integration of modern DBMS, DSS and MIS
- -gt the new generation of ERP systems was borned
- An essential process- The order fulfilment
- -gt Integrated Production and Order Management
20IPOM approach (3)
- Process-based
- Process order fulfilment- from the reception of
a customer order to the supply of the right goods
on time, the required quantities and at a
competitive cost - ERP supported
- 3 types of IS support Order fulfilment process
- Transaction Processing System (any transaction
can be ordered/analysed via the software) - MIS (a unique database)
- DSS (decisions consequences can be analysed, ...)
21IPOM (4)
- An Integrated IS
- finance, marketing, production, purchasing
- that supports order fulfilment process
- Transaction processing systems / MIS / DSS
- A single DB
- A model base (for well-structured/routine
processes, for non-structured/-routine problems,
or for process control)
22Marketing Considerations
23Production and order policies
- Process triggered by customer orders
- Written form, long term contract, order issued by
marketing based on a demand forecast - Orders entered into Master Production Schedule
- Competition in order fulfillment process
- time, cost, flexibility, and quality
24Production and order policies (2)
- Inventories of finished goods are used to buffer
against uncertainty (in forecasting) - Several alternatives to initiate purchasing
orders and production orders - based on firm customer orders
- based on demand forecasts (raw mat. inv.)
- based on firm customer orders current inv.
level of raw materials and parts
25Production and order policies (3)
- Importance of lead-time
- time from order to delivery
- Supermarket approach
- if acceptable lead-time gt actual lead-time
no inventory - reduce setup times and batch sizes
- if acceptable lead-time lt actual lead-time
keep enough inventory to cover for the
difference
26Three types of order policies
- Make to stock
- new production triggered by forecasts
- Minimizes the promised lead-time at the cost of
carrying inventories - Make to order
- No stocks carried
- Only customer order triggers production
- Assemble to order
- Raw materials and parts stocked but final
assembly triggered by customer order
27Master Production Schedule (MPS)
- Statement of planned future, gross requirements
of end products - MPS triggered by the market demand
- combination of orders and forecasts
- If order fulfillment process not well integrated
conflict highly likely - marketing, production/purchasing
- different measures of performance
28Master Production Schedule
- To avoid conflict
- common set of goals
- Appropriate performance measures
- Management of MPS
- introduction of new requirements
- updating existing requirements
- monitoring and control of actual performance
compared to goals
29Lead-time and time based competition
- Importance of time in order fulfillment
- shorter lead-time
- competitiveness and ability to get new business
- delivery on right time
- promised vs. actual lead-time
- Lead-time
- data processing, decision making, production
- Each operation affects lead-time
- should be studied and optimized
30Optimization of operations
- Elimination of unnecessary operations
- Minimization of the duration of necessary
operations - Minimization of delays before, after, and during
the operations - batch production --gt reduce setup times
- get rid of bottlenecks (DBR)
- information sequentially - hierarchy levels
- control points --gt data sharing
31Quality and its management - quality based
competition
- Success dependent on customer satisfaction
- Eight dimensions in quality based competition
- performance, features, reliability,conformance,
durability, serviceability, aesthetics, and
perceived quality - Order fulfillment process
- DDP Due Date Performance
32Cost considerations -cost based competition
- Profit selling - buying price
- Higher profit reduce the cost of products
- Problem of measuring costs of a unit
- direct, indirect costs
- fixed, variable costs
- Solution
- Look at the throughput
33Summary of Chapter 4
34Purchasing and Inventory Management
35The Need for Outsourcing
- Outsourcing purchase some materials, parts, and
services from outside services - increase effective capacity without capital
- enhance the organizations competitive edge
- Points to be carefully evaluated
- Make or buy decision
- supplier management
- inventory management
36OutsourcingMake or Buy Decisions
- Factors to be taken into consideration
- Capacity, Know-how, Cost-Volume, Demand pattern,
Time, Quality, Control and Feasibility - Decision making levels
- Strategic level
- what part of production kept in house
- Operational level
- capacity considerations
37OutsourcingSupplier management
- Importance of order fulfillment process
- purchases constitute 30-50 of sales
- Sub-activities
- specifications of requirements
- selection of suppliers
- contract management
38Specifications of Requirements
- Definition of the required product or service
including functional, physical and technical
specifications - Definition of the order fulfillment process
requirements, including required lead time, size
and number of shipments, shipping arrangements
and frequency of deliveries - Definition of quality system the supplier should
employ and quality requirements applied to the
product or service
39Selection of Suppliers
- Different approaches single vs. Multiple
- Supplier evaluation considerations
- Process capability
- Can supplier produce in specific quality level?
- Quality assurance
- Are quality control procedures adequate?
- Financial capability
- the risk associated with doing business with
supplier - Cost structure
- Suppliers costs (mat., labor, OH.) and profits
40Selection of Suppliers
- Value analysis effort
- Ability to perform value analysis (past success)
- Production scheduling
- Abilities of production planning and control
system - Contract performance
- Performance measures to evaluate suppliers
- Can also rely on standard specifications
- e.g. ISO 9000 series
41Contract management
- The ongoing relationship with supplier
- Three categories of relationships
- Inspection
- focusing on product inspection to eliminate
defects - Prevention
- purchaser helps to build quality into the product
and process - Partnership
- long term relationship
- e.g. Joint design, delivery directly to the point
of use - JIT-approach
42Inventory ManagementBenefit and cost
considerations
- Inventory management
- policies, decisions, actions and the monitoring
and control of stock - Stock types
- Raw materials, parts and components, work in
process, finished goods, supplies
43Inventory ManagementBenefit and cost
considerations (2)
- The benefits of using stocks
- Time based competition
- reduce lead time)
- Coping with uncertainty
- buffer inventories)
- De-coupling activities in the order fulfillment
process - Cost based competition
- order in large quantities)
- Technological considerations
- some processes are designed for a batch of a
given size
44Inventory ManagementBenefit and cost
considerations (3)
- Many benefits, but still inventories are
expensive and create waste - search for trade off btw. benefits and costs
- Inventory costs
- capital costs
- operating costs
- risk related costs
- JIT -gt inventory wasteproblems
45Inventory ManagementBenefit and cost
considerations (4)
- ABC or Pareto Analysis
- type A 20 of items, count for 80 of costs
- type B 30 of items, count for 15 of costs
- type C 50 of items, count for 5 of costs
Add here scanned picture from page 70!
46Inventory ManagementModels and their assumptions
- Help when to place order and what quantity to
order - the economic order quantity (EOQ) model
- Problems
- assumes demand constant
- stable inventory costs
- lead time constant
- no interactions between different items
- constant parameters
Add here scanned picture from page 72!
47Inventory ManagementModels and their
assumptions (2)
- (s,S) Model
- whenever the current inventory level drops below
predetermined value (s), and order is placed to
bring the inventory level to the higher
predetermined value (S) - Advantage not based on simplifying assumptions
like EOQ model
48Summary of Chapter 5
49Scheduling
50Job ShopImplementing Priority Rules
- Scheduling is concerned with allocation of
limited resources to tasks over time - the driver Master Production Schedule (MPS)
- Variety of scheduling models have been developed
and implemented - based on assumptions technology, layout,
objectives and constraints of organization,
environment
51Job ShopImplementing Priority Rules (2)
- Machines performing the same function grouped
- Scheduling objectives
- on time completion of each part according to MPS
- the completion of all jobs as early as possible
- minimization of the time that parts spend in the
shop (min. process inventory) - maximization of the utilization of resources by
minimizing their idle time - minimization of costs by using less expensive
materials
52Job ShopImplementing Priority Rules (3)
- When setup time is significant and machine
capacity limited --gt batch processing - Several models exist to provide optimum
- only for very small problems
- based local view of a larger situation
- How to assign priority (simple methods)
- FIFO (First In First Out)
- EDD (Early Due Date)
- Current job (to save setup time)
- SPT (Shortest Processing Time)
53Job ShopImplementing Priority Rules (4)
- How to assign priority (complex methods)
- Critical ratio (CR)
- difference between due date and current date
divided by time required to complete the
remaining work. - Slack Time Remaining (STR)
- difference between the time remaining before the
due date and the time required for processing the
remaining jobs. - Slack Time Remaining per Operation (STR/OP)
- average slack time per remaining operation.
- Smaller values have higher priority (for the 3
methods)
54Job ShopImplementing Priority Rules (5)
- By monitoring the situation on the shop floor and
selecting the right priority rules for the
situation, the management can improve
performances on the delivery schedule - Also scheduling manually is possible when job is
late
55Job ShopImplementing Priority Rules (6)
- The selection of most appropriate priority rule
as well as decision to expedite a job, is based
on the Shop floor control system - current information on the jobs waiting for
processing in front of each machine - Priority rules based on single machine
- starvation --gt monitor continuously inventory
levels in front of each machine - control by input-output analysis
- identify bottlenecks
56Flow ShopScheduling
- In the flow job all product types are processed
in the same order - problems starvation and blocking
- especially when product units are large and
in-process inventory is limited (JIT) - Flexible flow job
- many similar machines operate in parallel
57Flow ShopScheduling (2)
- Johnsons rule
- for simple cases (2 types of machines)
- objective to minimize make span
- Insert here POSSIBLE EXAMPLE!
- Based on simplifying assumptions
- --gt direct implementation of their results may
lead to poor performance of the order fulfillment
process
58The Just In Time (JIT) Approach
- Founder Dr. Ohno of Toyota, Japan
- Profit revenue - costs
- to increase profit
- increase revenue
- reduce costs
- Focus on cost (waste) reduction
59JIT Approach (2)
- Potential forms of waste according to JIT
- Quality related waste
- Inventory related waste
- Waste of space
- Material handling waste
- Distinction between value-added and non
value-added operations - eliminate (if not possible minimize) non
value-added operations, such as material handling
60JIT Approach (3)
- Impacts of JIT in scheduling
- minimize process inventories
- use small batch size (ideal batch size 1)
- promote faster setups
- use of scheduling systems
- limit space available for inventories in process
- preventive maintenance efforts
- quality at the source
- long term, close relationships with suppliers to
ensure quality and delivery when needed
61JIT Approach (4)
- To succeed in the elimination of waste while
keeping the competitive edge in time based
competition, the order fulfillment process in the
JIT system is synchronized and controlled by a
special system - KANBAN cards
- Contains information production order, purchase
order, inventory control device - Integrated (all work centers are connected)
- Dynamic (inventories limited by of Kanbans)
62JIT Approach (5)
- Just in time is a form of synchronous production
- a system in which entire order fulfillment
process is synchronized (i.e. works in harmony)
to achieve its multidimensional goals (time,
cost, flexibility, and quality) - The synchronizing device - the Kanban card
provides tight connection between the work centers
63The Dynamic ShopExpediting and Changing
Priorities
- Demand fluctuates over time, solutions
- manufacturing to stock
- buffer inventories
- freeze MPS (master production schedule)
- stabilize demand over the freeze period
- monitor each job as it moves
- ERP systems analyze data and support decision
making - focus on problematic work centers
- derive the schedule according to bottlenecks
64The Drum, Buffer, Rope (DBR)Approach
- In this scheduling technique the schedule of all
work centers is driven by the schedule of
critical work centers (insufficient capacity) - Three performance measures
- MAX Throughput (T) Sales - Expenses
- MIN Inventory (I)
- MIN Operating expenses (OE)
- avoid production to stock
65The Drum, Buffer, Rope (DBR) Approach (2)
- Focus should be on the constraint as it is the
weakest link in the chain of the order
fulfillment process

66Summary of Chapter 6
67Material Requirement Planning
68Material Requirement Planning (MRP)
- Is an early attempt to develop an integrated MIS
for the order fulfilment process - By combining information on the demand for
products purchased by the customers with
information on the structure of these
products,the required quantities of dependent
demand item do not have to be forecasted-they can
be calculated.Uncertainty associated with
forecasting is reduced - By integrating the inventory management
information into the system the requirements for
dependent demand items as well as those for
independent demand item can be placed against
existing inventories and pipeline inventories so
that only the net required can be ordered
69MRP (2)
- By introducing lead time information for
purchased items and for manufactured items
manufacturing and purchasing orders can be time
phased to ensure delivery exactly when needed
- The original MRP System (MRP I ) combined
- Marketing information in the Master Production
- Technological information about the structure of
each product and its manufacturing process - New capabilities were added to these systems
including - Planning module that reveal capacity shortage
- Shop floor control modules that utilise limited
capacity efficiently - MRP II (Manufacturing resource Planning).Systems
that deal with resource capacities were born
70MRP (3)
- MRP II Systems deal with resource
- recent development in this area produced ERP (
Enterprise Resource Planning) Systems designed to
support the order fulfilment process of an
enterprise operating several factories warehouses
and integrated logistic system a complex known as
the supply chain

72The typical data file (2)
- Many MRP installations did not fulfil the
expectations improve the order fulfilment
process. There are several reasons for the
failure of MRP System - Quality of input data
- Team mutual understanding on how to use MRP
- The early MRP System dedicated files were used to
store the data, as database technology were not
available.
73The typical data file (3)
- The important data files in the early MRP
applications were the following - The Master Production Schedule (MPS)- The MPS is
the anticipated build schedule for selected
(independent demand) items by quantity per
planning period - Marketing information on actual customer orders
and forecasts of future demand. - Manufacturing information on the current load on
the shop floor and the ability to supply
additional customers orders during each period in
the planning horizon
74The typical data file (4)
- Purchasing information on suppliers lead-time
and the availability of purchased parts and
materials in inventory and in the pipelines - Cost information on the cost of manufacturing
each independent demand item. - Master Production Scheduling is an excellent
example for the need to integrate the different
aspects of the order fulfilment process
75The typical data file (5)
- The time frame used for the MPS is important.The
minimum planning time period known as time
buckets specifies the accuracy of the planning
process, a time bucket of one week is typical - The minimum length of the planning horizon should
be equal to the total time required to purchase
raw materials and component parts, to manufacture
and assemble the independent demand item with the
longest lead time, to provide enough time for the
order fufilment process to supply this item when
needed
76The typical data file (6)
- Change management is an important part of the
order fulfilment process - Change in the MPS create changes in the
production and purchasing plans that results in
nerveousness of the system and in low
efficiencies, excess inventories and an unstable
order fulfilment process - The MPSis updated continuously
- When current time is over, the next period
becomes the current one and a new period enters
the planning horizon
77The typical data file (7)
- Key issues to consider are who should mange the
MPS and How - The Bill of Material-The Bill of Material or BOM
is the source of information about the structure
of each independent demand item. Through the BOM
it is possible to coordinate the requirements for
subassemblies, components and raw materials - The Inventory Record-To function properly, the
MRP system compares the gross requirements for
each part number to its current inventory.Only if
the gross requirements exceed the current
inventory an order for that part number should be
issued
78Gross to net and time phasing The MRP logic
- MRP systems are designed to support the material
management function in the order fulfilment
process - The Basic idea is that the same logic can be
used for ordering purchased materials or parts,
manufactured components and assembled products - The MPS is the source of information on gross
requirements for independent demand items - Basic MRP logic makes use of this information as
input and translates it into time phased net
requirements
79Gross to net and time phasing The MRP logic
The Basic MRP record for product A
Week 0 1 2 3 4 5 6 7 8 9

80Gross to net and time phasing The MRP logic
Projected available balance (t1) Projected
available balance Scheduled receipt
(t1) -Gross requirement (t1)
- Based on the calculed projected available balance
a decision to issue work orders or purchase
orders is made - A simple decision rule known as LOT FOR LOT
(LFL)
81Modification of The MRP logic
- MPS is used as the resource of Gross
requirements for independent demand items. - Basic MRP logic is modified to accomodate special
situations. a common modification is in the lot
sizing policy - The Economic Order quantity (EOQ) logic discussed
early, is frequently used to calculate this
minimum size. The same logic applÃes parts when
economy to scale is available - Ex The cost per unit decrease as the order size
increases
82Modification of The MRP logic
- Other modifications in the lot sizing policy are
based on the idea that each order should cover a
minimum period of demand - That is know as the Periodic Order quantity
- Unlike LFL logic both EOQ and POQ generate
inventories - Another modification of the MRP logic is to
buffer against uncertainty
83Modification of The MRP logic
- Two types of buffers
- Buffer stock- in this case the minimum inventory
level target is set. - Buffer lead time-this method is designed to
protect the system from fluctuations in supply
lead-time. It is based on increasing the lead
time of part number by a predetermined amount to
protect the system against uncertainty in the
actual deleivery dates
84Capacity considerations
- MRP logic of gross to Net and Time Phasing
derives the requirements for material from the
MPS - Early applications of MRP logic focused on
material requirements - To coordinate resource availability with resource
requirements, capacity considerations had to be
added to the basic MRP system - One way of doing that is known as Rough cut
Capacity Planning (RCCP) - Another approach is known as Capacity Requirement
Planning (CRP)
85Capacity considerations Rough cut Capacity
Planning (RCCP)
- Rough cut Capacity Planning (RCCP) is performed
at the MPS level. Its major inputs are the MPS
and Information about the processing time per
unit product on each machine or work center - The logic used for Rough cut Capacity Planning
varies in its complexity and in the accuracy of
the capacity requirements forecasts generated
86Capacity considerations Rough cut Capacity
Planning (RCCP)
- Rough cut Capacity Planning is an important tool
for the management of the MPS - Rough cut Capacity Planning is also the basis for
setting priorities in monitoring and controlling
the shop floor - This is logic is the basis of the work of
Goldratt and Fox (1986) which an effort to
identify the few resources that are short of
capacity and to schedule the whole operation in
such a way that these resources will be used
efficiently and effectively
87Capacity considerations Rough cut Capacity
Planning (RCCP)
- Goldratts logic is translated into the following
step - Identity the systems constraints ( the
bottlenecks)-this step can be based on rough
estimates of the load on each resource compared
to its available capacity - Develop a detailed schedule for the
bottlenecks-using simple techniques such as Gantt
Chart - Derive the schedule for all non-bottleneck
resources from the schedule developed for the
bottlenecks. Since the non-constrained resources
have excess capacity the assumption is that it is
possible to schedule these resources to support
the schedule of the bottlenecks - Repeat the process-Since bottlenecks may change
over time as the product mix changes or due to
changes in resources capacity, it is necessary to
identify the systems constraints repetitively
every and to watch the actual utilisation of the
bottleneck to avoid idle time
88Capacity considerations Rough cut Capacity
Planning (RCCP)
- The use of the MPS as a basis for rough cut
capacity planning may lead to substantial errors
in estimating the resource requirements - To overcome these difficulties a more detailed
approach for capacity planning is used
89Capacity considerations Capacity Requirement
Planning (CRP)
- Capacity Requirement Planning (CRP) is based on
an effort to treat the requirements for resources
by logic similar to the logic used for material
planning - Logic based on the output of the MRP-work orders
generated by the gross to Net and the Time
Phasing logic - Based on the orders released by MRP logic, the
required periodical capacity of each resource is
calculated - The MRP logic that generates work orders takes
existing in process inventories into account in
its gross to net analysis the capacity
requirements are more accurate
90Capacity considerations CRP Vs. RCCP
- Both CRP and RCCP are tools for testing the
feasibility of the plans developed by the MIS - The RCCP test the feasibility of the MPS while
the CRP tests the feasibility of the MRP plans - Both tools are based on estimates of available
capacity and forecasts of expected loads and
therefore do not provide perfect accuracy - A module called shop Floor Control is added to
support the order fulfilment team in its resource
management tasks
91Capacity considerationsShop Floor Control (SFC)
- The module implement logic known as Input-Output
analysis - The logic is based on monitoring the actual
queue of work orders in front of each work centre - The name Input Output analysis comes from the
analogy between the queue in front of a work
centre and reservoir - The complete MRP II system consist of the basic
MRP I module plus the RCCP,CRP and SFC modules
(see Schema next)

93Managing the Integrated Order Fulfilment Process
Using ERPSetting goals, Establishing
performance, Measures developing policies and
Taking actions
94The role of management in the integrated order
fulfilment process
- Organization structures establish clear
relationships and communication lines between
managers and subordinates, within these
structures the lines of authority and
responsibility are easy to define and maintain - The traditional functional organizational
structure may not provide adequate support for
the management of the order fulfilment process
due t the following problems
95The role of management in the integrated order
fulfilment process (1)
- Problems
- Each functional organizational unit tends to
focus on its local goals and objectives - In a functional organization the order fulfilment
does not have a clear owner responsible for its
performances from start-getting a customer order,
to finish-supplying the order efficiency and on
time
96The role of management in the integrated order
fulfilment process (2)
- Concurrent Engineering-is based on a team of
experts in the areas of product development,
manufacturing and logistics support - Application of this new approach improved the
communication between the participants in the
development process and resulted in a shorted
development cycle - Team building is a challenging managerial task
and it is a process of organizing, staffing,
motivating and leading people
97The role of management in the integrated order
fulfilment process (3)
- Responsibility of the order fulfilment team to
plan, direct and control the activities of the
resources used to perform the order fulfilment
process - Information acquired by marketing, purchasing and
operations management represents the common
Knowledge that should be shared by all the
members of the order fulfilment team - This common knowledge provides the ability to
communicate, to set common goals and to develop
an integrated plan that can be controlled and
directed efficiently by the team
98The role of management in the integrated order
fulfilment process (4)
- The common knowledge and the understanding that
the whole team shares the responsibility for the
entire order fulfilment process is the
cornerstone of a successful ERP implementation - Planning starts with the definition of the goals
for the whole order fulfilment process and the
agreement on the frame to reach the goals
99The role of management in the integrated order
fulfilment process (5)
- A combination of long term and short-term gaols
is needed - A short term goal may be to supply a customers
order ahead of its promised due date when a
preferred customers order ahead of its
promised due date - a long term goal is to become a leader in the
market and to capture a market share of fifty
percent or more within two years
100The role of management in the integrated order
fulfilment process (6)
- The plan provides each team member with exact
information on what he is supposed to do and when - The plan integrates and coordinates the efforts
of individuals involved in the process and
facilitate teamwork.It serves like - A note (in an orchestra)
- A Compass
- Deviations from the original plan are likely due
to - Uncertainty
- Late delivery
101- Special action as opposed to long lasting
policies are needed when deviations are detected - The ERP concept of a single information system
that supports all the processes in the
organisation by providing an integrated data base
and a comprehensive model base is therefore
essential for successful implementation - Learning how to use the ERP, how to work in a
team, and how to lead in a dynamic, integrate
environment is equally important
102The Hierarchy of Goals
Alice in Wonderland
Should with turn right or left?
He does not matter!
In that case you can go either way
Where do you want to go?
Alice
103- This global goal is translated into several lower
level goals such as - Time related Goal
- Deliver in a short lead-time
- Deliver on time to the customers
- Cost related goals
- Deliver at the minimum cost possible
- Minimize the operating cost of the process
- Minimize inventories to minimize the
inventory-related costs
104Developing a plan-The road map to the goal
- A plan that coordinates the efforts of the team
members - Coordination is easier in a repetitive
environment where the same hierarchy of goals is
valid over a long period of time and the same
plan may be applied rapidly to reach these goals - As long as the goal does not change, the MRP
logic is implemented correctly and uncertainty
does not intervene, the automatic planning
process should yield the desired results
105Establishing Control-Identifying Problem
- To reduce the effect of uncertainty, management
tries to establish estems that identify problems
in implementing its plans as early as possible - Control systems are common in many engineering
and organizational applications - ExThe control of the rooms temperature
- The control of the order fulfilment process is
based on the same principles, but more human
decision making is required when the process is
not repetitive
106- First approach, Monitoring the value of the
performance measures is one way to go - Ex If due date performance is an important
measure it is preferable to detect problems on
the shop floor that might cause delay in a
customer order or to detect late deliveries from
suppliers and fix these problems before due date
performance level is affected - The Three aspects of the order fulfilment should
be monitored continuously - The interface with customers
- The interface with suppliers
- The performance of the shop floor
- The second approach, fits generative MRP systems
where translations are collected and processed as
a batch to update the mater files of the MRP
systems
107- A combination of continuous and periodic control
is essential for a successful, flexible order
fulfilment process - the design of the control system is an important
part of any ERP implementation
108Taking Action-Solving Problem
- To analyse the source of problems and decide
whether there is a need to change the current
policy in order to avoid the occurrence of
similar problems in the future - Problem solving is tricky due to the integrate,
dynamic nature of the process and the uncertain
environment - System behaviours can be difficult to grasp and
even more difficult to predict
109- First step in solving problems is to recognize
that there is a problem and to define it clearly - Next step, is to define it in clear terms. The
performance measures used to evaluate the process
are the basis for problem definition - Then-problem analysis
- The third step-is to generate alternative
solutions to the problem. Two types of solution
are needed - Ad-hoc solution
- Long term solution
- the alternatives expected to yield the best
results are selected and implemented in the
process
110- Problem solving approach can be summarized as
follows - Identify the problem
- Define the problem in term of the process
performance measures - Analyse the problem to find its roots
- Generate alternative long and short range
solutions - Evaluate the solutions with respect to their
effect on the performance measures - Select the best solutions
- Implement the selected solutions
111Policies Control Systems and Actions in the
Operations
- The integrated dynamic management concept is
based on managements ability to - Understand the whole order fulfilment process and
the interactions between its different aspects - Establish goals and performance measures
- Develop adequate policies based on the
understanding of the whole process, its goals,
its performance measures, its different aspects
and the dynamic interactions among these aspects - Design a monitoring system and use its signals to
control the whole process - Develop problem-solving skills as individuals and
as a group - Implement the policies, controls and solutions to
problems
112- The selection of policies
- Marketing policies
- Make-to-stock
- Make-to-order
- Production policies
- Dispatching policy
- Purchasing action
113Teaching and Training Integrated Production and
Order Management
114Individual Learning and Organisational Learning
- The essence of Integrated Production order order
Management is teamwork. A process based
organization is responsible for each process. - In the functional organization people are grouped
according to the function they perform and are
trained to focus on their part of the order
fulfilment process.
115- IPOM is based on an integrated approach to the
order fulfilment process (integration as the
opposite of de coupling). - IPOM environment each member of the team have to
understand the whole process including the role
of every other team member. all team members
participate in the decision making process - The teaching of IPOM at the individual level
starts with the basic concepts of information and
its use
116- Building the team and training it to play
together as a team is very important. Each player
has to understand his role and to excel in it.
Coordination between the players is also an
important part of training a basketball or a
football team - The high degree of dependency among the players
and the dynamic, stochastic environment requires
team building and team learning
117Individual Learning Curve
- if each individual is an expert in his task the
integration of individual expertise by well
planned organizational structure provides the
organization's competitive edge - Individual learning can take many forms including
the learning of verbal knowledge, intellectual
skills,cognitive strategies and attitude - Learning by imitation
- Learning by repetition
118Learning curve model
Direct Production time
Unit Number
30
119- Group learning in its simplest form is an
aggregation of individual learning - Three problems with the extension of individual
learning curve to group learning - First, the learning coefficients of individuals
in a group are not necessary the same - Second, Absenteeism turnover and job rotation
makes the organizational learning curve difficult
to predict ... - Third, problem related to synergy in team
120Teambuilding and the Team Performance Curve
- Katzenbach and smith (1993) relates the types of
group and its performance
Performance impact
High-performing team
In this model five types of groups are defined
Real team
Working group
Potential team
Team effectiveness
Pseudo team
121- The Katzentbach and smith (1993) model explains
how important it is to combine individual
learning with team building in order to succeed
in implementing integrated Production and Order
Management - There are several barriers that a new team must
overcome (Thamhain and Wilemon (1979)) - Unclear objectives
- Differing outlook
- Role conflicts
- Personnel selection
122- Katzenbach and smith (1993) list several hints
that can help in the process of team building - Establish urgency and direction-All team members
need to believe the team has urgent and
worthwhile purposes - Select members based on skill and their
potential. not personalities - Pay particular attention to first meetings and
actions. Initial impressions always mean a great
deal. - Set some clear rules of behaviour. Rules
regarding attendance, discussion confidentiality
and contributions are very important and help the
team perform its tasks in the early stages
123- 5 . Set and seize upon a few immediate
performance. By establishing a few challenging
yet achievable goals members of the team can
start working together right a way a process that
forge them together. - 6 . Challenge the group regularly with fresh
facts and information. New information helps the
team shape a common purpose and set clearer
goals. - 7 . Spend lots of time together. Creative
insights as well as personal bonding are created
early on if the team members spend time together. - 8.Exploit the power of positive feedback,
recognition and reward. Positive or
reinforcing feedback helps the process of team
building and accelerates it -
124- The Operations Trainer is designed to Support
team building - Promoting and nurturing individual learning, team
building and organizational learning are key
elements in the implementation of IPOM
125Organizational Learning in the IPOM environment
- Individual learning and team building are
necessary steps in the implementation of IPOM - The players must learn how to coordinate effort
in an uncertain environment were "division of
labour" is important but the process is far from
being completely repeatable, players are
dependent on each other as the situation changes
rapidly in an unpredictable way - Individual leaning is the basis. but it is not
sufficient in a highly competitive, dynamic,
uncertainty environment were the coordinated
effort of many individuals is required
126- Tasks are not independent and the process is not
completely repeatable - Organizational or group learning is the process
of developing the ability of a group of
individuals to improve its performances working
as a team to achieve a common goal - Argyris and Schon (1978) define two levels of
organization learning - Organization learning involves the detection and
correction - Double loop learning
127- Successful implementation of IPOM depends on the
ability of the organization to create an
environment that encourages single loop and
double loop learning - Group learning is based on several mechanism one
of which is repetition - Other mechanisms are
- 1. The ability to collect and share knowledge so
that members of the group can learn from each
other's experience. - 2. The ability to learn from the experience of
other groups or organizations - 3. The development of an efficient group
decisions making process - 4. The ability to share and use information real
time.
128Teaching IPOM - the Operations Trainer
- The Operations Trainer is designed to provide the
teaching environment for IPOM.To achieve this
goalthe trainer is an integration of tree
different systems - A simulation system that can simulate a variety
of scenarios in great detail. - An information system that handles the
traditional tasks of transactions processing,
management information and DSS - An ERP like system composed of an integrated
database and a model base
129- The operation trainer supports individual and
organization learning in tree ways - As a tool for teaching individuals the concepts
of information and it use - As a tool for practicing traditional Operations
Management by assigning a group of students or
managers to manage the simulated plan - As tool for teaching IPOM and ERP concept by
assigning a group of manager or students to
manage a simulated plant were the whole group
serve as a team responsible for the integrated
process and sharing information
