- An input-output phenomenon
- Input resources output products by
products
Figure 1 Fundamental Product Process Relationship
4WORK PROCES
- A process is defined as the sequential
integration of people, materials, methods, and
machine in an environment to produce added
outputs for customers. A process convert
measurable inputs into measurable outputs through
an organized sequence of steps. Four group or
people are involved in the operation and
improvement of processes (Tenner and DeToro,
1994) - Customers the people for whom the output is
being produced - Work group the people who work in the process
to produce and deliver the desired output - Supplier the people who provide input to the
work process - Owner the person who is responsible for the
operation of the process and for its improvement
5INTRODUCTION
- Two general types of strategies exist for
creating products that meet or exceed customer
needs and expectations (1) process focused or
(2) product focused. - Process focus how we design and build our
products (i.e., how we combine inputs and
processes). - Product focus what we design and build.
- Concern and formulate strategies for both
process and product.
6PROCESS
- PROCESS A bound set of interrelated work
activities, each having prescribed inputs and
outputs. - Can be material, equipment, other tangible
objects, or various kinds of information, are
converted by a series of activities into an
output provided to a recipient. - RECIPIENT
- -gt can be either an external or internal
customer. - -gt An external customer is a person or
organization that pays for the service or
products received. An internal customer can be
a department, a group (in case of an internal
operation), or some other processing
equipment and machinery. - -gt can be a location where the process's outputs
are stored for future use (e.g, a warehouse).

boundaries in an organization - This simplified definition of a process needs

New Product Development
9PROCESS
- According to Melan (1993), a process can be
defined by its four key functions - 1. Endpoints
- 2. Transformations
- 3. Feedback
- 4. Repeatability
- 1.Endpoints
- defined as its inputs and outputs.
- endpoints categories
- a. Inputs
- b. Outputs
- c. Customers
- d. Catalyst event
10PROCESS
- INPUTS
- can be equipment, materials, methods, or the
environment. - OUTPUTS
- products or services.
- CUSTOMERS
- users of the products or services.
- can be either internal or external to the
organization. - the ultimate judges of the quality of the process
outputs. - the primary customer is the most important
customer for any
product or service. - CATALYST EVENT
- can be classified as an input as well as an
independent endpoint. - the single event that signals the beginning of
the process. - it establishes the initial boundary of the
process.
11PROCESS
- 2. Transformations
- Can be classified into three categories.
- Physical
- Locational
- Transactional
- Physical transformation
- changes some tangible item, such as raw or
semi-finished material, into another state. E.g.
act of melting down pellets and injecting the
melted plastic into a mold. - Locational transformation
- also changes physical items.
- it changes the location of objects or materials
and does not change the materials in any other
physical manner. E.g.the movement of plastic
pellets from the warehouse to the shop floor or
the movement of the final product from the shop
floor into the storage or shipping area.
12PROCESS
- Transactional transformation
- involves the modification of nontangible items.
- these items include the electronic movement of
money in banks, the sales of stock by
stockbrokers, or the assembly of marketing
research data by advertisers. - the primary input item is information or data.
- the transformation process could involve the
modification of data.
13PROCESS
- 3. Feedback
- involve communication and evaluation channels by
which the transformation activities are modified,
or corrected, to maintain the desired attributes
of the output. - every process requires feedback to regulate its
output. - feedback can take many forms.
- it can occur as information from the output side
of the process or from check - points inside the
conversion processes. Feedback can also take the
form of economic information, such as gross sales
revenue, which is used to evaluate the operation.
14PROCESS
- Feedback ensures that the process is effective,
efficient, and achieving its desired output. - Feedback can be divided into five categories.
- a. Customer needs and expectations
- b. Specific customer targets
- c. The voice of the customer
- d. Specific process targets
- e. The voice of the process
- involve information from the output of the
process. - involve information from within the process.
-
15PROCESS
- 4. Repeatability
- a process is or can be executed regularly in the
same manner with the same output. - Some processes are continuous, while others
operate cyclically or intermittently. - The process of assembling cars on a production
line is a continuous process. - Building custom cabinets for new houses is an
intermittent process. - But, whether a process is continuous or
intermittent, it must be repeatable.
16PROCESS CHARACTERISTICS
Whether a process involves transformations of
a physical, locational, or transactional nature,
it has 10 common characteristics. 1. Clearly
defined ownership 2. Boundaries 3.
Capacity 4. Documentation 5. Control points
6. Effectiveness 7. Efficiency 8.
Adaptability 9. Measurements 10. Corrective
action-An input-output phenomenon
17PROCESS CHARACTERISTICS
- 1. Clearly defined ownership
- Traditionally, the ownership of physical and
locational processes has been clear and
explicit. - The process owner was the departmental manager.
-
- Understood the organizational mission and the
process's output had personal responsibility
and accountability for the process and its
output. - The manager's performance was judged by
quantifiable standards, such as cost, schedule,
and quality. - Recently, process ownership has gradually
shifted toward empowered work groups and
self-directed work teams.
18PROCESS CHARACTERISTICS
- and in these teams, employees are assuming some
traditional roles of management. - the basic ideas remain the same.
- the process owner, whether an individual or a
team, is responsible for yield, cost, quality,
and schedule. - the process owner must manage the process to the
targets set on this standard. - the process owner has the authority to change the
process to maintain its desired outputs.
19PROCESS CHARACTERISTICS
- Boundaries
- Boundaries are the beginning and end of a
process. - Physical and locational processes have clearly
defined boundaries. - The final output from and the input(s) required
by these processes are clear and unambiguous. - However, the boundaries of transactional
processes are harder to identify. - Further, output specifications for transactional
processes may not truly reflect customer
requirements, and input specifications may not
achieve the desired output specifications with
the existing processes.
20PROCESS CHARACTERISTICS
- A lack of understanding about the input
specifications and the output specifications is
common in many business processes. - But in a well-managed transactional process,
specification problems are minimized through
conscious effort aimed at classifying the work
product as it proceeds from one operation to
another. - Thus, the boundaries of a well-managed process
are well-defined and controlled.
21PROCESS CHARACTERISTICS
- 3. Capacity
- Capacity is the output rate of the process.
- Capacity is usually expressed in terms of design,
or theoretical, capacity and effective capacity. - Thus, design capacity is stated without
consideration for such matters as equipment
reliability, maintenance, or personnel factors
such as learning curves, absenteeism, illness,
and so on. - These considerations, when allowed for, enable
effective capacity to be calculated.
22PROCESS CHARACTERISTICS
- 4. Documentation
- A detailed record of work flow in processes.
- Can be written in great detail, or it can be a
collection of various bits of data. -
- Provides a permanent record of the physical
transformation taking place in a production
process. - Provides a reference point from which the
repeatability of a process can be measured, and
it provides a baseline from which any changes can
be measured.
23PROCESS CHARACTERISTICS
-
- Serves as both a training and reference aid
for the - personnel involved in the process.
- Typical documents include process flowcharts,
assembly drawings, and
routings. - Process flowcharts graphically describe the
sequence of operations in the process. - Assembly drawings show how a product is
- constructed.
- Routings describe operational steps that
accompany the process flowchart.
24PROCESS CHARACTERISTICS
- 5. Control points
- Regulate the quality of work or provide
feedback. - Established to manage the natural variation
that - occurs in physical processes.
- 6. Effectiveness
- It measures feedback against process goals.
- Effectiveness is best assessed by measurement,
- both internal and external.
- External effectiveness measures must reflect
- customer requirements.
- Internal effectiveness measurements must
reflect - both external and internal customer
requirements. - It should proceed from the external boundary
to the - starting boundary of the process.
25PROCESS CHARACTERISTICS
-
- Integrated flow diagrams that reflect established
requirements are useful for measuring
effectiveness. - Ineffectiveness is often easier to identify than
effectiveness. - These are some symptoms that suggest an
ineffective process. - - Customer complaints
- - Inconsistent output quality
- - Lack of awareness of output quality
- - Absence of a corrective-action system
- - Lack of interest in the customer
- - Long response times in correcting problems
26PROCESS CHARACTERISTICS
- Efficiency
- A measure of the output against the resources
required to achieve that output. - It reflects how productive the internal
operations are and how effectively resources are
used in the process. - A traditional measure of efficiency is the ratio
of output to the capacity of a process. - Inefficiency is easier to identify than
efficiency. - These are some symptoms of inefficiency.
- - Multiple off-line inspections
- - Redundant, unnecessary, or nonvalue-added
activities - - Corrective actions such as rework and
reconciliation - - Supplier problems (e.g poor quality or
late deliveries) - - Excessive costs of value-added activities
(E.g high - production costs)
27PROCESS CHARACTERISTICS
- 8. Adaptability
- The ability of the process to adjust to change -
either technological or output changes. - A process responses to changing conditions such
as output requirements, internal constraints, and
input quality. - A process is adaptable if it can be changed to
meet new requirements without significant
modifications. - May require some work flow, personnel, and
equipment changes when a process change is
needed, but the process should remain largely
intact. - Processes that lack adaptability tend to be
limited in - nature equipment capability (capacity,
throughput, cycle times) or human aspects
(skills, flexibility, - resistance to change other human factors).
28PROCESS CHARACTERISTICS
- Measurements
- A statistical basis for controlling the flow of
work and managing variation _at_ provide a basis for
feedback. - Continuous measurements are inherent in any well-
managed process (meet specifications). - Process adapt to the natural variations that
occur. - Relied only on end-of-line measurements, or final
quality controls approach costly in terms of
scrap and rework. - Statistical techniques e.g Pareto analysis and
variation charts, are useful for managing
repetitive operations. - Need to measure products against the requirements
of the process without removing the product from
the process.
29PROCESS CHARACTERISTICS
- 10. Corrective Action
- The action required to correct for natural
variation in a process. - Internal feedback from measurements at one or
more control points identifies the need for
corrective action before subquality products are
produced. - This process is quickly adjusted to correct for
the variations and the processs effectiveness
and efficiency do not suffer despite the natural
variations. - Feedback and corrective action are the heart of
prpocess control, without them the process loses
its repeatability, quality and consistency.
30ANOTHER VIEW
- A process can also be categorized by its
operatinonal environment 2 categories of
operating environment are manufacturing and
service organizations. Both use the same three
transformation types but service process have 5
features that distinguish them from manufacturing
processes (Lowenthal, 1994) - i. Degree of customer contact vary in degree
of customer contact. Contact ranges from
virtually none eg life insurance process to
complete contact eg. Dental treatment. In
contrast traditional manufacturing processes
have little or no contact with customer. - ii. Intangibility cannot be touch or felt by
customer. -
- iii.Immediacy the catalyst event of a service
organization process occurs at the point of
customer contact
31ANOTHER VIEW
- iv. Nonaccumulation since service is an
experience rather than a product, output from
service processes cannot be accumulated or
inventoried - v. Labor intensiveness service processes are
accomplished by a wide range of people, capital,
and automation. Tend to be more labor intensive
such as legal, retail hotel and hospital
services. -
32PROCESS CHARACTERISTICS
Table 1 Differences between service and
manufacturing processes
Characteristic Service Manufacturing
Ownership Tends to be ambiguous or has multiple owners Usually clearly defined
Boundaries Often unclear, fuzzy Clearly defined
Control points Often nonexistent Clearly established and defined
Measurement Often nonexistent, hard to define Easy to define and manage
Corrective action Usually done reactively Performed during and external to the process
- Both manufacturing and service processes
contain the - 10 characteristics outlined.
- Thoroughness and attention paid to these 10
characteristics vary - depending on the environment.
33PROCESS MANAGEMENT
- Pall (1987) identifies six ingredients that are
essential for process management - Ownership Assign responsibility for the design,
- operation, and improvement of the process.
- 2. Planning Establish a structured and
disciplined - approach to understand, define, and document
all - major components in the process and their
- interrelationships.
- 3. Control Assure effectiveness all outputs are
predictable - and consistent with the customers'
expectations. - Measurement Map performance attributes to
customers'requirements, and establish criteria
for the accuracy, - precision, and frequency of data acquisition.
- 5. Improvement Increase effectiveness of the
process by - permanently embedding identified
improvements. - 6. Optimization Increase efficiency and
productivity by - permanently embedding identified improvements.

35PROCESS IMPROVEMENT
- People involved in the operation and improvement
of processes - Customers the people (or person) for whom the
- output (product or service) is being
produced. The - people who will use the output directly or
who will - take it as input into their work process.
- 2. Work group the people (or person) who work in
the - process to produce and deliver the desired
output. - 3. Supplier the people (or person) who provide
input to - the work process. The people in the process
are in - fact the customers of the supplier.
- 4. Owner the person who is responsible for the
- operation of the process and for its
improvement.
36IDENTIFYING KEY PROCESSES FOR IMPROVEMENT
PROCESS IMPROVEMENT
- Six questions by Geary Rummler Alan Brache
(1988) - Which products and services are most important to
the customers? - What are the processes that produce these
products and services? - What are the key ingredients that stimulate
action in the organization, and what are the
processes that convert these stimuli to outputs? - Which processes have the highest visibility with
customers? - Which processes have the greatest impact on
customer-driven performance standards? - Which processes do performance data or common
sense suggest have the greatest potential for
improvement?
37PROCESS IMPROVEMENT STRATEGIES
PROCESS IMPROVEMENT
- Three different approaches for improving the
efficiency or effectiveness of a process - Continuous improvement -a ladder, step by step
approach, also known as Kaizen. - Benchmarking - search for and emulate the best
available practices and processes. - Reengineering - the fundamental rethinking and
radical redesign of business processes to achieve
dramatic improvements

PROCESS IMPROVEMENT
39Process Improvement Analysis Hierarchy
TECHNIQUES FOR PROCESS IMPROVEMENT
40TECHNIQUES FOR PROCESS IMPROVEMENT
- 1. Elimination - eliminate non-value-added
activities. Instead of totally eliminate, replace
the functional essence of the activity with a
superior technology. - 2. Combination - combine activities in order to
extract process improvement. - 3. Change of sequence - examine the sequence to
see if a reordering will provide improvement. - 4. Simplification - examine activities with the
expectation of improvement through simplifying
the activities themselves. - 5. Addition If processes are clearly
ineffective, need to add a process step but
additions are our last resort.
41Process Improvement Model
SIX STEPS TO PROCESS IMPROVEMENT
42Step 1 Define the problem
SIX STEPS TO PROCESS IMPROVEMENT
- 1. Identify the output.
- 2. Identify the customers.
- 3. Define the customers' requirements.
- 4. Identify the processes producing these
outputs. - 5. Identify the owner(s) of the processes
-
43Defining the Problem in the context of the
process - example
Objective defined in terms of a specific results Restated in the context of the process Incremental process Improvement realized
Select and train 4 additional operators to support increased calls to computer users help line Improve systems to support computer users Annual opinion survey showed 15 improvement in employees views of computer support and no operators were added
44Step 2 Identify and document the process
SIX STEPS TO PROCESS IMPROVEMENT
- Flowchart
- commonly used tool for describing processes.
- enables to perform four following improvement
activities - Identify the participants in the process, either
by name, by position, or by organization. - Provide all participants in the process with a
common understanding both of all steps in the
process and of their individual roles. - Identify inefficient, wasteful, and redundant
steps. - Offer a framework for defining process
measurements.
45Step 3 Measure Performance
SIX STEPS TO PROCESS IMPROVEMENT
- The concepts of measuring performance at three
level process, output and outcome - Process define activities, variables and
operations of the work process itself - Output define specific features, values and
attribute of each product all service - Outcome define the ultimate impact of the
process and are dependent on what the customer
does with the product or service (customer
satisfaction)
46Step 4 Understand Why
SIX STEPS TO PROCESS IMPROVEMENT
- Offer methods to acquire the next level of
knowledge and to gain profound understanding of
the process - Never have so many
- worked so hard
- To accomplish so little
- 1. Have we distinguished the vital few from the
- trivial many?
- 2. Have diagnosed the root cause?
- 3. Do we understand the sources of variation?
47Step 5 Develop and Test Ideas
SIX STEPS TO PROCESS IMPROVEMENT
- Developing ideas for improvement begins with this
step. - These steps led to identify causes of the
principal problem. - Ideas for improvement must address the root
causes of the problem before it can be
implemented immensely in order to evaluate the
effectiveness in solving the identified problems.
48Step 6Implement Solutions and Evaluate
SIX STEPS TO PROCESS IMPROVEMENT
- This sixth step begins by planning and
implementing the improvements identified and
verified in the step 5. - Step 6 continues to measure and evaluate the
effectiveness of the improved process. - Finally, return to step 1 to begin the next
increment in the ongoing process of continuous
improvement.

standard operating procedures. - Establish a process to monitor and control
process performance
55Flow Charts
FLOW CHARTS
- Provides a clear view of how a process works.
- A pictorial representation of the steps in a
given process. - Steps are presented graphically in sequence with
symbolic shapes, and the flow of the process is
indicated with arrows connecting the symbols. - Should include every activity in the process.
- Should be the first step in identifying problems
and targeting areas for improvement.
56Purpose of flowcharting
FLOW CHARTS
- enable members to examine the order presented and
come to a common understanding of how the process
operates. - to describe an existing process or to present a
proposed change in the flow of a process. - help you see whether the steps of a process are
logical, uncover problems or miscommunications,
define the boundaries of a process, and develop a
common base of knowledge about a process. - brings to light redundancies, delays, dead ends,
and indirect paths that would otherwise remain
unnoticed or ignored.
57Steps in Flowcharting a Process
FLOW CHARTS
- Decide on the process to flowchart.
- Define the boundaries of the process the
beginning and the end. - Describe the beginning step of the process in an
oval. - Ask yourself "what happens next?" and add the
step to the flowchart as a rectangle. - When a decision point is reached, write the
decision in the form of a question in a diamond
and develop the "yes" and "no" paths. . - Repeat steps 4 and 5 until the last step in the
process is reached. - Describe the ending boundary/step in an oval.
58Symbols in a Flowchart
FLOW CHARTS
Defines the boundaries of a process shows the start or stop of a process.
Designates a single step in a process. Briefly describe the step inside the box.
A diamond signifies a decision point in the process. Write the type of decision made inside the diamond in the form of a question. The question is answered by two arrows--"yes" and "no"--which lead to two different branches.
A small circle that surrounds a letter signifies where you pick up a process on the same page represents a connection.
59Three main types of flowcharts
FLOW CHARTS
- 1. High-level flowcharts map shows only the major
steps in a process for a good overview.
602. Detailed flowcharts show a step-by-step
mapping of all events and decisions in a process.
FLOW CHARTS
613. Deployment flowcharts organize the flowchart
by columns, with each column representing a
person or department involved in a process.
FLOW CHARTS
62To construct an effective flowchart
FLOW CHARTS
- Define the process boundaries with starting and
ending points. - Complete the big picture before filling in the
details. -
- Clearly define each step in the process. Be
accurate and honest. - Identify time lags and non-value-adding steps.
- Circulate the flowchart to other people involved
in the process to get their comments.
63A completed flowchart enables you to
FLOW CHARTS
- Identify time lags and non-value-adding steps.
- Identify responsibility for each step.
- Brainstorm for problems in the process.
- Determine major and minor inputs into the process
with a cause effect diagram. - Choose the most likely trouble spots with the
consensus builder.
64- Conclusion
- we need to focus on process improvement in our
organization as a way to meet the customers need
and satisfaction and meet the global competition
to maintain the quality of our product or
services.
