- The Laudon and Laudon book, Management
Information Systems (Seventh Edition) - Chapters 1 (1.1) and
- all of Ch. 3
3The Organisation
- An organisation is a person or group of people
united for some purpose - to deliver a product, a service, information...
- Many organisations are established for trade to
generate profit, but not necessarily. They may be
charities or government departments. They still
need management and information systems!
4Organisations
- Organisations process and use information in
order to produce outputs for an environment. - Most organisations are not designed primarily for
processing information - they deliver services or
products. Examples - a newspaper delivers news and opinions,
- The Department of Social and Family Affairs
deliver pension and unemployment services.
5Organisations (2)
- The previous definition of an organisation
implies that introducing new technology changes
the way inputs are combined into outputs, - i.e. a technical rearrangement of machines or
workers. - This has the effect of changing procedures and a
lot of information ( information systems).

7Organisations (4)
- Appropriate information systems need to be
developed to support the activities of an
organisation - day to day activities,
- longer term goals and objectives,
- strategic management.
- An organisation needs information about
- its own internal activities and operations,
- the markets and industry within which it operates.
8Types of Organisation
- There are four commonly recognised structures for
organisations that are sometimes defined as
types - Functional
- Product (sometimes referred to as Project as an
alternative) - Bureaucratic
- Matrix
9Types of Organisation (2)
- Functional - aligned with the basic managerial
functions, such as Purchasing, Sales,
Personnel(i.e. structured with Departments) - These are often hierarchical. It may be difficult
to produce systems that span several functions
(information) systems may overlap departments but
may need to be different. - Product - activities are grouped by output or
products. - These often deliver specific expertise but also
duplication of activities if individuals are
working independently.
10Types of Organisation (3)
- Bureaucratic having many detailed rules and
procedures - These are often hierarchical, mechanistic and
impersonal. - Matrix a hybrid of Functional and Product.
11Types of Organisation (4)
12Types of Organisation (5)
13Types of Organisation (6)
14Differences in Organisations
- Organisations may have (usually do have)
different structures or shapes. - They have
- Different goals
- Benefit different groups
- Different leadership styles
15Differences in Organisations (2)
- Different goals
- coercive (military, prison), utilitarian
(businesses) normative (religious groups,
universities). - Benefit different groups
- members (credit union), clients (welfare agency),
owners (business). - Different leadership styles
- democratic, laissez-faire (leadership absent),
technocratic (technology based), bureaucratic
(rule based), authoritarian.
16Differences in Organisations (3)
- Organisations exist in different environments
- turbulence (rapid technology change), complexity
(multiple competitors). - Perform different tasks
- programmed routine tasks (inventory reorder),
semi programmed (production scheduling),
unprogrammed (selecting strategy, e.g.
consulting). - Use different techniques technology.
- craft (woodworker), batch routine (assembly
line), continuous process (oil refinery).
17Types of Organisations
- Example- entrepreneurial structure
- A simple structure
- Young, small entrepreneurial firms in fast
changing environments. - Dominated by entrepreneur and managed by single
CEO (Chief Executive Officer). - Information systems are sometimes poorly planned
and significantly behind fast-breaking production
developments. (Usually because there is no
information Systems professional at work
continually.)
18Entrepreneurial Structure
The focus is on sales, rather than innovation
19Types of Organisations (2)
- Machine bureaucracy
- A large classic bureaucracy.
- It exists in slow changing environment, producing
standardised products. - It is dominated by strategic senior management
that centralised information flow and decision
authority. - It is likely to be kept in functional divisions
(manufacturing, finance, marketing, human
resources - departments.) - Information systems tend to be large-scale, well
planned but limited to such functions as
accounting, finance, simple planning and
administration.

21Types of Organisations (3)
- Divisionalised bureaucracy
- A combination of many machine bureaucracies, each
producing a different product or service, topped
by a central headquarters. - Suited to slow changing environments and
standarised products. - Organisations are divisionalised so tend to
operate in different environments (i.e. for each
product or service). - Information systems are elaborate and complex to
support central headquarters financial planning,
reporting requirements and operational
requirements of the divisions.

23Types of Organisations (4)
- Professional bureaucracy
- Example a knowledge-based organisation selling
professional service. - Suitable for slow changing environments and skill
sets. - Dominated by Department Heads with weak
centralised authority. - Professional members create product or service.
(Consider systems analysts and programmers of a
software company.) - Example problem poor central administration
system while working with sophisticated
knowledge-work support systems.
24Professional Bureaucracy The Hospital Example
Board of Trustees
Executive Committee
Council of Physicians
Exec Director
Director of Admin Services
Director of Hosp Services
Director of Nursing
Director of Prof Services
Medicine
Surgery
Radiology
Pediatrics
- Other examples law firms, accounting firms,
schools.
25Types of Organisations (5)
- Adhocracy the structure is arbitrary
- Example a task force organisation.
- Characterised by large groups of specialists
organised into short-lived, multidisciplinary
task forces focusing on new products. - High tech firm that must respond to rapidly
changing environments or markets (or derive money
from government contracts). - Innovative and flexible but with weak central
management. - Information systems might be poorly developed at
the central level, but often advanced within task
force.
26Adhocracy The Oil Refinery Example

27Business Organisations
- Business organisations vary in size from huge
international companies to private individuals,
including - manufacturing and commercial companies,
- central and local government departments,
- financial institutions,
- administrative organisations,
- service agencies,
28Business Organisations (2)
- Product flow is the flow of raw materials to
finished goods. - Information flow is the creation and movement of
the administrative and operational documentation
necessary for product flow and for providing a
service. - Business Information Systems support information
flow and provide information to companies to
assist in achieving their aims.

30Organisation Functional Areas/Processes
- Main work areas inherent in most companies are
- Accounts (including billing, collection, payment,
payroll) - Personnel (including recruitment, professional
development, etcetera.) - Sales (and Marketing)
- Purchasing
- Inventory / stock control
- Production
31Example - Payroll
- Payroll accounting
- Dealing with payment of employees.
- Requires a personnel administration system which
provides information on employees personal
details and terms of employment. - Requires a payroll system
- computation of gross earnings
- computation of deductions and net earnings
- accounting (distribution and updating of ledgers)
32Example Payroll (2)
- Typical documents (electronic or otherwise)
- Time reports/time cards
- Payslip
- Bank direct credit list - Electronic Funds
Transfer (EFT) - Cheques
- Accounting reports - deduction and cost analyses
- End of year documents (such as P60s)
- Audit and control
- Employee wage history
33Example - Sales
- Order Control ensures that customer orders are
received, processed and fulfilled efficiently and
in organised way. - Sales Accounting deals with monetary side of
customers orders, invoicing, payment etc. - Typical functions
- Dealing with enquiries re price, availability
- Checking credit ratings,
- Validating orders,
- Handling customer complaints,
- Checking the status of orders.
34Example Sales (2)
- Typical documents
- Customer orders
- Sales invoice
- Sales statements (for account customers)
- Sales analysis reports
- These may be used to forecast sales and plan
marketing activities.
35Example - Marketing
- Marketing is the provision of goods and services
to meet customer needs. - Typical functions
- Monitoring competitors,
- Liaising with existing customers and clients,
- Market research,
- Identification and follow up of leads,
- Product or service promotion.
36Example - Purchasing
- Purchasing ensures that materials, equipment,
tools, etc are available at the right time, right
place and at the right price. - Typical functions
- Obtaining quotations from prospective suppliers,
- Placing orders with suppliers and monitoring
delivery, - Checking and handling goods received,
- Passing details of goods received to accounts,
- Checking supplier invoices before payment,
- Maintaining supplier details re price, quality
etc.
37Example Purchasing (2)
- Typical documents
- Purchase order (PO)
- Good Received Note (GRN)
- Delivery docket
- Purchase invoice
- Cheque or credit transfer (EFT)
- Purchase records (supplier records)
- Purchase analyses - measure supplier efficiency,
costs per work area, job costing
38Example - Stock Control
- Stock (inventory) control is the monitoring and
decisions regarding the items held in stock. - Stock is the buffer between supply (production or
external entities) and demand (customers or
internal entities if the product is used
on-site.) - Stock costs money it is important to minimise
the money held in stock and still meet demand
this often leads to JIT inventory control. - Just In Time - JIT - computer systems monitor
supply and demand continuously and trigger rapid
resupply when necessary. This requires close
cooperation with suppliers.
39Example - Stock Control (2)
- Typical functions
- Maintenance of stock level records
- Issue of stock
- Identifying and monitoring reorder levels
- Managing outstanding orders
- Stock valuation (stock check) and reconciliation
- Information systems complexity depends on the
number of stock items, turnover rate and the
number of dispersed stores.
40Example - Stores Control
- Stores control is the methods of operating the
stores or warehouses, i.e. storage space,
handling equipment, security, packaging,
labelling. - It is determined by
- size, weight and value of stock items
- flammability, stability (e.g. shelf-life) and
identification.
41Example - Stores Control (2)
- Typical documents
- Materials request,
- Purchase requisition
- Inventory transfer
42Example - Production
- Production designs and develops the product.
- Production planning covers what to make and how
to make it. - Production control ensures planning is achieved
by monitoring and control of machines, processes
and people involved in production.
43Example Production (2)
- These areas generate a huge amount of raw data
and require considerable amount of information to
control. - Production is an area subject to considerable
automation - CIM - Computer Integrated Manufacture
- CAD/CAM Computer Aided Design/Computer-Aided
Manufacture
44Example Production (3)
- Information required for production control
- Material requirements per time period (Man
Hours or Unit Time). - Quantities of components and subassemblies per
period. - Amounts of equipment, machines, tools required
per stage. - Amount of labour category required per stage.
- Progress of each job, reason for delays.
45Example Distribution
- Distribution receives the finished goods from
production and ships the product to the customer.

48Management of Organisations
- The traditional view models organisations as
having three levels of management - Strategic
- Tactical
- Operational
49Management of Organisations (2)
- Strategic level management is responsible for
overall strategy and direction - - typically, top level management.
- Tactical or middle level management ensure
policies for achieving the strategic objectives
are carried out - - typically, heads of departments.
- Operational level management are responsible for
the day to day activities - - typically, foremen, supervisors, team leaders
50Business Information
Information types Strategic (trends,
patterns, decision making)
Information types Middle/Tactical
(summary, prediction and control)
Information types Operational (summary, short
term, real time)
51Information for Strategic Management
- Strategic information
- Answers questions like What markets should we be
in? or Where do we locate the new factory? - Is highly selective and summarised and usually in
graphical form - Likely to originate outside the organisation
- Has value for a longer period
- Requires high degree of experience and judgement
in its application - / continued
52Information for Strategic Management (2)
- Decisions based on this information tend to be
unstructured. - Example - patterns of expenditure from market
surveys or trade publications, market
availability and penetration figures.
53Management Information
- Management Information for monitoring and
control - Answers questions like Of what (product/service)
are we selling most? or Are the sales team
meeting their targets? - Needs to be condensed and summarised information
in the form of reports, graphs and tables,
forecasts. - Is usually derived from information collected at
operational level. - / cont
54Management Information (2)
- Is shorter term information (months), concerned
with the departmental level. - Example - sales analyses, sales forecasts,
production schedules.
55Operational Information
- Operational Data for enabling and recording
routine business activity - Answers questions like What is the stock level
for a given product? or Can this customer be
given credit? - Is very detailed, highly specific and generated
internally. - Is short term (hourly, weekly), used for
decisions concerned with immediate situation. - / cont
56Operational Information (2)
- Structured decisions
- Examples - stock levels, customer order details,
overdue purchase orders.
57Information Purpose and Example of Systems
- Strategic Management
- modelling and simulation for decision support,
- financial models and profit margin change
simulations. - Middle Management
- monitoring and control of current information,
- production planning, sales forecasting, market
research. - Operational Management
- transaction processing,
- Stock Control, Payroll, Accounting

59MIS, DSS, EIS Systems
- Management Information System (MIS) - computer
system that provides management information - A user will normally have to access one or more
databases to get the information required. - Decision Support System (DSS) supports decision
making i.e. provides information on demand (ad
hoc) and as simply as possible.
60MIS Management Information Systems
Screen-dump example of an MIS interface
61DSS Decision Support Systems
Screen-dump example of a DSS interface
62EIS Executive Information Systems
Screen-dump example of an EIS interface
63MIS, DSS, EIS Systems (2)
- Simple DSS systems provide information for
manager to make decision - Sophisticated systems
analyse data according to algorithms and produce
recommendations. - It is necessary for DSS to have access to a wide
range of software and large corporate databases
so that facilities needed to make decision can be
accessible.
64MIS, DSS, EIS Systems (3)
- MIS/DSS usually have graphical interface - need
to provide information in simple and easily
assimilated presentation - graphs and histograms,
- drill down and hot spots features.
- Simulation DSS - allows interactive modelling
- values can be changed to see effect on business.
- What if scenarios.
65MIS, DSS, EIS Systems (4)
- Executive Information Systems (EIS) are
integrated systems to suit senior management - senior management historically have been
resistant to systems - but this has changed a lot
in recent years out of necessity.
66MIS, DSS, EIS Systems (4)
- Executive Information Systems provide
- decision support, (DSS)
- information retrieval from corporate databases,
ad hoc reporting, - powerful display and multimedia capabilities,
- presentation facilities, e.g. PowerPoint,
- communications, e.g. e-mail, fax,
- organisational support, electronic diary, etc.
- The user interface is important. (Executives do
not hack.)
67Where to Next?
- The management of organisations often has several
levels. - Each level deals with somewhat different
information and data so they have different
information systems requirements. The structure
of those systems can be identified and designed
by the process of systems analysis. - By the way, what is information? What is a
system? What are Management Information Systems?
We can look at these things next.
