BIS4430IS Planning
(Unit 5)
Laudon & Laudon, 10th Ed., Chapter 14
2
What is a Business Plan?
Starts with some kind of statement, general or explicit, stating where an organisation would like to be
A strategic business plan contains:• Organisation’s mission and future direction• Performance targets• Strategy
3
What is an IS Plan?A road map indicating
• the direction of systems development (the purpose of the plan),
• the rationale,
• the current systems/situation,
• new developments to consider,
• the management strategy,
• the implementation plan, and
• the budget. (Laudon & Laudon)
4
What is an IS Plan?
An IS plan includes:
• activities that help to achieve the goals
• a program of measure
• means of implementing changes
A statement how management see ISs in the future Effy Oz
See page 497 of Laudon and Laudon
5
Need for a Plan
• IS which are complex and/or which aim for distinct competitive edge require long-range
planning.
• Decisions on future IS have organisation-wide impact, affecting turnover, and staff motivation, and therefore, IS planning should be carried out within the larger framework of corporate planning.
6
Need for Planning
• Investment in IS has increased significantly because of the influx of products and support based on new computer and telecommunication technology. Such commitments require careful and systematic
planning.
7
Need for a method
• to provide a structured and systematic approach
• provide basis for development of IS that reflect more accurately the needs of the organisation
• provide IS group with direct link into corporate planning
8
Variety of terms used:
• Information Systems Planning (ISP)
• Information Systems Strategic Planning (ISSP)
• Strategic Planning for Information Systems (SPIS)
• Strategic Information Systems Planning (SISP)
• Corporate Information Technology Planning (CITP)
9
In this unit we are looking at:
• Planning undertaken by an organisation in order to
determine its information systems requirements so that it
can meet its short term and long term needs
• The process of identifying the application portfolio that
will help the organisation in executing its business plans
and consequently realise its business goals and /or
the process of developing an application portfolio
with a high impact and the ability to create an advantage
over competitors.
10
Information Systems Planning
.. The planning of information systems used to support or shape an organisation’s competitive strategy, its plan for gaining and/or maintaining advantage’
(Rackoff, 1985 in Fitzgerald)
Two broad approached to SISP:
• IMPACT approach:
• ALIGN approach:
11
identification of a small number of IS applications that can give the organisation a competitive edge
the development of organisation-wide information architecture of applications to guide the creation of large databases and computer systems to support current business strategies
12
IMPACT approach
ALIGN approach Business goals
Competitive advantage
Value chain analysis
•Helps to identify critical points of inter-departmental collaboration•Concentrate on value adding activities and is independent of organisational structure•Pitches IS right into the realm of value adding rather than cost cutting
Weaknesses include:
• Only provides a high level information model – development and implementation issues are not addressed
• The focus is on operations not on data – does not provide suitable data structures
• Difficult to apply to organisations where the product is intangible, and where there are no obvious raw materials
13
(Pant and Hsu, 1995)
14
Approaches to Business IS planning
• Bottom-up planning
• Top-down planning
15
Bottom-up planning
• approach to planning is based on an organisation’s response to needs/problems
• mainly driven by middle managers
• does not allow a broad view of organisational needs and opportunities
• reactive rather than proactive
16
Bottom-up planning
Top management
Business units
IS will serve specific units well
Usually not conducive to enterprise-wide integration of systems
The process starts with individual concerns
Adapted from Effy Oz, 2000
17
Top-down planning
• also considered as goal-driven
• driven by senior managers
• proactive rather than reactive
• effective in creating strategies for overall business
• results in highly integrated Information Systems spanning the entire organisation.
18
Prerequisites for effective IS planning
• recognise IT as a indispensable resource
• understand that IT is a complex resource
• regard IT as owned by the entire organisation
• regard IS as a source for gaining strategic goals
• view IS as a tool to control power
The top management must:
Corporate mission
IS mission
The role of the IS in the corporation IS vision
The ideal technology (hardware, software, communications) for the corporation
IS strategic plan
Goals to be achieved IS tactical plan
Objectives and ways to achieve them
Plan for operations
Projects priorities staffing purchases fundingBudget
The steps of IS planning
(Effy Oz, 2006:386)
20
IS planning
• Critical Success Factor (CSF) planning
• Business Systems Planning (BSP) or Enterprise Analysis
• SISP
21
Strategic Analysis or Critical Success Factor (CSF) Planning
A small number of easily identifiable operational goals shaped by the industry, the firm, the manager, and the broader environment that are believed to ensure the success of the organisation.
L&L
Used to determine the information requirements of the organisation
22
Success factors – McKinsey and Company, by D. Ronald Daniel in 1961 ‘Management Information Crisis’, Harvard Business Review, Sept-Oct, 1961.
Critical Success factors – Jack F Rockart in 1979‘Chief Executives Define Their own Data Needs’, Harvard Business Review, March-April 1979, p81
Published later in 1986 in the book, ‘A Primer on Critical Success Factors’.
23
Measures that indicate the performance or efficiency of different parts of an organisation and its processes.
Bocij et al. (2006)
24
Critical Success Factor (CSF) Planning
underlying concept is that the success of the organisation is the sum of the success of individual business units

According to Rockart there are 4 basic types of CSFs:
• Industry CSFs resulting from specific industry characteristics
• Strategy CSFs resulting from the chosen competitive strategy of the business
• Environmental CSFs resulting from economic or technological changes
• Temporal CSFs resulting from internal organisational needs and changes
27
Industry CSFs
Organisational CSFs
Business Unit or Function CSFs
Manager’s CSFs
28
Critical Success Factor (CSF) Planning
• Identify the firm’s primary mission and objectives
• Executives identify CSFs
• Identify measures of performance
• Decide which measures are most important
Steps:
29
CSF Sources
• The structure of the industry
• Firm’s competitive strategy
• Firm’s industry position and/or geographic location
• Environmental factors surrounding the firm
• Temporary operating problems or opportunities
30
CSF Examples
• Improving customer relationship
• Improving supplier relationship
• Making the best use of inventory
• using capital and human resources efficiently and effectively, etc.
31
CSF Source of CSF Primary measures & Targets
Increase number of customers
Industry 95% customer retention rate; 15% new customers/year
Install customer service hot line
Strategy 90% customer queries answered in 1 hour
Increase number of customer service reps
Strategy 3 reps per 100 customers
Restructure capital structure
Environmental Lower cost of capital by 2%
Raise employee morale
Temporal Increase employee retention rate to 95%/year
32
Consider the case of a mail order supplier of clothes:
Objective: To increase market share by 5% per annum
CSFs: Effective advertising,
faster customer order processing,
faster distribution service
IS Applications: market research database and analysis, web based order processing,
automated delivery scheduling
33
Benefits of CSF Planning
• starts with a shared understandings of what is critical to the company help effective communication between executives
• influences in prioritising system development projects
• systems produces are more custom tailored
• takes into account the changing environment
• especially suitable for DSS and ESS
Weaknesses:
• Although useful and widely used, not enough to perform a comprehensive SISP on its own
• To be of value, need to be easily and directly related back to BU goals. According to Ward, generally looses its value when used below the 3rd level of hierarchy
34
(Pant and Hsu, 1995)
Weaknesses:
• Focuses primarily on management control hence internally focused rather than creative
• Do not draw attention to the value added aspect of information systems. CSFs facilitate the identification of IS which meet the key information needs of a BU/organisation. Not much work carried out to assess the value derived from these systems
35
(Pant and Hsu, 1995)
36
The Business System Planning (BSP) or Enterprise Analysis
• Developed in the 1970s by IBM
• Business oriented - provide focus on data
• involves top-down planning with bottom-up implementation
• assist an organisation in developing and establishing an information architecture
37
The Business System Planning (BSP)
- how they use information
- where they get information from
- what their environments are
- what their objectives are
- how they make decisions
- what their data needs are
Central method is to take a large example of managers and ask:
Subunits Functions Processes Data
38
The Business System Planning (BSP)
- While recognising data as a corporate resource, it does not provide a direct interface to conceptual and logical data modelling activities.
- There is also a lack of adequate definition of data components or use of current data nomenclature
- Nothing in the original methodology helps an organisation if its computing resource has become decentralised.
Missing elements:
Strengths:• BSP combines top down analysis with
bottom up implementation strategy -represents an integrate methodology
39
Weaknesses:• Considerable time and effort is required for
its successful implementation
• Requires a high degree of IT experience within the planning team
Business Systems Planning
BSP, in addition to its value for I/S planning, also made two other important intellectual contributions:
1. It helped introduce the process view of the firm. The popular Business Process Re-engineering of the 1990s was built on this concept.
2. It pointed out the need to de-couple data from the applications that use these data, i.e., data independence. This supported the database approach to systems development.

Ward et al.s’ Approach
aims to align IS development with current business needs and goals and to seek competitive advantage from them
42
The SISP Approach
‘the process of deciding the objectives for organisational computing and identifying potential computer applications which the organisation should implement’
Earl defines SISP as:

The Information Engineering Methodology (IEM)
• aims to align hardware and software resources to the corporate plan
• a continuous process of planning, implementation and management
• compares the formal business strategy with the actual

Earl's Multiple Method
Acknowledges that there is a diversity of reasons why organisations undertake ISSP.
suggests the use of a three level model as an aid to thinking about ISS
