Title: 3.5 Corporate Information Systems Strategy


1
3.5 Corporate Information Systems Strategy
  • Chapter 5
  • Pg 66

2
What is a Corporate Information Systems Strategy?
  • A statement of the long-term objectives and goals
    for an organisations information system.

3
Describe the Factors Influencing an
Organisations Information System(s)
  • Management organisation and functions
  • Planning and decision-making methods
  • General organisational structure
  • Responsibility for information systems within an
    organisation
  • Hardware and software
  • Standards
  • Behavioural factors
  • Efficiency of information flows

4
Management Organisation and Functions
  • Managers do the following as part of their jobs
  • Organise and implement
  • Plan (strategically and tactically, depending on
    their level within the organisation)
  • Control and review

Back
5
General Organisational Structure
  • Information must be communicated up and down the
    various levels of a hierarchical structure to
    allow managers to make timely and effective
    decisions.
  • Back

6
Responsibility for an Info System within an
organisation
  • Data processing responsibility usually falls to
    IT dept
  • Responsibility of MIS usually less formal and can
    lead to problems
  • IT dept not aware of existence of systems set up
    by individual depts.
  • Can compromise data security (dept head not aware
    of DPA etc)
  • Most of such data can be duplicated for different
    depts (waste of time and resources).

7
Responsibility cont
  • Best Information Systems are those that are
    developed formally.
  • All data is kept together (data warehousing)
  • All managers have software capable of extracting
    info in a formal way they can use.
  • Data is not duplicated therefore consistent.
  • back

8
Hardware and Software
  • Many organisations have limited budget and have
    to make do with existing H/W and S/W
  • This means that often the optimum system cannot
    be developed.
  • back

9
Behavioural Factors
  • Attitude of staff to change is a very important
    factor. New systems need full co-operation of
    staff (especially senior managers)
  • If staff members are poorly motivated changes
    will be resisted.
  • Job security may become an issue with some staff.
  • back

10
Information Flow
  • Describe the methods and mechanisms of
    information flow within an organisation both
    formal and informal and the constraints imposed
    upon this by organisational structures.

11
Information Flows
  • Formal vs Informal
  • Many reports generated automatically and
    distributed as a matter of routine.
  • Daily stock lists
  • Monthly sales figures
  • Lists of overdue accounts
  • Other reports are asked for informally
  • Request after sales meeting for last five years
    sales figures to make future predictions.

12
Formal vs Informal cont..
  • Formal information requests eg form filling,
    authorisation by senior managers etc (SLOW!)
  • Informal requests generally much faster.

13
Efficiency of Information Flows
  • Without adequate flows of data and info to the
    various functions within the organisation, no MIS
    will be able to supply appropriate info at the
    right time and this will lead to bad decisions
    being made.
  • Factors that can affect those flows include..

14
Organisational Structure
  • An organisation with a flat structure has fewer
    levels and it is therefore easier to route the
    info to the most appropriate person.

15
Geographical Structure
  • Wider geographical structure can cause problems
    but latest technology no longer means distance is
    a hindrance.
  • videoconferencing
  • Distributed processing
  • All processing doesnt take place on a single
    site.
  • Although more complex to manage has the advantage
    of increased security.

16
What Can be Done to Review Current Information
Flows?
  • Inspect current input/output subsystems
  • Track the documents used for input/output into
    the system
  • Interview the end-users are they getting info
    at the right time?
  • Use questionnaires how satisfied are users with
    current info flows?
  • Examine requests made for developments to improve
    the current system
  • Inspect the reports and info from the current
    system.

17
Personnel
  • Understand the levels of task/personnel within an
    organisation
  • Strategic
  • Tactical
  • Operational
  • And relate the needs of these three levels to the
    information system

18
Planning and Decision Making
  • Can be at different levels
  • Strategic
  • Setting broad objectives and formulating a policy
    for the whole organisation
  • Tactical
  • Setting medium to short-term objectives.
  • Operational
  • Dealing with jobs in hand.
