Computer ManagementDefinitions (after Martin et al.)

Information technology - Computing, telecommunications and automation technologies used to capture, store, process, communicate, present and use data and information.

Information system - the collection of hardware, software, procedures, documentation, forms and people responsible for the capture, movement, management and distribution of data and information.

Stages of Growth ModelNolan and Gibson (1974)

Initiation - Computers are introduced to the organisation by enthusiasts. No management interest and no long term plan.

Contagion - Unmanaged growth when the technocrats provide solutions without considering organisational requirements.

Control - Management take control and apply formal budgeting and planning. Structures and roles are clarified.

Integration - Eases management control to encourage innovation. Re-organises the IS function and identifies user accountability. Expenditure on integration architecture.

Data Administration - The importance of corporate data drives policy at this stage. Cross-functional data access.

Maturity - A fully co-operating MIS triad. A balance between stability and innovation, control and chaos and between autonomy and cohesion.

Degree to which ITdevelopments will createcompetitive advantage.

Degree to which the firm isfunctionally dependent onIT today.

Strategic GridMcFarlan and McKenney (1982)

Strategic - Firms that are heavily dependent on IT to deliver their everyday product or service, e.g., banks and insurance companies.

Turnaround - Firms that are not heavily dependent on IS at present but will look to their IS function to provide them with competitive advantage in the future.

Factory - IS applications are not seen as providing competitive advantage although they are heavily relied on for day-to-day operations.

Support - Use administrative systems to improve efficiency and have islands of specialist systems which innovate the manufacturing process

IS resource modelsSullivan-Trainor (1989)

The service model - The organisation may not yet understand what IS it requires so it relies on IS professionals to provide a service.

The partnership model - Close alignment between IS and the functional lines in the user community.

The vendor model - IS is considered to be a cost centre that sells its services to the user community.

The expansion model - IS create a flexible architecture for common systems to accommodate the user community's growing needs.

The strategic advantage model - IS and the user community working in harmony to create systems for competitive advantage.

LocationRobson (1994)

Centralised - One single-access function. IS provides the service and retains control. Facilitates consistent data formats, compatibility and security.

Decentralised - A number of single-access functions. A collection of mini “DP” departments.

Distributed - Lots of connected functions. IS is a number of laterally linked multi-service providers.

Devolved - As distributed with significant end-user control over processing and development.
