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.

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.
