No. 3: IT is internal or outsourced
Binary Thinking: Organisations can get their IT services from an internal IT department or they can dispense with their IT department and their CIO and get all of their IT services under contract from an IT outsourcer.
Portfolio Insight: Both extreme options are illusions. Even organisations which have "fully" insourced IT employ contractors and purchase software and equipment, together with supporting services, from external parties. Organisations which have "fully" outsourced their IT still have internal staff involved in requesting, governing, specifying, procuring and supervising the outsourced services. The optimum model will be a carefully tuned combination of internally and externally provided products and activities.
