Procurement means different things to people. We mean the activity of acquiring Information Systems (an Information System includes People, Technology, Networks, Data and Processes) and related resources. This must be approached strategically to achieve economies of scale and scope and to ensure sustainability. Procurement therefore includes or at least has a strong relationship to Sourcing, selection, contracting, implementation, & oversight (or benefits realisation).

Take a Quick Maturity and Posture Assessment here

IT posture is the sum of the attitude that an organisation has towards their IT function, and self-image that IT has of itself within that organisation. The result affects the role that IT plays (and can play) in the business – both positive and negative. It goes without saying that posture dramatically affects IT value perceptions (and realities).
 
This is not the full assessment, which is normally done as a workshop but this will give you a sense of some of the considerations.
