This process works towards managing a highly pervasive and diffused IT as a resource that can improve organizational effectiveness in a highly uncertain environment.

3.1 Inverted-U: Law of Diminishing Returns
A study [5] suggests that too little SISP would result in insufficient understanding of the external and internal environment producing ill-conceived strategic alternatives and poor selections from them. Similarly too much SISP would require too much time causing opportunities to run by. Through the study it was established that the inverted -U exists for strategy implementation phase as shown in Figure2.

3.2 Optimization of Planning Process
 Through the use of Linear Goal Programming (LGP) mathematical approach to analyze IS investment projects a balance between strategic benefit (long term) and cost-benefit(short term) can be achieved[8]. An LGP model optimizes goals rather than objectives by transforming objectives into goals, assigning an appropriate target level to them with acceptable deviations and ranking each of the goals.
