It is essential to take into account what one already has

Techniques of Systems Analysis gives some advice about time phasing:

If it is the purpose of the study to recommend procurement and operation changes, it is often essential to take into account what one already has, and important to consider what one may want to have in the distant future. The recommended system should, therefore, consider the possibility of exploiting those things which one has and of having a salvage value for future systems. Also it sometimes makes a real difference exactly how the funds are to be disbursed on a year by year basis. While the Systems Analyst should not get into all the headaches of the executive, he should explicitly consider, if at all possible, everything which is important to his recommendations rather than make vague remarks about using or deferring to military or executive judgment.
