ITPEC FE Morning October 2021 Question 62
In an evaluation of an IT investment, a preliminary evaluation, an interim evaluation, and a posteriori evaluation are conducted in accordance with the planning, execution, and completion of individual projects. Which of the following is a description of the preliminary evaluation?
Explanation
Set an effect goal from the investment purpose and give management what it needs for the go/no-go decision — the preliminary evaluation happens before the investment is approved.
The three evaluations follow the life of an IT investment project:
- •Preliminary (planning): set the effect goal from the purpose of the investment and judge whether to execute at all
- •Interim (execution): compare the plan with actual results, analyse the causes of any gap, and change the investment amount or goal if needed
- •A posteriori (completion): check whether the effect goal was reached and consider improvements
Answer (b)
Why not others:
- •(a) — a variance between plan and results only exists once the project is running, so this is the interim evaluation
- •(c) — evaluating at milestones when the effect should have been attained takes place during and after execution (interim and a posteriori), not before the decision to invest
- •(d) — assessing whether the preset effect goal was achieved is the a posteriori evaluation
Key rule: Match each evaluation to its question: before, should we invest; during, are we on plan; after, did we get the effect.
