As a Project Manager for Madeup Inc., you have reached a stage in your planning where you need to estimate the size of the most important component of the software. You use three approaches for estimating, each of which gives you a different result: beta distribution (5000 LOC), Blitz (4000 LOC), and Delphi (3000 LOC). Assuming you use the Incremental and Iterative Development Process, explain which estimate you will use and why? (Hint: look at the problem from the perspective of a project manager, not a developer)

Homework Answers

Answer #1

Answer:

  • One can see as a project manager that the variations are not dramatic between the estimates, and we estimate the most critical part of the program.
  • So, the option of the Project Manager becomes less a professional one and more a matter of staying on the safe side. You can go for 5000 LOC beta delivery to minimize uncertainties since it offers more optimistic predictions, and the blitz method provides performance based on past observation of prior ventures, and the Delphi method provides output based on developer knowledge.
