    Metrics

    I have query,
    1. In a customer driven metrics, if the customer says 1 Defect/KLOC is allowed, then how it will be distributed across phases.

    2. How the productivity is calculated when the porject requirements are given by the client itself, ie the projects starts from Design phase.

    Thanks in advance

    Re: Metrics

    For Question 1. On Defect distribution...

    Generally defect distribution across phases will be calculated as below:
    Defect Distribution for phase = (No: of defects per phase) / (Total defects) * 100


    Defect density will be calculated against the KLOC.
    Residual Defect density = (No: of Defects caught by customer / KLOC)

    Ex:
    If you have 10 KLOC, then
    Residual defect density = 1 /10 = 0.1 is allowed.

    Overall Estimated Defects = (Defect Density * Project Planned Effort)

    Estimated Defects for Phase = Overall Estimated Defects * Respective Phase Effort
    Distribution

    Actual Phase-wise Defects distribution =
    (Actual Defects Identified in the Phase / Total defects identified) *100

    Re: Metrics

    Heptoo - it is not the policy of most people here to provide answers to exam or interview questions. Even though the original poster can now look at your response and "study" it, and in doing so - show some resourcefulness; the answer you have provided is by no means comprehensive. Also, it may not be entirely applicable to the poster's question. Please align yourself with the implied "answers" policy. Thank you!
