    Do you have a good Time Schedule?

    Evaluate your time schedule, before anyone evaluate it

    DCMA 14 Assessment checklist for your time schedule.

    Introduction

    It is very important to evaluate your time schedules as a planning engineer, in this topic we will discuss some important point and check list which you can use to revise your time schedule and evaluate it even before your submission.

    These points and check list could be list a best practice check list , which will help you to make a clear assessment for your time schedule – whether this time schedule is “ Baseline or As-built” , you can use this check list to validate your time schedule.

    We will describe the checklist with explanation for every item in these checks points, also we will explain the “DCMA” The Defense Contract Management Agency 14-Point Assessment Metrics.

    1. Logic “Open Ends”

    Check all the activities that are missing a predecessor, a successor or both.

    You can check this from primavera by exporting Log file, when you schedule the time schedule and you will find it in this log file.

    According to DCMA 14
    points check list
    : The number of activities that are missing a predecessor, a successor or both should not exceed 5% of the activities within the schedule.

    Fig.(1) – Open Ends Activities in Primavera  Log File.

    1. Lead

    Check identifies any incomplete (in progress or not started) activities that are carrying a

    Lead (also known as a negative lag).

    According to DCMA 14points check list: the negative lag percentage should be 0%.

    1. Lags

    According to DCMA 14points check list: Total number of activities with lags should not exceed 5% of the activities within the schedule.

    1. FS Relations

    According to DCMA 14points check list: Total number of activities with lags should not exceed 5% of the activities within the schedule.

    1. Hard Constraint

    According to DCMA 14points check list: Number of activities with hard or two-way constraints should not exceed 5%.

    1. High Float

    According to DCMA 14points check list:  Number of activities with total float greater than 2 months (44 working days) should not exceed 5%.

    1. Negative Float

    According to DCMA 14points check list:  No activities that are incomplete should have total float that is less than 0 working days.

    1. High Duration

    According to DCMA 14points check list:  The total number of activities that have duration longer than 2 months (44 working days) should not exceed 5%.

    1. Invalid Dates

    According to DCMA 14points check list:  There should not be any invalid dates in the schedule defined as activities with planned work in the past or actual work completed in the future indicated by all actual dates being prior to the data date and all forecast dates being on or later than this date.

    1. Resources

    According to DCMA 14points check list:  All incomplete tasks should have resources (hours/$) assigned. This check verifies that all tasks with durations of 1 or more days have $ or resources assigned.

    1. Missed Activities

    According to DCMA 14points check list:  Number of activities that have slipped from their baseline dates should not exceed 5%..

    Identifies tasks that are supposed to have been completed (prior to the status date) with actual or forecast finishes after the baseline date, OR have a finish variance greater than zero

    1. Critical Path Test

    According to DCMA 14points check list:  This check evaluates the project’s network logic, particularly for the critical path and is a

    ‘what-if’ test performed directly on the schedule. Its intent is to identify a current critical path activity, to grossly extend its remaining duration, and note if a corresponding extension occurs to the project completion date.

    1. CPLI (Critical Path Length Index)

    According to DCMA 14points check list: Calculation of the Critical Path Length Index (CPLI) verifies that the critical path makes sense and that the critical path is “believable” Ratio of critical path length + total float to the critical path length should = 1
    (>1 favorable; <1 unfavorable).

    1. BEI (Baseline Execution Index)

    According to DCMA 14points check list:  BEI is the ratio of the number of tasks Completed to the number that should have been completed by the status date. BEI should be > .95 (>1favourable; <1 unfavorable).
