PMP Exam – Critical Path Part 2

Sir Ganttalot helps you prepare for the PMP exam by explaining Critical Path and Float/Slack analysis. This Part 2 video explores in detail the forward/backward pass approach to identify the Critical Path in a project network and to determine the float/slack for non-critical tasks. The Part 1 session covered a quick and easy “eyeballing” method that will equip you to answer most of the likely questions on this topic in the PMP exam. This second video will allow you to answer questions involving Early/Late Start/Finish through the use of the forward/backward pass technique.

    Thanks for the feedback! There is always a chance that you may need to calculate ES, LS, EF, LF. In this Part 2 Video we calculated ES and LS, the Earliest each task can Start, and the Latest each task can Start without extending the project duration. To calculate EF or LF, simply add the task duration to ES or LS, i.e. EF = ES + Task Duration, and LF = LS + Task Duration. I hope this helps.

    Sir Ganttalot – good video. You should have taken the monicker Sir IknowALot :(

    BTW, where does the LATE Start/Late Finish come into the picture? Are they comparable to Early Start/Early Finish and would we be asked to calculate LS/LF on PMP exam?

    Part 2 response: …
    Part 2 response: You may have seen in Microsoft Project, Leads and Lags in the Network Diagram don’t show up as ANYTHING other than adjustments to ES and LS. So basically to calculate ES and LS in a lead/lag situation you can do what MS Project does, i.e. modify the predecessor duration by adding time for lags, subtracting time for leads. That way the formulas mentioned in the video should work. Try it out in a simple situation with 4-5 activities to see what approach works best for you.

  13. SirGanttalot Says:

    Part 1 response: To …
    Part 1 response: To draw lags you could replace the lag with an activity actually named “Lag”, or use a real name such as “Wait for paint to dry”. Alternatively you could add the words “Lag +3 days” for example above the arrow connecting the two tasks. To draw leads, you could either show the connector arrow as a line that turns back underneath itself before turning to go forward again and also label it as “Lead -3 days”, or leave it as normal connector but still label it as just described.

    How do you draw a diagram showing tasks with a lead or lag time and then calculate the ES or LS?

    Sir Ganttalot, I have attended PM classes in the undergrad life, in work life and in PG studies, in class rooms and distant learning. I have never experienced an explanation with this clarity. You are definitely gifted.

    In summary, 5 Star work and I look forward to learning a lot from you.
