Unpredictable tasks and resource allocation RRS feed

  • Question

  • I have 5 tasks which I want to spread over various

    Design review
    Business meeting scrum
    Branching
    Configurations


    Callback functions

    1. Design the function  - 2 hrs
    2. Call the data format function  - 3 hrs
    3. Callback function with data format  -2 hrs
    4. Enable the test flag -0.5 hrs
    5. Execute the test with test data - 8 hrs

    1. Why is that resource allocated comes out overloaded when I am sure the resource allocated is not spending more than 8 hours per day.

    2. Please advice how to represent the effort vs time when the effort is unpredictable like say, task 5 is run every time task 2 and task 3 are initiated. But they are unpredictable ..

    3. Task 5 is spread over 2 days (unpredicatable)

    Please Advice

  • Anand,

    With regard to resource overallocation, first take a look at your leveling options under Resource/Level group/Leveling options. Is it set for day by day or is it set for a tighter allocation (e.g. hour by hour or minute by minute)? Normally you should have it set for day by day or week by week. If it is set for day by day, take a look at the Resource Usage view and look at all the timescaled work for the resource in question. Even though that resource may not be overallocated on a current task, if he/she is overallocated on some future task, then you will get an overallocation indicator.

    With regard to unpredictable tasking, Project does not operate with fuzzy logic. Everything must be defined as absolute. If task 5 must run either concurrently or immediately after tasks 2 and 3 then those tasks should be linked start-to-start or finish-to-start. One thing you can do to accommodate tasks that may occur at any time during a certain period is to set them up as fixed duration. For example, let's say that tasks 2,3 & 5 will occur sometime during the week but the exact start is unknown. Set them up as fixed duration, assign the resource and work hours. Project will spread the work linearly over the full 5 day duration. When you determine the actual start, enter that date into the Actual Start field. You can then also adjust the work hours per day as needed.

    Another method would be to set up the tasks as fixed work and link them as required. Set the first task up with an estimated start date. When you determine the actual start date, enter that in the Actual Start field. Project will then shift the schedule to reflect what you expect to happen.
