manually scheduled tasks RRS feed

  • Question

  • I have created a project with all manually scheduled tasks. Summary and Project summary have by default come as automatically scheduled. There are no constraints to activities.

    • If I change Project start date from Project information box or even through Move project dialogue box the project doesn't move ahead, which in my view logically it should. 
    • Also, If I change the calendar for an activity from 5 days working to 6 days working bar is shown as per the new calendar, but finish date remains same and for the difference in time the bar has a split.
    There is no change in the schedule with these changes even I click on Calculate project.

    How do I see the effect of these changes and what is the function of calculate project.

  • Hi,

    Manually scheduled means Project will NOT change the dates you give in.

    Turn the calculation mode for all tasks to automatically scheduled and most of you want will happen.

    You can't tell Project not to calculate and then expect it does :-)

    Greetings,

    I can confirm everything you see in Microsoft Project 2010 regarding the behavior of Manually Scheduled tasks.  In fact, everything you see is the default behavior of Manually Scheduled tasks.  My question for you is, “Why are you using Manually Scheduled tasks in the first place?”  Everything you expect from the tool would happen if you used Auto Scheduled tasks instead of Manually Scheduled tasks.  Specifically, if you used Auto Scheduled tasks:
    • All of the tasks would move automatically when you changed the Start date of the project in the Project Information dialog.
    • Applying a Task calendar with a 6-day work week to a task would cause the software to schedule the task correctly.
    • Clicking the Calculate Project button would cause the software to recalculate the project schedule automatically.
    From the description of your anticipated behavior for Microsoft Project 2010, I would recommend you change all tasks to Auto Scheduled.  Hope this helps.

  • Dale,

    Thanks for the response. 

    We have similar feature in Primavera, in which by default all the activities are manually scheduled. But, if we make a change like changing calendar or changing the project start date and then schedule, all the activities get updated as per the changed information and it seems logical. This helps in doing step by step what if analysis.

    I was wondering if MSP has similar functionality, because otherwise I do not see much benefit of manually scheduled tasks.

    Please let me know your views on this.

  • Vanita,

    I don't know Primavera or the details of their nomeclature, but in Microsoft Project when you do manual scheduling, you are telling Project "I am hard-coding the project dates and constraints.  Please do not change anything."  So it doesn't. It's just as Jan and Dale says.

    And yes, there is not much benefit to "manually scheduled tasks" and my general rule is to never do it.  I'd prefer Project to do the hard work.  I flippantly sometimes call manual scheduling as "planning by pictures."

  • Well said, Rob!  I am not much of a fan of Manually Scheduled tasks, for the same reasons you state.  My personal best practice use for Manually Scheduled tasks is for unscheduled tasks.  But that’s about it.  Thanks for sharing!

    In regard to Manually Scheduled tasks, Microsoft Project does not work like Primavera.  Sorry.
