Support effort-driven scheduling #83

In effort-driven scheduling a length of a task depends on the amount of 
required work (in man-days or man-hours) and availability of resources. 

The basic rules is:
* If a task requires 3 man-days and a person who is doing this task is 50% 
available then the task must become 6 days long.

I agree with the comments added to the previous issues of this one 
(http://sourceforge.net/tracker/index.php?func=detail&aid=1186184&group_id=72728
&atid=535430).
I'm evaluating Ganttproject for my team and this is a killer criteria. I've two 
contractors working only 60% and 4 developer working 80% for this project.

I was also evaluating this tool, and am really missing this feature. I used to 
work with Twiddlebit Plan For Windows on my previous job, where we use this 
continuously. Tracking progress and/or validating estimated workload is very 
hard without this.

Same thing for me. I am very surprised this feature has not implemented yet. 
Unthinkable to work with a project management tool without.

This feature would be very helpful and save large amounts of time when trying 
to get close to a realistic schedule

Hello,

I also found this error a few months. The consequence is impossibility for me 
to use GanttProject ... what a shame.
It is essential that the end date of a task assigned to a partially missing 
resource is calculated correctly otherwise the project planning is distorted.
I hoped that version 2.6.2 include a patch ...
When this subject will be corrected ?

Thanking you.

Regards.
Kriss

Please support this feaure. I too require it, it's the mainstay of project 
plans which reflect real world workloads and would rather not look elsewhere, 
everything else on Ganttproject is near perfect.

I was just looking at switching to the gantt software but without effort driven 
scheduling and duration in hours it is practically worthless to me. please let 
me know if this has been added or will in the future because I like everything 
else so far. Thanks

Do you have any idea when this will be implemented? I keep getting back to your 
software, but this issue keeps killing my use of it.

You probably know that GanttProject is developed in spare time. All promises or 
estimates about when something will be implemented are wrong by definition, 
that's why you don't see any of them.

I agree with the others...I was really loving this program until I hit the wall. No resource leveling at all? No effort driven task length? For me this went immediately from "best program ever!" to worthless.

joacimsvensson commented Dec 22, 2016

Agreed. No resource leveling and effort-driven scheduling kind of defeats the purpose of Ganttproject as a project MANAGEMENT tool.

I feels like something that should be a core functionality in any project management software. You have resources with allocated time, you have tasks - surely they should interact.

Just wanted to add another +1 to the request for resource-focused / effort-driven scheduling. It would be a major upgrade

Hello,

I was looking for an alternative to MS Project, and I was very entusiastic with GanttProject, until I reach this issue.

From my point of view, to manage a project based in tasks,, I need the tasks to be affected by the number of ressources working on it, and their availabilty.

If a task as a duration of 10 days, and I assigned 2 ressources to it, I need that this task is reduced to 5 days.
And if I assigned only 1 ressources with a 50% dedication, the duration of the task should be of 20 days.

This features is a deal breaker, and it has not to be linked with the issue of the day-offs.

Hoping this issue would be take in account shortly.

Hello,

  • 1 for me. It was useful until I read this. Everyone defines tasks as effort-based non day-based. This is a major issue.

Even if a partial implementation of effort-driven scheduling would be great. For example, a resource have a certain limit of parallel tasks he can realistic work on it. Right now you can assign as many tasks as you want to a resource and they will all run in parallel. In my experience this really broke my use case for using GanttProject.

I am interested in contributing to this feature but it would be nice if I could get the following info from the devs/mantainers:

  • Which source files are related to the options the user can modify via the Task property window?
  • Where is the task duration calculated? I saw something here but I am not sure.

+1 This issue has been ongoing since 2017 (5 years now). I think this is a major feature and should be priority task...
