Dependencies - more options

It would be very useful if there would be dependencies like End-End or Start-Start, not only End-Start.

        100% agree - is the biggest missing feature I've encountered so far.

        This would be awesome! +1! But it looks like it's been a very long time since this was suggested

        Anybody out there? Please implement the common PM dependencies as well as a lag function

        +1 for start-start dependencies

        I agree with all the comments below. This is the biggest hole I see with the TG product. All the different dependency options are critical, along with multiple dependencies assigned to a task, and the ability to assign float.

        The functionality of this software is the very best that I have seen (drag and drop), but these items being missing makes the tool only marginally effective. The lack of these features will keep a lot of professional PMs from using this tool- which is a shame.

        Totally agree this should be extended as soon as possible. Personally I need to be able to state that task A must be completed x days before task B is completed.

        I agree with all the comments. I don't often use the other types of dependencies, but they are helpful to have. Having some of the other features people have mentioned would also be helpful, but there are workarounds for those.

        I totally agree with Suzanne and Ryan. SS, FF, SF, FS with buffer either in absolute values (e. g. days) or percentage. For example a task can not start before the other one has 50% progressed. Or two days before one task is finished the other one must start.
        Also multiple constraints are important because more than one task can depend on one other.

        Definitely something that I was looking for, its very irritating when you have to manually update several tasks in several projects every time you have a delay, its even worse if you are finished earlier with a task...

        Please add this :)

        I agree -- this is critical for real world management. End-Start dependencies reflect a pure waterfall methodology. But the reality is projects are much messier, where a dependent task doesn't wait for its antecedent to complete.

        So for example, task B will often start when Task A is only 75% complete. Yet there is still a dependency between these tasks such that if task A gets postponed by a week so does Task B.

        This is so important that a gantt chart MUST support this to accurately reflect the project. Otherwise users have to trick the software by either eliminating explicit dependencies all
        together, or entering incorrect start date for many tasks.

        Multiple dependencies is also critical in order for a gantt chart to accurately reflect reality.

        In my experience these are not just nice-to-have features, they are absolutely essential to any gantt chart tool.

        Another good dependency option would be a set number of days before or after. For example: Task B can't start until 2 days after Task A.

      • SuzanneSuzanne commented  · 

        I would add to this what I would call multiple dependencies i.e. these three things all need to happen before this other thing can happen, so three dependency lines all go to the same task or milestone.
