Hello Steven,

thanks for your post.
Unfortunately, this feature is not yet implemented in OpenProject.
But there is a feature request which seems to be similar to what you describe: .

For the future it is planned to improve the timeline (not yet scheduled). This may very well be a useful feature.

As a work around you may want to take a look at the Task Connector for MS Project:
https://community.openproject.org/projects/task-connector?jump=timelines
This plugin for MS Project provides an easier way to create / update timelines in OpenProject.

Best regards,
Robin

Hi Robin,

Thanks for the reply. Unfortunately, we don’t have at my current company licenses for MS Project, plus I’m on Mac ;)

So that isn’t really an option. Looking at the code, it seems to be done in one function. I’m a developer, but never used Ruby, but it doesn’t seem like it would be too difficult to hack together something that moves things backwards when “follows” is present, I’ll try my hand at doing it, and put up a PR. But the UI stuff, I don’t think I would be able to do!

Plus, to do it properly, you would need a new field in the DB to indicate the desired behavior (I don’t know if everyone wishes to have follows mean that the start date is linked to latest end date of precedents). In addition, I really would like to have a way to specify end date using start date + duration, as that is a more natural way to estimate task times.

I did see the user story you refer to, which would be equivalent to my hack, but my request is slightly more complex than yours. I wanted to first ask on the forums as I’m new to the software/community before filing a competing feature request.

We are also interested in this kind of functionality.

Having the due date been computed from estimated hours (probably only if due date is less than the one computed from estimated) would help a lot to schedule the project. Also having a way reschedule when a date is moved backwards would also be great.

I’m looking myself to have a first try (my fist attempt at ruby) modifying “scheduling_rules.rb” but found another problem, that openproject doesn’t have any information about working days and weekends. There is anyway to have this in consideration or am I missing something?

I too would be very interested in features like this.

Previously, I have been using a simple list (read: Excel!) of Tasks for a project with estimates (in hrs), which gave me an overall estimate of when all of the remaining tasks would be complete. While this (just about) worked, it was only good for managing work and estimating for ONE person/resource.

I was hoping to use OpenProject to allow me to:

1. Have a list of tasks/work packages for a given Project release/version
2. The Tasks will be worked on sequentially
3. Ordering (and re-ordering) of Tasks should be determined by priority or manual positioning
4. With work assigned to different people/resources, the overall estimate of when all work will be completed can be auto-calculated
   (e.g. Start Date + total of # estimated hrs remaining across all remaining Tasks, taking into account Holidays, etc.)

Is any of the above do-able/planned? Do I just need to use the software differently? Because Open Project looks really great and I’d like to use it.

There’s no way that I’m gonna be able to (as the OP mentioned) change the Start/End date for ALL tasks on a regular basis as Tasks get re-priorities/completed/etc.

Any guidance would be much appreciated.

Many thanks,

Paul.

Is anyone from OpenProject able to comment on my post above? Thanks.

(apologies to Steven for hi-jacking his thread a bit, but I think it’s on-topic?)

Hello Paul,

you can accomplish several of the objectives you mention via the work package list.

1. Have a list of tasks/work packages for a given Project release/version

You can create versions in OpenProject (Project settings > Versions) (e.g. for project releases).
After creating a version, each work package can be assigned to a version.
Using this you can go to work packages and create a filter “type is [name of version]”.

2. The Tasks will be worked on sequentially

To accomplish this, you can (optionally) add the start and due date to the work package list (via the settings icon and selecting “Columns …”).
Then you can sort by the due date (or start date if you prefer).

3. Ordering (and re-ordering) of Tasks should be determined by priority or manual positioning

Manual positioning is currently not possible via the work package list. If this is essential to you, you should take a look at the backlogs plugin.
However, you can either sort or group by the priority assigned to a work package.
OpenProject offers several sorting levels (access on work package list by clicking on settings icon and selecting “Sort by …”) which are applied one after another (this can be used if you want to sort by date and priority).

4. With work assigned to different people/resources, the overall estimate of when all work will be completed can be auto-calculated
(e.g. Start Date + total of # estimated hrs remaining across all remaining Tasks, taking into account Holidays, etc.)

This is not yet possible. However, you can display sums (e.g. for remaining hours) by selecting “Display sums” from the settings icon in the work package list (make sure the column for which you want to display sums is set to “summable” in the admin settings (Modules > Administration > Settings > Work package tracking)
You can also filter by user(s) (“Assignee is …”) to display only work packages assigned to specific persons (especially useful when using the option “Assignee is ” since every user can immediately see which work packages are assigned to him / her).

After configuring the work package list the way you want, you can save it and also add it to the side menu for quick access.
(Also take a look at the user guide for details.)

Here is an example how this may look like:

Best,
Robin

Thanks for the detailed response Robin, much appreciated.

Item #4 is pretty much essential for me at this point, otherwise that’s several additional calculations that would need to be done manually.
For example: Take project/version start date and ADD the number of remaining hours for Assignee #1, but also factor in the work remaining for Assignee #2 (e.g. two people working through all their items in parallel, perhaps at different work availability %’s)… all to come up with an estimated date when all the work will be completed (taking into consideration non-working days, Assignee holidays, etc.).

Do you know whether this kind of planning/estimation (or similar) is in the pipeline for OpenProject?

Failing that, is this something that (you think) could realistically be done by others (I’m a developer, but mostly Windows/C#, not web) by extending the platform by some kind of plugin? Is this even possible/worth considering?

Thanks again! :)

I created a branch to fix this. I tried to update the feature report, but after filling in the following text, I get the error “Module is not set to one of the allowed values.” Seems like a permission issue.

In any case, here is what I was trying to add to the feature report:

Hello, I have created a branch to enable this. I don’t want to create a PR because pulling it would screw up anyone who doesn’t want this functionality.

I would like to get it in mergeable state. What I have done is:

1. Make the start date of following work packages start at the soonest date they can that obeys the relations.
2. Update the validation to reflect this requirement
3. Changed the ‘disabled’ attribute when editing a work package so editing the start date is not possible when it depends on a prior work package.

I don’t know how to do these things:
1. Set up a configuration option to enable this (should really be opt-in)
2. Set up / change tests.

I’m very new to ruby, but have experience in other languages. But rails seems like a very complex thing to pick up without having done it. Please let me know if this has a chance of being accepted, and what I have to do to make this work.

Note: I’m also not experienced with Agile development methodology, so forgive me if I’m not doing this the right way.

The branch: https://github.com/schveiguy/openproject/tree/feature/15875
