Critical path and linked dates

[Emma Tysvaer]

I have added all my project activities to my trello board and have the dependencies identified within required cards. Is there a power up that will update the dates where dependencies have been identified on applicable cards?   As currently if a date is missed i have to go into each dependent card and update the dates individually.

As far as I know, there is none. See my post of Jan 14

yes i am after exactly the same as you.  we have lots of cards in a board that have dependencies and it is far too time consuming to update each card manually.  I will add to and follow your post, also if I find a way I will let you know.

I modified the code from a custom power up to be used via a http request.

While I have the input parameters on the same board, it can be a card from another board.

The override days can be just a single entry, a series of comma separated entries = or < than number of dependencies, etc

@milynnus  thanks for your response, I am quite new to Trello myself and i'm not sure what this is telling me.  I want a tool that auto updates any dates that are impacted by a card that is delayed, so when i push back the due date it automatically pushes back those dates of the cards that are dependent.

You might want to go through this tutorial

https://help.trello.com/article/1165-task-dependencies

I made a quick video to illustrate the difference between

(1) effecting the same date change on dependent tasks vs

(2) cascade date changes across dependent tasks based on days between tasks

Thanks for this I will look into that - so when subtask 1 moves or is delivered last the subsequent sub tasks are pushed back.  But i am therefore assuming you need 1 card with all dependent tasks listed on the checklist to start off with?

What I have illustrated is a way to cascade the date changes across dependent tasks(2) and how to bump dates ie adjust dates by same amount (1).

It not dynamic and does not automatically adjust downstream dates based on completion of a upstream task. There is no way for the system to dictate how work will actually be performed by the various actors. 

You should be able make to use the due/start due and then invoke the endpoint to compute the new dates.
