Depending on the level of analysis, you can manage tasks as checklist items or cards.
For example, a portfolio manager might need an overview of all the projects that are planned, which may contain thousands of tasks. It would be unfeasible to create a card for each of them in this case. So she add a card for each project, and tasks as checklist items.
On the other hand, the project manager might want to add details to a task (such as descriptions, attachments, comments, etc.). This not possible with items, so the option is to create a project board and add cards in it.
But if they want to have both, they can use Placker to mirror items into cards. That is, tasks will be items at the Portfolio board and cards at the Project board at the same time.
Plus, they will be synced, to if the Project manager marks a card as complete, the Portfolio board will also be updated reducing the need of sending a message to say that it's done.
Placker dashboards and reports are generated at a card level, so this also helps in those cases.
You can set this up in your boards following three different methods:
At placker.com, select both boards.
Click the checklist icon at the project card, then click and drag an item or the whole checklist into a list in another board.
In this case, item A.1 is being dragged to the "To do".
Select if you want to also show the card title and confirm changes.
Now the item is mirrored as a card. Changes in the card (e.g. marking it as complete) will update the checklist item and vice-versa
The other way around also works (taking a card and dragging it into a checklist)
Rule based mirroring
If you need to mirror many items, it might be a good idea to create a rule to do this in an automated way.
At placker.com, click the title of the board where the items are
At the "Rules" tab, create a new rule selecting the "Member is assigned to checklist item" option.
You can also decide what happens when you unassign a member from the checklist item
Now, when you add a member to a checklist item, Placker will automatically mirror the checklist item
You can also use the Card Mirror by Placker power-up to create rules and assign members to checklist items in Trello (you might need a paid Trello subscription to do this there).
It's also possible to import a spreadsheet containing information from the card to be mirrored.
This works for card to card, item to card and card to item mirroring. Learn how to do this in this article,
