how to make a limit for the tasks in 1 staus

[AB 1]

For example, we have the status "To do" and we want that there would no more than 3 tasks at one time in this status - so we want to make a limit for them. How can we make it?

Hi @AB 1 -- Welcome to the Atlassian Community!

Blocking a thing like WIP count with JIRA may lead to unintended consequences: like people doing work that is not on your Kanban board...especially expedited work items.

@John Funk and @Pramodh described how to visualize the WIP contraint on the board. 

Next consider a pause to discuss with the team why and when the WIP limit applies.  When someone wants to pull more work, the team asks them to answer:

• Have I finished and met the exit policy (definition of done for a status) of what I am working on now?
• Have I checked my work, ensuring I do not create errors downstream of me?
• Could I help others finish work they are doing?
• What could I do to improve my work methods?
• And only after those, consider pulling in more work

Best regards,

Bill

Hi @AB 1  - Welcome to the Atlassian Community!

The normal Kanban way to do this is to set a WIP Limit on the column. You can do that by going to Board Settings > Columns and changing the Max value for the column. 

That won't prevent cards from entering the column, but the entire column will light up rRed when the limit is broken.

Hi @AB 1 

If you are running an active sprint, you have the option to set the column constraint in board settings
