Base WIP Limits on Card Size

LeanKit's step-by-step guide on how to base WIP on card size and understanding the effect card size has on WIP. 

Since card size helps to identify the estimated effort of work, basing WIP on card size helps to identify when the estimated effort associated with work in process overloads the system.

To base WIP limits on card size for a board, click the gear icon in the upper right of the window. Next, click Board Settings from the drop-down menu. You will be on the Board Settings tab. Check the box next to “Base WIP Limits on Card Size.”

WIP limits can be established for lanes, including sublanes and swimlanes, and for board users. To learn more about how to setup WIP limits, read here.

Once WIP limits are established and the setting to “Base WIP Limits on Card Size” is in place, the WIP limit warnings and override events will be calculated on card size rather than the number of cards.

Here’s an example of standard WIP setup. The lane WIP limit is set to 3 and is based on number of cards. When there are 2 cards (with a combined card size of 4) there is no WIP limit warning or override.

Once a third and fourth card are pulled into the lane (with the standard WIP setup), the system requires a WIP limit override and the lane, along with the WIP limit number, stays red until the WIP limit of 3 cards is once again observed.

In this example, the lane WIP limit of 3 is based upon card size. The 2 cards in the lane have a combined card size of 4, which is over the established WIP limit of 3 (and requires a WIP limit override).

This same logic is applied to board user WIP limits. If the setting to “Base WIP Limits on Card Size” is not selected, then the user WIP limit is based upon the number of cards assigned to the user. If the setting to “Base WIP Limits on Card Size” is selected, then the WIP limit warnings and overrides take the total card size assigned to the user into account.
