Why Size Doesn’t Matter

This presentation is probably not about what you think it is about.  Rather, in this session I want to dispel one of the most popular myths about what is required when limiting Work In Progress (WIP).  I cannot tell you how many times I have heard the statement, “Our team can’t limit Work In Progress, because limiting WIP requires all work items to be of the same size.”

Nothing could be further from the truth.  Not only is getting all items to be the same size not necessary to achieve flow, but, in many contexts, trying to similarly size work items is at best a premature optimization and at worst an unnecessary one.  Most often, differently sized items are not the variability that is killing your predictability.

This session will discuss some reasons why work item size does not matter when limiting WIP and will introduce some more fruitful improvements to focus on when addressing the very real problems of variability and predictability.
