Is it possible to apply LEAN thinking and it's principles in a collaborative environment where your team is overlapping stages in order to reduce the time to market. I know that in KANBAN you have stage gates inside your process, which allow you to define WIP limits and measure cycle times which as I understand allows you to improve your process.
But what about the scenario where you are, instead of waiting until the previous process step is complete and then pulling the item, you are working collaboratively and as a result you do just enough work so that the next person in the next column can start working on the same item whilst you, in the previous column, can carry on finishing your work on the same item.
So in a nutshell you are working more collaboratively and overlapping the work between neighbouring columns to reduce time to market. In such a scenario is it possible to :
a) apply LEAN thinking and it's principles, like Little's Law together with all it's assumptions.
b) measure cycle times even though you are overlapping work.
c) be able to use the data obtained from Cycle Times and Lead Times to analyse the data by way of Scatterplots and Cumulative Flow Diagrams.
I would be really grateful if someone can shed some light on this.
