Blocker Clustering, LKCE14

Herunterladen, um offline zu lesen

A central component of Kanban is to make invisible knowledge work visible. However, you will notice quite often that you very often cannot work, but are blocked. Waiting for the test environment, requirements unclear, or missing customer information are only a small part of blockages that prevent us from continuing to work. These blockages are in most cases not a singular event, but have a systemic cause. In other words, it is very unlikely that a blockage occurs only once in the history of a company. Normally the same blockage occurs again and again.

What can one do about it? Jumping out of the window in despair would be a possible approach. Another idea would be to see the blockages for what they are: Treasures of improvements. In this session, we show you how to harvest these treasures and to improve sustainably your working system. In addition, we will present a model that shows with the help of a few simple number games, which blockages need to be removed to achieve the greatest possible leverage.
