The idea came from our perception that despite being one of the main buzzwords in the agile community, Lean and its origins are still a mistery to a lot of people, specially now in the current tool age , where kanban means a card wall with some numbers on it.
The workshop aimed at introducing Lean concepts through a hands-on activity, where the participants had to build a simple lego house in this 4 step process.
- Step 1: “Buy” the Lego(TM) pieces and sort them by color
- Step 2: Sort them again by size
- Step 3: Separate the pieces required to build one house
- Step 4: Build the house and sell it
If you are wondering how that turned out in practice, you can check the video here.
In order to go through all the Lean main concepts, the activity was divided in three phases, being the process executed differently in each one: a push system in the first, pull in the second and a single person workcell in the last.
Before every phase, we introduced the concepts that were going to be applied, and after the production, a “retrospective” was held to discuss good and bad points of the process according to the participants.
This way, we could stop and explain the needed concepts between each phase, and were able to go through push vs. pull systems, waste, kanban, kaizen, and work cells, among others.
The feedback we got was very good. All the participants we spoke to later said it was easier to understand what we were talking about when they actually implemented the ideas in practice, and felt the problems that each solution had. What also helped is that most of the participants we’re being introduced to Lean, and this was the exact kind of public we had in mind when we prepared the workshop.
After the activity, a link with software development was made, but always making clear that creating software is not producing cars, so it is much more important to understand the principles then to apply the practices.
