Prototyping to learn
The team started by quickly building a prototype wall using index cards with mail-merge stickers on them describing each procurement project. This information had previously lived in a spreadsheet. With the work quickly thrown up onto a wall, they asked themselves the question: “What is this wall not telling me?”.
Answer: a lot! There were so many cards it was hard to see what was going on. They were hard to read. And the wall couldn’t tell the team anything about cycle time: how long was each project taking to go through the whole procurement process?
Additionally, one of the team members had a visual disability, so the team wanted something with high contrast and large lettering. This was going to be hard to achieve with cards, given the number of procurement projects which were in flight at any time.
With this learning, the team built a second board, this time from Lego.
