Systematic problem solving is one of the key capabilities your Team should have to enable improvement in the first place.
A3 is a lean management-tool that will help you solve problems. The A3 report is a document in which you can display a whole process in seven steps on one single page.
It is based on the PDCA-Cycle. Whereas the left-hand side of the document displays the Plan, the three other stages (Do, Check, Act) can be prepared on the right-hand side.
Through close collaboration on every step from problem definition to concrete results, combined with an active knowledge exchange, your team will be able to get down to the root of every trouble. While discussing on every step of the process, the A3 report reflects all results and allows you to present a consistent report, propose enhancements, or use it for other fertile purposes.
As the A3 method involves the whole team to deal with the issue, it empowers your people to independently solve problems. This does not only release you as a leader, but also qualifies your colleagues to cope with more and more complex tasks.
