There is no greater tool in Lean than the A3 report. I use it often and find it hugely helpful in getting everyone on the same page (literally). The A3 reports are in Word. In this product you can find three types of reports:
- Defining the problem
- Progress report
- Project end report
To use the A3 you need to be well acquainted with scientific thinking (PDCAPDCA and Have you learned about kata in your lean certification?). You also need to be able to influence your stakeholders and first and foremost to go and see for yourself..
In my appreciative lean tools you can also find an appreciative A3.
