I'm at a client site this week, delivering a series of "First Steps with Lean Product Development" workshops for engineers. This workshop provides a basic introduction to the concepts of Lean Product Development and then does a deep dive into the LAMDA cycle and A3 reports. Each participant writes an A3 report over the course of the day.
In the workshops, participants use blank sheets of 11 x 17 paper and pencils to create their first A3 reports. I never write A3 reports in this manner, and I don't expect anyone to make more than one this way. However, I have found that both my client companies and the course participants benefit from one guided experience with a blank page.
Doing it this way counteracts two of the major tendencies that new A3 adopters tend to have which diminish their potential benefit: They want to create / use a template, and they want to fill it all out before they show it to anyone.
First, A3 is just a paper size. There are some good reasons for using 11 x 17 or A3 paper to produce a concise report. It has a good amount of space but one can see the entire page at a glance. It is large enough for good visual models but small enough to force conciseness and focus. It hangs nicely on walls and fits well into standard binders. Letter sized paper (8.5" x 11" in the U.S.) is just too small while anything larger would be cumbersome. But nothing about the paper size dictates the format. A "good" A3 report contains the information needed to help the author accomplish the purpose - and nothing extra.
The contents of the report can - and should - be at the entire discretion of the author. When I teach these reports, I emphasize that only three things are really required: a title, the author's name and contact information, and a one-sentence summary of the problem so that I can quickly decide whether or not I need to read the entire thing. I have expressly forbid some clients from creating any sort of A3 "template" for at least six months after they begin using them, because I know that if they did create a template, all the A3s would look exactly the same, and the format would become just another report that someone has to fill out, rather than a working problem-solving tool.
Over time, the visual models, tables, lay-outs and structures that work well tend to become more prevalent, and experiments that fail die out. The organization develops a look-and-feel for the reports that matches their use inside the organization. There may eventually be standard templates for some things, like status reports but probably only loose guidelines for others. Peer feedback with some coaching and mentoring from senior team members accomplish the rest.
The other problem with templates is that people want to fill them out completely and perfectly before showing them to anyone, especially managers. But A3 reports work best when they are working documents and when the author begins to get feedback almost from the moment he or she puts the title on the page. "How do you see this problem?" is a good question to ask at this point. Hand sketches, scribbled edits and notes are all fair game and empty boxes tend to solicit both better feedback and buy-in from the reviewer.
How are you using A3 reports in your organization? How much diversity do you have in the format and appearance of these reports? When do you begin showing them around and how perfect do they need to be before they make their public debut?
