The 5 Whys Method
The 5 Whys method is part of the Toyota Production System. It was developed by Sakichi Toyoda, and has become an integral part of the Lean philosophy. As my regular viewers know, I am a big fan of raiding Japanese management and production techniques and applying them to strengthen our project management toolkit.
Five Steps for Using the 5 Whys Method
1. Gather your team
Who do you need, to help you solve the problem?
2. Define what the problem is
I cannot over-stress the importance of direct knowledge of the problem – going to the gemba.
3. Find root cause with 5 whys
Ask why the problem happens and record the answer.
If the answer you just got doesn’t identify the root cause of the problem, ask ‘Why’ again and write that answer down.
Keep going until the team agrees that they have found the problem’s root cause. This may take fewer or more than five Whys.
Here’s the problem. The roll-out of new laptops to the Southern region is running a long way behind schedule.
Why? We planned for 45 a day – the average rate is only 22 per day
Why? we expected 5 full-time technicians from the Southern IT ops team to join the project and we have 2 full-time and two part-time
Why? The regional IT manager has other priorities, so she keeps diverting resources
Why? She is unaware that the Main Board considers this a mission-critical project
Why? She was on holiday at the IT Manager’s meeting where the CEO made this clear
There is nothing special about five. It often gets you to the right place, but always keep going until you self-evidently have reached the root cause.
4. Develop a solution
Now the solution is clear. We need someone very senior – her IT Director boss or maybe even the CEO to speak with the Southern region IT manager, to secure resources to catch up and deliver on time.
5. Take action to implement the solution
There is no change without action.

What Kit does a Project Manager Need?
I asked Project Managers in a couple of forums what material things you need to have, to do your job as a Project Manager. They responded magnificently. I compiled their answers into a Kit list. I added my own.
