As our knowledge and practice of Lean has developed, many of us have come to the conclusion that there is no standardised “one size fits all” roadmap or sequence that details every step of “how to implement Lean” for every organisation. But there are three vital stages that it makes sense to follow. Here they are:
1. Grasp the Current Situation. A full understanding – by all team members – of the current situation, is the essential starting point for any improvement activity. Questions to ask might include: Exactly where are we now? What are we trying to do here? What is our purpose, our mission? How do we add value for our customers? Honestly, how are we performing now? Are our measurement systems capable of telling us? Are we collecting (only) the right information to help us to make decisions and to take action?
2. Achieve Stability. What are the most important processes in your business? How do you develop new products or services? How do you deliver them? How do you plan, execute and measure the vital few? How do you manage your people, from cradle to grave? Are these processes capable, under control and stable? How do you sustain “One Best Way”: do you provide clear instruction, effective training, regular monitoring, wide-spread mistake-proofing?
3. Implement Lean. Only now can you begin to change the way you work, with a real prospect of success and sustained improvement. Once you have stable, repeatable processes you can analyse them and find ways to do them better. With the right tools and support the team can simplify and streamline the processes so that you become more efficient and more productive, and achieve better outcomes.
The detail of how to do it – and the exact tools to use – are gained only through years of experience. If you don’t yet have that experience you’ll need to hire it in, but make sure that you coach your people so that they “learn by doing”. By following this approach, and by rigorously following the PDCA Improvement Cycle (Plan-Do-Check-Act), you can genuinely transform your organisation and make Continuous Improvement a way of life.
