One frequent question when working with Lean is “are we going too fast/too slow”? Changing is always uncomfortable and it is normal to question yourself if things are going as they are supposed to be. Well, speed matters in Lean but, as usual, there is no “right” or “wrong” answer here. Each situation is different and needs different approaches, so what to do? Let’s see the problem from its 2 sides:
- The risks if change goes too slow: people feel that problems are not solved, people feel their work is not bearing fruit, higher probability of rumors, higher probability of “I told you it wouldn’t work” and other similar sentences. In summary, Lean loses momentum and looks like “the improvement initiative of the month”
- The risks if change goes too fast: people feel that things are changed with too little analysis, risk looks is higher, there is a higher feeling on improvisation, the valuable ideas of those who don’t speak up easily (introverts, new employees…) may be lost. In summary, Lean looks like something imposed from top management.
Yes, practicing Lean might be complicated. My proposal is to move “as fast as possible”. Start slowly to make sure a) everybody is on board and b) the first “projects” are a success. Then increase speed incrementally. When everybody has been exposed to the cultural part of Lean (we all know people will be respected, lay-offs will be the last option, speaking up is safe…), it is better to go a little bit too fast than a little bit too slow because speed will help create quicker PDCA cycles and learning happens (obviously) also quicker. Change will be evident and everybody will feel it. Always get people’s feedback: the sweet spot is where people feel challenged without being scared.
Lean is like riding a bike: moving either too slow or too fast will make you hit the ground. Start slowly and increase risk and speed as you gain experience.
