Implementing Lean Culture? Somewhere Between ‘Next Week’ and ‘Next Decade’

Too many companies treat change like flipping a switch:

“We introduced a new system. Why aren't people using it yet?”

Because change isn’t software. It’s people.

People resist change for three main reasons:

1. They don’t understand it. (Hello, poor communication.)
2. They don’t see the benefit. (What’s in it for me?)
3. They weren’t involved. (It happened to them, not with them.)

So the real timeline for change? 👉 It starts before the first workshop. 👉 It continues after the last slide in the PowerPoint.

⏳ A Realistic Timeline

Let’s say you want to roll out a process improvement initiative

1) Awareness & buy-in | 2–6 weeks | Get leaders aligned first. Resistance loves silence.

2) Diagnosis & current state mapping | 4–8 weeks | Don't skip this. Fixing symptoms ≠ solving problems.

3) Pilot implementation | 6–12 weeks | Pick one area. Fail safely. Learn fast.

4) Full rollout | 3–12 months | Scale only what works. Adjust what doesn’t.

5) Culture embedding | Ongoing | Habits take time. Culture takes even longer.

 So yes — you can start seeing results in weeks. But lasting, sustainable change? We're talking months — or even years — depending on company size, culture, and leadership will.

 🚀 Speeding Up Change Without Breaking People

Want to move faster? Here’s what actually works:

✅ Involve people early — especially skeptics.

✅ Communicate simply, often, and with purpose.

✅ Celebrate small wins. They’re the building blocks of momentum.

✅ Make change visible — boards, KPIs, dashboards.

✅ And most importantly: walk the talk. No one follows a leader who only points.
