Common Pitfalls

By The SimplicityHub Team

Most continuous improvement programmes don't die in a dramatic failure. They fade — the weekly huddle gets skipped, the tracker stops being updated, the champion moves to another project, and six months later nobody can quite explain what happened to "that Lean thing we were doing." Here are the five patterns behind that fade, and the practical fix for each.

1. No one owns the Control phase

Teams pour effort into Define, Measure, Analyse and Improve, then treat Control as an afterthought — a control chart nobody checks, a SOP nobody re-reads. Without a named owner and a scheduled review cadence, gains erode within weeks. Fix: assign a specific person and a specific recurring check-in (weekly for the first month, then monthly) before you consider the project closed.

2. The problem statement was too vague

"Improve customer satisfaction" or "reduce waste" isn't a project, it's a mission statement. Vague problem statements lead to vague data collection, which leads to a team arguing about opinions instead of testing causes. Fix: a good problem statement names the specific metric, the specific gap, and the specific timeframe — e.g. "Late deliveries on the Tuesday route have risen from 4% to 17% since March."

3. Leadership backed the launch, not the follow-through

It's common for a CI initiative to get a strong kickoff — a launch meeting, a banner, a mention in the all-hands — and then silence from leadership once the initial excitement fades. Teams read that silence correctly: this isn't actually a priority. Fix: leadership needs to ask about the project's metrics in normal operational reviews, not just at the launch, so the signal that it matters doesn't disappear after week one.

4. The fix wasn't tested before it was rolled out

Skipping a pilot and rolling a change out to the whole operation at once is a common shortcut under time pressure — and it's how unintended side effects get discovered at full scale instead of in a controlled trial. Fix: even a short pilot (one shift, one line, one week) surfaces problems while they're still cheap to fix.

5. There was no visible link between the project and a business result

If the only people who know a CI project happened are the ones who ran it, it dies with the next reorg. Projects that survive are the ones tied to a number leadership already cares about — cost, throughput, on-time delivery, complaint rate — and reported back in those terms. Fix: translate the improvement into the language of the P&L or the KPI dashboard the business already watches, not just process-improvement jargon.

The pattern underneath all five

Each of these comes back to the same root cause: treating DMAIC as a one-off event instead of an operating discipline. The Define, Measure and Analyse phases get the attention because they're interesting; Control gets skipped because it's less exciting and looks like admin. It isn't — it's the phase that decides whether everything before it was worth doing.

Our free DMAIC templates include a proper Control Plan and Sustainability Plan template, built specifically to stop projects fading once the initial win is banked.
