Fear of harming In the regulatory-constraint industries like food, chemical or pharma, people on shopfloor are trained and … Continue reading When enough is… enough


What data for changeover monitoring and improvement?

Maximizing the exploitation of critical Capacity Constraint Resources (CCRs), so called bottlenecks, is crucial for maximizing revenue. Changeovers usually have a significant impact on productive capacity, reducing it with every new change made on those resources that already have too few of it.

Theory of Constraints, Lean and aviation MRO

In a previous post, “CCPM helps shorten aircrafts MRO”, I explained the benefits of Critical Chain Project Management (CCPM) for reducing the aircraft downtime during their mandatory and scheduled MRO. If CCPM is great and helps a lot meeting the challenge, it will not squeeze out every potential improvement, thus time reduction, on its own. … Continue reading Theory of Constraints, Lean and aviation MRO

Leader Standard Work

The very first time I heard about “leader standard work” and “scripted day” I was puzzled. Production manager myself at that time, in my view management must be ready for fixing things and react to all the random events that rain down onto a factory shopfloor. How could a day made of fixing unexpected problems be … Continue reading Leader Standard Work
