When purpose is unclear, teams can optimise locally, produce work nobody needs, and deliver an inconsistent client experience.
Decisions escalate because people lack a common understanding of organisation priorities (e.g., customer reliability versus resource utilisation).
The result is Muda (rework, reports no one reads), Mura (uneven service), and Muri (overburden).
Without an appropriate vision, a transformation effort can easily dissolve into… confusing, incompatible projects
John P. Kotter, Leading Change
Overproduction is often the biggest waste: making more, earlier, or with more features than the customer needs.
It looks productive yet builds WIP, hides defects, and lengthens lead time.
Avoid it by switching from push to pull, capping WIP, sizing work to takt time (available time ÷ demand), and setting clear entry/exit criteria for each step.
Of all the wastes, overproduction is the worst
Taiichi Ohno, Toyota Production System
When purpose is clear, people can take the right initiative.
Make problems visible, create psychological safety to raise them early, and coach people to run small experiments.
Leaders model “go see, ask why, show respect,” recognise purpose-aligned initiatives, and remove blockers quickly.
Ownership then becomes normal, not exceptional.
Try to catch people in, don't try to catch them out
