Great improvement begins with a concise, customer-focussed problem statement.
Define the gap from standard with evidence, the affected customer, and the impact and avoid jumping to any solutions.
Keep the ‘charter’ to one page and share with stakeholders so that decisions, experiments and evaluation stay aligned to purpose.
The aim of the A3 is not the document; it is the process of thinking and alignment
John Shook, Managing to Learn
Write a problem statement. Agree one success metric and owner. Share a 'charter' with the team. Brainstorm. Run one experiment today
Standard Work is the best known way today to meet customer demand with safety, quality and flow.
Make it visual and accessible (one-point lessons, checklists, screenshots, videos).
Where appropriate, define TAKT time (the rate of customer demand), work sequence, standard WIP, Process time.
When a better way is proven with small experiments, update the standard the same day!


Standardisation is the foundation for Kaizen

Teach with TWI Job Instruction (Prepare → Present → Try-out → Follow-up).
Coach using ask-first questions at the Gemba.
Share and celebrate learning updates to standard work.
