A spreadsheet can tell you that rejection increased. It cannot show you the exact hand movement, delay, temperature excursion or unclear instruction that caused it. GEMBA starts by going to the real workplace and observing the work as it is actually performed.
For horticultural packhouses, the approach connects management decisions directly to grading, packing, hygiene, cold-chain and dispatch activities.
Start with a clear purpose
A GEMBA walk should focus on a defined question: for example, why customer complaints increased, why rejects are rising or why a critical hygiene step is inconsistently completed.
Observe before offering solutions
- Watch the process against the agreed work standard
- Ask operators what makes the task difficult
- Look for delays, rework, waste and abnormal conditions
- Record facts instead of relying on assumptions
Use visual management
Current targets, defects, temperatures, sanitation status and open corrective actions should be visible to the team. Visual controls shorten the time between a deviation and a response.
Respect the people doing the work
GEMBA is not a fault-finding exercise. The people closest to the process often understand its constraints best. Supervisors should ask, listen and remove barriers rather than use the walk to assign blame.
Close the loop
Every important finding needs an owner, due date and verification. Review recurring themes in management meetings so repeated observations become system improvements rather than isolated fixes.
