Stop Improving the Wrong Problem | VOC Interviews in Lean Management
Many improvement projects fail before the first action is taken.
Not because people do not care.
Not because the team is lazy.
Not because the tool is wrong.
They fail because the business starts improving the wrong problem.
A KPI can show what happened.
A complaint can show where pain exists.
But neither always explains what the customer, team or process user actually experienced.
That is where VOC interviews help.
In Lean Management, value should be defined from the customer’s perspective before we redesign, standardise or improve the process.
And the “customer” is not always the external buyer.
It could be:
Production.
Warehouse.
Planning.
Customer service.
Suppliers.
Managers.
Employees.
VOC interviews help reveal the context behind the problem:
What is frustrating people?
What is slowing them down?
Where do delays, errors or rework happen?
What information is missing?
What does success actually look like?
The lesson is simple:
Do not improve from assumption.
Ask.
Listen.
Clarify.
Improve.
Validate.
Lean starts with value.
Value starts with listening.
Improvement starts when we stop guessing.
