In problem-solving, the key is to dig deeper by asking "Why?" multiple times to uncover the root issue.
Beyond Surface Symptoms
Often, addressing only the initial symptom leads to temporary solutions. For instance, a client sought help for a "slow operator," but through iterative questioning, we revealed a more profound problem:
- Contrary to perception, the operator wasn't slow.
- The real issue stemmed from delayed part deliveries.
- This delay resulted from inadequate staging practices.
- The root cause was a malfunctioning kanban signal.
- Ultimately, a system update, left unvalidated, disrupted the signal alignment.
🔍 The 5 Whys Framework:
- Why is the machine inactive?
- Why is the operator idle?
- Why the delay in part arrival?
- Why the inconsistency in staging?
- Why neglect adjusting the system logic?
✅ Expert Advice
The essence of the 5 Whys technique is not to assign blame but to gain clarity. By focusing on processes over individuals, true solutions emerge. While addressing symptoms may seem quick, tackling the underlying cause fosters sustainable improvement and operational efficiency.
