Focused Improvement is a TPM and Lean practice for attacking priority losses, chronic problems, and recurring performance gaps with structured team-based improvement.
Definition
Focused Improvement is a structured improvement practice aimed at eliminating priority losses and chronic problems. In TPM, it is often treated as one of the core pillars and is used to improve equipment effectiveness, quality, safety, throughput, and cost by targeting specific loss categories.
The phrase is intentionally practical: do not try to improve everything at once. Identify the most important loss, understand the mechanism, remove root causes, and standardize the gain.
History
Focused Improvement developed through TPM and Lean practice as organizations moved from reactive maintenance and broad improvement campaigns toward loss-driven, cross-functional improvement. TPM loss structures such as breakdowns, setup, minor stops, speed loss, defects, and startup losses gave teams a way to prioritize improvement work.
It aligns closely with Kaizen, DMAIC, A3, and daily management. The method is common in manufacturing but also applies to service operations where recurring losses can be defined and measured.
When to Use
Use Focused Improvement when a recurring loss is large enough to deserve team attention: downtime, scrap, rework, minor stops, changeover loss, yield loss, safety incidents, energy waste, or chronic customer complaints. It is especially useful when the loss has been accepted as normal.
Focused Improvement also fits portfolio management. Leadership can direct limited improvement capacity toward the few losses that matter most to safety, quality, delivery, cost, and morale.
Step-by-Step
- Select the loss. Use Pareto, OEE, COPQ, safety, customer, or delivery data to choose a meaningful target.
- Define the problem. Specify where, when, how often, how much, and under what conditions the loss occurs.
- Build the team. Include operators, maintenance, quality, engineering, supervision, and support functions as needed.
- Observe the process. Go to the gemba and confirm actual conditions, not just report summaries.
- Analyze causes. Use 5 Whys, Fishbone, data stratification, equipment checks, or process studies.
- Implement countermeasures. Focus on prevention, restoration, standard conditions, mistake proofing, and process control.
- Verify results. Compare before and after performance using the original loss measure.
- Standardize. Update standard work, maintenance routines, training, visual controls, and reaction plans.
- Replicate learning. Apply proven countermeasures to similar equipment, lines, or processes.
Examples
- Minor stops: A packaging line attacks repeated short stops by improving guides, cleaning standards, and material staging.
- Scrap: A molding team focuses on one defect family and stabilizes settings, material handling, and startup checks.
- Changeover: A team reduces setup loss by separating internal and external work and standardizing tool preparation.
- Energy use: A facility targets compressed-air leaks as a focused improvement theme.
- Service delay: A claims team focuses on one recurring handoff delay that drives most late responses.
Common Pitfalls
- Choosing too many targets. Focused Improvement loses power when everything is a priority.
- Skipping loss quantification. Teams need a clear baseline and financial or operational impact.
- Jumping to fixes. Chronic losses usually need mechanism understanding, not quick guesses.
- No operator involvement. Frontline knowledge is essential for practical countermeasures.
- Weak sustainment. Gains disappear without standards, ownership, and review routines.
- No replication. Lessons from one asset or process should be shared where similar losses exist.
