Keeping OEE Data in the Right Place in Lean Manufacturing
OEE(Overall Equipment Effectiveness - Total Equipment Effectiveness) is followed by many manufacturers today. But the question is: is it enough to track OEE, or is it necessary to set ideal targets to achieve real benefits?
What should be our real OEE target?
According to JIPM data, regardless of sector %85 – %93 range is recognized as world-class production.
❓ Peki neden hedef %100 değil?
Çünkü %100 OEE, teoride mümkün olsa da lean production philosophy of continuous and uninterrupted production. Continuous and uninterrupted production does not always lead to cost advantages. On the contrary:
- High inventory costs
- Loss of flexibility
- It can lead to problems such as the inability to respond quickly to customer demands.
OEE Neden %100 Olmaz?
The lean production approach emphasizes not only efficiency but also flexibility, inventory reduction and customer-oriented production. For this reason
- The goal for usability is usually %90 is determined as
- Remaining %10should be allocated to set-up times.
- If many product variants are to be produced, rapid model transitions are required.
This point of view is the main goal of lean production. waste is compatible with reducing and accelerating the flow.
Is High OEE Alone Enough?
Achieving high OEE values despite long set-up times does not always mean you are efficient. In this case, you need to question your production processes. Because
- Continuous production ≠ Efficient production
- High output ≠ Low cost
Lean production is a process that kaizen - requires continuous improvement. The goal is to optimize value generation, not just grow the numbers.
OEE is a Tool, Not a Goal
%100 OEE’yi hedeflemek, üretimi körü körüne maksimize etmek olabilir.
This is their business:
- Cost effectiveness,
- Flexibility,
- It can distract from customer satisfaction.
Real success lies in the hands of enterprises that are capable of balanced, sustainable and strategic production.
Conclusion Go Beyond the Numbers
OEEis one of the indispensable analysis tools of lean production. But it should not be forgotten:
It is not just the numbers that matter, but the meaning and strategy behind those numbers.
✅ Realistic OEE targets, set with a lean production approach, both increase profitability and ensure sustainability.
