OEE Myths – part 2

In Top OEE Myths Part 2, we continue our journey to review and dispel certain misconceptions that have grown around the OEE and OEE Software.

Myth 6 – We Use Softer Target Speeds When Planning

The important thing when planning production is to ensure that the target dates that customers are quoted are actually met. This often gets translated into allowing buffers into the system by way of adding on percentages here and there to account for unplanned delays.

This is not how OEE works. OEE software will always seek out the shortest path for the completion of any job or process. Regular plant and equipment servicing and maintenance routines are an intrinsic part of the OEE process of determining optimum production.

  • Work to the path laid down by the OEE process
  • Optimise production
  • Reduce lead times
  • Increase confidence in meeting client deadlines.

Myth 7 – Planned Events are Excluded from the OEE Process

Planning is one of the fundamentals of any OEE system. Without proper planning there will be chaos.

  • The supply of raw materials may be interrupted
  • Production changeover targets may become obscured
  • Regular maintenance routines will get postponed
  • Downtime will have a cumulative ripple effect
  • Inefficiencies will dramatically increase.

Given that planning is therefore essential to avoid any of these events taking place, it does not however mean that planned events should be excluded from the OEE process. In fact quite the reverse is true. Planned events are the very oxygen that any OEE system operates on. But in order to promote Kaizen (continuous change), and to encourage leaner manufacturing, OEE software analyses all aspects of any production cycle, measuring and cataloguing any events within the cycle that cause delays and stoppages.

  • Nothing should be excluded from the OEE analysis process
  • OEE is the catalyst for change
  • Change must be a continuous process (Kaizen)
  • Opportunities for change must always be acted upon.

Continuous production will inevitably breed inefficiencies, but by allowing the OEE process to follow the path outlined above, these inefficiencies will be minimised as the principle of Kaizen is targeted to a leaner production process. It is a recognised fact that companies that install one of Idhammar’s OEE programs experience a 10% increase in their OEE score within the first six months.

Myth 8 – Trying to Attain World Class Production Figures of 85%

A figure of 85% in a company’s OEE score has somehow become accepted as translating into world class production. This is a misconception because:

  • No two companies are identical
  • No two production processes are absolutely identical
  • Circumstances continually change across the world
  • Environments continually change across the world

The process of continuing to seek improvement is incongruous to having a fixed target. Whereas 85% may be seen as world class in one industry, in another, 90% may be the norm. Continuous improvement towards a leaner process means just that – continuous. The search for the perfect production process is an everlasting one.
