The Lean Glossary

Lean GlossaryEmbarking on a lean journey bodes well for the future success of your manufacturing operation, although it can feel like entering a minefield of terminology. You’ll soon discover that a little advice can go a long way.

As leading providers of integrated OEE software, Idhammar recognises the importance of complete visibility, in terms of both production performance and understanding OEE concepts, in order to drive a programme of continuous improvement.

So, we’ve put together The Lean Glossary of common terms and phrases used in the world of lean manufacturing, OEE and Continuous Improvement, to help lessen the confusion and improve your understanding of all things lean. You can’t go wrong!

5 Whys Problem solving technique, ask why 5 times
5S Sort out, Set limits & locations, shine, standardise, Systemise & sustain

Bottleneck  At asset whose performance or capacity limits the rest of the process
CANDO Clear out, Arrange, Neat & Clean, Discipline, Ongoing Improvements
CI Continuous Improvement, a methodology based on tools and techniques which helps resolve business issues in a sustained and logical manner
Cycle Time Total amount of time it takes for defined steps in a process to be completed
DMAIC Steps used in CI methodology, Define, Measure, Analyse, Improve, Control
FMEA Failure Mode and Effects Analysis, a structured approach that identifies and documents possible failure modes, effects of failures, causes, and associated corrective actions, includes a weighted approach to quantify Occurrence, Detection, and Severity elements
