Abstract
Purpose
– The purpose of this paper is to reduce or eliminate the overall equipment effectiveness (OEE’s) speed loss in a lean manufacturing environment.
Design/methodology/approach
– This action research study uses the lean manufacturing 5-whys analysis technique to reduce or eliminate the speed loss.
Findings
– The application of the 5-whys analysis technique in a manufacturing industry (XYZ Corporation) completely eliminated its top speed loss and resulted in a valuable savings of USD 32,811.5 per annum.
Practical implications
– The 5-whys analysis technique which has been primarily known to improve the OEE’s quality loss and changeover loss has been proven to be an effective approach to also tackle speed loss; a loss which has been regarded as the most dominating loss among all the types of OEE’s losses and a difficult one to eliminate.
Originality/value
– Little or no attempt has been made to date to expand the use of the 5-whys analysis technique beyond its originally intended purpose. The lessons learnt in this study could be applied to other organizations. The outcome of the study has also opened the possibility of widening the horizon of the use of the 5-whys analysis technique beyond its original intended objective and could be applicable to solve other losses of OEE and non-value added activities of lean philosophy in general.
