Title: The implementation of a Lean Six Sigma framework to enhance operational performance in an MRO facility Authors: J. Hill, A. J. Thomas, R. K. Mason-Jones and S. El-Kateb Year Published: 2017 Journal: Production and Manufacturing Research Vol 6 Issue 1 Link: https://doi.org/10.1080/21693277.2017.1417179 Tools: DMAIC The article speaks about DMAIC - Define, Measure, Analyze, Improve, and Control. The DMAIC cycle is inherent to Six Sigma and describes the basic logic of a data-centric process improvement approach (Gijo, 2011). In this article, Six Sigma and lean thinking are integrated and applied simultaneously to identify and eliminate disruptions in Order to Receipt times of an aerospace engine Maintenance Repair and Overhaul (MRO) facility. Six sigma DMAIC phases are applied systematically to each of the lean stages (Hill et al, 2017). Think and prepare, specify value, synchronize internal value, stream create flow, pull on demand, and create perfection are the various lean stages described in the article. The output of the define phase of lean stage 1 feeds into the input of the measure stage within lean stage 1. This continues with the output of the measure phase feeding into the analyze phase and so on forming a series of linked activities inside lean stage1. At the end of lean stage 1, the output of the control stage of DMAIC feeds into the define phase of the next lean stage (Hill et al, 2017). Please find attached the lean & Six Sigma integration flow diagram. Standard deviation: No, the article does not speak about standard deviation. Mean, median, mode, and range: The article uses mean (average) to calculate the average Order to Return days and Late Calls days in the results section (Hill et al, 2017). Median, mode and range are not listed in the article. Median, in statistics, is the middle value of a given list of data points when arranged in an order. Mode is the value which occurs the maximum number of times in a data set. Range is the difference between the lowest and highest values. Learnings from the article: The integrated lean six sigma framework allows simultaneous deployment of both the lean and six sigma phases with the aim that the company simultaneously tackles both the waste reduction element and the Critical to Quality element of the business. This approach has several benefits to businesses through its dual focus on reducing waste and increasing value while resolving critical to quality issues that affect consistency and repeatability in a product and process. Six Sigma feeds into and supports the higher level strategic lean implementation process. Six Sigma forms part of a subset of operational strategies that fit into the higher order lean thinking process (Hill et al, 2017).
