Tools of Lean-SixSigma

Lean Six Sigma (LSS) provides the necessary methods, concepts and tools to change a process.(Snee, 2010) One of the main methodologies of LSS is Define, Measure, Analyze, Improve and Control (DMAIC). (Kara- Zaitri, 2013)

If you haven’t read about LSS, then first may-be you should want to read this Lean and Six Sigma

Figure 2.9 illustrates the concept of DMAIC and explains the meaning of each concept and Table 2.1 lists a variety of tools and techniques used in each step. Throughout these articles, we'll refer also to Recommended literature which you are welcome to look up. We update our sources on an ongoing basis.

Successful LSS

A successful organisation that implements LSS would include the following beliefs:

  • Philosophy that is looking to maximize the value added content of operations;

  • A management process that considers the relative impact of decision making on the customer;

  • Would focus mainly on data driven methodologies in decision making process, so that scientific data supports the changes;

  • Design and implement a highly structured education and training system. (Edward & Maleyeff, 2005 and Snee, 2010)

Working with DMAIC

In a lot of cases the approach of implementing LSS with the help of tools like DMAIC, it is underestimated how in detail it should be done. Within each step of DMAIC there are several different sets of tools that can be used to make sure that maximum value is achieved from the process.

Below in table 2.1 you can see a list of tools and techniques that can be used to carry out the different steps of DMAIC.

Flowbase in DMAIC

Flowbase can help with several steps within implementing LSS in your organization. At Flowbase we have automated time and motion study (VSM) annotation, data collection and analysis. Flowbase uses computer vision and AI to automatically analyse any video footage that you upload, enabling you to easily analyse multiple material flows in parallel. All resulting data is gathered to a single dashboard and searchable indexed reports – and if you’re keen to see why the timeline looks the way it does in a particular place, then you can easily refer back to the original video footage. Now, if your production manager wants to compare benchmarks, then it’s a click away. All data is visualised automatically in an easily understandable manner, with historical data and improvements (or regressions) available for each process. If you need to drill down into more detail, then detailed by-the-second data is available in detailed process reports.
