Lean Features

Value Network Mapping by Shahrukh A. Irani

Kaizen-The systematic, organized improvement of processes by those who operate them, using straightforward methods of analysis. It is a "do it now" approach to continuous incremental improvement to create more value with less muda. Kaizen establishes what needs to be done and instills the principles of continuous improvement. Also call point kaizen, process kaizen or blitz.

Cycle time-The total time one piece of product or one transaction resides in a process activity. It includes the setup time, process time, waiting for other units processed in the batch until the batch is released to the next process step.

Ask the Expert

Question: What is the difference between Lean and Six Sigma methodologies?

Answer: Essentially, Six Sigma and Lean systems have the same goal. They both seek to eliminate waste and create the most efficient system possible, but they take different approaches toward achieving this goal. In simplest terms, the main difference between Lean and Six Sigma is that they identify the root cause of waste differently.

Lean practitioners believe that waste comes from unnecessary steps in the production process that do not add value to the finished product, while Six Sigma proponents assert that waste results from variation within the process.

Of course, there is truth in both of these assessments, which is why both Lean and Six Sigma methodologies have been so successful in improving overall business performance in a variety of fields. In fact, these two disciplines have proven to be especially successful when working in tandem - hence the creation of Lean Six Sigma.
