Lean Six Sigma is a data-based process improvement methodology that evolved from the Lean methods from Toyota’s 1930 “The Toyota Way” and Six Sigma, a set of techniques and tools introduced by American engineer Bill Smith while working at Motorola in 1986. There is a need to understand the relevance of process improvement methods introduced during the third industrial revolution, specifically Lean Six Sigma, in high-tech companies leading the charge during the fourth industrial revolution. My research topic aims to answer the following questions:

  • What process improvement practices are commonly being used to advance operational excellence in digital high-tech companies.
  • How effective are these practices?
  • How do these practices bundle in a systematic approach for data-driven process improvement and how does this compare to existing structures for data-driven process improvement such as Lean Six Sigma?
  • What is the philosophy that serves as the integrating model (the dominant philosophy/ methodology)?
