Productivity in research is more difficult to define since the output is less easily quantified.

  • Six Sigma Performance improvement based on ideas developed at Motorola and earlier industrial improvement methods. Particular emphasis is placed on reducing errors and variation. Statistical tools are employed. It shares many tools with the Lean method. Due to this overlap the term Lean Six Sigma (LSS) is sometimes used.

  • System Interconnected components in a group with an overall purpose.
