Six Sigma includes use of tools such as I. descriptive statistics, run charts, and process control charts. II. check sheets, Pareto charts, and benchmarking. III. Brainstorming, force field analysis, and cause and effect diagrams. IV. counter-seasonal production scheduling.

I, II, and III only

Explanation:

Here is the complete question:

Six Sigma includes use of tools such as

I. descriptive statistics, run charts, and process control charts.

II. check sheets, Pareto charts, and benchmarking.

III. Brainstorming, force field analysis, and cause and effect diagrams.

IV. counter-seasonal production scheduling.

Which of the options is correct?

1) I, II, and III only

2) IV only

3) I and II only

4) none of the above

5) all of the above

Lean Six Sigma is a method which relies on collaborative team effort in order to improve performance through the removal of waste and reduction in variation.

In lean six sigma, the control chart and run charts are used to know whether the overall process utilised is resulting in the best possible outcome. This is done through the measurement of variation.

Benchmarking is also used in lean six sigma by organizations in comparidon of their output performance to that of a standard. Brainstorming is the most valuable stage during the Define phase, in lean six sigma especially when using tools such as failure mode and effects analysis.

This shows that options I, II and III are correct, therefore option 1 is the right answer
