IASSC Certified Lean Six Sigma Black Belt (ICBB) — Question 42

If one wants to understand the end to end processes in a telecom service, which of the following tools will be helpful in the process improvement?

Answer options

• A. QFD
• B. Cross functional process map
• C. Pareto diagram
• D. SIPOC

Correct answer: D

Explanation

The SIPOC tool is valuable for visualizing the Suppliers, Inputs, Process, Outputs, and Customers in a telecom service, making it easier to identify areas for process improvement. While QFD, cross functional process maps, and Pareto diagrams are useful in different contexts, they do not provide the same comprehensive overview of the entire process as SIPOC does.
