The answer is Lean Six Sigma. This technique is correct because it directly targets non-value-added activities by merging Lean’s waste-elimination principles with Six Sigma’s DMAIC framework—Define, Measure, Analyze, Improve, Control—providing a systematic, data-driven approach to process improvement in manufacturing. On the Project Management Professional PMP exam, this question tests your understanding of quality management tools within the Executing and Monitoring & Controlling process groups; a common trap is choosing Lean alone (which lacks structured analysis) or Six Sigma alone (which focuses on variation, not waste). To remember, think of Lean as the “waste remover” and Six Sigma as the “problem solver”—together, they form a powerful hybrid for reducing non-value-added activities. A simple mnemonic: “Lean cuts the fat, Six Sigma fixes the stats.”
PMP Process — Managing Technical Aspects Practice Question
This PMP practice question tests your understanding of process — managing technical aspects. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A project manager is developing a process improvement plan to reduce waste in a manufacturing project. The team has identified several non-value-added activities. Which technique should the project manager use to systematically analyze and improve the process?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Lean Six Sigma
Lean Six Sigma is the correct technique because it combines Lean's focus on eliminating waste (non-value-added activities) with Six Sigma's DMAIC (Define, Measure, Analyze, Improve, Control) methodology for systematic process improvement. This directly addresses the project manager's goal of reducing waste in a manufacturing project through data-driven analysis and continuous improvement.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Pareto analysis
Why it's wrong here
Pareto analysis helps identify the most significant causes but is not a comprehensive improvement framework.
✗
Program Evaluation and Review Technique (PERT)
Why it's wrong here
PERT is for estimating activity durations under uncertainty.
✓
Lean Six Sigma
Why this is correct
Lean Six Sigma provides a structured methodology (DMAIC) for process improvement and waste reduction.

✗
Critical Path Method (CPM)
Why it's wrong here
CPM is used for schedule analysis, not process improvement.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse Pareto analysis (a quality tool for prioritizing issues) with a complete process improvement methodology, but the question specifically asks for a technique to 'systematically analyze and improve the process,' which requires a structured framework like Lean Six Sigma, not just a prioritization tool.
Detailed technical explanation
How to think about this question
Lean Six Sigma integrates two complementary methodologies: Lean targets 'muda' (waste) in seven categories (defects, overproduction, waiting, non-utilized talent, transportation, inventory, motion, extra-processing) while Six Sigma uses DMAIC to reduce process variation to 3.4 defects per million opportunities. In practice, a project manager would use value stream mapping (a Lean tool) to identify non-value-added steps, then apply Six Sigma statistical controls to ensure improvements are sustained, making this a comprehensive approach for manufacturing waste reduction.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
