Question 16. Which statistical tool is most appropriate for monitoring a process’s stability over time? A) Pareto chart B) Histogram C) Control chart D) Scatter diagram Answer: C Explanation: Control charts display variation and detect shifts, indicating whether a process is in statistical control. Question 17. In computational fluid dynamics (CFD), what does the Courant‑Friedrichs‑Lewy (CFL) condition ensure? A) Conservation of mass B) Numerical stability of the time‑step size C) Turbulence modeling accuracy
Answer: A Explanation: In a firm‑fixed‑price contract, the contractor absorbs cost overruns, bearing the most risk. Question 20. In a program, a “critical chain” focuses on managing which resource? A) Financial budget B) Human resources C) Project schedule buffers D) Material supply Answer: C Explanation: Critical chain project management adds buffers to protect the schedule from resource constraints. Question 21. Which of the following is a primary benefit of using Design of Experiments (DOE) in product development? A) Reducing the number of required prototypes by evaluating multiple factors simultaneously B) Eliminating the need for statistical analysis C) Guaranteeing zero defects in the final product D) Simplifying the bill of materials
Answer: A Explanation: DOE systematically studies factor effects, allowing fewer experiments while gaining comprehensive insight. Question 22. In the context of ISO 14001, what does the term “significant environmental aspect” refer to? A) Any aspect that affects the environment, regardless of magnitude B) An aspect that can cause a substantial environmental impact, either positive or negative C) Only aspects that are regulated by law D) Aspects related to employee health and safety Answer: B Explanation: Significant aspects are those with the potential for notable environmental consequences and thus require control. Question 23. Which of the following best describes the “scope creep” phenomenon? A) Adding resources to accelerate the schedule B) Uncontrolled expansion of project scope without corresponding adjustments to time, cost, or resources C) Reducing deliverables to meet budget constraints
Answer: B Explanation: Smart materials adapt (e.g., shape‑memory alloys, piezoelectrics) when exposed to temperature, electric fields, etc. Question 26.
