Question 88: What is the main focus of Six Sigma?

To standardize all processes
To increase output volume
To eliminate waste
To reduce defects and variability (Correct answer)

Correct answer: To reduce defects and variability

Six Sigma is a data-driven methodology primarily focused on improving process quality by identifying and removing the causes of defects and minimizing variability in manufacturing and business processes. Its goal is to achieve near-perfect performance, where processes produce very few errors or defects, leading to highly consistent and reliable outputs.

Question 89: Which of the following best defines 'vertical integration' as an operations strategy?

Implementing multi-level management layers to oversee operations
Partnering with competitors to share production capacity
Acquiring control over additional stages of the supply chain upstream or downstream (Correct answer)
Expanding product lines to serve more customer segments

Correct answer: Acquiring control over additional stages of the supply chain upstream or downstream

Vertical integration extends a company's ownership into supplier (backward) or distributor/retailer (forward) stages to gain control over quality, cost, and delivery.

Question 90: In operations management, what does 'automation' primarily help achieve?

Higher throughput with reduced human error and labor costs (Correct answer)
Elimination of all quality checks
Increased reliance on manual inspection
Slower production for higher quality

Correct answer: Higher throughput with reduced human error and labor costs

Automation uses technology to perform repetitive tasks faster and more consistently than humans, increasing output while reducing errors and labor expenses.

Question 91: Which risk monitoring technique involves setting predefined thresholds that trigger escalation when breached?

Risk auditing
Risk threshold monitoring with KRIs (Correct answer)
Qualitative risk scoring
Risk reassessment

Correct answer: Risk threshold monitoring with KRIs

KRI thresholds define acceptable risk levels; when a metric crosses the threshold, it automatically signals that management action is required.

Question 92: What role does risk management play in operations planning?

To avoid employee training
To lower production costs
To identify and mitigate risks (Correct answer)
To improve customer satisfaction

Correct answer: To identify and mitigate risks

Risk management is integral to operations planning as it proactively identifies potential disruptions, failures, or threats that could impact operational continuity and goals. By identifying and mitigating these risks, organizations can minimize negative impacts, ensure smoother operations, and protect their assets and reputation.

Question 93: Which tool is MOST useful for an Operations Manager conducting a structured one-on-one meeting with a direct report?

Correct answer: Agenda with prepared discussion questions

A structured agenda with prepared questions ensures one-on-ones are productive, consistent, and cover development and performance topics.

Question 94: An operations team uses a traffic-light reporting system (red/yellow/green) for KPIs. What is the PRIMARY risk of this approach?

It cannot be used for financial metrics
Employees prefer numerical data only
It requires expensive software to implement
Threshold boundaries may oversimplify nuanced performance trends (Correct answer)

Correct answer: Threshold boundaries may oversimplify nuanced performance trends

Color-coded systems can mask gradual deterioration or improvement because metrics near threshold boundaries receive the same color as those far from them.
