In an FMEA, detection rating is high if

  1. The control certainly detects potential failure cause

  2. There are high chances that the control will detect the potential failure cause

  3. There is moderate chance of control detecting the potential failure cause

  4. There is no control or the control can not detect the potential failure cause
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In FMEA, Detection rating measures how likely controls are to detect a failure. A HIGH detection rating means POOR detection - the control is unlikely to catch the failure. This is counterintuitive: high rating = high risk. Options A and B describe good detection (low rating). Option C is moderate. Option D correctly states that high detection means no or ineffective controls.

In COPIS, what is "P" stands for

  1. Product

  2. Process

  3. Program

  4. Procedure
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

COPIS is a SIPOC variant viewed from the Customer perspective. The acronym stands for Customer - Output - Process - Input - Supplier. This helps teams understand processes starting from the customer's viewpoint. 'P' stands for Process, representing the transformation steps that create value.

In Define Phase, we would identify

  1. Our Customers and their Requirements for our products and services

  2. Our Customers and their solutions for our products and services

  3. The causes for our customers' pain

  4. Our Customers VOC and the solution they would like us to implement
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Define phase focuses on understanding the customer and their requirements (Voice of the Customer). Identifying solutions (B) happens in Improve phases. Root cause analysis (C) occurs in Analyze. Implementing customer solutions (D) is premature in Define - first we must understand WHAT they need, not HOW to solve it.

In FMEA lower RPN value indicates that __________

  1. The risk has to be mitigated immediately

  2. The risk has low impact

  3. Risk is beyond human control

  4. RPN does not have any relation to risk
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

RPN (Risk Priority Number) = Severity × Occurrence × Detection in FMEA. Lower RPN indicates lower overall risk - either low impact, rare occurrence, or good detection. High RPN requires immediate mitigation (A). RPN directly quantifies risk, so option D is incorrect. Lower RPN means the risk has lower priority or impact, making option B correct.

In which phase of DMAIC would you brainstorm for solutions

  1. Control

  2. Measure

  3. Analyze

  4. Improve
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

DMAIC phases: Define (the problem), Measure (current performance), Analyze (root causes), Improve (develop and implement solutions), Control (sustain gains). Brainstorming solutions is the core activity of the Improve phase. Control (A) focuses on monitoring. Measure (B) is data collection. Analyze (C) identifies causes but doesn't generate solutions.

Measure of Central Tendency for long tailed graph is

  1. Mean

  2. Median

  3. Mode

  4. Quartile
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Median is the best measure of central tendency for skewed or long-tailed distributions because it is not affected by extreme values. The mean would be pulled toward the tail, mode may not represent the center, and quartile measures spread rather than central tendency.

Measurement variation is introduced when _________

  1. The process undergoes unexpected variation

  2. The process is running at highest performance level

  3. The process is being measured

  4. The measurement follows the Process output
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Measurement variation occurs because the act of measuring introduces additional variability beyond the actual process variation. Even with perfect instruments, some measurement error always exists. This is why we separate total variation into process variation and measurement system variation.

Mistake proofing is _______

  1. A method of identifying potential defects

  2. A technique for eliminating errors by making it impossible to make mistakes in the process

  3. A means of responding to defects before they leave the facility

  4. Part of Statistical Process Control
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Mistake proofing (Poka-Yoke) designs processes so that errors cannot occur or are immediately detectable. Unlike inspection which finds defects after they occur, mistake proofing prevents them at the source. This is a core Lean quality technique.

Observed variation is

  1. The True variation

  2. The summation of true variation & bias

  3. The difference between true variation & bias

  4. The bias
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Observed variation includes both the actual process variation and any bias in the measurement system. We distinguish between true process variation and measurement system variation to understand total variability. Bias systematically shifts measurements away from true values.
