1. Q1.A company tracks its cost of poor quality over three quarters while running an improvement program.
   
   $$\begin{array}{l|c|c|c} \hline \textbf{Quarter} & \textbf{Prevention} & \textbf{Appraisal} & \textbf{Failure} \\ \hline Q1 & 20 & 60 & 320 \\ Q2 & 55 & 58 & 210 \\ Q3 & 70 & 45 & 130 \\ \hline \end{array}$$
   
   All figures are in thousands of dollars. Which conclusion does the pattern best support?

   • A.The improvement program has increased total quality cost
   • B.Prevention spending has reached the point of diminishing return
   • C.Spending more on prevention is being repaid by lower failure cost✓ Correct answer
   • D.The appraisal reduction is the main source of the total saving

   Explanation

   Prevention spending rose from $20$ to $70$, an increase of $50$. Failure cost fell from $320$ to $130$, a drop of $190$. The organization spent an extra $50$ and avoided $190$, so prevention is paying for itself several times over.
   
   Appraisal fell by only $15$, so it cannot account for the saving. Total cost fell from $400$ to $245$, so the program has not increased cost.
   
   Diminishing return would show as failure cost flattening while prevention keeps rising, and the failure column is still dropping steeply.

2. Q2.A team wants to know where on a moulded panel surface defects are occurring, not just how many there are.
   
   Which form of check sheet is most appropriate?

   • A.A defect location check sheet using a drawing of the panel✓ Correct answer
   • B.A tally check sheet listing defect types by count
   • C.A check sheet recording defects by shift and operator
   • D.A check sheet recording the time each defect was found

   Explanation

   A defect location check sheet uses a picture or drawing of the item, and the recorder marks each defect where it appears. Clusters then become visible immediately.
   
   This is often the fastest route to a cause. Defects concentrated along one edge point to handling or to a fixture; defects around a single feature point to the tool at that position.
   
   Counting by type, shift, or time would all be useful, and none of them would show position, which is what the team asked for. See an example below:

3. Q3.A team places four items in a SWOT analysis.
   
   $$\begin{array}{l|l} \hline \textbf{Quadrant} & \textbf{Item} \\ \hline \text{Strength} & \text{Experienced technical staff} \\ \text{Weakness} & \text{New competitor entering the region} \\ \text{Opportunity} & \text{Growing demand in a nearby market} \\ \text{Threat} & \text{Pending change to environmental regulation} \\ \hline \end{array}$$
   
   Which item has been placed in the wrong quadrant?

   • A.Experienced technical staff
   • B.Growing demand in a nearby market
   • C.Pending change to environmental regulation
   • D.New competitor entering the region✓ Correct answer

   Explanation

   A new competitor is outside the organization and is unfavourable, so it belongs under threats rather than weaknesses.
   
   Weaknesses are internal: a skills gap, ageing equipment, a process that cannot hold tolerance. The organization can act on them directly.
   
   The other three are placed correctly. Experienced staff is an internal strength, growing demand is an external opportunity, and a pending regulatory change is an external threat.

4. Q4.A purchasing manager is evaluating four suppliers for a machined component.
   
   $$\begin{array}{l|c|c|c} \hline \textbf{Supplier} & \textbf{Quality (40\%)} & \textbf{Delivery (35\%)} & \textbf{Service (25\%)} \\ \hline \text{Alpha} & 95 & 70 & 60 \\ \text{Beta} & 85 & 90 & 80 \\ \text{Gamma} & 90 & 80 & 70 \\ \text{Delta} & 70 & 95 & 90 \\ \hline \end{array}$$
   
   Which supplier has the highest weighted score?

   • A.Gamma
   • B.Delta
   • C.Beta✓ Correct answer
   • D.Alpha

   Explanation

   A weighted score multiplies each rating by its weight and adds the results:
   
   $$\text{Score} = \sum (\text{rating} \times \text{weight})$$
   
   Working through the suppliers:
   
   $$\text{Alpha} = (95)(0.40) + (70)(0.35) + (60)(0.25) = 77.5$$
   $$\text{Beta} = (85)(0.40) + (90)(0.35) + (80)(0.25) = 85.5$$
   $$\text{Gamma} = (90)(0.40) + (80)(0.35) + (70)(0.25) = 81.5$$
   $$\text{Delta} = (70)(0.40) + (95)(0.35) + (90)(0.25) = 83.75$$
   
   Beta is highest at $85.5$. Alpha has the best quality rating of all four, which is why it draws the eye, but weak delivery and service pull its total to the bottom.
