ITPEC IP April 2026 Question 1
When the reward for an improvement proposal concerning business operations is determined based on the decision table below, how much is the reward for an improvement proposal for an improvement of $20,000 and a turnaround time reduction of three days? Here, “Y” in the table means that the condition holds, and “N” means that the condition does not hold. In addition, “√” indicates the reward that applies to a specific combination of these conditions.
Explanation
$100 — read each condition as Y or N for this proposal, then take the rule column that matches both.
- •Improvement of $20,000: "less than $10,000" is N
- •Turnaround time reduction of three days: "less than one week" is Y
The rule column with N, Y is the third column, and its √ is on the $100 row.
Answer (b)
Why not others:
- •(a) $50 — the Y, Y column: it takes the $20,000 improvement as less than $10,000
- •(c) $150 — the Y, N column: both conditions read the wrong way round
- •(d) $300 — the N, N column: it takes three days as not less than one week
Key rule: A decision table lists every combination of condition outcomes as a column; evaluate each condition separately, find the one column whose Y/N pattern matches, and apply only the action marked in it.
