Comprehensive and Detailed Explanation (paraphrased from CIPS L4M2 content)
Standardising from many similar products to one common product is a classic variety reduction / standardisation decision.
In CIPS L4M2, when standardisation is discussed, the benefits highlighted include:
Economies of scale -- buying larger quantities of a single product allows for better prices and volume discounts.
Reduced administration and handling costs -- only one product code to manage, fewer invoices and orders, simpler stock control.
Simplified quality control -- one specification and one performance profile to monitor.
Because the product is available from many suppliers, competition remains strong. This supports lower prices, not higher.
Option A (Lower costs) -- correct, due to economies of scale and reduced process/handling complexity.
Option B (Fewer staff) -- staff numbers are driven by overall workload, not just the number of product variants; standardising doesn't automatically cut headcount.
Option C (Increased stock levels) -- if anything, standardisation often reduces safety stock (you can pool demand into one line).
Option D (Increased costs) -- contradicts the expected benefits of standardisation and competition between many suppliers.
