Common mistakes to avoid

Questions where students often pick the tempting wrong answer — make sure you know the right one:

Kaizen is BEST described as.✗ Big one-off changes   ✓ Continuous small improvements
Does buying in bulk always save a business money overall?✗ Bigger orders are always cheaper for the business overall.   ✓ Bulk-buying lowers the price per unit, but it raises storage costs, ties up cash and risks waste if demand falls — the net effect depends on the product.
Does higher productivity mean employees are working longer hours?✗ The only way to raise productivity is to make staff work more hours.   ✓ No — productivity is output per worker per time period; it rises through better training, equipment and methods, not necessarily longer hours.
