What is budgetary slack and why does it matter?

Intermediate

Answer

Budgetary slack is deliberately understating revenues or overstating costs when setting a budget to make targets easier to achieve. It arises especially in participative budgeting. It matters because it wastes resources, distorts planning and performance measurement, and can hide inefficiency; controls include review, benchmarking, and linking rewards carefully.
Real-world example A manager pads the expense budget by 15% to ensure they comfortably beat it and earn a bonus.
