Passage: Juran was one of the first to write about the cost of poor quality. This was illustrated by his "Juran trilogy," an approach to cross-functional management, which is composed of three managerial processes: quality planning, quality control, and quality improvement. Without change, there will be a constant waste; during change there will be increased costs, but after the improvement, margins will be higher and the increased costs are recouped.

Question: How does the writer suggest improving bad administration work?
quality planning, quality control, and quality improvement
