Control of Quality – Quality management
The most fundamental concept of modern quality management is that quality is built into a project through the teamwork of the people planning and executing the work. Projects must have stable and effective processes. Quality is not achieved by searching for and removing errors that were allowed to creep in earlier.

This concept is absolutely consistent with the Project Management Method as taught in this course. Quality must be designed into a project at every stage – not inspected after the fact.

In the olden days, before the industrial era, the tailor, the carpenter, the shoemaker, the milkman, and the blacksmith knew his customers by name. He knew whether they were satisfied, and what he should do to improve appreciation of his product.
