Quality is internal. Quality must be designed and built into the system. It cannot be forced in through external inspections, and it cannot be tested in. External inspection and test simply indicate the absence of quality. The people on the project must build quality into the products and services they deliver.
Improvement is a continuous process .
Improving quality is not a one-time effort. Continuous improvement means setting new goals each time an objective is met. To improve service and products, you must improve processes by constantly evaluating and revising them as needed. Results must be measured . Merely speculating that you are getting better is not good enough.
