The Personal Software Process (PSP) is based on the following planning and quality principles:
Every engineer is different; to be most effective, engineers must plan their work, and they must base their plans on their own personal data.
To consistently improve their performance, engineers must personally use well-defined and measured processes.
To produce quality products, engineers must feel personally responsible for the quality of their products. Superior products are not produced by mistake; engineers must strive to do quality work.
It costs less to find and fix defects earlier in a process than later.
It is more efficient to prevent defects than to find and fix them.
The right way is always the fastest and cheapest way to do a job.
