Planning and Tracking
Logging time, defect, and size data is an essential part of planning and tracking PSP projects, as historical data is used to improve estimating accuracy.
The PSP uses the PROxy-Based Estimation (PROBE) method to improve a developer’s estimating skills for more accurate project planning. For project tracking, the PSP uses the earned value method.
The PSP also uses statistical techniques, such as correlation, linear regression, and standard deviation, to translate data into useful information for improving estimating, planning and quality. These statistical formulas are calculated by the PSP tool.

Famous quotes containing the words planning and, planning and/or tracking:
“...A shadow now occasionally crossed my simple, sanguine, and life enjoying mind, a notion that I was never really going to accomplish those powerful literary works which would blow a noble trumpet to social generosity and noblesse oblige before the world. What? should I find myself always planning and never achieving ... a richly complicated and yet firmly unified novel?”
—Sarah N. Cleghorn (1876–1959)
“For the people in government, rather than the people who pester it, Washington is an early-rising, hard-working city. It is a popular delusion that the government wastes vast amounts of money through inefficiency and sloth. Enormous effort and elaborate planning are required to waste this much money.”
—P.J. (Patrick Jake)
“Such is the art of writing as Dreiser understands it and practices it—an endless piling up of minutiae, an almost ferocious tracking down of ions, electrons and molecules, an unshakable determination to tell it all. One is amazed by the mole-like diligence of the man, and no less by his exasperating disregard for the ease of his readers.”
—H.L. (Henry Lewis)
