The Personal Software ProcessWhat is PSP:Helps individual
engineers to improve theirperformance by bringing discipline to
theway they develop software.
How to learn it:Remove engineers from day- day environmentand
put them in a rigorous training course.
Advantages of PSP:Less defects, better estimation, improved
planning, and improved quality performance

PSP thoughtsWhat do you think of PSP?
Is it realistic for people to do?
Would you do it?

PSP continued Data Q uality Problems in the Personal Sof t ware
Process, AnneM. Disney, M. S. Thesis, University of Hawaii, August,
1 998.
Examined 89 projects completed by nine subjects using thePSP in
an educational setting (johnsons class). discovered1 539 primary
errors in PSP data.
Findings:-The PSP suffers from a collection data quality
problem.-Manual PSP suffers from an analysis data quality
problem.

The Team Software ProcessWhat is TSP:help integrated

How to learn/do it:PSP training,
launch/relaunchworkshops.
Advantages of PSP:Better plan, lower
defects, better
productivity.

Capability Maturity Model (SW-CMM) for Software
The Capability Maturity
Model for Softwaredescribes the principlesand
practicesunderlying softwareprocess maturity and isintended to
helpsoftware organizationsimprove the maturityof their
softwareprocesses in terms ofan evolutionary pathfrom ad hoc,
chaoticprocesses to mature,disciplined softwareprocesses
(14)
My thoughts.PSP, TSP, CMM are definitely not tailored
for academics.Too restrictiveToo tedious
Id rather stick to hackystat and XP!!!!

Experience Side NotePage 1 , under A question of Conviction most
engineers start off withexceedingly poor personal practices. Asthey
gain experience, some engineers maychange and improve their
practices, butmany do not.
