TSP PSP
PSP is a measurement and analysis framework to
help software developers characterize their
personal processes. TSP is a measurement based
project management and quality management
framework for small to medium size software
teams.

• Team Software
• Process
• Teambuilding
• Risk management
• Project planning and tracking

PSP2.1 Design templates
Introduces quality management and design

• PSP1
• Size estimating
• Test report

• PSP0.1
• Coding standard
• Process improvement
• proposal
• Size measurement

Introduces process discipline and measurement

• PSP0
• Current process
• Basic measures

13
TSP PSP Core Measures

• Effort
• Time on task.
• Size
• Based on a defined standard of unit and a
  counting standard.
• Defect
• Based on defined standard defect types and defect
  recording.

14
TSP Culture

• TSP projects are team-directed (self-managed).
• Being a team-directed project means that the team
  manages itself.
• plan and track their work
• manage the quality of their work
• work aggressively to meet team goals
• The self-management responsibilities are shared
  among team members through a set of defined team
  member roles.

CMMI TSP
Project Management Category
TSP data collection and measurement driven system
satisfies the rigor required QPM.
TSP roles and goals provide the interface to
integrate with other processes.
TSP integrates PP, PMC, and MA into one working
process for individuals and teams.
20
QPM Example
SG1 The project is quantitatively managed using
quality and process performance objectives.
21
QPM Example
SG2 The performance of selected sub-processes
within the project's defined process is
statistically managed.

• TSP Inspection Process Metrics
• Review rate
• Defect density
• Review efficiency (defects found/hour)
• Review effectiveness (Yield)
• Estimate of escapes

Success Factors

• Top management sponsorship engagement not
  just endorsement
• Commitment at all levels
• Proactively providing sufficient resources to
  support the effort
• Assignment of key individuals to the project
• Providing the necessary training
• Managing the effort as a formal, high priority
  project

25
Cultural Transition
Common Culture

• Test over reviews
• Code over design
• "Jumping-in" over planning
• "Guestimates" over estimates
• Opinion over facts

New Culture

• Reviews over test
• Design over code
• Planning over jumping-in
• Estimates over guestimates
• Facts over opinion
