4
The Logic of the TSP

• Most industrial software is developed by teams
• To be an effective engineer ? to be able to work
  on team
• Teams must plan projects, track progress, and
  coordinate work

5
The Logic of the TSP

• Why projects fail?

6
The Logic of the TSP

• What is a Team?

7

• A team consists of
• at least two people, who
• are working toward a common goal/obj/mission,
  where
• each person has been assigned specific roles or
  functions to perform, and where
• completion of the mission requires some form of
  dependency among group members
• Dyer,1984

8
Basic Teamwork Conditions Cummings, Mohrman

• The tasks to be done are clear and distinct
• The team is clearly identified
• The team has control over its tasks

9
Building Effective Teams

• Team cohesion
• Challenging goals
• Feedback
• Common working framework

10
Introduction to TSP

• Watts Humphrey developed the TSP to provide an
  operational process to help engineers
  consistently do quality work
• Teams are required for most engineering projects
• Systems development is a team activity and the
  effectiveness of the team largely determines the
  quality of the engineering

11
Introduction to TSP

• A team is a group of people who share a common
  goal
• Teams require common processes they need agreed
  upon goals and they need effective guidance and
  leadership
• To be effective, teams must be properly skilled
  and be able to work as cohesive units

12
Introduction to TSP

• TSP provides a defined operational process to
  guide engineers and managers through the
  team-building steps
• With a defined process and a plan that follows
  that process, engineers can be highly efficient

13
TSP objectives

• TSP has 5 objectives
• To build self-directed teams that plan and track
  their work, establish goals, and own their
  processes and plans
• To show managers how to coach and motivate their
  teams and how to help them sustain peak
  performance

14
TSP objectives

• To accelerate sw process improvement by making
  CMM level 5-type behavior normal and expected
• To provide improvement guidance to high-maturity
  organizations
• To facilitate university teaching of
  industrial-grade team skills

15
TSP Principles

• The engineers know the most about the job and can
  make the best plans
• When engineers plan their work, they are
  committed to the plan
• Precise project tracking requires detailed plans
  and accurate data
• Only the people doing the work can collect
  precise and accurate data
• To minimize cycle time, the engineers must
  balance their workload
• To maximize productivity, focus first on quality

16
The Structure of the TSP

• The principal elements of the TSP process are
  shown in figure 2
• Before engineers can use the TSP, they need to be
  trained in the PSP.
• TSP shows the engineering groups how to apply
  integrated team concepts to the development of
  sw-intensive systems
• It walks teams and their management through a
  4-day launch process, ? called Team Launch

TSP Principal Elements
19
The TSP Launch

• 1st step in developing a team is to plan the work
  ?done during the TSP launch (led by a qualified
  team coach)
• In a TSP launch
• the team reaches a common understanding of the
  work
• and the approach they will take,
• produces a detailed plan to guide the work, and
• obtains mgt support for the plan

Summary

• The TSP enables team projects to save time and
  effort by providing explicit guidance on how to
  accomplish their objectives
• The principal benefit of the TSP is that it shows
  teams of engineers how to produce a quality
  products for planned costs and on aggressive
  schedules
• By making them owners of their plans and
  processes
