What is a Software Development Process?
A software development process, also known as
a software development life cycle, is a set of activities,
methods, and practices that are used in the
development of software. There are several models for
such processes, each describing approaches to a variety
of tasks or activities that take place during the process. It
helps us build and deliver high quality software to
satisfy customers/ market demands.
Software development activities
1
• Planning
2
• Implementation, testing and
documenting
3
• Deployment
and
maintenance
What is software development
model?
To develop software products, software engineers must
establish a strategy consisting of the process, methods
and tools, organizing them into a structure that guides
the development called “Software Development Model”.
Several models exist to streamline the development
process. Each one has its pros and cons, and it's up to the
development team to adopt the most appropriate one for
the project. Sometimes a combination of the models may
be more suitable.
Waterfall Model
is a tradition model, linear, sequential, this model is very risky.
It just have followed sequential a thorough process, so if the
previous phases have mistakes then the project is failure.
Spiral Model
How the TSP was developed?

In 1996, Watts
Humphrey developed
the initial version of the
TSP process. His
objective was to provide
an operation process to
help engineers
consistently do quality
work.

What is Team Software Process?
Team Software Process (TSP) guides engineering teams that
are developing software-intensive products. Using TSP helps
organizations establish a mature and disciplined engineering
practice that produces secure, reliable software in less time
and at lower costs
TSP is a process that is specifically designed for software
teams. It’s purpose is to build high performance teams and
help them :
 plan their work
 negotiate their commitments with management
 manage and track projects to a successful conclusion
 produce quality products in less time
 achieve their best performance without the “death march”
ending

Why focus on teams?
Launching a TSP team
Launching a TSP team
The team leader






guide and motivate the team in
doing its work
take the time to reach full
consensus on all important issues
ensure that the team establishes
high standards for the work
provide management support to the
team
support the team with management
protect the team so that it can
concentrate on the project
The team leader’s job is to use the
team to build the product.
The coaches
• trains and facilitates the adoption of
TSP
• works with the team leader to build
the team
• observer that guides the team
The coaches job is to use the
project to build the team.

The TSP Team working Process
Once the TSP team is launched, the principal
need is to ensure that all team members follow
the plan. This includes major topics:

TSP Quality Management
Planning for quality
 TSP quality planning estimates the number of defects
injected and removed at each phase based on historical
injection rates and phase yields.
 Removal rates, review rates, phase time ratios, defect
densities, and other quality indicators are then
calculated by the tools.
TSP Quality Management
Measuring and tracking quality
 Developers track every defect found and fixed.
 Quality is reviewed weekly by the quality manager and
the team.
TSP Quality Management
Defect removal filters
 Every activity that finds and removes defects can be
thought of as a defect removal filter
 TSP has many such filters.
Capture/Recapture
 TSP uses capture/recapture to estimate the defects
missed in inspections.
Defect prevention
 Every defect found in system test or later is analyzed to
prevent future escapes.
 Every defective module is re-inspected.

Advantages of TSP Model




Members of the team can support each other.
Reductions in cost and schedule variance to less than
+/- 10%
Self-directed teams: develop their own plans, negotiate
commitments, track their work, keep management
informed of project status and risks.
Productivity improvements of 25% or more. TSP have to
planning for quality: estimates the number of defects
injected and removed at each phase. It also measure and
track quality: Developers track every defect found and
fixed. Quality is reviewed weekly by the quality manager
and the team.
Advantages of TSP Model

TSP schedule, time granularity is in hours, not
days, weeks, or months. Time is a measure of time on
task. Minus interruption time. TSP team members
record their time as they work, not at the end of the
day, week, or month.
Disadvantages of TSP Model


Training problem: It will take a lot of cost and time
to training all the team.
TSP model is suitable for big project with high
risk because it is a complicated. TSP projects are
divided into cycles. Each cycle starts with a launch or
relaunch and ends with a postmortem.
