These can be pure software teams or integrated product teams (IPTs) of 3 to about 20 engineers.
Why is PSP important?
PSP stresses the need to identify errors early and, just as important, to understand the types of errors that you are likely to make. PSP represents a disciplined, metrics based approach to software engineering that may lead to culture shock for many practitioners.
What is software process?
A software process (also knows as software methodology) is a set of related activities that leads to the production of the software. These activities may involve the development of the software from the scratch, or, modifying an existing system. Any software process must include the following four activities:
What is software specification?
Software specification (or requirements engineering): Define the main functionalities of the software and the constrains around them.

By developing the software incrementally, it is cheaper and easier to make changes in the software as it is being developed .
Why are initial versions of software produced early?
Initial versions of the software are produced early, which facilitates customer evaluation and feedback.
Why is reuse important in software engineering?
Reuse-oriented software engineering has an obvious advantage of reducing the amount of software to be developed and therefore reduced cost and risks , and usually leads to faster delivery. However, requirements compromises can’t be avoided, which may lead to a system that does not meet the real needs of users.
How to reduce prototyping costs?
To reduce the prototyping costs and accelerate the delivery schedule , you may ignore some functionality, such as response time and memory utilization unless they are relevant to the objective of the prototype. Develop the prototype: The initial prototype is developed that includes only user interfaces.
What is system integration?
Development and integration: The components are integrated to create the new system. System integration, in this model, may be part of the development process rather than a separate activity. There are basically three types of software components that can be used in a reuse-oriented process:

What will software engineering be required to do in the future?
In the future, software engineering groups will increasingly be required to deliver qualityproducts, on time, and for their planned costs. Guaranteed reliability and service levels, war-ranted security, and contract performance penalties will be normal and engineering staffs thatcannot meet such commitments will not survive.
What is the PSP quality principle?
The first PSP quality principle is that engineers are personally responsible for the quality ofthe programs they produce. Because the software engineer who writes a program is most fa-miliar with it, that engineer can most efficiently and effectively find, fix, and prevent its de-fects. The PSP provides a series of practices and measures to help engineers assess the qualityof the programs they produce and to guide them in finding and fixing all program defects asquickly as possible. In addition to quality measurement and tracking, the PSP quality man-agement methods are early defect removal and defect prevention.
