Chapter Overview
What? A software process - a series of predictable steps that leads to a timely,
high-quality product.
Who?
Managers, software engineers, and customers.
Why? Provides stability, control, and organization to an otherwise chaotic
activity.
Steps? A handful of activities are common to all software processes,
details vary.
Work product?
Programs, documents, and data.
Correct process? Assessment, quality deliverable.

Define The Discipline
Software Engineering
The application of a systematic, disciplined, quantifiable approach
to systematic, disciplined, quantifiable approach to the development,
operation, and maintenance of the development, operation, and
maintenance of software; that is, the application of engineering to
software;
Systematic disciplined, quantifiable.
Software Engineering is a layered technology.

Software Engineering Practice
The Essence of Practice
Understand a Problem
- who stake in solution of problem
- what are the unknown
- can be graphically representable
Plan a Solution
- has solved similar problem
- can sub problem defined

Software Engineering Practice
Carry out the plan
- does solution related with plan
- all solution make correct sense
Examine the result
- if possible test each component part
