LTW OF SOFTWARE SYSTEM
Abol Ardalan · 1999
The major difference in the estimation of software LTW with the type of systems we have been discussing so far is in the estimation of its development cost. Software development involves more than writing codes. It is a systematic process that analyzes the requirements, prototypes and designs alternative approaches, then implements, tests, and delivers an automated solution. Traditional software development is performed in stages, from requirements gathering and analysis, through customer acceptance, and transition to operations and maintenance. The overall process is defined as the software lifetime.
