In this chapter we are going to briefly study the defects and their origins.
Defects may originate from different places throughout the software development life cycle.
Here we are studying the defects and how to solve those raised defects by using different approaches.
We are mainly focused on defect sources,origin for defects,Impact on software aircraft,Impact from users view.
We are going to discuss these things one by one.
Origin of defects:
Defects have detrimental effects on software users.
Even under the best of development circumstances errors are made,resulting in the defects being injected into the software during different phases of the software life cycle.
These may cause as we said earlier these decrease the quality of the software product we are developing.
These may come from the requirement specification and resource allocation phase to coding and testing and sometimes until the debugging phase.
These may be handled if we have proper knowledge on the domain and the software engineering disciplines.
