Which of the following statements does not correctly describe the modern approach to systems analysis and design?
a) Continued focus on development system for the Internet
b) Move to wireless system components
c) Increase in the use of in-house IT development resources
d) Continuing trend toward assembling systems from components purchased off the shelf
All of the following correctly describe problems with the waterfall approach to systems analysis and design except:
a) Feedback ignored, milestones lock in design specs even when conditions change
b) Limited user involvement (only in requirements phase)
c) Too much focus on milestone deadlines of SDLC phases to the detriment of sound development practices
d) Lack or poor quality of documentation
1.Main actors: testers, programmers
2. This is exactly what it sounds like: users try out the system, find bugs, see if they can break it, and provide feedback to the development team in order to refine the system. Don't think that this is a boring job! This is not like some of those video game testing jobs that students sometimes fill where you simply execute a set of pre-specified sequences in order. Testers have to be creative; their job is to find ways to break the system. This also includes what we call system penetration testing, or "white hat" hacking, which is designed to see if the system can be easily hacked for sensitive data or external control
3. Although there are many types of testing, you should be generally familiar with the following types: (see other terms)
