Exam 12: Moving Into Implementation

Bridget is managing a systems development project.The programmers have gotten farther and farther behind in the schedule.One thing she should NOT do is:

The fourth phase of the SDLC is the _________ phase

System documentation takes all the processes,notes,diagrams from systems analysis and systems design and puts it in a project binder for future reference.

Black-box testing is used for normal unit testing

During the implementation phase of the Systems Development Life Cycle (SDLC),systems analysts spend their time writing programs and coding applications.

Beta tests make use of real data.

The authors suggest that:

Tutorials teach people how to use major components of the system.

Good-quality paper documentation usually takes about 8 hours per page (double-spaced).

With some software systems,a day of down-time caused by a software bug can cost more than several programmers' annual salaries.

One of the mistakes of system development is:

If a program module is taking longer to develop than expected,generally the most appropriate approach is to move the expected completion date back by the same amount of time that the module will be late.

Even if there were flaws in the analysis and design phases,those can easily be overcome in the implementation phase.

What are some classical implementation mistakes and how can you avoid them?

An example of a fairly recent enhancement to online help functionality that uses intelligent agents might be:

When testing individual modules,it sometimes happens that some modules are not finished when testing starts,so the programmer usually writes _______ for the unfinished modules to enable the modules around them to be tested.

During program design - and again here in the actual programming coordination,we find that it is best to have modules that overlap and have high coupling and low cohesion.

One of the best books on managing projects (and was written in 1975)is:

User documentation includes such things as logical ERDs,logical DFDs,use-cases,physical ERDs,physical DFDs and screen mockups.

Software bugs are estimated to cost the US economy $12.4 million dollars a year.
