Exam 11: Systems Development and Procurement
What is rapid application development? Explain.
A common approach used in iterative methods that helps software developers bring an application to life more quickly is called rapid application development. Developers create a software prototype that they can share with users and get their feedback to make corrections and improvements before a lot of effort is spent building a fully functioning version. End users are much more helpful when they can see a prototype even if most of it doesn't actually work. The approach works well with the overlapping phases typical of iterative development, and it is often used in other software development approaches as well.
Discuss the testing phase of the systems development life cycle.
Testing goes on during the development phase, as individual modules are completed. When the system has been completed, it undergoes much more rigorous testing. Each test mimics events the system will handle when it goes live. The test cases are carefully documented so the developers can make corrections in case of any failures. Software tools help tremendously with this testing as well. Other software tools can check for security holes, compliance with accessibility regulations, performance under loads, broken web links, and more.
A disadvantage of custom system development is that it involves high overall cost and requires more time to go live.
