Systems Life Cycle
Analysis
-
the phase, by which, requires you to look at the alternative solutions that could be used to solve problems
-
-
Maintenance
After the system has been installed and is up and running, there will be a need to keep maintaining it
Over time, bugs will be discovered that weren't in the testing
-
Due to these bugs, larger changes could be made, meaning that parts of the system have to be altered
-
Investigation
To do this, you have to observe how the old system works and the issues that is caused by it
After that, you have to analyse it and formulate methods to solve and prevent this problems
-
Design
-
in this phase, the requirements specification and systems specification are written
-
-
Testing
During development, a test plan is made for testing
-
Implementation
When the system has been tested and is fully functional, it has to be installed so that the staff can use it
-
Evaluation
Once the system is finally running, it is essential to evaluate it
The two key questions
-
-
The questions are answered by considering details written down in the original Requirements Specification and comparing it to the performance of the new system
Introduction
At some stage, most businesses will need a new computerised system to assist them with day to day tasks
-
Feasibility study
In this stage, the company decides on whether a system is needed for them and if the expenses made will be equivalent to the benefits it may bring.
With that, the company will think of other alternatives that they could choose from, instead of using the new system.
