State the seven stages of the software development process
Analysis, Design, Implementation, Testing, Documentation & Evaluation
analysis stage
To get a clear understanding of the problem in terms of inputs, processes and outputs in order to provide the solution.
design stage
To planning the solution for example writing your pseudocode and creatring a wireframe
implementation stage
Turning the design into a set of computer instructions that the computer can understand; begin coding.
testing stage
To test that the program actually meets the specification; what the program is expected to do
documentation stage
the documentation which is to be distributed with the software is produced; how to use guide or technical installation guide etc
evaluation stage
Evaluation is reviewing the solution against a given criteria.
