Software Development Process – Analysis

Today we started looking at the theory of the second unit of Higher Computing, Software Development, and started the stages of the software development process. There are 7 stages the you need to remember:

Analysis

Design

Implmentation

Testing

Documentation

Evaluation

Maintenance

The acrostic I offered to remember them by was:

A Dance In The Dark Every Monday

The one you guys came up with is unpublishable…

We also disucussed some of the people involved during analysis (client – who requests the software, Systems analyst – helps plan a piece of software based on the client’s needs), aswell as the document that is created then (the software specification).

Software Development Process – Design

Today we looked at the different methods that can be used to design your program. These include:

Flow Chart – A representation of the program showing the direction in which a user can proceed

Block diagram – A representation of the parts of the program in a diagram

Pseudocode – A version of the program written not quite in progrmaming code but not quite in normal English either

A/B Test Questions

The A/B test is on Thursday and I think it would be useful to do some more real exam type question practice. So have a go a the following (submit your answers by clicking on the comment link):
