Putting Software Development, Systems Analysis and Design etc.

into Context

Knowledge Required for System Construction

• Hardware– Hardware & Software Systems, Computer Networks, Client-

Server Systems

• Programming– VB, C++, Java

• Design– Human Computer Interface design

• Systems Analysis – Structured (SSAT module)– Object Orientated (OOM module)

• Other Uni modules?

Systems Design

• design print, screen and paper form layouts

• design file types and layouts

• specify processing required by computer

• specify processing required by people

• specify processing components and links

• specify system controls

• design a test plan

Systems Analysis

• analyse system requirements

• specify what the system must do

• decide on user training

• decide manual and computer components

• possibly decide on hardware and software required

• possibly oversee new systems construction

Analysis, Design and Construction

Objectives of a Business• Make profit/…./… and maximise profit/…/…

• How?– Re-design product/service?– Re-locate?– Target different customer base?– Take-over competitors?– Personnel re-structuring?– Improve procedures via information systems.

So………Software Development, Systems Analysis and Design etc are small building blocks – the PSAD module is to widen the

horizons!

Please ensure you do the independent study identified – it will be easier if done weekly

(there’s too much to cram it all in before each assessment)
