Systems Design Techniques (ISEB Certificate In Systems Design
Techniques Exam Option)

Product Description

Overview

In order to deliver solutions that meet business users? demands, it is essential that systems development professionals thoroughly specify all aspects of the system design. They also need to ensure that the optimum testing & implementation strategy is adopted.
This class focuses on those design & implementation issues. It is concerned with designing all aspects of the user interface (input forms, input screens, output screens, reports & documents) as well as the underlying principles of data & process design. It also addresses areas that must not be neglected before, during & after implementation.
At the end of the class delegates may sit an examination to attain the ISEB Certificate in Systems Design Techniques. (These delegates should also book on class code SDTEX). This class may be taken as part of the QA programme leading to the ISEB Diploma in Solutions Development.
This is an intensive four day class that places emphasis on the practical application of the techniques covered. Delegates participate in exercises, & case study tasks.
Those delegates taking the ISEB certificates will need to spend 60-90 minutes each evening on revision & example examination questions.
Systems design techniques examination
The recommended combination & sequence of classs for delegates wishing to complete QAs programme leading to the ISEB Solutions Development Diploma is (1) Systems Development Essentials, (2) either Systems Modelling Techniques (UML) or Systems Modelling Techniques (Structured), (3) Systems Design Techniques, (4) Software Testing Foundation.
