Overview
This course is concerned with designing all aspects of the user interface (input forms, input screens, output screens, reports and documents, dialogues) as well as underlying principles of data and process design.
The process design approach is not prescribed but could include Structured English, Data Action Diagrams, Update Process Models, and Sequence Diagrams. Normalisation is the fundamental design technique for data design

Course Objectives
Upon successful completion of this course, delegates will be able to:

• Explain the role & objectives of systems design & implementation in the systems development lifecycle
• Produce effective input and output design
• Construct a usable user interface (HCI)
• Normalise a restricted set of inputs and outputs and produce a Third Normal Form data model
• Produce detailed specifications for selected update and read-only processes
• Understand and apply the principles of security, confidentiality and privacy
• Explain and apply the principles of physical design
• Define the role of testing in systems design
• Describe and evaluate different methods of implementation
• Define training needs and select an appropriate training method
• Describe a range of post-implementation issues

Optional Examination
An optional examination can be taken at the end of the course. The examination consists of 15 minutes reading time followed by a one-hour 'open book' written examination based upon a business scenario. The examination is charged for separately. Successful candidates are awarded the ISEB Certificate in Systems Design & Implementation Techniques
