BCS Systems Design Techniques

Business analysts, project managers, solution and systems developers and anyone who requires a practical understanding of the models and methods of systems design. Systems Design Techniques is also a Specialist Practitioner module on the BCS International Diploma in Solution Development.

Introduction

• Objectives and constraints of design
• The place of design in the systems development life cycle
• Using the products of analysis to drive systems design
• The work of the designer
• The scope of design
• Design methodologies
• Architectural issues in design
• Introduction to design patterns

User interface (UI) design

• Objectives of UI design
• Design of input and output interfaces
• Dialogue types
• Usability and style guides
• Prototyping the interface
• Modelling the user interface

Component-based design

• Introduction to components & software architectures
• Component design principles: cohesion, coupling, responsibility and reusability
• Using analysis models (use case diagram and class diagram) to create a logical component architecture
• Use case realisation with UML interaction diagrams
• Defining component interfaces
• Component engineering
• MVC (Model, View, Controller), choreography and orchestration design patterns

Logical data design (normalisation)

• Notation and conventions of relational data analysis (normalisation)
• Principles of progressive normalisation through first, second and third normal forms
• Rationalising results from normalisation of multiple data sources
• Building the normalised (Third Normal Form) data model
• Defining the final logical data design using Entity-Relationship Diagrams

Logical process design

• Activity Diagrams (UML)
• Structured English / pseudocode
• Data Navigation Diagrams

Physical design

• Optimising the logical design
• Principles of physical data design
• Principles of physical process design
• Design and architecture
• Packaging the design for delivery using Deployment Diagrams (UML)

System controls

• Risk in systems development
• Verification and validation of data
• Object controls
• Data controls & self-checking codes
• Function and state controls
• Visibility and encapsulation in object-oriented design (UML class diagrams)
• Audit trails
• Output controls
• Clerical controls
• Access controls, physical and logical security
• Backup and recovery
• Business continuity and disaster planning
• Legal requirements of the designer

One thing to bear in mind is that although you don’t necessarily need to have any existing knowledge in order to take this module, we do strongly recommend that, given the amount of technical material covered on the course, you have at least a basic understanding of the UML. And in particular, we suggest class models, use case models and interaction models (sequence diagrams). If you’re worried that you might not have the right basic knowledge, get in contact and we can see what options are available.

During this three day course you’ll receive all the training you need to prepare for the BCS Systems Design Techniques certificate examination. A pass in this module will contribute to the BCS International Diploma in Solution Development. Taking this course will also enable you to work towards SFIA skills DESN level 4 and DBDS level 3.

For delegates attending a virtual or online course, the exam may be taken at one of our examination sessions, either in London or in Thame. Please contact us for the available dates and to make a booking.

If this course is part of your BCS Diploma in Solution Development you have a choice of further modules which include the Core SD Diploma modules, Systems Modelling Techniques and Systems Development Essentials. Candidates who have already completed Systems Design Techniques will also need to pass one of the Knowledge-based Specialisms, including the Intermediate Certificate in Enterprise and Solutions architecture, the Foundation in Software Testing or the Foundation in Systems Development. The structure of the certification is shown here.
