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.
At the end of this course you’ll not only have a good understanding of the models and methods used in system design, but you’ll also be able to apply them confidently to a multitude of project situations.
For that reason, this course is for all the system designers and software architects, including those working on system enhancements, who want to gain some hands-on knowledge of the best practice techniques to use when designing software solutions that meet business requirements. We’ll look at how requirements specified in a set of deliverables produced by business and system analysts can be achieved using models from the Unified Modeling Language (UML) and supported by more traditional approaches, like data normalisation. On top of that, the course will cover areas such as interface between analysis and design, logical process design and system controls and security.
Presented to you by one of the expert training consultants pictured below, each member of our Systems Design Techniques training team bring their substantial experience of software development and systems design to the programme.
To give you more of an idea of what you’ll learn and how the course will help you, here’s a quick guide to those three days.
- Design objectives and constraints
- Approaches to design
- Validating and using analysis models
- Input and output design, and user-interface design
- Introduction to components and software architecture
- Logical component architecture definition
- Component interface definition (services)
- Component engineering
- Logical data design and normalisation
- Rationalising relations and building TNF models
- Logical process design using structured English/pseudo-code
- Physical data design
- Physical process design
- System controls and security
Yes. During this three day course you’ll receive all the training you need to prepare for the BCS Systems Design Techniques certificate examination, which is held on the final afternoon of the course. 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.
At present, due to the Covid-19 crisis, the exam is not available in a classroom environment. However, for delegates attending a virtual or online course, the exam may be taken at a later date when restrictions have been lifted.
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.
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.
