BCS Systems Modelling Techniques - UML

In order to communicate system requirements clearly and accurately to both business and IT stakeholders, it is vital for analysts and designers to be able to construct models from a variety of perspectives. In most cases these models will provide the basis for more detailed design.

The starting point for this course is a set of requirements, as defined in the Systems Development Essentials course. It is primarily concerned with modelling systems using selected UML techniques. It requires delegates to construct different types of model reflecting different perspectives and to describe the interactions between them.

At the end of the course delegates may sit an examination to attain the BCS Certificate in Systems Modelling Techniques.

Following your exam you will be sent an email from BCS asking you to register for your exam. Once you have registered and your exam results become available then you will be able to log back into your account and view your results.

This course may be taken as part of the programme leading to the BCS Diploma in Systems Development.

Learning Objectives

At the end of this course you will be able to:

  • Justify the need for modelling and modelling techniques
  • Explain why it is important to model system requirements from different perspectives and identify specific modelling techniques
  • Construct a static structure model (class diagram) construct a process model (activity diagram)
  • Construct a simple dynamic event driven model (state machine diagram)
  • Evaluate how the various models reflect business objectives and system requirements (via critical success factors)
  • Appreciate how the various perspectives inter-relate to each other

Pre-Requisites

An understanding of the fundamentals of systems development, or attendance on Systems Development Essentials course.

Exams & Certification

Type of Exam: Written examination based on a business scenario

Supervised/Invigilated: Yes

Open Book: Yes

Pass Mark: 50%

Delivery: Paper based examination

If you are taking a BCS exam you must bring photographic identification with you (passport, driving license or student card), as it is a BCS requirement to produce it for the invigilator prior to the exam. Failure to produce a valid form of photographic identification will result in a candidate not being able to sit the exam. For any questions about what form of identification is acceptable please us.

BCS allow additional time for candidates who have a disability or whose native language differs to that of the examination paper. Full details are provided in the BCS Reasonable Adjustments Policy which is available to view on the BCS website. If you believe you qualify for this then please notify us as early as possible. At least two weeks' notice will be required for processing this request. Delegates failing to advise us and provide evidence when requested, may not be allowed the additional support offered via the BCS policy.
