BCS Modelling Techniques
3 Days includes Exam
About the course
Using selected models from the Unified Modelling Language (UML), a standard for systems specification, this Systems Modelling Techniques course offers you a proven set of modelling techniques to use when specifying IT systems. Some of the areas we’ll cover include use case diagrams, analysis class diagrams and state machines. When combined with our Systems Development Essentials course, this module provides you with the core tools and techniques needed to become an effective systems analyst.
Who is it for?
The course is designed mainly for practising business analysts but is also suitable for others such as project managers and software engineers who wish to gain an insight into this aspect of the business analysis process.
There are no pre-requisites for this course.
During this three day course you’ll receive all the training you need to prepare for the BCS Systems Modelling Techniques certificate examination, which is held on the final afternoon of the course. Through a given business scenario, this open-book exam puts your knowledge of systems modelling and UML techniques to the test. A pass means you’re another step closer to achieving the BCS International Diploma in Business Analysis – the de facto certification for practicing business analysts. One last thing; this course is also a core module of the BCS International Diploma in Solutions Development, and is approved as consistent with the IIBA BABoK version 3.0.
This classroom-based course offers a comprehensive coverage of the tools and techniques that can be used to model, and thus specify an information system.
