BCS Systems Development Essentials with Agile

The Systems Development Essentials course is aimed at both existing and prospective systems developers as well as Business Analysts wishing to gain an overview of the issues and concepts involved in developing quality solutions in an Agile environment.

The course studies a number of systems development life cycles and the situations in which they are most appropriate before focusing in detail on an Agile approach.

Key areas include: examining how the systems development effort can be organised distinguishing between generic lifecycles exploring the DSDM Atern approach and roles looking at other Agile methods such as Scrum interpreting UML techniques, such as Use Case Diagrams and Class Diagrams considering other techniques that support iterative development, such as facilitated workshops, scenarios and hothousing.

This is an intensive three day course that places emphasis on the practical application of the analysis skills covered.

This course used to be called ISEB Systems Development Essentials

Learning Objectives

  • Identify the tasks and disciplines required for systems development and implementation
  • Investigate a system
  • Interpret business requirements and produce systems requirements
  • Quality assure the systems requirements documentation
  • Design test cases for the requirements
  • Describe the commonly-used development lifecycles defined in the syllabus
  • Describe in detail one methodology that embraces one (or more) of these lifecycles
  • Describe the structure and activities of this methodology
  • Describe, interpret and quality assure the key models that the selected methodology uses for defining the process, static and event perspectives of the system
  • Make effective use of different methods of interpersonal communications
  • Identify different architecture for systems development solutions
  • Conduct a system review
  • Explain how CASE tools might be used to support the method

Pre-Requisites

None, but the course assumes a basic knowledge of IT systems.
