IIBA® - International Requirements Definition and Change Request Management Training

Being independent of specific problem domains and solution technologies, and being language independent, this course is relevant to a wide range of enterprises, and roles within those enterprises, worldwide.

Relevant application sectors include defence, aerospace, telecommunications, public infrastructure, entertainment and medicine. Relevant organization types include military, public sector, contractors, product-oriented firms, consultants, research and development enterprises.

• It is expected that, on completion of the course, participants will:
• understand the principles of requirements engineering
• understand the role of requirements analysis (requirements capture and requirements validation) in achieving successful project outcomes
• understand the concept of requirements quality. Be able to measure the quality of a requirements specification, increasingly more accurately as skills in requirements analysis improve through on-the-job experience
• understand the basic types of requirements (functional, performance, external interface, environmental, resource, etc), and the significance of these distinctions. Be able to recognise requirements of each type, a prerequisite for effective specification writing
• be able to perform, at a basic level of skill at least, the techniques which collectively constitute an effective and efficient methodology for performing requirements analysis.
• have some basic capability to tailor the application of the techniques of requirements analysis to different scenarios
• be capable of extensive further on-the-job learning, within a sound conceptual framework, in the field of requirements analysis
• understand the role of specification writing in achieving successful project outcomes
• understand the principles of good specification structure, for specification of systems, software and services
• be familiar with the range of public domain standards for different types of requirements specifications.
