Introduction
Requirements engineering is practised by many, mastered by surprisingly few. And yet, the payoff from achieving excellence in this field of project activity is large.
Requirements engineering may be considered to embrace:
- the recording (specification) of requirements, as requirements are first created;
- the capture of requirements not already recorded, and the validation of requirements which exist, whether or not they have been recorded, or have been recorded adequately (requirements analysis);
- the re-specification of requirements which have been inadequately specified;
- the maintenance of traceability between different expressions of the same requirement;
- the maintenance of traceability between requirements of different objects in design; and
- the management of the above activities.
This course first establishes fundamental principles and relationships as they relate to requirements (plus MOEs, etc), with emphasis on how requirements come into existence: the relationship between requirements and design.
The course then addresses the techniques used to capture, validate and gain a complete understanding of requirements, both initially, and at all subsequent stages of a system life cycle.
The course then addresses in detail the conversion of individual requirements into effective requirements specifications. The course focuses on the structure of requirements specification, based on principles and without reference to specific languages.
This course, available world-wide on an in-house basis, and in some countries on a public basis, is the language-independent equivalent of Project Performance International's 5-day public course in Requirements Analysis and Specification Writing (one day of this latter course focuses on English language requirements specification).
Training Objective
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; and
- be familiar with the range of public domain standards for different types of requirements specifications.
Who Should Attend?
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.
Requirements Engineering is designed for personnel who specify, perform, control or manage the development of small to large technology-based systems where successful outcomes are important. The course will be of particular value to people with job titles such as project manager, product manager, engineering manager, requirements manager, requirements engineer, specification writer, systems engineer, software systems engineer, software engineer, design engineer, test engineer, hardware engineer, and similar engineering and acquisition job titles.
Many other participants in the technical and management processes of transforming a need into an effective, technology-based solution will benefit from this course.
People whose primary interest is requirements expressed in the English language may prefer to take Project Performance International's companion 5-day course 'Requirements Analysis and Specification Writing', within which some hours are devoted to English language requirements specification constructs.
Training Method & Materials
The course is delivered in English using a mixture of formal presentation and an extensive set of individual/group workshops. Language support may be available for deliveries of the course in some countries - see country-specific course descriptions. The requirements analysis workshops carry a single system through a number of requirements analysis activities, simulating, as closely as possible, the conduct of a real requirements analysis. The specification writing workshops provide hands-on practice and guidance in structuring requirements specifications. Commendations on the high degree of effectiveness of this delivery approach are available on request.
Participants receive comprehensive course notes, two workbooks, each containing workshop exercises, numerous worked examples, a Requirements Engineering Resources CD-ROM, mainly in English, containing a wealth of valuable information (handbooks, templates, guides, papers, reports, standards, etc) and a variety of other reference materials and resources.
