Requirements Writing Training
Requirements writing requires a special skill set with a clear idea of the paradigm and objectives involved. For instance, a good requirement states something that is necessary, verifiable, and attainable. To be verifiable, the requirement must state something that can be verified by examination, analysis, test or demonstration. Statements that are subjective, or that contain subjective words, such as “easy,” are not verifiable.
One of the most important decisions in requirement writing is first being sure a requirement is even necessary. Some experts on the topic recommend asking yourself what is the worst thing that can happen without a particular requirement. If the answer is “nothing much,” then a requirement probably isn’t needed.
When a specific requirement is needed, it must also be attainable. To be attainable, the requirement must be technically feasible and fit within budget, schedule and other constraints. If you are uncertain about whether a requirement is technically feasible, a study may be required to determine its feasibility.
If what you want is not technically feasible or not within budget restraints, it’s no longer a requirement but rather a goal.
In requirements writing (as in good writing in general), authors should strive for clarity. Each requirement should express a single thought, be concise and simple. It is important that the requirement not be misunderstood — it must be unambiguous. Simple sentences will most often suffice for a good requirement.
Requirements Writing Training Course
The Tonex Requirements Writing Training Course addresses the techniques used to write, validate and verify requirements and convert them to technical design specifications. It gives attendees the basic tools necessary to write effective system design specifications. Requirements are the foundation for building systems and software. They determine WHAT the system must do and drive the system development. Requirements are used to determine if the project team built the system correctly. The requirements development process identifies the activities needed to produce a set of complete and verifiable requirements.
Participants learn how to:
- Write well-formed, validated requirements and specifications.
- Analyze, Verify and Validate requirements into a user requirements document.
- Create Project Plan/SEMP with various plans, such as the review plans, configuration management plans and risk plans.
- Establish Configuration management (CM) the process to control changes to the requirements and manage the baseline documentation.
- Plan the Risk management to monitor, control and mitigate high risk requirements.
- Manage Technical reviews to identify defects, conflicts, missing or unnecessary requirements.
- Manage Stakeholder involvement which is essential for validating the requirements. Are these the correct requirements?
- Establish Elicitation techniques to enable the discovery and understanding of the needed requirements.
- Manage Traceability of requirements to user needs and requirements, support documentation and constraining policies (e.g., safety requirements).
The systems engineering standard (EIA 632) defines “requirement” as “something that governs what, how well, and under what conditions a product will achieve a given purpose.” This course gives PEs 13 PDH (Professional Development Hours) approved by PIE.
Upon successful completion of the course, attendees will:
- Describe the way the system is intended to operate from the user’s perspective
- Describe Concept of Operations (ConOps) process where user needs, expectations, goals and objectives are described
- Understand how feasibility Study can produce the conceptual high-level design and requirements which can be used as a starting point for the project
- Demonstrate the ability to capture and validate requirements throughout the requirements analysis process
- Learn how to conduct technical reviews, manage stakeholder involvement and elicit requirements
- Understand traceability of requirements to user needs
- Understand the relationships among all stages of the system life cycle.
- Describe different levels of requirements
- Learn how to develop requirements, write and document requirements, check completeness of requirements, analyze, refine and decompose requirements, validate requirements and manage requirements
- Describe communications techniques to elicit requirements
- Classify requirements as functional or design
- Demonstrate the ability to write functionally oriented and design oriented specifications
- Understand how to convert requirements into valid design specifications
- Learn how to separate System and Sub-system Requirements
- Learn how to create a Verification Plan to verify each system requirement
- Effectively produce design specification
- Effectively perform Verification (Functional, Non-Functional and Interface reqs.) and Validation (ConOps)
