The Most Complete Guide to Requirements Management and Traceability
Why do projects in heavily regulated industries fail? Many researchers have investigated why systems and software projects fail. The Standish Group conducted research in 2009, which highlights that most reasons projects fail are related to requirements.
That is one of the main reasons why writing good requirements is crucial for project success. Additionally, writing good requirements brings many other benefits across teams.
Characteristics of Effective Software Requirements and Software Requirements Specifications (SRS)

What is Software Requirements Specification?
A Software Requirement Specification Document (SRS) is an essential document for software development that provides a detailed description of the needs and requirements of a particular project. It outlines the objectives, scope, background information, design details, implementation plan, and other related activities. The SRS document serves as a contract between the customer and developer to ensure that both parties understand the specifications and expectations of the product being developed. Additionally, it helps to reduce risks by ensuring that all stakeholders fully understand what is expected from them during each phase of the project.
A well-crafted SRS document should be complete, clear, and concise so that it can easily be understood by both developers and customers alike. Furthermore, having an SRS in place ensures that any changes or updates to the product during development can be easily documented and tracked. This helps to minimize confusion and ensures that the end product meets all of the requirements specified in the document. Overall, an SRS is a critical tool for successful software development projects. With proper use, it can help teams achieve quality results with minimal effort.
Rules for Writing Effective Software Requirements
According to INCOSE, there is a specific guide for writing great requirements. The characteristics include:
- Clear – The written requirements must be clear, easy to read, and understandable. Clearly specify the information that is exchanged between the actors using affirmative sentences. Every requirement must describe clear success criteria. Try to use simple vocabulary and avoid abbreviations. For example, “The user shall be able to view the Audit Log Report”.
- Atomic – Each requirement should describe a specific function or characteristic of the system. Conjunctions such as and, or, and so on should not be used because they might lead to missing out on relevant information and overlooking requirements. Splitting complicated needs into smaller parts till each one can be tested separately is one way to prevent this from happening.
- Unambiguous – Unclear, incomplete, or contradictory requirements can lead to errors and rework. To prevent this from happening, requirements should be reviewed by every stakeholder before they are finalized. This will help identify any gaps early on which can then be addressed.
- Verifiable – Each of the requirements should be analyzed and confirmed through techniques like inspection, analysis, demonstration, or testing. If a requirement is not verifiable it will become complicated to demonstrate objectively if it has been appropriately implemented.
- Necessary – Each requirement must document something that the users really need or something that is required to fulfill a standard or integration need due to the existence of an external interface. Also, it is important for each requirement to have an authorized source.
- Design Independent – Each requirement must define what is necessary, not how it will be implemented. The requirements must define the characteristics of the system that will be observed externally, not the internal details.
- Feasible – Each requirement must be technically executable and should be implemented taking into account the budget, deadline, and other restrictions that affect the project. The requirements should reflect the actual state of affairs, including cost, timeline, and technology. They shouldn’t be contingent on future technological advancements.
- Complete – Each requirement must be written in complete sentences, comprising a subject, verb, and complement. It must be easily understandable. Similarly, the requirements document should include enough information for your development team and testers to complete the product and ensure that it fulfills the user’s requirements without bugs.
- Correct – Requirements specified in the documents should be very precise to avoid any sort of confusion. They must not have any loopholes, ambiguities, subjectivity, superlatives, or comparisons. Hence, in order to write correct requirements, we must obtain correct information and correctly document the information that is gathered.
Characteristics Of An Effective Software Requirements Specification Document
There are certain rules that the requirements must adhere to in order to be called “Correct”.
- Complete – The requirements document should include enough information for your development team and testers to complete the product and ensure that it fulfills the user’s requirements without bugs.
- Consistency – Contradicting requirements MUST NOT be used. All the stated requirements must be compatible or else the system will not be able to fulfill them.
- Modifiability – Due to the fact that requirements could be altered at any point during a project’s timeline, it is critical for us to maintain a comprehensive log of all archived information, which would allow us to efficiently measure the impact of these changes on other related components.
- Prioritization – The requirements must be classified from the viewpoint of importance. Not all the characteristics desired for a system are equally important. For that, it would be helpful to establish a rule to define requirement priorities at the organizational level and adapt it to each project. And work with the users so that they can prioritize the requirements.
