Although the product manager is usually accountable for curating and defining requirements, stakeholders from various departments, including customers, partners, sales, support, management, engineering, operations, and product team members, can also generate requirements. Effective communication is crucial to ensure the engineering team comprehends shifting priorities and any changes in requirements.

Benefits of requirements management
Requirements management offers several benefits, such as reducing the cost of development across the product lifecycle, minimizing defects, mitigating risks for safety-critical products, accelerating delivery, enabling reusability, ensuring traceability, and linking requirements to test cases. Additionally, global configuration management allows for better control over product variations across different markets, reducing the risk of noncompliance and ensuring regulatory requirements are met.
A plan for requirements management (RMP) is essential to manage, document, analyze and track all the requirements in a project. This plan covers everything from initial information gathering to detailed product requirements that may be collected throughout the project’s lifecycle. Key aspects of an RMP include project overview, requirements gathering process, roles and responsibilities, tools, and traceability.
To manage requirements, there are several features to look for in a requirements management tool. The process typically follows the systems engineering V model, consisting of steps such as collecting initial requirements, analyzing them, defining and recording them, prioritizing them, agreeing on and approving them, tracing them to work items, and utilizing test management to verify and validate system requirements. The impact of changes is assessed, and requirements are revised and documented.
The complexity of developing smart connected products can be harnessed through a well-executed requirements management process. Utilizing a requirements management solution streamlines the process and optimizes speed to market while improving quality.
Digital requirements management is an effective way to capture, trace, analyze, and manage requirement changes. It ensures changes are tracked securely in a central location and enhances collaboration between team members. Increased transparency minimizes duplicate work and improves agility while ensuring compliance with standards.
For a requirement to be considered “good,” it should possess specific characteristics such as being testable, clear, concise, accurate, understandable, feasible and realistic, and necessary. Sets of requirements should be evaluated to ensure they are consistent and nonredundant.
The design and development of products are being transformed by the Internet of Things (IoT), which is revolutionizing not only their functionality but also their complexity. With additional software and lines of code, products are becoming more intricate, allowing for greater connectivity. However, requirements management can help overcome the complexity and interdependencies that exist in modern engineering lifecycles. It streamlines product development and speeds up deployment.
Inadequately defined requirements are frequently cited as significant reasons for project failures. Scope creep, project delays, cost overruns, and subpar product quality that fails to meet customer needs and safety requirements are all possible outcomes of insufficiently defined requirements.
To ensure project success, having a requirements management plan is crucial. Such a plan allows engineering teams to control the scope and manage the product development lifecycle effectively. Requirements management software provides the necessary tools to execute the plan, resulting in reduced costs, faster time to market, and improved quality control.
Requirements management aims to achieve the successful completion of product development goals. It encompasses a range of techniques, including documentation, analysis, prioritization, and agreement on requirements. Its objective is to ensure that engineering teams have access to current and approved requirements, which helps prevent errors. Requirements management facilitates effective communication with stakeholders, from the beginning of a project to its end, throughout the engineering lifecycle. By keeping track of changes in requirements and fostering communication, requirements management helps ensure project success.
