What to Look for in a Requirements Management Tool

Requirements management has historically relied on documents, spreadsheets, emails, and other manual records of information. While these methods have served engineers well, they also introduce a significant risk of discrepancies, made worse by the fact that data handled this way quickly becomes obsolete.

As a result, engineers are now seeking simpler ways to manage product requirements, ensuring that design iterations are based on the most current and relevant information. However, engineering teams developing hardware products often struggle to make the switch to better systems. 

Although they can benefit from tools like Altium’s Requirements Portal, engineers frequently encounter an initial barrier: adoption. Moving away from manual, outdated information handling requires a purpose-built tool that supports this new, requirements‑driven approach without sacrificing control or visibility.

Key Takeaways

• Document‑based requirements management no longer scales for modern hardware product development. While documents and spreadsheets feel familiar and quick to adopt, they introduce serious risks such as version drift, unclear ownership, obsolete data, and poor traceability, leading to inefficiencies, design errors, and costly rework.
• The biggest barrier to better requirements tools is adoption, not value. Engineers hesitate to move away from familiar document-based processes, even though they recognize there’s a better way to work with requirements. Successful requirements management tools must support existing workflows while improving visibility and control.
• Effective requirements management demands live, bidirectional traceability. Modern RM tools must provide bidirectional traceability between requirements, design, and verification across ECAD, MCAD, and simulation. This real‑time linkage enables early verification, accurate impact analysis, and an always‑current source of truth.
• Automation, verification planning, and flexibility are essential for speed and compliance. Features such as reusable parameters, automations, AI‑assisted workflows, integrated verification management, and flexible import/export are critical to reducing design risk, supporting certification, and enabling fast iteration.

Why Organizations Still Handle Requirements Management in Documents and Spreadsheets

The decision to stick with documents and spreadsheets for requirements is rarely a strategic one; rather, it is a byproduct of the path of least resistance. These tools appear to be frictionless by “yesterday’s” standards. Companies are familiar with them, and there is a relatively shallow learning curve. 

Here is why engineers continue to use documents and spreadsheets: 

• Familiarity: While it may seem trivial to view familiarity as a cost to a design project, engineers who hold onto outdated workflows can become a significant operational hurdle. As projects demand their full attention, they may not consider how requirements are shared and accepted. Using Word documents or Excel spreadsheets allows them to act quickly and immediately, reinforcing reliance on these familiar tools.
• Ease of Use: Familiarity eliminates the need to learn a new system or deal with potential setup challenges. A centralized requirements system can only be effective if all users are able to integrate it into their existing workflows. For busy engineers, onboarding must be simple and unobtrusive.
• “Free” Tools: Engineers may assume that long‑used tools do not incur additional costs when sharing requirements. In reality, this perception can obscure the cost‑saving opportunities and efficiency gains offered by newer, more intuitive requirements management solutions.

The Risk of Document-Based Requirements Management

There are some variables that influence engineers to rethink their requirements management. These are either project-related aspects, such as version drift, ownership, and change history, or data-based factors like relevance, traceability, and verification procedures. 

Project Risk Factors

• Version Drift: An immediate danger of manual requirements management is the lack of a single source of truth. When requirements live in static documents or spreadsheets, they are often duplicated, shared, and saved locally. This is where human error creeps in. Version drift occurs when a requirement is changed in the latest specification, but the update does not reach all stakeholders because they work from static documents rather than a shared, continuously updated source.
• Requirements Ownership: In a document-based system, the lines of responsibility can quickly become blurred. Because spreadsheets are designed for general data entry rather than structured engineering workflows, they lack the granular permissions or assignment features found in dedicated RM tools. 
• Change History: A change history enables teams to track when a requirement was changed, by whom, why the change was made, and what its previous state was, providing a “git‑like” audit trail that is essential for formal audits and compliance.

Data Risk Factors

• Verification Status: Verification and testing against requirements are essential steps that allow engineers to move forward confidently. When verification is tightly linked to requirements, teams maintain a complete and accurate view of project progress and overall system readiness. If requirements and verification are disconnected, this visibility is lost, making it difficult to assess true project status and determine whether the system meets defined criteria for the next iteration. 
• Data Obsolescence: In a real‑time digital environment, any requirement exported to a static document or spreadsheet becomes outdated the moment it is downloaded. While static artifacts are sometimes required to meet regulatory and certification standards (such as ISO 13485 for medical devices or DO‑254 for aerospace), they represent snapshots in time, not living sources of truth. Relying on these static documents as a primary working method is inefficient and introduces risk, as teams may unknowingly base decisions on obsolete data. The same challenge appears in supply‑chain workflows, for example, when managing RoHS or REACH compliance information, where outdated documentation can lead to incorrect assumptions or compliance gaps.
• Traceability: Version control alone is not sufficient. Engineers must be able to question whether the information they are using is correct and current. Transparency is required to confirm that requirements remain valid and that design iterations remain aligned. While static formats may present information, engineers need confidence that all actions can be traced back to their originating requirements.

Attributes of a Good Requirements Management Tool

Bidirectional Traceability Links

A robust RM tool establishes a bidirectional "digital thread" between ECAD, MCAD, and simulation environments, creating a holistic link between subsystems and requirements. This chain serves as a source of truth necessary to align interdisciplinary teams. While static spreadsheets are capable of tracking these links, they are limited by their inability to track the design process in real time.

Verification Planning and Test Management

To avoid costly certification failures, testing must be an integrated part of the design process rather than a final hurdle. Effective RM tools bake verification planning directly into the functional requirements, guiding engineers in-situ to maintain compliance with standards like EMI or signal integrity. By aligning test management with live design data, teams can catch deviations early, ensuring the physical hardware accurately reflects its original requirements.

Version Control

Proper version control is more than just a label on a document. It is a means of “cleansing” data and avoiding “zombie” requirements. While engineers understand the basic purpose of version control, its real value lies in the intuitive links between requirements and the various stages of development that together ensure an accurate, up‑to‑date source of truth.

Smart Workflows and Automations

Reusable Parameters and Calculation Engine

Translation is a crucial component of a suitable RM tool. While requirements are provided in text format, engineers work in numbers; a gap to be filled with adequate communication. The ability to automate text-to-numbers proves valuable across multiple projects and provides a better understanding of the downstream effects of design. 

AI-Assisted Workflows

The best requirements tools are equipped with AI that engineers can leverage to simplify their updates. Large language models (LLMs) are highly proficient at dealing with text-based data and devising the best ways to format the data. This gives engineers a truly customizable experience while ensuring all updates are translated into a centralized source. 

Flexible Import and Export

The ability to import data into and export data from a centralized system is essential. Engineers do not necessarily need complex integrations or APIs, but they do need confidence that their tool can import and export requirements into alternative formats. This flexibility is often required at project handoff or when documentation is needed for certification purposes.
