reqSuite® rm vs. Excel: When Is Excel Sufficient for Managing Requirements?

Brief Overview: Comparing Excel and reqSuite® rm

Microsoft Excel is a spreadsheet application. It was not originally developed for requirements management, but in practice it is often used for that purpose. The reasons are its widespread availability, ease of use, and high flexibility. Teams can define their own columns, assign requirement IDs, maintain status values, set priorities, and create reports. With Microsoft 365, Excel files can also be edited collaboratively, shared via OneDrive or SharePoint, and connected to other Microsoft services.

reqSuite® rm is a specialized requirements management tool. It was designed to capture, maintain, link, and manage requirements in a structured and traceable way throughout their entire lifecycle. The focus is not on spreadsheets but on a tailored requirements model, clear relationships, versioning, reuse, quality checks, reviews, impact analysis, and automated documentation.

The key difference is therefore not that Excel is "simple" and reqSuite® rm is "complex." The difference lies in their purpose: Excel is a general-purpose tool for tabular data.
‍reqSuite® rm is a specialized tool for requirements.

Similarities: What Both Tools Can Generally Do

At first glance, Excel and reqSuite® rm appear similar in some respects. Both tools allow requirements to be captured, sorted, filtered, and enriched with additional information. Status values, responsibilities, priorities, and categories can also be managed in both tools.

Typical similarities include:

These similarities explain why Excel is often used as an entry-level solution. If the goal is simply to collect, sort, and roughly prioritize requirements, Excel can be a suitable starting point. This is typically sufficient, especially in the early phases of a project or for smaller initiatives.

However, the differences become apparent as soon as requirements are no longer viewed merely as a list but as the foundation for development, coordination, traceability, and quality assurance.

‍

The Most Important Difference: List or Requirements Model?

Excel is based on rows and columns. Each requirement is typically represented as a row, while additional information is stored in columns. This approach is simple and flexible but only limited in terms of semantics. Excel does not know whether a row represents a stakeholder requirement, a system requirement, a module requirement, a test case, or a risk. It also does not know which relationships are necessary or even allowed from a methodological perspective. This logic must be maintained manually by the team.

reqSuite® rm, on the other hand, is based on a project-specific requirements model. This model defines which types of information exist, which attributes they have, and how they may be linked to one another. For example, a stakeholder requirement can serve as the starting point for system requirements. System requirements can then be refined into module requirements. Test cases can be linked to requirements to support later validation activities.

At first, this may sound more formal. However, it provides a key advantage: the tool understands the structure of the project. As a result, relationships become traceable, dependencies become visible, and errors are easier to identify.

With Excel, this structure depends largely on the discipline of the users. In reqSuite® rm, it is supported by the system itself.

Comparison of Excel and reqSuite® Based on Key Criteria

Where Excel Has Its Strengths

Excel certainly has legitimate use cases in requirements management. It would be wrong to claim that Excel is fundamentally unsuitable. In fact, Excel is very practical for certain tasks.

1. Fast Start Without Tool Implementation

Excel is already available in many organizations. It does not need to be purchased, implemented, or extensively explained. If a team needs to collect requirements on short notice, Excel is often the fastest option. A spreadsheet with columns for ID, description, priority, status, and owner can be created within minutes.

This is particularly helpful when it is still unclear whether a topic will be pursued further or when only a rough collection of requirements is needed.

2. High Degree of Structural Freedom

In Excel, users can add columns, insert formulas, apply filters, use colors, or create their own reports. This flexibility is a major advantage when requirements are still vague or when teams want to experiment with which information they actually need.

For small teams with clear communication, this flexibility can be very efficient.

3. Strong Reporting Capabilities

Excel is powerful when it comes to tables, filtering, pivot tables, calculations, and data analysis. Anyone who wants to analyze requirements by priority, status, source, or responsibility can often do so quickly in Excel. Power Query and data imports from various sources can also be useful when requirements or related information need to be consolidated from different systems.

4. Low Barrier to Entry for Participants

Many business departments, developers, project managers, and executives are already familiar with Excel. This lowers the barrier to adoption. Stakeholders who only occasionally review or comment on requirements often find Excel easier to use than specialized tools.

This advantage should not be underestimated. A tool that is technically perfect but not used by the people involved provides little value. Excel benefits significantly from its widespread familiarity.

‍

Where Excel Reaches Its Limits in Requirements Management

However, Excel's strengths can quickly become weaknesses when requirements need to be managed professionally rather than simply collected.

1. Lack of Semantic Relationships

In Excel, relationships between requirements can only be represented indirectly, for example, through ID columns such as "derived from," "affects component," or "verified by test case." This works as long as the structure remains small and manageable. However, once multiple levels of requirements, product structures, test cases, risks, or variants are introduced, things quickly become difficult to manage.

A typical problem is that one column contains a reference to another ID, but no one automatically checks whether that ID still exists, whether the relationship is valid, or whether a change affects additional requirements.

In reqSuite® rm, relationships are not merely text in a cell. They are actual links between elements. This makes it possible to analyze dependencies, validate relationships, and use them for impact analysis.

2. Versioning at the File Level Instead of the Requirement Level

Excel files can be versioned, especially when stored in SharePoint or OneDrive. This helps restore previous file versions or track changes made to a file. However, for professional requirements management, this is often not sufficient.

In practice, the challenge is rarely just finding an older file version. More important questions include: Which requirement was changed? What exactly was changed? Who made the change? Why was the change made? Which dependent requirements, tests, or documents are affected?

In Excel, these questions can only be answered through additional discipline, manual change logs, or complex workarounds. In reqSuite® rm, the history of individual elements is a core part of the system.

3. Data Quality Depends Heavily on User Discipline

Excel provides data validation, dropdown lists, and protected areas. Nevertheless, data quality still depends heavily on how carefully users maintain the spreadsheet. Columns may be used inconsistently, mandatory information may be omitted, terminology may vary, or multiple types of information may be mixed together in free-text fields.

reqSuite® rm uses defined attributes, input forms, mandatory fields, and project templates. This provides more guidance during data entry. It does not eliminate all errors, but it helps reduce many common inconsistencies.

4. Collaboration Becomes Difficult as Complexity Increases

Excel supports collaboration, particularly through Microsoft 365. Multiple people can work on the same file simultaneously. For simple spreadsheets, this is very useful. However, larger requirements repositories create new challenges.

When many people are simultaneously editing, commenting on, modifying, copying, or moving requirements, the risk of inconsistencies increases. Roles, responsibilities, approvals, and review processes can be defined organizationally, but Excel itself provides only limited support for enforcing them.

reqSuite® rm, in contrast, is designed for project-based collaboration. Roles, permissions, tasks, reviews, and structured coordination can take place directly within the requirements repository. This becomes particularly important when multiple departments, locations, or external partners are involved rather than just a small core team.

5. Traceability Quickly Becomes Confusing

Traceability is one of the primary reasons organizations move from Excel to a dedicated requirements management tool. As long as a requirement is represented by a single row, management appears straightforward. However, development projects rarely consist of isolated requirements.

A stakeholder requirement may lead to multiple system requirements. These are then broken down into modules or components. From there, tests, risks, decisions, change requests, or documentation obligations emerge. At the same time, requirements continue to evolve over time.

In theory, these relationships can be represented in Excel. In practice, however, this often results in multiple worksheets, ID columns, cross-references, and manual validation rules. The larger the project becomes, the harder it is to maintain an overview.

In reqSuite® rm, such relationships are part of the underlying data model. This makes it possible to identify gaps, track dependencies, and systematically analyze the impact of changes.

‍

When Excel Is Sufficient

Excel can be sufficient when requirements management is small in scope, relatively simple, and subject to few regulatory requirements. This is often the case when a team is managing only a limited number of requirements, requirements are not refined across multiple levels, and formal traceability is not required.

Excel can also be a sensible choice when requirements are collected only as a preliminary step before being transferred into another system later. Likewise, Excel can be useful for workshops, initial brainstorming activities, or simple prioritization exercises.

Typical situations in which Excel may be sufficient include:

However, this limit is often reached sooner than many teams initially expect. As soon as requirements become the authoritative basis for development, procurement, testing, approvals, or compliance activities, the demands placed on the tool increase significantly.

‍

When reqSuite® rm Is the Better Choice

reqSuite® rm is particularly useful when requirements are not only documented but actively managed. This applies especially to projects in which requirements need to be structured across multiple levels, linked to product elements, versioned, reviewed, and reused.

Typical situations in which reqSuite® rm is better suited include:

reqSuite® rm becomes particularly relevant once Excel is no longer used merely as a supporting tool but becomes the central repository for critical project knowledge. At that point, a spreadsheet can quickly turn into a risk: the file contains important information, but structure, traceability, and quality assurance are only partially safeguarded.

Typical Real-World Scenarios

Scenario 1: A Small Team Collects Requirements for an Internal Tool

A business department wants to improve an internal tool and collects 50 requirements. The requirements are prioritized, commented on, and then handed over to the IT department.

In this scenario, Excel may be sufficient. The scope is small, the number of stakeholders is manageable, and the requirements likely do not need to be traced across multiple levels. The key is simply to ensure that the spreadsheet is well organized and that responsibilities are clearly defined.

Scenario 2: A Product Development Team Works with Several Hundred Requirements

A development team manages requirements for a technical product. There are system requirements, module requirements, component requirements, and test cases. Changes to one requirement may affect multiple areas of the product.

In this situation, Excel quickly becomes risky. The number of relationships increases, changes must remain traceable, and consistency between requirements, product structure, and tests becomes critical. reqSuite® rm is significantly better suited for this type of scenario.

Scenario 3: Requirements Are Regularly Reused Across Customer Projects

A company develops similar products or systems for different customers. Many requirements are similar but need to be adapted for individual projects.

In Excel, reuse often results in copy-and-paste activities. This leads to duplicates, outdated text variants, and unclear differences between projects. reqSuite® rm can support reuse in a more structured way by allowing requirements to be selectively reused, compared, and further developed.

Scenario 4: Requirements Must Be Exported Regularly as Documents

Many companies work with structured requirements internally but still need to provide requirements as Word or Excel documents to customers, suppliers, or auditors. In Excel, document creation is often a manual process. Tables are copied, reformatted, extended, and later revised again.

reqSuite® rm can help because documents can be generated directly from the structured data repository. This reduces manual effort and lowers the risk that documents no longer reflect the current state of the project.

‍

Excel Is Often Not the Problem but the Symptom

Many companies say, "Our problem is Excel." Strictly speaking, however, that is usually not true. Excel is rarely the root cause. The real problem is often that requirements are managed without a clear structure, without defined responsibilities, and without sufficient traceability.

Excel merely makes these problems visible.

If requirements are poorly written, no tool can automatically fix that. If roles and responsibilities are unclear, even a specialized tool will not solve every problem. If nobody knows what information makes a good requirement, even the best software will have limited effectiveness.

The difference, however, is that a specialized tool such as reqSuite® rm can systematically support good practices. It can provide structure, make relationships visible, simplify reviews, and automate recurring tasks.

Excel, by contrast, offers a great deal of freedom. That freedom is often convenient at the beginning, but as complexity increases, it frequently becomes a burden.

‍

Why Companies Still Stay with Excel for So Long

Many teams know that Excel is not ideal. Nevertheless, they continue using it. There are understandable reasons for this.

First, Excel is already available. There appear to be no additional costs, no procurement process, no IT approval, and no training requirements. Second, Excel feels straightforward. Adding a new column is often faster than agreeing on a new data model. Third, companies initially avoid change by staying with Excel. Nobody has to introduce a new process or question existing ways of working.

These advantages are real in the short term. In the long term, however, they can become expensive. The costs do not arise from the Excel license itself but from manual coordination, search effort, inconsistent data, faulty copies, late changes, and a lack of transparency.

Therefore, the key question is not, "What does the tool cost?" The better question is, "What does it cost if requirements continue to be managed in an unstructured way?"

‍

Conclusion: Excel Is a Good Starting Point, but Rarely a Long-Term RM Solution

Excel is a powerful tool. However, once requirements become the authoritative basis for development, testing, procurement, documentation, or compliance, Excel is often no longer sufficient. At that point, traceability, versioning, structured relationships, change management, reviews, reuse, and quality assurance become essential.

reqSuite® rm was designed specifically for these tasks. It does not replace Excel because Excel is a bad tool. It replaces Excel where requirements need to be managed professionally.

Companies that still use Excel today do not need to change everything immediately. However, they should honestly assess whether Excel is still a helpful tool or whether it has already become a bottleneck. Conducting that assessment is often the first step toward better requirements management.

Would You Like to Find Out Whether Excel Is Still Sufficient for Your Requirements Management?

Then it is worth taking a closer look at your specific situation: How many requirements do you manage? How often do they change? How many people work with them? Do requirements need to be linked to tests, risks, product structures, or documents? And how much effort is currently spent on searching, coordinating, copying, and rework?

In a live demo of reqSuite® rm, we can show you what structured requirements management looks like in practice and when moving from Excel to a specialized requirements management tool becomes worthwhile.
