10 facts for identifying unmet non-functional requirements in IT projects.

To ensure customer satisfaction and high-quality systems, it is crucial to identify unmet non-functional requirements (NFRs) in IT projects. Here are ten essential facts to keep in mind when recognizing these often-overlooked requirements:

1. NFRs Are About System Qualities: Non-functional requirements typically refer to system attributes such as reliability, scalability, performance, security, and maintainability rather than specific behaviors.

2. Harder to Quantify: Unlike functional requirements, NFRs are often more challenging to quantify and measure, leading to them being overlooked or under-prioritized in the development process.

3. Impact on User Experience: Non-functional requirements (NFRs) can impact user experience, even if functional requirements are met.

4. Essential for System Viability: Even if a system meets all its functional requirements, failing to meet NFRs can render it unfit for its intended use or context, affecting its viability and success.

5. Crucial in Scaling and Growth: Inadequately addressed NFRs can become significant obstacles when scaling up an IT system. For example, systems not designed for scalability can face considerable challenges handling increased load.

6. Security is Often a Key NFR: Security is a critical NFR that needs to be focused. Unmet security requirements can lead to vulnerabilities and data breaches.

7. Can Be Elicited Late in Development: NFR is often the least cared for later in the development process, as they may not be as apparent as functional requirements during the initial stages.

8. Important for Compliance and Standards: Certain industries have specific NFRs related to compliance, standards, and regulations. Neglecting these can result in legal and financial repercussions.

9. Testing NFRs Requires Special Techniques: Testing for NFRs often requires methods different from functional testing, such as stress testing, load testing, security audits, and usability evaluations.

10. Documentation and Communication are Key: Proper documentation and regular communication about NFRs are essential to ensure they are understood, implemented, and tested appropriately throughout the project lifecycle.

By understanding and addressing these aspects of non-functional requirements, IT project teams can ensure the overall quality and success of the project. It's essential to give NFRs the same level of attention and rigor as functional requirements to avoid unpleasant outcomes.
