Thinking Piece: The Importance of Non-Performance Standards in Project Development
Every cloud transformation project comes with its unique challenges and opportunities, but one usual pitfall is the focus on building features and functionality, often neglecting non-functional requirements (NFRs). While it's understandable to linger on what a project can achieve, the 'how'—the team's route, the constraints—remains equally crucial. Failing to pay adequate attention to NFRs can lead to stakeholder dissatisfaction as projects might miss targets in performance, security, scalability, and user experience.
To avoid this scenario, it's advisable to prioritize NFRs alongside functional requirements at the project onset. Here are some practical strategies to help identify and tackle NFRs early in the life cycle. However, before we dive into the methods, let's clarify the essence and significance of NFRs.
What Are NFRs, and Why Do They Matter?
NFRs refer to system qualities not covered by functional requirements, making sure a system performs well under real-world conditions. These factors may include response time, scalability, availability, security, reliability, and disaster recovery, while addressing maintenance schedules, user experience, or sustainability considerations like budget constraints and environmental impact. Proper NFR management requires aligning system performance and security with internal policies and external regulations. Balancing resource utilization with budget limitations is vital to making informed architectural decisions.
Balancing 'What' and 'How'
In many projects, development teams often fixate on addressing immediate concerns, emphasizing questions like "How are we going to build this?" or "What technologies should we use?" While tackling functional issues is essential, teams must not lose sight of how features perform under real-world scenarios. Falling into this trap can result in functioning but underperforming systems failing to meet user or business expectations in terms of performance, security, or reliability.
An additional implication of neglecting NFRs, especially long-term, is increased costs due to resource consumption, system failures, an inability to scale effectively, and downtime during peak traffic, leading to poor user experiences.
To circumvent these issues, it's essential to involve stakeholders early on, understand the broader business context, and shift focus from solely aiming for the project's end goal to discussing how the system should perform under various conditions. Balanced conversations involving both technical and non-technical teams can help define business goals, limitations, and operational priorities accordingly.
Emphasize Timing
Prioritize defining specific criteria at the outset and conduct regular reviews, such as quarterly check-ins, to ensure NFRs remain relevant and aligned with the organization's current objectives throughout the project lifecycle. Changes in business strategies, the incorporation of new stakeholders, or shifting priorities may necessitate a reevaluation and updating of NFR standards.
Conclusion
NFRs are instrumental to ensuring the success and efficiency of a cloud transformation project. They play a vital role in ensuring the system's reliability, performance, and service quality. By implementing best practices such as defining NFRs early in the project, conducting thorough analyses, prioritizing NFRs, using quantifiable metrics, implementing testing strategies, monitoring and adjusting, integrating FinOps, and communicating with stakeholders, organizations can not only identify and address NFRs effectively but also maintain business alignment and avoid costly oversights.

Travis Runty, as a project manager, recognized the importance of addressing non-functional requirements (NFRs) alongside functional requirements to ensure the success of cloud transformation projects. He emphasized the need to define and manage NFRs early in the project life cycle, as neglecting them could lead to increased costs due to resource consumption, system failures, and poor user experiences.
Unnecessarily focusing on project features and functionality at the expense of NFRs, as Travis pointed out, can result in projects missing targets in performance, security, scalability, and user experience, leading to stakeholder dissatisfaction. To circumvent this scenario, Travis and his team used practical strategies to identify and tackle NFRs, such as involving stakeholders early on, conducting regular reviews, and aligning system performance and security with internal policies and external regulations.
In light of this, Travis and the team defined NFRs, such as response time, scalability, availability, security, reliability, disaster recovery, maintenance schedules, user experience, and sustainability considerations like budget constraints and environmental impact, as system qualities not covered by functional requirements. Proper management of NFRs, according to Travis, is crucial to ensuring that the system performs well under real-world conditions and to making informed architectural decisions within budget limitations.
