Create a hierarchy of five of the most important topics you believe a one-day course titled "Performance Engineering: The Essentials Presented in One Day" should address. 2. Provide a detailed rationale for each of the five topics. Topics: 1. The role of performance requirements in performance engineering. 2. Qualitative and quantitative types of performance requirements. 3. Eliciting, writing, and managing performance requirements. 4. Scalability and performance. 5. Working with stakeholders to learn, influence, and tell the performance engineering story.

Introduction
Performance engineering is a critical discipline within software development that ensures systems meet desired performance criteria under expected workloads. A well-structured one-day training course titled "Performance Engineering: The Essentials Presented in One Day" must prioritize core topics that lay a solid foundation for both novices and practitioners. Selecting and understanding these topics allows engineers and stakeholders to collaborate effectively, optimize system performance, and address user expectations efficiently. This paper discusses a hierarchy of five essential topics, providing detailed rationales for their inclusion, forming a comprehensive outline for the course.
Hierarchy of Topics
The five critical topics, arranged to maximize learning impact within a single day, are:
1. The role of performance requirements in performance engineering
2. Qualitative and quantitative types of performance requirements
3. Eliciting, writing, and managing performance requirements
4. Scalability and performance
5. Working with stakeholders to learn, influence, and tell the performance engineering story
This ordering emphasizes foundational concepts first, progressing toward stakeholder engagement and real-world application.
1. The Role of Performance Requirements in Performance Engineering
Understanding performance requirements is fundamental to the success of any performance engineering effort. These requirements define clear, measurable objectives for system behavior under specified conditions, guiding design, development, and testing processes. Without well-defined requirements, efforts risk misaligned priorities, resource wastage, or failure to meet user expectations. The rationale for focusing on this topic early in the course is to establish a shared understanding among participants about what drives performance tuning and verification efforts. It also underscores that performance requirements are not arbitrary but strategic elements aligned with business goals and user satisfaction metrics (Jain, 2010).
2. Qualitative and Quantitative Types of Performance Requirements
Once the importance of performance requirements is established, clarifying their forms—qualitative and quantitative—is essential. Qualitative requirements describe performance characteristics in general terms—such as responsiveness or reliability—without specific metrics. Quantitative requirements specify measurable targets—such as maximum response time, throughput, or error rates. Recognizing these types enables engineers to craft precise, actionable performance criteria, facilitating effective testing and monitoring. This topic equips participants with the analytical tools necessary to translate high-level performance goals into concrete, testable statements (Bass et al., 2012).
3. Eliciting, Writing, and Managing Performance Requirements
The practical challenge in performance engineering lies in accurately eliciting stakeholder needs, translating them into well-formed requirements, and managing them throughout the development lifecycle. Effective elicitation involves stakeholder interviews, domain analysis, and iterative validation. Writing clear, achievable requirements prevents ambiguity and scope creep, while diligent management ensures requirements evolve with system changes. This topic is critical because poorly articulated or unmanaged requirements often lead to performance issues late in development or after deployment. Training in these skills improves communication, traceability, and accountability (Kotonya & Sommerland, 1998).
4. Scalability and Performance
Scalability—the system’s ability to handle increased loads—is a core aspect of performance engineering. An understanding of scalability principles helps evaluate whether systems can grow seamlessly or require redesigns. Topics include load testing, capacity planning, and architectural patterns that support scalability, such as horizontal scaling and caching strategies. Given that system demands often increase unexpectedly or over time, this module prepares participants to design systems that adapt efficiently, maintain performance, and optimize resource usage (Fowler, 2002).
5. Working with Stakeholders to Learn, Influence, and Tell the Performance Engineering Story
Effective performance engineering is not solely technical but also communicative. Engaging stakeholders—including business leaders, developers, and users—ensures performance considerations align with organizational goals. This topic emphasizes techniques to influence priorities, educate teams, and articulate performance findings compellingly. By mastering stakeholder communication, performance engineers can foster a shared understanding, support necessary investments, and embed performance into the organizational culture. This collaboration ultimately ensures that performance engineering is a continuous process rather than a one-time effort (Bertrand & Skovira, 2019).
Conclusion
In summary, this hierarchical selection of topics provides a comprehensive overview of performance engineering essentials within a one-day course. Starting with the role and types of performance requirements, progressing through elicitation and management, emphasizing scalability, and culminating in stakeholder engagement ensures a well-rounded learning experience. This structure enables participants to grasp core concepts rapidly, apply them practically, and foster collaboration, leading to more reliable, scalable, and user-centric systems.
