Requirements definition
Clear, well-structured requirements are the foundation of successful project delivery. At RPS, we help clients define and manage requirements to align investment, minimise risk and support strategic outcomes. From early-stage scoping through to procurement and delivery, our approach ensures expectations are captured, documented and used to guide informed decision-making.
Defining success from the outset
Requirements definition is about more than documenting what a project must deliver. We work with clients to define functional, technical and business requirements that are specific, measurable and procurement-ready. This enables better planning, clearer evaluation criteria, and more predictable outcomes throughout the delivery lifecycle.
Our team supports projects across government, defence, infrastructure, and digital environments, providing structure and clarity for programs of all sizes and complexity.
Our services include
- Stakeholder engagement and requirements capture
- Functional and non-functional requirements documentation
- Prioritisation frameworks
- Procurement strategy and evaluation alignment
- Support and quality assurance
Supporting informed procurement and delivery
Well-defined requirements improve not only design and execution, but also procurement outcomes. RPS helps clients shape tender documentation, evaluation criteria and performance measures based on verified needs and aligned expectations.
Whether for systems acquisition, infrastructure delivery or organisational transformation, our support ensures that the project brief is consistent, testable and traceable throughout the lifecycle.
Reducing ambiguity, strengthening outcomes
Requirements definition is critical to reducing project risk. By resolving ambiguity early and engaging the right stakeholders at the right time, we help avoid rework, scope creep and misalignment later in delivery.
Our approach is built on collaboration, communication and structured facilitation, designed to uncover both expressed and unstated needs. Whether establishing requirements for a Defence capability, a precinct infrastructure upgrade or a complex digital system, we tailor the process to suit project scale, governance and regulatory context.
