Our Requirements Framework

Why are requirements important?

Requirements engineering is a process that defines a proposed system by identifying the needs and expectations of end users. The goal is to create an unambiguous, complete and consistent set of requirements that guide the development team. Requirements engineering is crucial for the success of a project, as getting the requirements right is the key to producing the desired outcome.

What is systems engineering?

Systems engineering is an interdisciplinary field of engineering that focuses on designing, integrating, and managing complex systems throughout their life cycle. It uses the V-model approach, which emphasizes verification and validation by aligning the analysis and synthesis activities to decompose and aggregate the user's needs into a system that meets their requirements.

Design Phase – Verification phase

Requirements Analysis: This phase contains detailed communication with the users of the system to understand their need and expectations. This stage is known as requirements gathering and discovery phase.

System Design: This phase contains the system design and the overall scope and planning phase of the system. This phase also starts includes the hi-level relationship of the product and develops system level roles and responsibilities.

Sub-system design: This phase is where system level components are broken down into sub-system level functional requirements. This phase also maps out the interfacing boundaries between sub-systems and traceability to the parent systems.

Module design: This phase is where the product is broken into small modules to enable the build phase to progress. It could include unit and component level specifications.

Requirements engineering vs project management?

Requirements engineering and project management are closely related, with requirements engineering being a key part of project initiation activities, such as recognizing and starting a new project. Requirements are used to create a plan for the project, which defines its scope and objectives, and are reviewed at each approval gate for consistency. These requirements are also used to determine the constraints that govern the planning and management of the project, including selection, acceptance, scheduling, scoping, and budgetary activities.

Requirements Compliance

Why requirements gathering is important?

Requirements gathering is important because it helps to identify the needs and expectations of the end users. It helps to understand what the user wants and how they want the system to work, what tasks they need to accomplish, and what flexibility might be required. It's also important to consider the impact of the project on existing systems and networks and to gather information about technological preferences and existing system integration, as it can have a significant impact on the development path and ultimately on performance and user task efficiency

Requirements Compliance

Reqi plays a crucial role in supporting projects and teams by providing a user-friendly platform for managing requirements and ensuring compliance. It allows teams to efficiently gather and manage requirements, by providing visualization tools to keep track of compliance and provide system-level views across the supply chain, and by promoting collaboration and aligning expectations by building deeper understanding upfront. It also helps to manage risk by tracking Assumptions, Constraints, and Dependencies throughout the project life cycle, and by ensuring that the requirements are well defined and managed, reducing the risk of errors, improving quality and reducing risk throughout the development, build, and testing phases. In this way, Reqi helps to ensure that the user's needs and expectations are met, and that the project is successful.

Typical process for gathering requirements include:

Use Case Scenarios: A use case is a document that describes how users interact with a system and accomplish tasks by outlining the steps they take, their goals and the system's response. It is written from the user's perspective and can include information about the user's role and their specific needs. In cases where the users are not clearly defined, personas can be created to represent different user types and their common behavior..
Mind Mapping: Mind mapping is a technique used to gather ideas and organize information by creating a visual diagram that shows the relationships among different pieces of information. It starts with a central concept, represented as an image or word in the center of a page, to which associated ideas are connected. Mind maps are a powerful tool for brainstorming, organizing information and identifying connections between ideas.
Brainstorming: Brainstorming is a group activity where participants and stakeholders come together to generate ideas and identify what is needed from a product. A facilitator leads the session, organizing and prioritising the group's responses. The objective is to generate as many ideas as possible and to sort and prioritize them later.

Testing Phase – Validation phase

Acceptance Testing: Testing performed by the End Users to verify that the services perform as expected in the Production Environment.

Readiness: Testing performed by the End User group or representatives to verify that the system user stories/services perform as expected before migrating to the Production environment.

System Integration testing: This is the overall testing that the integrated environment and any system integrations that have been implemented, performs as expected.

Inspections: the visual examination (possibly including physical manipulation or the use of simple mechanical or electrical measurement) of a non-executing work product to determine whether it meets its requirements.

Why requirements traceability is important

Requirements traceability is the process of tracking requirements throughout the product development lifecycle and it's important for several reasons. It's a common requirement for international standards and the management of safety-critical systems, it ensures that critical requirements are verified and that this verification is demonstrated through traceability. Traceability is particularly relevant when developing complex systems that have many interdependencies between different elements.

Traceability and Verification

Requirements traceability helps to ensure that all requirements are met and that they are verified through the design, development, and testing stages. It also helps to ensure that all artifacts associated with the requirements, such as models, analysis results, test cases, test procedures, test results, and documentation are tracked and can be traced back to the requirements. It also allows to trace people and user groups associated with the requirements.

Reqi plays a crucial role in managing requirements traceability by providing a user-friendly platform for managing requirements and ensuring compliance. It offers visualization tools to keep track of compliance and provide system-level views across the supply chain. It also supports collaboration and aligns expectations by building deeper understanding upfront, shifting from a reactive to a proactive approach. Furthermore, Reqi has a clean user interface and is designed to bring efficiencies and certainty to the asset lifecycle change by bringing the supply chain into one shared space. In addition, it helps to manage risk by tracking Assumptions, Constraints, and Dependencies throughout the project life cycle, and by providing a way to document, manage and share traceability information, allowing teams to track requirements throughout the product development lifecycle and align them with artifacts and user groups.
