Requirement elicitation and analysis
Clarify stakeholder and technical needs, constraints and acceptance conditions. Review requirements for feasibility, consistency, quality and verifiability.
Capability
Systems & Requirements Engineering
Define what the system must do, how responsibilities are allocated and what evidence will demonstrate the result.
Systems and requirements work connects product intent to technical decisions. The scope can cover one unresolved requirement or interface, an architecture decision, or a connected system definition across hardware, software and verification.
When to involve CEVOLARION
- A requirement is open to conflicting hardware, software and test interpretations.
- A subsystem needs an architecture and an agreed allocation of functions before implementation can proceed.
- A baseline change affects several interfaces and the impact on downstream verification is unclear.
Engineering scope
The agreed assignment determines which activities are included and where the responsibility boundary sits.
Architecture and functional allocation
Develop system architecture and allocate functions to hardware, software and other system elements, with trade-offs and technical assumptions made explicit.
Decomposition and interfaces
Decompose system requirements into hardware and software requirements where applicable, and define the interfaces that connect the allocated work.
Traceability and verification
Connect system, hardware and software requirements to implementation and verification relationships, including gaps that need engineering decisions.
Feasibility and controlled change
Assess alternatives and requirement-change impacts, then maintain agreed baselines and decision records through lifecycle changes.
Interfaces to adjacent disciplines
Electronics & Hardware Engineering
Allocate hardware functions, constraints and interfaces that electronics development must satisfy.
Embedded Software & Platform Engineering
Translate system behaviour into software responsibilities and platform constraints.
Verification, Validation & Test
Agree how requirements will be tested and what evidence is needed for acceptance.
Example engineering outputs
Outputs are assignment-dependent and agreed for each engagement.
- Reviewed requirement sets and clarification decisions.
- Architecture views and functional allocations.
- Interface definitions and traceability structures.
- Trade-off findings, review records and change baselines.
Methods and engineering environment
- Requirement quality and verifiability review.
- Model-based systems engineering, including SysML or UML-related modelling where appropriate.
- Trade-off analysis, traceability and requirements change-impact analysis.
Where this discipline connects
Highlighted stages indicate typical connections. The actual entry point and scope follow the product and assignment.
Define
Clarify the problem, requirements and responsibility boundary.
Architect
Allocate functions and define system and discipline interfaces.
Develop
Implement electronics, platform and embedded software.
Integrate
Bring components, configurations and interfaces into a working baseline.
Verify & Qualify
Evaluate behaviour and assemble the agreed engineering evidence.
Release & Deploy
Prepare the release, production support and technical handover.
Evolve & Tailor
Maintain, adapt and control change across variants and product life.
Delivered at the scale of the work
This capability can contribute to specialist work, an Engineering Cell, a Defined Work Package or an agreed Managed Service. The collaboration model and partnership tier are separate decisions.
