One Platform to Manage Requirements Across Your Entire Supply Chain
Reqi is a requirements management platform that brings teams, suppliers, and stakeholders into one shared space. Define, track, and verify requirements with full traceability — from contract award through to acceptance. Built for regulated industries where getting requirements wrong is not an option.
The Problem With How Requirements Are Managed Today
Most organisations still manage requirements in spreadsheets, Word documents, and email threads. Information is scattered across disconnected tools with no single source of truth. The result is predictable: misaligned expectations, compliance gaps discovered too late, costly rework, and projects that blow past budget and schedule. When requirements live in static documents, nobody has real-time visibility — and that is when things go wrong.
of large infrastructure projects go over budget — with an average overrun of 28%. Poor requirements management is a leading contributor to scope creep, rework, and misalignment across the supply chain.
Defence & Aerospace: Where Ambiguous Requirements Put Lives at Risk
Defence and aerospace programmes operate under strict regulatory oversight with requirements flowing across multiple tiers of suppliers. A single misinterpreted requirement can cascade into system-level failures, safety incidents, or failed acceptance. With programmes routinely spanning decades and billions in investment, the cost of catching a requirements defect late is enormous.
The cost multiplier of fixing a requirements defect found during integration versus catching it in the requirements phase. INCOSE research shows that investing in early systems engineering delivers an ROI of up to 7:1 on total project cost.
Why this matters: Programmes like the F-35 Joint Strike Fighter — $183 billion over its original estimate, an 84% cost overrun — illustrate what happens when requirements changes cascade through deeply integrated systems across hundreds of suppliers. Structured traceability from the start is essential to managing this complexity.
How Reqi addresses this
- Full traceability from capability needs down to component specifications across every supplier tier
- Compliance visibility against standards like AS9100, MIL-STD-882, and DO-178C
- Audit-ready verification evidence tracked alongside each requirement
- Risk tracking for assumptions, constraints, and dependencies before they become programme-level issues
Key standards: DO-178C, DO-254, MIL-STD-882, AS9100, DEF STAN 00-56
Construction & Infrastructure: Stop Losing Requirements Between Design and Delivery
Large infrastructure projects involve hundreds of requirements spread across consultants, contractors, and subcontractors. Requirements evolve through design stages but often the supply chain works from outdated documents. When specification substitutions happen without proper traceability, the consequences can be catastrophic.
of construction rework incidents are caused by design inconsistencies or errors. Rework typically costs 5% of total project value and contributes to over half of all cost growth.
Why this matters: Research spanning 20 countries over 70 years shows 85% of construction projects experience cost overruns. The pattern is consistent — requirements scattered across static documents, with no single party holding the current baseline.
How Reqi addresses this
- Shared requirements baseline visible to every party — consultants, contractors, and subcontractors
- Capture assumptions and constraints early in design, before they become costly surprises during construction
- Track compliance against design standards and building regulations across the full supply chain
- Progressive acceptance workflows from procurement through to handover
Key standards: ISO 19650, ISO 9001, NEC4/FIDIC, CDM Regulations
Rail & Transport: Managing Safety-Critical Requirements Across Complex Programmes
Rail projects demand rigorous requirements traceability to satisfy safety assurance cases and regulatory approvals. With multiple interfacing systems and long programme timelines, keeping requirements aligned across signalling, rolling stock, and infrastructure teams is a constant challenge. When scope changes hit, every safety case and RAMS demonstration must be re-verified — creating cascading rework across systems integration.
average cost escalation on rail projects — significantly higher than other transport modes. Cost underestimation occurs in 86% of transport projects, driven largely by scope changes and interface complexity.
Why this matters: Projects like London's Crossrail — which grew from £14.8 billion to £18.9 billion and opened nearly four years late — show the cost of interface complexity and evolving requirements across multiple contractors. Bond Street station alone came in £570 million over its £110 million budget.
How Reqi addresses this
- Connect contract requirements with system architecture views across signalling, rolling stock, and infrastructure
- Trace from operational needs through to verification evidence across every interface and supplier
- Manage RAMS requirements (Reliability, Availability, Maintainability, Safety) with full traceability for EN 50126 compliance
- Track interface requirements across multiple contractors in one shared environment
Key standards: EN 50126 (RAMS), EN 50128, EN 50129, CSM-RA
Energy & Utilities: Compliance Traceability That Survives the Entire Asset Lifecycle
Energy and utilities projects span decades, with requirements that must remain traceable from initial specification through construction, commissioning, and operation. Regulatory compliance is non-negotiable. When design changes trigger re-verification across multiple safety classifications, teams without structured traceability lose weeks chasing documentation.
Projects like Plant Vogtle (USA) — which nearly tripled in cost from $14 billion to $36.8 billion and delivered over seven years late — highlight what happens when thousands of safety-critical requirements interact across dozens of specialist suppliers without structured traceability.
Why this matters: Nuclear and energy projects require complete traceability from safety case through to as-built configuration. Any design change triggers re-verification across multiple safety classifications. Utilities often lack the in-house depth to manage these requirements across dozens of specialist suppliers simultaneously.
How Reqi addresses this
- Full lifecycle traceability from specification through construction, commissioning, and operation
- Track assumptions, dependencies, and acceptance criteria across every project stage
- Supply chain collaboration so asset owners and specialist contractors work from the same baseline
- Maintain complete requirement history — nothing is lost when teams or phases change
Key standards: IEC 61508, IEC 61513, ISO 55001, NERC CIP
Mining & Resources: Bringing Rigour to Requirements in Remote, High-Risk Environments
Mining and resources projects operate in demanding environments where equipment specifications, safety requirements, and environmental obligations must be met precisely. Requirements are often managed informally, with critical details buried in contract annexures that suppliers never fully review. Inadequate front-end engineering cascades through procurement, construction, and commissioning.
of large capital mining projects come in late and over budget — by an average of 43%. Poor front-end definition and unstructured requirements are consistently identified as root causes.
Why this matters: Cost overruns of 25–60% in mining capital projects are consistently rooted in inadequate FEED (Front-End Engineering Design) — poorly defined specifications and scope changes during execution. Organisational process failures appear in 65% of safety incidents.
How Reqi addresses this
- Structure supply chain requirements so every party knows what is expected and what evidence is needed
- Surface risks — assumptions, constraints, and dependencies — before mobilisation, not after
- Track environmental and safety obligations alongside technical specifications
- Give remote project teams real-time visibility of compliance status across every contractor
Key standards: ISO 45001, ISO 14001, JORC Code, IFC Performance Standards
Healthcare & Medical Devices: Requirement Tracking That Meets Regulatory Scrutiny
Medical device development demands complete traceability from user needs through design inputs, risk controls, and verification records. Regulatory submissions require evidence that every requirement has been addressed and validated. A missing trace link can trigger a recall affecting hundreds of thousands of devices in the field.
Software design errors are the most common root cause of FDA medical device recalls. 46% of software-related recalls are caused by user interface errors alone — requirements that were poorly defined, not traced, or never verified.
Why this matters: IEC 62304 requires traceability from hazardous situations through software items to risk control measures and their verification. When a software update changes behaviour, the entire traceability chain must be re-verified across all safety classes. A single missing trace link can trigger a Class I recall.
How Reqi addresses this
- Structured requirement tracking from user needs through design inputs to verification evidence
- Multi-party acceptance workflows for design reviews and regulatory submissions
- Manage risk items — assumptions, constraints, and dependencies — alongside design requirements
- Clear traceability that auditors and regulatory bodies can follow without chasing documents
Key standards: IEC 62304, ISO 14971, ISO 13485, FDA 21 CFR Part 820, EU MDR 2017/745
Manufacturing & Automotive: Aligning Specifications Across a Tiered Supply Chain
Automotive and manufacturing supply chains are deep and fast-moving. Specifications flow from OEMs through tier-one and tier-two suppliers, and a misaligned requirement at any level creates quality escapes, recalls, or production delays. As vehicles become software-defined, a single component interacts with multiple systems — making requirements coordination across the supply chain more critical than ever.
The automotive industry spent approximately $22 billion on recall-related costs in a single year (2016). Supplier share of recall costs has tripled from 5–7% to 15–20%, reflecting supply chain requirements coordination failures.
Why this matters: Electronics-related recall issues have surged roughly 30% annually since 2013. As systems become more integrated, a design defect in one supplier's component can cascade across millions of vehicles — making traceable requirements across every tier non-negotiable.
How Reqi addresses this
- Give every supplier tier visibility of allocated requirements with compliance tracking that rolls up to system level
- Manage functional safety requirements (ISO 26262) alongside production quality (IATF 16949)
- Capture supplier responses and track acceptance from design through to production
- Maintain a single source of truth across OEMs, tier-one, and tier-two suppliers
Key standards: ISO 26262, IATF 16949, Automotive SPICE, UNECE WP.29
IT & Telecommunications: Managing Requirements When Systems Never Stop Changing
Telecommunications and IT infrastructure projects involve rapidly evolving requirements across multiple vendors and integration partners. Scope changes are constant, and without structured requirement tracking, teams lose sight of what was agreed versus what is being delivered. The stakes are high — and the failure rate reflects it.
Large IT projects (over $15M budget) run 45% over budget and 7% over time, while delivering 56% less value than predicted. 66% of organisations report frequent project delays caused by unclear requirements.
Why this matters: One in six IT projects experiences a cost overrun of 200% or more. Public-sector IT projects overrun schedules 81% of the time. The root cause is almost always the same — requirements that were unclear, untracked, or lost between contract and delivery.
How Reqi addresses this
- Capture baselines and track modifications as requirements evolve through delivery
- Maintain traceability across multiple vendors and integration partners in one platform
- Real-time compliance visibility so nothing is lost between contract and delivery
- System architecture views to manage interface requirements across complex multi-vendor environments
Key standards: ISO/IEC 27001, ISO/IEC 20000, TOGAF, SOC 2, TL 9000
