Verify.

Twelve completed capital projects have reached stage-gate sign-off under these verification matrices.

Engineering programs stall when interface specifications and acceptance criteria are left unverified until fabrication. Since 2018, Maria Ivanova has directed requirements consultation and audit mandates across complex hardware assemblies, automated industrial equipment, and regulated instrumentation. Every project record below represents an audit-ready baseline with bidirectional traceability from primary user needs down to physical test procedures.

Our engagements operate under verified commercial terms: $150–250 / hour for focused engineering and system requirements consultation, or $1,000–5,000 / project for an independent specifications audit. Initial evaluation turnaround takes one to three days.

Cleanroom Verification Sign-off

Compare.

How Kelvorina evaluates and structures specifications against standard agency practices.

When evaluating engineering requirements support, technical teams look at five tangible criteria: experience in physical engineering requirements, competence in product requirements, preparation turnaround, documentation depth, and the presence of proven templates with bidirectional traceability.

Evaluation Criterion	Kelvorina Practice Standard	Generic Software / Strategy Agency
Engineering Requirements	Physics-bound tolerances, EARS syntax, environmental constraints, mechanical interfaces	Vague agile user stories lacking physical units or mechanical context
Product Requirements	System boundaries mapped directly to acceptance inspection procedures	Subjective feature wishlists without verification methods
Turnaround Speed	Initial scope evaluation prepared in 1–3 business days	3 to 6 weeks of scoping committees and discovery overhead
Documentation Depth	Full ICD registers, verification matrices, and clause-by-clause ambiguity audits	Slide decks, high-level process maps, and informal sprint tickets
Traceability & Tooling	Bidirectional matrices linking each requirement to bench tests, hardbound templates	No formal traceability; manual spreadsheets with disconnected rows
Commercial Rates	Transparent: $150–250 / hr, project audits at $1,000–5,000	Hidden retainer minimums, ballooning change orders

Request Evaluation (1–3 Days) Review Scoping Determinants

Engage.

Step-by-step engagement workflow for new requirements reviews and audits.

We keep engagements focused and predictable. A standard working session lasts 55 minutes and resolves one interface boundary or fifty requirement lines. Most scoping evaluations are completed in 1 to 3 discovery sessions.

Intake Review: You submit your requirements register, interface notes, or vendor contract via our Denver office desk.
Scope Evaluation (1–3 Days): We analyze clause volume, interface count, and revision depth to produce a transparent fixed audit quote ($1,000–5,000) or hourly schedule ($150–250/hr).
Working Sessions: Structured 55-minute sessions dedicated to resolving specific ambiguities, EARS syntax drafting, and boundary alignment.
Stage-Gate Sign-off: Delivery of complete bidirectional traceability matrices, approval checklists, and verification documentation.

Who this is not for: We do not write marketing copy, and we do not produce quick agile user stories for consumer smartphone apps. Our work is built for hardware engineering, physical systems, and capital procurement where errors carry genuine financial consequence.
