Verifiable engineering requirements eliminate delivery risk
Kelvorina is an independent engineering requirements consultation desk in Denver, Colorado. Maria Ivanova transforms contradictory stakeholder briefs, interface control gaps, and unprovable tolerances into traceable, audit-ready technical baselines.
Specify.
Every ambiguous tolerance in an interface control document becomes an expensive dispute at acceptance.
Engineering delays rarely originate in physical machine shops or compiler faults. They stem from vague, untestable phrases like “reasonable latency” or “adequate thermal margin” pushed through procurement without verification formulas. When three external subcontractors interpret those adjectives independently, assembly lines stall at stage gates.
Kelvorina enforces structured syntax standards across every engineering requirement statement. We apply the Easy Approach to Requirements Syntax (EARS) and INCOSE technical guidelines. Every specification row contains an explicit trigger, a measurable system response, calibrated physical engineering units, and a mandatory acceptance test method.
Our hourly consultation rate is $150 to $250 per hour. We work in disciplined 55-minute milestone sessions designed to resolve twenty to fifty requirement lines or one contested boundary. Initial scope assessments are turned around in one to three working days.
Dissect.
Subsystem interfaces fail where neither vendor owns the wiring harness or signal envelope.
Interface Control Documents (ICDs) require formal arbitration when multi-vendor systems connect. When mechanical enclosures meet avionics control boards or industrial hydraulic manifolds, our review identifies orphaned tolerances, conflicting grounding paths, and missing pin-out definitions before purchase orders are issued.
Below is our signature drafting plate illustrating how multi-vendor interface requirements are dissected into mechanical, electrical, and protocol tolerances with bidirectional verification tags.
Operating Draw: 24 VDC @ 8.2 A nominal
Thermal Envelope: -40°C to +85°C
Ground Isolation: 1.5 kV galvanic
Verification: Test Bench Routine TB-04
Trace.
If a requirement cannot be traced to an inspection procedure or test record, it is a wish.
Requirements traceability is not an academic chore; it is the legal spine of your delivery contract. When a tier-one supplier claims delivery completion, the Verification Cross-Reference Matrix (VCRM) proves whether each specification line has been verified by Analysis, Inspection, Demonstration, or Test.
Bidirectional matrices link customer operational goals down through functional allocations and supplier specifications to individual test scripts.
Audit.
Fixed-bracket specifications audits pinpoint ambiguities before capital is committed to fabrication.
When a team inherits legacy documentation or prepares a major procurement package, an independent third-party audit detects hidden failure modes. Kelvorina conducts exhaustive requirements audits for $1,000 to $5,000 per project.
Our audit inspects every requirement against INCOSE quality characteristics: unambiguous syntax, singular intent, verifiable acceptance criteria, achievable tolerances, and bidirectional parentage. We produce a flagged defect ledger with suggested redlines in one to three days.

Requirements Scope & Audit Estimator
Adjust your project complexity metrics. The calculator applies Kelvorina confirmed pricing standards: audit price clamped between $1,000 and $5,000, 1 to 3 discovery sessions, and 1 to 3 days evaluation turnaround.
Verify.
Twelve capital projects delivered across medical hardware, industrial automation, and aerospace instrumentation.
Maria Ivanova has consulted on engineering and product requirements in Denver since 2018. Over that period, 12 completed projects with traceable requirements and sign-offs have reached stage-gate approval without contractual disputes over specification intent.
Proven templates, checklists, and documentation standards arrive ready for your team so you never start with an empty text document.
High-Altitude Environmental Enclosure
Structured 140 mechanical and thermal requirement lines across two external fabricators. Established bidirectional traceability to MIL-STD-810H vibration and thermal shock inspection protocols.
Multi-Axis Packaging Automation Cell
Authored 6 interface control documents reconciling mechanical safety interlocks, PLC fieldbus timings, and hydraulic actuator stroke tolerances for three competing equipment suppliers.
Fluidic Cartridge Handling Subsystem
Decomposed FDA design controls into verifiable EARS specifications. Eliminated 42 ambiguous assertions in legacy supplier specifications before initial pilot tool fabrication.
Resolve.
Straightforward answers to the practical concerns engineering managers raise before booking.
Requirements consultation is an operational investment. Here is exactly who this practice serves, what we refuse to do, and how our commercial engagement works.
Kelvorina does not write consumer software agile user stories or motivational roadmaps. We do not write statements like “as a user I feel delighted”. We do not accept projects where requirements cannot be tied to measurable physical units, verification procedures, or explicit acceptance tests. If your product does not have physical, electrical, or critical system interface constraints, our rigor will feel excessive.
Each 55-minute session is pre-scoped around one specific interface document or thirty to fifty requirement lines. We do not hold open-ended philosophical discussions. Maria Ivanova reviews the documentation in advance, chairs the review, flags contradictions in real time, and delivers clean, revised specification syntax within 24 hours of session close.
We work directly with engineering requirements templates, Excel/CSV traceability sheets, Jama Connect, IBM DOORS Next, Jira/Confluence system plugins, and plain Markdown repositories under Git version control. Our deliverables adhere strictly to your internal formatting standards.
The confirmed rate depends on interface complexity, the number of competing subcontractors involved, whether formal regulatory delivery dossiers are mandated, and whether physical on-site visits to Denver facilities or test benches are required. Standard remote reviews sit at $150/hr; high-consequence multi-contractor arbitrations sit at $250/hr.
Engage.
