Product Requirements Document (PRD)
A comprehensive document detailing all functional and non-functional requirements, organized by priority and category.
Specification Capture
Specification capture that turns your product vision into requirements you can design and test against
I translate your product vision, user needs, and business requirements into precise engineering specifications, so the whole build starts on clear ground instead of costly guesswork.

Why it matters
Most projects fail on unclear requirements, not poor engineering.
The foundation of any successful electronic product begins with thorough specification capture. When requirements are unclear, incomplete, or misunderstood from the start, the result is scope creep and costly redesigns. A well-crafted specification prevents that, and it combines deep technical knowledge with practical industry experience to identify not just what the product should do, but how it should perform under real-world conditions, including manufacturing, testing, certification, and long-term reliability that might not be obvious at the outset. This is the start of taking a product from concept to production: turning a rough idea into a clear hardware specification and requirements set that the schematic, layout, and firmware can actually be built and tested against.
What you get
A specification package you can build and test to
Technical Specifications
Detailed electrical, mechanical, and environmental specifications with measurable acceptance criteria.
Standards Compliance Matrix
Identification of applicable standards (IEC, UL, FCC, CE, and others) and how each requirement addresses compliance.
Risk Assessment
Analysis of technical risks, potential failure modes, and mitigation strategies.
Interface Control Document
Definition of all external interfaces including connectors, communication protocols, and mechanical mounting.
Test Requirements
A preliminary test plan outlining how each requirement will be verified.
Budget and Timeline Estimates
Realistic cost and schedule projections based on the defined requirements.
Common problems avoided
The failures a clear specification heads off
Scope creep
Without clear requirements, features get added mid-project, causing delays and cost overruns.
Certification failures
Products designed without understanding regulatory requirements often fail EMC, safety, or environmental testing.
Manufacturing issues
Designs that work in the lab but cannot be reliably manufactured at scale.
Misaligned expectations
Stakeholders discover late in the project that the product does not meet their needs.
Integration problems
Interfaces between hardware, firmware, and mechanical components that do not work together.
Missing edge cases
Failure modes and operating conditions that were not considered during design.
How it works
A clear path from vision to signed-off spec
1
Discovery
I run an initial consultation to understand your product vision, target market, business constraints, and success criteria, reviewing any existing documentation, prototypes, or competitive products.
2
Requirements elicitation
I gather requirements systematically through interviews, questionnaires, and technical discussions, documenting each one with clear acceptance criteria.
3
Technical analysis
I review the requirements for feasibility, consistency, and completeness, and identify applicable standards, potential technical challenges, and risk areas.
4
Documentation
I create formal specification documents with clear organization, traceability, and version control. Every requirement is numbered and categorized for easy reference.
5
Review and validation
I run collaborative review sessions so all stakeholders agree on the requirements, refining based on feedback until the specification is approved.

Questions
Frequently asked
What is specification capture?
It is the step that turns a product idea and user needs into clear, testable engineering requirements before any design work starts.
Why pay for this instead of starting the design?
Most expensive redesigns come from unclear or missing requirements. A short, structured specification phase is far cheaper than discovering the gap after the first build.
What do you produce?
A written requirements document that covers function, interfaces, power, environment and constraints, clear enough to design and test against.
Can this lead into the full design?
Yes. Specification capture often runs straight into schematic, PCB and prototype work, so the requirements flow directly into the design.
Do you help take a product from concept to production?
Yes. Specification capture is the first step from concept to production: the rough idea becomes a documented hardware specification and requirements set, with the constraints, interfaces, and acceptance criteria written down so every later stage has something concrete to build and test against.
