Methodology

How Spec to Shelf guides are written

Last updated: November 2026 · Published by Cydney Mar

Every guide on Spec to Shelf is written by Cydney Mar from her stated experience, generally accepted product development practice, and named published sources.

This page explains where facts come from, how statistics are quoted, how options are compared, and how pages are kept current. Because the publisher offers product development consulting, the guides are not independent, and they say so where it matters.

How are recommendations formed?

  1. Publisher facts stay labeled

    Figures about Cydney Mar, such as 45+ years and $300M+ in sales, are presented as her own statements, never as an independent study.

  2. Published statistics are sourced

    Industry figures are quoted as published, with the full range and a link to the source.

  3. General practice is described as general

    Where no figure exists, answers describe what is generally true and say how to confirm the detail for your product.

  4. Comparisons use the same criteria

    Every option in a table is judged on the same columns, with the same kinds of facts.

  5. Nothing is invented

    No prices, reviews, ratings or claims are added that the publisher has not supplied or a source has not published.

  6. Pages show when they changed

    Each page shows a Last updated line, refreshed only when its content changes.

Common questions

Should I hire a product development firm or an independent consultant?

Consider a product development firm when you need a large team handling engineering, industrial design and testing in-house. An independent consultant fits founders who want one experienced guide across strategy, specifications, suppliers and launch. Compare both on the same points: scope, who owns the files, and experience in your category and channel.

Is a tech pack freelancer the same as a product development consultant?

Not quite. A tech pack freelancer typically produces the technical document for a style. A product development consultant may also cover strategy, supplier vetting, costing, production readiness and launch. If you already have suppliers and a plan, a freelancer may be enough; if not, broader guidance can help.

Can I develop a product myself without a consultant?

Yes, many founders do, using templates, software and supplier guidance. The risk is doing steps in the wrong order, such as sampling before the product is clearly defined or ignoring margins until it is too late, both mistakes Cydney Mar flags. A short expert review at key steps is a middle path.

Can my factory just develop the product for me?

Some factories offer development and full-package production, which can be fast. The trade-off is that specifications may live with the factory rather than with you, making it harder to compare quotes or move production later. Owning your tech pack or spec sheet keeps that choice yours.

Where do I start with a product idea?

Start with product clarity: write down exactly what you are making, who it is for, and why they would buy it, before spending on samples. That is step one of Cydney Mar’s Concept-to-Reality Pathway. Her free From Idea to Income workbook, offered on cydneymar.com, helps you score an idea and map a path to launch.
