Industries → clear SIN lanes (reduce scope mismatch).

The fastest way to avoid MAS rework is choosing a clean lane: scope language, labor categories, pricing tables, and evidence should all tell the same story. Use this mapper to translate your industry and service keywords into likely SIN “lanes” to validate in official sources.

Industry-to-SIN lane mapper

This tool is informational (not official). It helps you organize your “lane” so your narratives, labor categories, pricing, and evidence stay consistent. Use the result as a shortlist to validate in official scope references before you finalize your MAS offer or modification strategy.

Industry & service mapper
Pick an industry lane, then paste a short description. The mapper suggests likely SIN “lanes” to validate.

Inputs

Select an industry, then describe what you actually deliver (avoid vague marketing). Concrete verbs produce better results.

Tip: include deliverables (assessment report, implementation plan, monitoring, training) and who you serve (agencies, primes, contractors).

Suggested SIN lanes
Enter a description and click “Map lanes.”
These are not official SIN determinations. Use the shortlist to validate scope and tighten your story.
If you also sell to DoD or handle CUI, make sure your offering narrative aligns with your internal security posture (NIST / CMMC). If you want a quick review: contact FBP.

Industry checklists (keep one consistent story)

Regardless of industry, the same three failure modes create rework: scope mismatch, generic labor categories, and pricing contradictions. These checklists keep your submission consistent.

Scope & lane alignment ›
  • Use specific service verbs and deliverables (avoid “we do everything”).
  • Don’t mix unrelated work into one lane; split offerings cleanly.
  • Ensure your marketing language matches how you actually deliver (staff aug vs SOW vs managed).
  • Validate final SIN scope in official sources before you commit.
Labor categories (defensibility) ›
  • Duties must be concrete and not copy-paste across roles.
  • Minimum qualifications should match pricing level and seniority.
  • Titles should not imply scope you cannot evidence.
  • Keep a smaller set of strong roles rather than many generic ones.
Pricing logic (consistency) ›
  • One source of truth for rates; trace every number.
  • Apply escalation and discount assumptions consistently.
  • Ensure labor descriptions and rates match (no senior prices for junior duties).
  • Keep a simple change log so future mods don’t reintroduce contradictions.

FAQ

Is this an official SIN list? ›
No. This is a practical mapping tool to help you build a clean lane and reduce rework. Always validate SIN scope in official sources.
Why does the mapper return “lanes” instead of exact SIN numbers? ›
Because scope alignment is about what you actually deliver. The lane approach helps you tighten your story before you select exact SINs in official references.
