FAQ

What work fits NAICS 541690?
  • Provide independent technical assessments of research methodologies, data quality, and experimental design for funded research efforts.
  • Develop risk assessments and mitigation plans for complex scientific programs or technical portfolios.
  • Define technical readiness criteria, test milestones, data-quality measures, and outcome indicators for science and technology portfolios.
  • Staff and support technical advisory panels, peer review panels, and expert consultant reviews for program decision cycles.
When is NAICS 541690 a weak fit?
  • Experimental research and development with sustained laboratory facilities and prototype development; missing the R&D and prototype fabrication element that places work under R&D NAICS.
  • Long-term systems engineering and integration that requires equipment procurement, installation, and lifecycle support; lacking procurement and integration deliverables moves scope out of this code.
  • Recurring accredited laboratory testing and certified analytical services that require laboratory accreditation and routine sample processing; this code excludes recurring laboratory certification obligations.
What solicitation language points to NAICS 541690?
  • Statement of work requests subject-matter expert deliverables such as white papers, technical recommendations, and short-term advisory reports with limited period of performance.
  • Labor categories list senior consultants, technical advisors, and subject-matter experts rather than engineering or bench-science technician positions.
  • Evaluation criteria emphasize quality of technical advice, past performance on advisory engagements, and proposed approach to assessments rather than prototype delivery or equipment procurement.
