In interior design, what is best practice for specification writing?

• A. Use performance-based language, minimize brand bias, cite standards, include installation details and testing requirements, and align with project budget.
• B. Specify only brand-name products.
• C. Avoid citing standards to keep flexibility.
• D. Provide only aesthetic descriptions.

Answer: (A)

Best practice in interior design specification writing is to define what the project must achieve and how it will be verified, not to lock in a specific product. Use performance-based language to state required outcomes (like durability, fire resistance, acoustical performance, or finish tolerances) and attach acceptance criteria that are measurable. Minimize brand bias so suppliers can propose the best value while meeting the performance goals. Cite relevant standards and codes to ensure compatibility, safety, and quality across the project, and include installation details and testing or verification requirements so the work can be installed correctly and proven to meet expectations. Aligning these specifications with the project budget helps keep the scope realistic and prevents cost overruns.

Choosing brand-only requirements narrows options and can inflate costs or miss better solutions. Avoiding standards removes the performance and compliance guardrails that keep projects safe and interoperable. Providing only aesthetic descriptions fails to guide construction and verification, risking misinterpretation and performance gaps.
