Specification Development Process

JLN Engineers develops clear, concise, correct, and complete specifications that translate project needs and engineering decisions into documented requirements for services, products, materials, fabrication, installation, inspection, and testing, as applicable. Specifications establish performance criteria, technical requirements, and acceptance criteria, coordinated with drawings, calculations, and referenced standards. Review and revision control support consistency, traceability, and verification of the completed work.

  1. Define scope and intended use

    Identify the service, product, or work to be specified, its intended use, interfaces, and responsibilities.

  2. Gather requirements and references

    Collect client needs, design inputs, applicable requirements, and reference documents; record their sources and revisions.

  3. Establish performance and acceptance criteria

    Define performance, technical, inspection, and testing criteria that allow conformance to be evaluated.

  4. Draft specifications

    Organize requirements using consistent terminology and an appropriate specifying method; state each requirement in its intended location.

  5. Coordinate engineering documents

    Check specifications against drawings, calculations, and related documents; resolve conflicting, duplicate, and missing requirements.

  6. Review criteria satisfied?

    Review for clear, concise, correct, and complete requirements and coordination. Resolve findings before approval and issue.

  7. Approve and issue revision

    Obtain the required review and approval, identify the revision and issue purpose, and distribute the controlled documents.

  8. Evaluate feedback and changes

    Evaluate fabrication, installation, inspection, testing, and service feedback. Assess changes and return affected requirements and documents for coordination and review.

Clear
Use direct language and consistent terminology so the intended requirement can be understood without ambiguity.
Concise
Remove unnecessary wording while retaining the detail needed to communicate the requirement accurately.
Correct
Check technical accuracy, units, references, and agreement with the engineering basis and related documents.
Complete
Include the requirements, interfaces, responsibilities, and acceptance information needed for the defined scope.
