Description

In the maintenance field, functional analysis helps clarify needs by focusing on the expected functions of a piece of equipment or service, rather than on predefined technical solutions. This approach encourages the development of solutions that are truly aligned with real operational requirements. The Functional Specification Document (FSD) formalizes this need expression and serves as a reference throughout the process of defining, improving, or replacing equipment—whether the work is done in-house or outsourced.

Training program

• Optimizing a Needs Expression Group
  • Fundamental concepts of the Functional Specification Document.
  • Reference to standard NFX 50-151.
  • Principles of functional analysis.
  • Differentiation between explicit and implicit needs.
  • Need expression focused on required functions, not on technical solutions.
  • Structured methodology for need formulation.
  • Scope of application of the method.
  • General approach to developing the Functional Specification Document.
  • Positioning of the FSD within the overall design or maintenance process.
  • Functional analysis of the need: System environment; Main functions, service functions, and constraints; Function characterization: criteria, performance levels, flexibility; Implementation methods.
  • Validation of the need expression.
  • Integration into a continuous improvement process
• Structuring and Writing the FSD
  • Standard structure of an FSD.
  • General presentation of the need.
  • Functional statement of expectations (main and service functions).
  • Identification of constraints (technical, regulatory, organizational, etc.).
  • Definition of the response framework (expected response format from suppliers or stakeholders).
  • Specification of any required technological solutions.
  • Document formatting and presentation.
• Implementing the FSD
  • Use the FSD as a communication tool between the requester (maintenance, operations...) and the supplier to clarify functional expectations.
  • Make the FSD a contractual reference to frame commitments, monitor deliverables, and validate results.
