European Norm



The purpose of this document is to provide effective support to any person or entity wishing to improve its effectiveness in its activities in the definition, development and/or the realization of any action or project.
Function Analysis involves and relies upon a way of thinking, based on a continuous process, with a dedicated team that encourages the search for the goal and the need to be fulfilled, before looking for ways to achieve it that applies at any level and in any process.
Function Analysis (FA) firstly, defines the objective in a concise and clearly expressed way, independent of any solution, and secondly, provides support and assistance in the process to effectively achieve the defined need. FA activities supports enhanced teamwork, assists in gaining a consensus agreement and collaboration in the collective pursuit of the chosen goal.
Function Analysis was linked to Value Analysis, Value Engineering and Value Management. Today Function Analysis has become a stand-alone method and is used by many disciplines such, for example, as concurrent or simultaneous engineering, systems engineering and risk management. The practice of Function Analysis shall meet specific requirements to ensure the validity of the expected results and ensure their use in the intended usage context. Function Analysis is a fundamental component in assisting in the optimum performance of organizations, allowing the pursuit of opportunities while identifying and significantly reducing threats throughout the life cycle and beyond.
This document separately establishes the process requirements applicable to deliverables expected from the Function Analysis. Firstly, Functional Need Analysis and secondly the Technical Function Analysis. The Technical Function Analysis (with the product related functions) has to endeavour to fulfil all the user related functions identified from the Functional Need Analysis.
0.2 Function Analysis at the heart of Management
For any management activity it is imperative to differentiate systematically the two distinct areas, in one area, the goal to be achieved (the objective), and in the other area, the way to achieve it (the means and resources, the process or the solution).
Function Analysis, with its two distinct areas, provides an effective and strong methodological support at any level and in any field, when dealing with challenges of whatever complexity. It could be used for example, in strategy planning, business and project management, product and market development, or in any process of problem solving. It provides you with the opportunity to improve the performance of your organization.
It is important to have in mind, for any project or action, that the quality of the result or answer will be at best as good as the question or the quality of the definition of the proposed action.
For example, Function Analysis is fundamental, in many ways a formal requirement of any Value Management approach, Value Analysis or Value Engineering action.
0.3 Contributions for the different users of the standard
The Function Analysis approach can assist the different users in clarifying, understanding and helping to define and resolve problems of any nature in an organization. Function Analysis assists in interrogating and challenging in two areas, firstly by clarifying the goal to be achieved and need to be met (Functional Need Analysis), and secondly, searching, researching and establishing the best solution to the identified need and goal (Technical Function Analysis).
The benefits from effectively applying Functional Need Analysis include:
- the identification or description, in a concise language, without any ambiguity, the need to be satisfied for a given study subject (the aim to be reached);
- the assurance of improved communication between everyone in the team involved in the project, within a common vision, free from unnecessary specialist jargon.
The benefits of the Technical Function [...]
