Aerospace series - Programme management - Execution logic

Edition date: 2025-12-24
In Force
Available languages: English, French
Summary: The scope of the present document is to provide the elements needed for elaborating the programme execution logic and drafting the execution plan for the realization of a product. NOTE 1 In this document, the term “logic” alone is sometimes used for “execution logic”. NOTE 2 In this document, the term “product” is used to designate the object of the program concerned, and the term “system” is used to designate the product for anything related to system engineering. NOTE 3 The product is also considered a “system-of-interest” and its enabling systems are also taken into account. The execution logic and plan enable customers/suppliers to reach an agreement on how their respective processes and activities can be organized. The aim is to enable each actor in the programme to manage their activities with sufficient visibility of the sequencing of the other stakeholdersʼ activities. This document belongs to the documents supporting EN 9200 relating to the programme management specification. The present document describes the principles of programme execution logic and defines the corresponding management requirements. This description is supplemented: — on the one hand, in terms of execution logic principles, by: — the challenges of a basic logic common to all actors (synchronization); — the applicable criteria to set up this basic logic; — the translation of this logic into the programme processes; — on the other hand, in terms of implementing the execution logic, by: — the procedures for practical implementation of the management requirements defined in EN 9200; — adaptations of the logic according to the various constraints and specificities of the programme, and justification of these adaptations; — the consistency between the basic logic at system level and the logics at subsystem and constituent levels. The breakdown of clauses as used in this document gives a gradual understanding of the approach to be adopted to construct an execution logic. For instance: — Clause 5 presents the end-purpose of a programme execution logic as well as the associated basic concepts and the constituents of this logic; — Clause 6 describes and characterizes the process for building the logic; — Clause 7 concerns change control to the execution logic; — Clause 8 concentrates on the importance of capitalization and lessons learned. This document applies to aeronautical, space and defence programmes. The principles can be extended to other areas of activity. It applies to realization of a single product, of several samples or of a series. It applies to any customer/supplier level, while ensuring consistency between successive levels. The principles described concern all programme actors, from initial expression of need through to closure of the programme.

L’objectif du présent document est d’apporter les éléments nécessaires à l’élaboration de la logique de déroulement d’un programme et la rédaction du plan de déroulement en vue de la réalisation d’un produit. NOTE 1 Dans le présent document, le terme « logique » seul est parfois utilisé pour « logique de déroulement ». NOTE 2 Dans le présent document, le terme « produit » est utilisé pour désigner l’objet du programme concerné et le terme « système » est utilisé pour désigner le produit pour tout ce qui relève de l’ingénierie système. NOTE 3 Le produit est considéré également comme « système d’intérêt » et ses systèmes contributeurs sont également pris en compte. La logique et le plan de déroulement permettent aux clients/fournisseurs de s’accorder sur l’articulation de leurs processus et activités respectifs. L’objectif est de permettre à chaque acteur du programme de piloter ses activités en ayant une visibilité suffisante sur le déroulement des activités des autres parties prenantes. Le présent document fait partie des documents d'accompagnement de l’EN 9200 relative à la spécification de management de programme. Le présent document expose les principes de la logique de déroulement d'un programme et définit les exigences de management qui y sont associées. Cet exposé est complété : — d’une part, au niveau des principes de la logique de déroulement, par : — les enjeux d’une logique de base commune à tous les acteurs (synchronisation) ; — les critères applicables pour l’établissement de cette logique de base ; — la traduction de cette logique dans les processus du programme ; — d’autre part, au niveau de la mise en œuvre de la logique de déroulement, par : — les modalités de mise en œuvre pratique des exigences de management définies dans l'EN 9200 ; — les modulations de la logique en fonction de différentes contraintes et spécificités du programme et la justification de ces modulations ; — la cohérence entre la logique de base au niveau système et les logiques aux niveaux sous-systèmes et constituants. Le découpage des articles retenu dans ce document permet d'appréhender progressivement la démarche à adopter pour construire une logique de déroulement. À ce titre : — l’Article 5 présente la finalité d'une logique de déroulement de programme ainsi que les concepts de base associés et les éléments constitutifs de la logique ; — l’Article 6 décrit et caractérise le processus de construction de la logique ; — l’Article 7 concerne la maîtrise de l'évolution de la logique de déroulement ; — l’Article 8 insiste sur l'importance de la capitalisation et du retour d'expérience. Ce document est applicable aux programmes aéronautiques, spatiaux et de défense. Les principes peuvent s’étendre à d’autres domaines d’activité. Il est applicable aussi bien dans le cas de la réalisation d’un seul produit que dans le cas de la réalisation de plusieurs exemplaires ou d'une série. Il est applicable à tout niveau client/fournisseur tout en assurant la cohérence entre les niveaux successifs. Les principes exposés concernent tous les acteurs du programme depuis l’expression initiale du besoin jusqu’à la clôture du programme.
