Part 100: A guide for the application of the principles of configuration management.
5.2.3 Configuration Items designated by the customer
On the basis of criteria outlined above, a customer may designate the configuration items on which he estimates necessary to intervene directly (these items may have different names; in this document, they are called Ncustomer configuration items’). As soon as possible, this designation should be made and this designation, as well as the role that the customer intends to reserve for himself, should be implemented in the contract and more particularly in the Specification of Management.
NOTE The fact that a component of the product tree is designated as a customer configuration item does not impose that the higher level assembly of this item is a customer configuration item.
5.2.4 Configuration management authority and configuration management board
The setting up of the “programme configuration management is based on the responsible of the programme appointing a system level configuration management authority entitled to pronounce the decisions related to the configuration management of the system.
This authority is in charge of:
— validating organisation arrangements and processes proposed in response to the requirements of programmeH configuration management;
— selecting item and data;
— identifying as such the configuration baselines;
— taking decisions regarding technical changes and conformity discrepancies concerning system level;
— making sure of consistency and efficiency in the processing of technical changes and the nonconformities at each subordinate level;
— ensuring that the impacts of the decisions on contractual aspects are taken into account.
This authority may rely on a structure, sometimes referred as system configuration management boards.
Through a top-down delegation process, the configuration management of each configuration item is entrusted to a competent management authority invested with appropriate decision power.
The configuration item management authority is the lowest level of authority whose field of competence entirely includes the content of the item configuration.
Except opposite arrangements stipulated in his mandate, the field of competence of the configuration item management authority does not include interlaces with upper and adjacent items, and therefore Its external specifications (Technical Requirement Specifications/TRS).
5.3 ConfIguration management, during the life cycle processes
5.3.1 General
Configuration management is closely Integrated in all stakeholders involved In the programme and in the life cycle processes. The programme manager shall, in connection with the stakeholders, anticipate and look for the configuration management arrangements to be set up during the life cycle.
The configuration management plan of the relevant authority describes and specifies the organisation and related management rules.
For information purposes and to initialize the approach. AnncxA lays out a list of the main tasks of the configuration management.
5.3.2 ConfiguratIon Management, during the expression of need
At an agreed time in the need expression process the System Design Review (SDR) is carried out, that precedes the establishment of the functional configuration baseline (FBL). The system Configuration Management is then established.
5.3.3 Configuration Management during the preliminary design process
During the preliminary design process, the various skills supply data in order to:
— structure the system and identify the associated management authorities;
— select the configuration Items;
— select data that formalize the expression of need related to each configuration item:
— define the initial characteristics of possible solutions.
After the review and at the end of this preliminary design process, the Allocated Baseline (ABL) is
established.
5.3.4 Configuration management, during the detailed design process
During the detailed design process, the technical design (see RG.Aéro 000 14C) of each component (including these of configuration items) is – progressively and by iteration – built up.
Then, configuration management is based on the agreed allocated baseline configuration (ABL). Configuration management takes into account any changes affecting this baseline, in order to set up the design data/definition file.BS/EN 9223-100-2018 pdf download.
