1                                 General

1.1                           Introduction

Configuration Management (CM) provides a key discipline in the through-life management of defence materiel.  It is the cornerstone of aircraft and equipment management safety, ensuring that the various parts of a complete product or system, including spares, test equipment, tools, ancillaries, software and support documentation, remain compatible.  Configuration baselines are established and materiel is verified against its baseline to ensure conformity.  CM with regard to airworthiness is described within JSP 553.

43

1.2                           Applicability

The principles of configuration management are to be applied to defence materiel by all Services, authorities, organizations and agencies responsible for its custody or management.

2                                 Policy on the use of Configuration Management (CM)

Integrated Project Teams (IPTs) are to have a Configuration Management Plan (CMP) in place for all items of materiel that may be subject to modification.  Where a CMP is not in place, it is to be introduced unless, due to imminent obsolescence or out of service date, to do so would involve nugatory effort.

Note:

A commodity IPT is to have a CMP for major equipments and/or equipment ranges that may be subject to modification.  Platform IPTs are to have a CMP for each Mark or type of equipment for which they hold responsibility.  The relationship between a platform and its commodities is to be recorded in the platform Support Policy Statement in the Topic 2(N/A/R)1 and in Internal Business Agreements, where appropriate.

IPTs are to establish control of CM through the formation of a management group, such as a Configuration Control Board, to ensure that prescribed CM systems are introduced and applied.

3                                 CM and planning

3.1                           Guidance on CM

To assist IPTs in planning and implementing CM, 4the Acquisition Operating Framework website provides governing policy that outlines the CM principles to be applied by IPTs, and their suppliers, to ensure that equipment delivered to the user fully satisfies physical and functional performance characteristics.  Def Stan 05-57 (CM of Defence Materiel) provides the CM requirements that are to be invoked in contracts.3  CM with regard to airworthiness is covered in JSP 553, Chap 5 – Implementation of Design Changes.

3.2                           Configuration Management Plan (CMP) requirements

As a minimum, a CMP is to:

1            Be documented.

2            Show the configuration of an item at any time in its life cycle.

3            Provide a means for managing modifications.

4            Involve the principle CM activities of planning, documenting, controlling, accounting for and auditing the item’s configuration.

3.3                           CMP content

The CMP is used to define how the CM requirements of an item, both hardware and software, are to be managed throughout the life cycle of the item.  The CMP is to address, but not be limited to:

1            Purpose, scope and programme.

2            Organization structures, committees and responsibilities.

3            Configuration change management procedures.

4            Change control of the CMP.

5            Relationships with other plans.

6            Configuration audit.

4                                 Configuration change management responsibilities

Configuration change management is to be applied by the IPT to:

1            Maintain effective control of the approved configuration.

2            Ensure that change proposals are processed in a timely manner and are justified in terms of:

2.1          Performance.

2.2          Whole-life costs.

2.3          Support.

2.4          Project timescale.

3            Apply a classification, including:

3.1          Applicability of change.

3.2          Possible need for retrospective action.

3.3          Degree of urgency.

4            Evaluate the impact of major deviations/production permits, waivers/concessions and modifications.

5            Enable the implementation of authorized changes and make use of configuration status accounting to track progress from concept through to completion.

6            Ensure that the impact of individual modifications is assessed across the whole fleet/equipment range and that an annual review process maintains the agreed progress of embodiment.

7            Ensure that a proposed modification is affordable and within budget by conducting a cost analysis and by obtaining financial approval.

8            Ensure that a focal point for the maintenance of CM is appointed and a statement included in staff terms of reference identifying individual authorities and responsibilities for CM within an IPT.

9            Ensure that, where items of equipment are shared across multiple IPTs, CM is strictly maintained and duplicated activities are avoided.

10        Review configurable item user data periodically on the Supply Central Computer System, or from other suitable sources, to ensure duplication of CM activity is avoided.

11        4Ensure that all relevant CM system supporting information is included during transition in accordance with the IPT/Project Programme Management document, see paragraph 6, item 6.3  The CM system is to include the plan and supporting information, eg configuration baseline, control system, data, decision histories and audit trail records.

5                                 Maintenance of Configuration Control (CC)

5.1                           Configuration Status Record (CSR)

Initial Configuration Control (CC) is vested in the Designer, who provides the Configuration Status Record (CSR).  This contains the indexes to master sets of drawings, amendments, modifications, ancillary equipment and Service-supply items.  It is kept up-to-date throughout the life of the equipment, on behalf of the IPT, by either the Designer or an agent.  The CSR provides a baseline for defining the as-fitted and modification state throughout the life of an equipment.  Normally a CSR is produced for each item of equipment for which a Certificate of Design is required.  Certification of the Design occurs when the IPT Project Engineer and the Designer agree that the design meets the specification, subject to any exceptions or limitations.

5.2                           Design changes

Changes to design records are to be carried out in accordance with Def Stan 05-123 or as contracted.  All modification procedures are to conform to the guidelines and procedures described in this JAP, single-Service APs and any subordinate Business Procedures.

5.2.1                        Publications

5.2.1.1                  Designer modifications

Once a modification has been classified and appears in the CSR, information relating to its maintenance and repair is to be included in the Topic 1 and Topic 6.  The 4Publication Organization3 is to ensure that the 4Design Organization3 amends the Topic 3.

5.2.1.2                  Service Modifications (SM)

For SM, the IPT is to ensure that a Service Amendment Leaflet (SAL), format at Chapter 8.2.2, is included in the affected Topics.  The Topic 3 will only be amended if there is a cover modification.  The IPT is to ensure that SM leaflets are published in the appropriate Topic 2 or AP 100N-03 series.

Note:

The SAL replaced the single-Service ABTAL, RNTAL and RAFTAL.

5.2.1.3                  All modifications

The IPT is to ensure that Topic 5 maintenance schedules are amended.  If the modification affects aircraft or equipment handling, refer to Chapter 10.1 paragraph 4.1.
