L15 - Configuration Control Management Flashcards
What is Configuration Management?
Discipline that focuses on establishing and maintaining consistency of a system’s or product’s:
• Performance,
• Required functional/physical attributes,
• Design solutions and
• Operations throughout its life.
What are the major objectives of Configuration Management?
(1) to identify and document the functional and physical characteristics of a product, to control changes to those characteristics, to record and report change processing and implementation status and to verify compliance with business agreement and other applicable documents
(2) To enable all the actors in the project, at any given time
during the life-cycle, to use identical data, in the same
controlled status
What are the detailed Configuration Management objective?
(1) know at any moment the technical description of a system and its components, using approved documentation,
(2) control the evolution in the system’s technical description,
(3) provide traceability of the evolution of the system’s technical description,
(4) facilitate the consistency of the system’s components (control of external interfaces) and the products that make up these components (control of internal interfaces),
(5) verify that documentation is and remains the exact image of the products it describes,
(6) identify the current configuration baseline and the as-built configuration, in order to deal with discrepancies detected during production, delivery or operation of the product,
(7) enable any user to know the operational possibilities and limitations of each product item and, incase of nonconformance, to know which items are affected. [ECSS-M-40A]
What are the mandatory responsibilities of Managers when applying Configuration Management?
Preparation of Contract Documentation Requirement List (CDRL)
Preparation of Documentation Requirement Description (DRD)
Documentation Status Control (preparation, review, approval, distribution, change)
Give examples of Contractual Documentation/Date Requirements List.
System Specification Subsystem Specification Project Plan Design Plan Master Time Schedule Manpower and Cost Plan Monthly Status Report
What is included in the Configuration Baseline?
Specifications • System • Subsystems • Interface Control Documentation (ICD) • Functional Tests • Environmental Tests Engineering Drawings Standardizations • ECSS • MIL Std. • NASA Manuals • Installation • Maintenance Procedures • Test • Operations
The Configuration Control Function identifies, controls and reports what?
- Baseline control including identification and documentation of functional & physical System/Subsystem/Equipment characteristics;
- Control of changes to the characteristics of the identified items, with verification of compliance to agreed requirements;
- Detection of implication of changes applied to one configuration items on others and on systems;
- Recording of changes, documentation and reporting of changes and implementation status;
- To make sure that all project participants have the same view and use identical data during the life cycle of the project, in a consistent and controlled manner.
What are the Configuration Management Steps?
- Configuration Baseline Control
- Configuration Item Data List (CIDL);
- As Designed Configuration Data List (ADCL)
- As-Built Configuration Data List (ABCL)
- None Conformance Report (NCR);
- Request for Deviation (RFD);
- Request for Waver (RFW);
- Engineering Change Proposal (ECP);
- Contract Change Notice (CCN).
What is the process of identifying the technical documentation defining the approved configuration of the system or item? (Configuration Management)
- Apply technical and administrative direction
- Requirement identification of hardware and software items
- Identify physical characteristics
- Control changes
- Record and report changes and the implementation status
- Verify that the configuration meets the functional and physical requirements
Who assures formal implementation and review of changes in Configuration Management?
The Configuration Control Board (CCB).
When should Configuration Control (CC) be implemented?
At System Requirements Review (SRR) to be confirmed at Preliminary Design Review (PDR).
What are the Specifications Document of Configuration Control?
- System / Subsystem design specifications
- Test specifications
- Interface specifications (interface control document – ICD)
- Drawings
What are the two Change Classifications?
• Class I: major change effecting contract with impact on
performance, schedule and costs
• Class II: minor change at a lower level in-house changes
What document provides engineering information to support formal change approval and contractual authorization?
The Engineering Change Proposal (ECP)
What is the Configuration Control Procedure?
(1) Baseline control including identification and documentation of functional and physical characteristics of systems, subsystems and products;
(2) Control of changes to the characteristics of the identified items, with verification of compliance to agreed requirements;
(3) Detection of implication of changes applied to one configuration items on others and on systems;
(4) Recording of changes, documentation and reporting of changes and implementation status;
(5) To make sure that all program/project participants have the same view and use identical data during the life cycle of the program, in a consistent and controlled manner.
