This Software Configuration Management (SCM) Plan (SCMP) describes the SCM organization and practices applied consistently and uniformly throughout the life cycle for Computer Software Configuration Items (CSCIs) that are developed or maintained by [originating organization].

SCM is the process used during software development and maintenance to identify, control, and report functional and physical configurations of software products (e.g., source code, executable code, databases, test scenarios and data, and documentation).


Purpose

The purpose of this document is to define SCM responsibilities (requirements), resources, and processes used during the development and maintenance of the [system title] system. Figure T1 provides an overview of the SCM functions. In the figure, Data Management (DM) is shown connected to SCM with a broken line. DM is a sub-function of SCM with SCM having overall cognizant responsibility. Section 5 describes the DM responsibilities. Software Quality Assurance (SQA) is a separate function that works closely with SCM to ensure the integrity of the product (i.e., SCM controls the product; SQA certifies the integrity of the product).

SECTION 5 CONFIGURATION IDENTIFICATION

This section describes the process for configuration identification.

Selection of CSCIs

The selection of CSCIs is the responsibility of project management or the developer. CSCIs are placed under configuration management in accordance with this plan. Once the CSCI has been identified and provided to the SCM organization, the SCMP will be updated.

Formal Baseline Establishment

For each CSCI, configuration identification is established for software technical documentation, code, and media. The initially approved configuration identifications establish baselines from which subsequent changes are controlled. The configuration identifications and baselines to be established for [system title] CSCIs are defined as shown below.

  1. Functional Baseline. Listed below are the documents that comprise the Functional Baseline for [system title].

    • Document 1
    • Document 2
    • Document 3
  2. Allocated Baseline. Listed below are the documents that comprise the Allocated Baseline for [system title].

    • Document 1
    • Document 2
    • Document 3
  3. Product Baseline. Listed below are the documents that comprise the Product Baseline for [system title].

    • Document 1
    • Document 2
    • Document 3

Identification Methods

The paragraphs below describe the methods used in identifying the CSCI and associated technical data and project-developed support software required for development, test, and maintenance.

5.3.1 Document Identification

SCM assigns unique numbers to CSCI documents. Each page of the document contains the identification number with the applicable revision letter.

5.3.1.1 Document Revision

SCM assigns identifiers to document revisions.

5.3.1.2 Document Change Pages

SCM assigns numbers to document change pages.

5.3.2 Drawing Identification

SCM assigns unique numbers to drawings.

5.3.3 Software Identification

SCM assigns unique numbers to drawings.

5.3.3.1 Copy Number

Each accountable copy of a software product (e.g., source code tape), with the exception of the EM and listings, is assigned a unique copy number, both externally and embedded within the software.

5.3.3.2 Volume Number

For software products that require more than one unit of physical storage per copy, a volume number is assigned to each unit of storage, both externally and embedded on the software.

5.3.3.3 Labels

[system title] software is labeled for ease in identification. Describe the specific labeling practices being used.

Listed below is the minimum information necessary to adequately identify software media.

  1. Identify each of the elements required on a label.

5.3.4 Firmware Identification

The components of firmware, the hardware device, and the computer instructions or computer data that reside as read-only software on the hardware device are each uniquely identified. Firmware identification includes the top-level document/drawing that defines how these components fit together for the firmware assembly. Firmware is assigned a unique identifier.

5.3.5 Change Request Form Identification

Each change request form received by SCM is assigned a unique identifier.

5.3.6 Engineering Release

The software release process begins at the start of system integration and testing. At the initiation of this phase, the software Product Baseline is established by the project's SCCB. The software release identified as part of the Product Baseline is provided for integration with the operational hardware. Final testing is accomplished by Operational Test and Evaluation (OT&E). Issues found by OT&E are resolved using the baseline change process. Upon satisfactory completion of OT&E, the software release is approved as the Product Baseline Configuration. Approval for service use initiates distribution to Fleet users. CM/DM is responsible for making and distributing copies of software products. The copies are made from the EM. SCM is responsible for ensuring that the correct software product and release documentation are distributed through DM.

Developmental Configuration Corrective Action Process

Anomalies or discrepancies against the Developmental Configuration are resolved through a corrective action process. The corrective action process is a closed-loop process, ensuring that all detected problems are promptly reported and entered into the process, action is initiated on them, resolution is achieved, status is tracked and reported , and records of the problems are maintained for the life of the product.

The corrective action process is the development team's internal control over software that is evolving from requirements and being developed through design, code and unit test, integration test, and software system test.

The Development Group is responsible for the Developmental Configuration and therefore provides status of implementing change proposals and closing out the change request form. The paragraphs below describe the steps in processing a change request form.

  1. The initiator reports a problem using a change request form and submits it to the SCM organization.
  2. SCM assigns a change request form tracking number, updates the change request form tracking database, and provides a copy to the development team for problem analysis and proposed solution. A master copy of the change request form is maintained by the library.
  3. The approval authority determines the corrective action to be taken and the priority of the action. Corrective actions may be returned to the Development Group for implementation or sent to another group for review or action.
  4. The Development Group implements the approved solution and provides status of the implementation and completion to the SCM organization. Implementation includes updating the software and configuration documents. Implementation is considered complete when the integration and testing of the change request " passes " test criteria.

Configuration Management Libraries

The Developmental Configuration management process includes the responsibility to control documentation and repositories containing elements of the Developmental Configuration. The [project organization], in response to this requirement, has established the following libraries: Software Development Library, Documentation Library, and Drawing Library. The following paragraphs describe the functions of each of the libraries.

Project management authorizes access to each of the [project organization] libraries. Access includes types of user privileges granted (e.g., for software: read, write, execute; for documentation: loan copy, distribution copy).

5.5.1 Software Development Library

The SDL is the controlled collection of documentation, intermediate software development products, associated tools, and procedures that comprise a Developmental Configuration CSCI. The SDL provides storage of and controlled access to software development products in human-readable form, machine-readable form, or both. SDL components are initially documented in an identification list for the Allocated Baseline.

    Figure T4: Sample Product Development Evolution

The [project organization] SDL consists of a series of phases through which the software is developed. Before software is released from one development phase to the next , it must be validated by a Quality Assurance function and verified by SCM. SCM uses the [ name the tool or briefly explain the process] to perform this verification. SCM verifies that approved software changes have been incorporated into the proper phase of the SDL, reports status to the SCCB, and performs the release function upon SCCB authorization.

5.5.2 Documentation Library

The [project organization] Documentation Library contains the controlled collection of all the project's document inventory, in any media, for both released and development versions; it houses both deliverable and nondeliverable products (e.g., preliminary versions of baseline documents, specifications on commercial off-the-shelf [COTS] tools). The Documentation Library for a newly designated baseline is established at the same time as its Developmental Configuration, and its components are initially documented in an identification list for the Allocated Baseline. SCM verifies that new documents that are entered into the library as CSCIs have been approved by the SCCB and that only approved document changes have been incorporated into all controlled documents. SCM activates the release process upon SCCB authorization.

5.5.3 Drawing Library

The [project organization] Drawing Library contains the controlled collection of all of the project's drawings, Computer-Aided Design (CAD), and Computer-Aided Manufacturing (CAM) instructions. The Drawing Library for a newly designated baseline is established at the same time as its Developmental Configuration, and its components are initially documented in an identification list for the Allocated Baseline. SCM verifies that approved changes have been incorporated into drawings originated by and under control of the [project organization].


SECTION 6 INTERFACE MANAGEMENT

This section identifies the interface requirements and establishes the Interface Control Working Group . Interface management is performed to ensure compatibility and interoperability among various hardware and software components in a system as specified in the baselined configuration documentation.

SCM may be required to generate and distribute CSA reports and technical data.


SECTION 7 CONFIGURATION CONTROL

This section describes the process for maintaining configuration control of all identified CSCIs developed or maintained by [originating organization].

The purpose of configuration control is to maintain the integrity of baselined CSCIs and their associated documentation by ensuring that only authorized changes are incorporated. This requires the systematic evaluation, processing, and approval or disapproval of all proposed changes. Configuration control begins when a CSCI is baselined and continues as further baselines are established.

SCM is responsible for maintaining software configuration control over software products in the Functional, Allocated, Developmental Configuration, and Product Baselines. In addition, SCM is responsible for administering the process by which a request for change to products under control is submitted, reviewed, and approved or disapproved.

Baseline Change Process

The [project organization] baseline change process is a continuous function that involves the preparation, implementation, and distribution of CSCI and associated documentation changes. It has been approved by the [sponsor organization] and involves activity at both the project and program levels.

The assigned responsibilities and approval authority for accomplishing changes to baselines are detailed in a project-originated SCCB charter documented in [list the document name]. This charter interfaces with the [sponsor organization] charter. The charter establishes the processing of change requests and their resolution by local and [sponsor organization] boards.

Changes to a [project organization] baseline configuration are initiated through a change request process that involves the preparation of a defined series of documents (change forms) whose status is determined by a hierarchy of control boards. Change requests are used to report problems and propose changes or enhancements to software or documentation. A change request must be documented, submitted, reviewed, and approved prior to implementation. Change requests against developmental baselines are resolved by the [project organization] SCCB the SCCB, identify the board> . Change requests against established baselines require approval of the [sponsor organization] SCRB.

7.2.1 Change Request Forms

The [project organization] uses the following change forms for control of its software baselines:

  1. Engineering Change Proposals (ECPs)
  2. Specification Change Notices (SCNs)
  3. Notices of Revisions (NORs)
  4. Deviation and Waiver
  5. Local change requests ” insert title of local change request

7.2.1.1 Engineering Change Proposal

The ECP is used to document all proposed changes to established baselines. The completed ECP must include detailed descriptions, justifications, and costs for the proposed change.

7.2.1.2 Specification Change Notice

The SCN is used to correct or update specifications. The SCN identifies the document to be changed, the SCN number, its status (proposed or approved), the related ECP, and other [project organization] identifying data.

7.2.1.3 Notice of Revision

The NOR is primarily intended for use when the master drawing list and other documents comprising the configuration identification are not held by the originator of the ECP.

    SECTION 8 CONFIGURATION STATUS ACCOUNTING

    This section describes the process used to provide configuration status accounting (CSA). CSA is the recording and reporting of information needed to manage CSCIs effectively, including the items listed below.

    1. A record of the approved configuration documentation and identification numbers
    2. The status of proposed changes, deviations, and waivers to the configuration
    3. The implementation status of approved changes
    4. The configuration of all units of the CSCI in the operational inventory
    5. Results of audits

    CSA documentation is the means through which actions affecting CSCIs are recorded and reported to the Software Systems Engineering Manager of the [system title] system. It principally records the "approved configuration" (baseline) and the implementation status of changes to the baseline. It is the bookkeeping part of SCM that provides managers with feedback information to determine whether decisions of the SCCB are being implemented as directed.

    To automate CSA, SCM uses [identify the software tool], a relational database management system, to define the data content and format. [Identify the software tool] is an approved, baselined CSCI, so any proposed change to it requires a change request and SCCB approval for implementation.

    Input data includes SCCB decisions, such as approving or disapproving change requests, establishing configuration baselines, and approving the release of software for distribution. Input data also includes status information of CSCIs and change requests . Output data is formatted as CSA reports .

    8 1 Records

    The records maintained by SCM contain detailed data that documents that the as-built software conforms to its technical description and specified configuration. They include the information listed below.

    1. Approved technical documentation for each CSCI
    2. Status of proposed changes
    3. Implementation status of approved changes
    4. Status of software problems
    5. A record of change request status

    8.1.1 Change Request Table

    The change request table contains a record of all change requests and related information. It includes, but is not limited to, the data listed below.

    2. Type of release
    3. Software product released
    4. Changes incorporated into the release
    5. Approval signatures
    6. Location of masters

    8.1.5 Archive Records Table

    SCM maintains a record of all archived material. Archived material includes obsolete material and data not required for current use and off-site stored backup data in case of loss of online data.

    8 2 Reports

    SCM has the prime responsibility for managing, compiling, maintaining, and publishing the [system title] detailed software CSA reports. These reports provide the status to management that all changes between the software technical description and the software itself are being accounted for on a one-to-one relationship. This status information, together with the CSA reports maintained by the SCM organization, is an input for the final review for product acceptance.

    Project management determines the frequency of distribution and recipients of the CSA reports. These reports include the information listed below.

    1. Identification of currently approved configuration documentation and configuration identifiers associated with each CSCI
    2. Status of proposed change requests from initiation to implementation
    3. Results of configuration audits; status and disposition of discrepancies
    4. Traceability of changes from baselined documentation of each CSCI
    5. Effectivity and installation status of configuration changes to all CSCIs at all locations

    The above reports answer basic questions regarding the approved configuration (baseline) and the implementation status of changes to the baseline.

    8 3 Requests for CSA Reports

    Requests for CSA reports originating outside the project are directed for approval to Project Management, which authorizes need-to-know access.


    SECTION 9 CONFIGURATION AUDITS

    This section describes the approach used in performing configuration audits.

    Configuration audits validate that the design and the final product conform to approved functional requirements defined in specifications and drawings and that the changes to the initially approved specifications and drawings have been incorporated.

    The SCM assists in the conduct of two audits for developed baselines prior to their release: the FCA and PCA. These audits ensure that baseline changes are validated and the new baseline meets new requirements and specifications.

    SCM personnel provide assistance through the specific activities listed below, as required by the project.

    1. Assist in the audit.
    2. Review audit checklists.
    3. Prepare SCM reports , logs, or records required to support the audit.
    4. Establish and maintain baseline specification and product files.
    5. Follow up on audit reports to assess possible SCM impact.
    6. Provide storage for audit documentation, records, and products.
    7. Ensure audit report action items are resolved.

    9 1 Functional Configuration Audit (FCA)

    SCM ensures that the released version of the software products is available for the audit so that the inspectors can verify that the software performs as required by its allocated configuration.

    FCAs are usually conducted after a major change or a significant number of minor changes have occurred or before the establishment of the Product Baseline. The SCM Manager is responsible for assisting SQA in the preparation of the FCA plan. The FCA plan identifies specific tasks and procedures to accomplish those tasks . The FCA plan identifies documents, hardware, software, test sets, etc. required for performing the audit. The SCM Manager records differences between the SRS and the CSCI under audit for incorporation into the minutes of the FCA for postaudit action.

    9 2 Physical Configuration Audit (PCA)

    This audit ensures that the as-built configuration is accurately reflected by the released documentation to establish the Product Baseline. SCM audits the released engineering documentation and quality control records to make sure the as-built or as-coded configuration is reflected by this documentation.

    PCAs are usually conducted concurrently with FCAs or immediately following an FCA. The SCM Manager is responsible for assisting SQA in the preparation of the PCA plan. The PCA plan identifies specific tasks and procedures to accomplish those tasks. The PCA plan also identifies the software and technical documentation to be examined.

    9 3 Audits and Reviews of SCM

    To ensure that SCM efforts are adequate and completed as detailed in this document, audits and reviews of SCM processes and products are performed as described in the following paragraphs.

    9.3.1 SCM Audits

    To ensure that the SCM program complies with the requirements specified in this plan, an independent audit of SCM processes, procedures, and products is required. Normally, this type of audit is performed by a QA representative. Products generated or tracked by SCM are listed below.

    1. CSA reports
    2. Identified CSCIs
    3. Change requests
    4. Software version releases
    5. Libraries
    6. Documented SCM processes and procedures
    7. SCM review reports

    The audit findings are documented in an audit report and provided to the SCM Manager. The audit report is used by the SCM Manager to correct deficiencies or identify changes in the SCM requirements. Correcting deficiencies would include updating SCM processes and procedures, records, configuration documents, software, or tools. Identifying changes in the SCM requirements would result in adding, modifying, or deleting a requirement in this SCMP.

    9.3.2 SCM Reviews

    The SCM Manager periodically performs internal reviews of SCM processes, procedures, and products. An SCM review serves as a method to determine how effectively and efficiently the SCM processes and procedures fulfill the SCM requirements as defined in this plan. SCM reviews also include verification of the products generated by SCM. Verification is the process of evaluating the products to ensure correctness and consistency with respect to the SCMP, tasks, processes, and procedures. The review findings are documented in a report that is used by the SCM Manager to correct deficiencies or identify changes in SCM requirements.

    It is the SCM Manager's responsibility to perform or assign SCM personnel to perform the SCM reviews and to specify the SCM processes or procedures to be reviewed. The review report includes what actions were taken to resolve the deficiency or requirements change. The review report is filed with the appropriate DTP and serves as a record to show that an internal SCM review was performed and corrective action was taken as required. Review reports may be audited .


    SECTION 10 SUBCONTRACTOR VENDOR CONTROL

    This section describes the methods used to ensure subcontractor/vendor compliance with configuration management requirements.

    Each contractor working on this system is required to develop a configuration management plan that is in conformance to this document. The development contractor ensures that nondeliverable software will functionally meet the requirements of the system.

    Vendors' products are inspected at delivery to ensure that their products meet the requirements as specified. The vendors ' quality control procedures may be obtained to aid in the evaluation of the COTS software by the system developer.

    Configuration management personnel are acquired as a team through competitive contract negotiation. The SCM staff has responsibility for conducting the SCM function under the management of [ name of the supervising organization or function assigned by the program]. The staff is required to be fully knowledgeable in all aspects of the program's configuration management function and to maintain and upgrade the SCM program whenever they can.

    APPENDIX T3 SOFTWARE CONFIGURATION MANAGEMENT PHASING AND MILESTONES

    This section describes the sequence of events and milestones for implementation of SCM in phase with major software and development milestones and events. SCM milestones are achieved upon completion of individual SCM activities.

    T3 1 System Requirements Analysis Phase

    This is the first phase of system-level planning. During the system requirements analysis phase, the top-level (system) requirements are established, analyzed , and approved. The requirements describe the major functions that the system must fulfill.

    The outputs of this phase consist of one preliminary product (Preliminary System Specification) and a program review (System Requirements Review [SRR]). No baselines are established at this point. The SCRB and SCCB are established.

    SCM activities during this phase are listed below.

    1. Establish project SCM.
    2. Train staff.
    3. Create draft SCMP or update SCMP for existing system.
    4. Attend SRR as required.

    T3 2 System Design Phase

    This is the second phase of the system-level planning. During the system design phase, a top-level (system) design is formulated and documented. The outputs of this phase consist of four final deliverable products (System Specification, System/Segment Design Document, Software Development Plan, and Software Configuration Management Plan); two preliminary deliverable products (Preliminary Software Requirements Specification and Preliminary Interface Requirements Specification); one program review (System Design Review); and the establishment of the first of three baselines (Functional Baseline).

    The SCCB meets to establish the Functional Baseline. The SCRB meets to exercise software configuration control upon establishment of the Functional Baseline.

    SCM activities during this phase are listed below.

    1. Implement approved SCMP:

      • Identify the tasks stated in SCMP.
      • Identify processes from the tasks in the SCMP.
      • Create or update DTPs from the processes.
    2. Establish complete number scheme for project-defined version identification (ID).
    3. Exercise configuration control of the functional configuration documentation.
    4. Attend System Design Review.
    5. Establish and maintain CSA system.
    6. Establish and maintain CM library(ies).
    7. Support SCCB throughout the software life cycle.

    T3 3 Software Requirements Analysis Phase

    During the software requirements analysis phase, the software performance and interface requirements that must be met are formulated and analyzed. This phase is similar to the system requirements analysis phase except that it focuses on the software requirements derived from the system requirements.

    The outputs from this phase consist of two final deliverable products (Software Requirements Specification and Interface Requirements Specification), one program review (Software Specification Review), and the establishment of the second of three baselines (Allocated Baseline).

    SCM activities during this phase are listed below.

    1. Attend Software Specification Review (SSR).
    2. Exercise control of allocated configuration documentation.

    T3 4 Preliminary Design Phase

    During the preliminary design phase, the system-level architecture, interfaces, and design are developed. A Preliminary Design Review (PDR) is held, and approval is obtained before proceeding with the detailed (low-level) design phase.

    The outputs from this phase consist of one final deliverable product (Software Test Plan [Test Ids]), two preliminary deliverable products (Preliminary Software Design Documents and Preliminary Interface Design Document), one program review (Preliminary Design Review), and the establishment of the Developmental Configuration.

    SCM activities during this phase are listed below.

    1. Establish and maintain SDL.
    2. Establish corrective action process for Developmental Configuration.

    3. Attend PDR.
    4. Exercise configuration control of Developmental Configuration Products.

    T3 5 Detailed Design Phase

    During the detailed design phase, the design team develops the detailed design, and a Critical Design Review (CDR) is held for review and approval of the total design. The design is completed and approved at the CDR. By the time the CDR occurs, the software constituting the system has been decomposed into a hierarchical structure of CSCIs, Computer Software Components (CSCs), and CSUs.

    The preceding phases ensure that design requirements have been identified, validated , and allocated to the approved design and to their respective baselines.

    The outputs from this phase consist of three final deliverable products (detailed Software Design Documents, Software Test Descriptions [Cases[, and Interface Design Document); one program review (Critical Design Review); and the continuance of the Developmental Configuration.

    SCM activities during this phase are listed below.

    1. Attend CDR.
    2. Exercise configuration control of Developmental Configuration Products.

    T3 6 Coding and CSU Testing Phase

    During the coding and CSU testing phase, coding and unit (CSU) testing is accomplished. All design data, programmer notes, and CSU test results are kept in the Software Development Files (SDFs). This is for programmer and peer review only. SQA can perform audits of the SDFs.

    The outputs from this phase result in completed CSU development and testing evidenced by source code and source code listings. The Developmental Configuration continues.

    SCM activities during this phase are listed below.

    1. Exercise configuration control of Developmental Configuration Products.

    T3 7 CSC Integration and Testing Phase

    During the CSC integration and testing phase, coding and testing of CSCs is accomplished. CSUs are integrated into their next -higher structures and tested to ensure proper processing. Test drivers and stubs are written to perform these tests. All design data, programming notes, and test results are added to the SDFs. This is for programmer and peer review only. SQA can perform audits of the SDFs.

    The outputs from this phase consist of one final deliverable product (Software Test Description (Procedures)), one program review (Test Readiness Review [TRR]), plus updated source code, source code listings, and command files. Successful completion of these activities indicates the conclusion of the Developmental Configuration.

    SCM activities during this phase are listed below.

    1. Support TRR by providing the items listed below:

      • CSCI and associated technical data
      • Status of reported software and documentation anomalies
    2. Exercise configuration control of Developmental Configuration products.

    T3 8 CSCI Testing Phase

    During the CSCI testing phase, testing of CSCIs is accomplished to demonstrate that the software system is reliable and maintainable . All lower-level (CSU and CSC) coding and testing have been completed. This final software testing ensures that each CSCI functions as designed.

    The V&V process is a software quality check to ensure that the design is complete and that the software fulfills all approved requirements and may be performed by the Systems Test Group.

    Formal Qualification Testing (FQT) is performed in this phase. The CSCI testing is basically the FQT, whereby the customer accepts the tested integrity of the developed system. The completed Software Test Plan includes tests of user identification and access to the system, as well as test plans for any identified safety issues.

    The outputs from this phase consist of the following final deliverable products (Software Test Reports, Operation and Support Documents, Version Description Documents, Software Product Specifications, and updated source code and listings); two audits (PCA and FCA); and establishment of the last of the three baselines (Product Baseline).

    When the FCA/PCA is approved, the customer accepts the Product Baseline.

    SCM activities during this phase are listed below.

    1. Support FCA and PCA. These audits may be deferred until after system integration and testing.
    2. Release product configuration documentation.
    3. Exercise configuration control of product configuration documentation.

    T3 9 System Integration and Testing Phase

    During the system integration and testing phase, the software is integrated into the operational hardware and tested. DOD-STD-2167A development activities end with CSCI testing and the establishment of the software Product Baseline. After software Product Baseline, the software must be integrated into the operational hardware and final testing (Operational Testing and Evaluation [OT&E]) accomplished by the customer before placing the system into operation.
