 +
 +===== Discussion =====
 +
 +A Maintenance Activity is a coordinated set of actions performed to analyze, control, implement, verify, or record a [[public:99_annexes:annex-b-terms-and-definitions:c:change|Change]] to a [[public:99_annexes:annex-b-terms-and-definitions:m:maintained_item|Maintained Item]]. It provides the organizing context that relates the Maintained Item, Change, governance decisions, implementation information, verification information, and resulting [[public:99_annexes:annex-b-terms-and-definitions:m:maintenance_outcome|Maintenance Outcome]].
 +
 +A Maintenance Activity may include actions that:
 +
 +  * Identify the Maintained Item
 +  * Identify applicable Maintainability Criteria
 +  * Identify dependencies
 +  * Identify expected Change effects
 +  * Associate the Change with governing Baselines
 +  * Obtain and enforce a [[public:99_annexes:annex-b-terms-and-definitions:c:change_authorization|Change Authorization]]
 +  * Implement permitted alterations
 +  * Record alterations actually made
 +  * Verify the implemented Change
 +  * Perform [[public:99_annexes:annex-b-terms-and-definitions:r:regression_test|Regression Tests]]
 +  * Record the Maintenance Outcome
 +
 +A Maintenance Activity does not require every listed action. The applicable Change, Requirements, Policies, Constraints, Maintainability Criteria, and Change Authorization determine which actions apply.

 +===== Definition =====
 +
 +//coordinated set of actions performed to analyze, control, implement, verify, or record a change to a maintained item//
 +
 +===== Source =====
 +
 +Dido Solutions, Inc. and Jackrabbit Consulting, Inc., derived from the software-maintenance activity and process concepts in ISO/IEC/IEEE 14764:2022
 +
 +===== Note =====
 +
 +A Maintenance Activity may complete successfully, fail, stop before completion, be suspended, be canceled, or be rolled back. Each completion or termination produces a Maintenance Outcome.
 +
 +The applicable [[public:99_annexes:annex-b-terms-and-definitions:a:authority|Authority]] issues the Change Authorization. The Maintenance Activity may request, receive, record, validate, and enforce that authorization but does not invent it.
 +
 +A Maintenance Activity may contain subordinate activities or actions and may involve multiple actors, [[public:99_annexes:annex-b-terms-and-definitions:n:node|Nodes]], [[public:99_annexes:annex-b-terms-and-definitions:t:test_asset|Test Assets]], operational resources, or execution environments.
 +
 +The Maintenance Activity should retain sufficient [[public:99_annexes:annex-b-terms-and-definitions:p:provenance|Provenance]] and [[public:99_annexes:annex-b-terms-and-definitions:t:traceability|Traceability]] to relate its Maintenance Outcome to the governed and realized maintenance history.
 +
 +===== Example =====
 +
 +A Maintenance Activity identifies a [[public:99_annexes:annex-b-terms-and-definitions:t:test_executable|Test Executable]] as the Maintained Item, analyzes a proposed dependency Change, associates the Change with its governing Baseline, enforces the Change Authorization, records the implemented alteration, performs verification and Regression Tests, and records the resulting Maintenance Outcome.
