====== Maintenance Outcome ======

[[public:99_annexes:annex-b-terms-and-definitions:start|Go to Terms and Definitions]]

===== Discussion =====

A Maintenance Outcome records the result produced when a maintenance activity is completed or terminated. It states what happened without assuming that the intended change succeeded or that the Maintained Item satisfied its applicable Requirements.

A Maintenance Outcome may indicate that the maintenance activity:

  * Completed successfully
  * Completed with identified deviations
  * Failed
  * Was suspended
  * Was canceled
  * Was rolled back
  * Produced no change

The Maintenance Outcome may reference the [[public:99_annexes:annex-b-terms-and-definitions:m:maintained_item|Maintained Item]], authorized change, implemented change, verification results, regression-test results, applicable [[public:99_annexes:annex-b-terms-and-definitions:b:baseline|Baseline]], and responsible [[public:99_annexes:annex-b-terms-and-definitions:a:authority|Authority]].

===== Definition =====

//result produced by the completion or termination of a maintenance activity//

===== Source =====

===== Note =====

A Maintenance Outcome is not necessarily a successful result. Recording unsuccessful, suspended, canceled, rolled-back, and no-change outcomes prevents an attempted maintenance activity from disappearing from the record.

A Maintenance Outcome differs from a [[public:99_annexes:annex-b-terms-and-definitions:v:validation_decision|Validation Decision]]. A Maintenance Outcome records what resulted from the maintenance activity. A Validation Decision determines whether applicable Validation Criteria are satisfied.

The outcome may be used as [[public:99_annexes:annex-b-terms-and-definitions:e:evidence|Evidence]] and should retain [[public:99_annexes:annex-b-terms-and-definitions:p:provenance|Provenance]] and [[public:99_annexes:annex-b-terms-and-definitions:t:traceability|Traceability]].

===== Example =====

A maintenance activity replaces a [[public:99_annexes:annex-b-terms-and-definitions:t:test_executable|Test Executable]], but regression testing identifies an unintended change in previously verified behavior. The recorded Maintenance Outcome indicates that the change was rolled back and references the regression-test results that caused the rollback.
