Documentation Metrics


All metrics used in the quality model are described thereafter, with useful information and references. They are classified according to their source. Please note also that several other metrics may be retrieved but not used in the quality model.



  • JIRA authors ( JIRA_AUTHORS )

    Provided by: JiraIts

    Used by:

    Scale: 1 < 2 ≤ 2 < 4 ≤ 3 < 9.75 ≤ 4 < 80 ≤ 5

    Number of different authors who created issues during the lifetime of the project.

    A high number of authors shows diversity and improves the bus factor of the project.

  • JIRA authors last month ( JIRA_AUTHORS_1M )

    Provided by: JiraIts

    Used by:

    Scale: 1 < 2 ≤ 2 < 4 ≤ 3 < 9.75 ≤ 4 < 80 ≤ 5

    Number of authors who created issues during last month. If today is 2017-02-01 then the range is from 2017-01-01 to 2017-02-01.

  • JIRA authors last week ( JIRA_AUTHORS_1W )

    Provided by: JiraIts

    Used by:

    Scale: 1 < 2 ≤ 2 < 4 ≤ 3 < 9.75 ≤ 4 < 80 ≤ 5

    Number of authors who created issues during last week. If today is Wed. 2017-02-01 then the range is from Wed. 2017-01-25 to Wed. 2017-02-01.

  • JIRA authors last year ( JIRA_AUTHORS_1Y )

    Provided by: JiraIts

    Used by:

    Scale: 1 < 2 ≤ 2 < 4 ≤ 3 < 9.75 ≤ 4 < 80 ≤ 5

    Number of authors who created issues during last year. If today is 2017-02-01 then the range is from 2016-02-01 to 2017-02-01.

  • JIRA issues created last month ( JIRA_CREATED_1M )

    Provided by: JiraIts

    Used by:

    Scale: 1 < 2 ≤ 2 < 4 ≤ 3 < 9.75 ≤ 4 < 80 ≤ 5

    Number of issues created during last month. If today is 2017-02-01 then the range is from 2017-01-01 to 2017-02-01.

  • JIRA issues created last week ( JIRA_CREATED_1W )

    Provided by: JiraIts

    Used by:

    Scale: 1 < 2 ≤ 2 < 4 ≤ 3 < 9.75 ≤ 4 < 80 ≤ 5

    Number of issues created during last week. If today is Wed. 2017-02-01 then the range is from Wed. 2017-01-25 to Wed. 2017-02-01.

  • JIRA issues created last year ( JIRA_CREATED_1Y )

    Provided by: JiraIts

    Used by:

    Scale: 1 < 2 ≤ 2 < 4 ≤ 3 < 9.75 ≤ 4 < 80 ≤ 5

    Number of issues created during last year. If today is 2017-02-01 then the range is from 2016-02-01 to 2017-02-01.

  • JIRA late issues ( JIRA_LATE )

    Provided by: JiraIts

    Used by:

    Scale: 1 < 2 ≤ 2 < 4 ≤ 3 < 9.75 ≤ 4 < 80 ≤ 5

    Number of issues with a past due date.

    It is considered good practice to keep this number low. Either fix it or maintain its due date.

  • JIRA open issues ( JIRA_OPEN )

    Provided by: JiraIts

    Used by:

    Scale: 1 < 1 ≤ 2 < 2 ≤ 3 < 3 ≤ 4 < 4 ≤ 5

    Number of issues with a state 'open' at the time of analysis.

  • JIRA open issues (%) ( JIRA_OPEN_PERCENT )

    Provided by: JiraIts

    Used by:

    Scale: 1 < 1 ≤ 2 < 2 ≤ 3 < 3 ≤ 4 < 4 ≤ 5

    Percentage of open issues compared to the overall number of issues registered in the system.

  • JIRA pending issues ( JIRA_OPEN_UNASSIGNED )

    Provided by: JiraIts

    Used by:

    Scale: 1 < 1 ≤ 2 < 2 ≤ 3 < 3 ≤ 4 < 4 ≤ 5

    Number of issues in state open with no assignee (i.e. pending).

    It is considered to be good practice to keep this number low. In an active project, people would either work on the bug (i.e. assign it) or triage it (pass it to some other state or assigning it).

  • JIRA issues updated last month ( JIRA_UPDATED_1M )

    Provided by: JiraIts

    Used by:

    Scale: 1 < 2 ≤ 2 < 4 ≤ 3 < 9.75 ≤ 4 < 80 ≤ 5

    Number of issues updated during last month. If today is 2017-02-01 then the range is from 2017-01-01 to 2017-02-01.

  • JIRA issues updated last week ( JIRA_UPDATED_1W )

    Provided by: JiraIts

    Used by:

    Scale: 1 < 2 ≤ 2 < 4 ≤ 3 < 9.75 ≤ 4 < 80 ≤ 5

    Number of issues updated during last week. If today is Wed. 2017-02-01 then the range is from Wed. 2017-01-25 to Wed. 2017-02-01.

  • JIRA issues updated last year ( JIRA_UPDATED_1Y )

  • JIRA total issues ( JIRA_VOL )

    Provided by: JiraIts

    Used by:

    Scale: 1 < 1 ≤ 2 < 2 ≤ 3 < 3 ≤ 4 < 4 ≤ 5

    Number of issues registered in the database, whatever their state is.
