Selected Audit Details

The Selected Audit Details section will display any user inputs an audit requires.

Perform Audit

Pressing the Perform Audit button will run the selected audits on the selected phases, and generate a report containing the input details and results of each audit. However, before this happens, validation is run to ensure the report can be generated.

After performing the audit, the audit selection control will display the pass / fail state of the audit. If the audit passes in all selected phases, then the audit will be marked as passing. If the audit fails in a single phase then it will be marked as failing. If a selected audit has not been run, or data has changed since the previous audit, then it will be marked as needing to be rerun.

Audit Validation

Before the audit report is generated, validation is run on the selected audits and phases, to ensure that the audit report can be generated. This validation will include logical validation of the audits (e.g. is the maximum value larger than the minimum value?), and simple validation of the site (e.g. are there any connections to audit?).

Analysis

Some audits will require analysis results to be considered valid. When this is the case, a warning will be displayed in the validation form.

This warning appears once, and offers the following solutions:

  • Run Analysis Immediately. When Apply or OK is clicked with this solution selected, the site will be analysed immediately. Any phases selected for auditing that are currently not included in analysis will be set to be included.
  • Run analysis if all audits which do not require it are passed. When OK is clicked with this solution selected, if no other validation errors exist, the audits that do not require analysis are run. If all of these audits pass, the analysis will be run, the audits that require analysis will be run, and a full report is generated. If any audits that do not require analysis fail, then a report containing only audits that do not require analysis is generated. Any phases selected for auditing that are currently not included in analysis will be set to be included.
  • Only perform audits which do not require analysis results. When OK is clicked with this solution selected, if no other validation errors exist, a report containing only audits that do not require analysis is generated.

If no solution is selected when OK is clicked, if no other validation errors exist, the audits that do not require results are run. Whether all of these pass, or some fail, is reported with the option to run analysis and generate a full report, or to not run analysis and generate a report containing only audits that do not require analysis. Any phases selected for auditing that are currently not included in analysis will be set to be included.

Review Failures

After performing the audit, the Review Failures  button can be selected to quickly isolate the causes of the failing audit. In most cases, selecting an error here will take you to the appropriate location to resolve the error. In some cases solutions which can be instantly applied are provided.
