AI.15 Further Investigation Justified Context

If a significant contributing/root cause has been confirmed we will likely have created more data about the impact of the issue during the investigation and validation process. In this case we should use the new data to re-evaluate the impact of the issue (previously done in AI.09 Determine Issue Ranking). If the issue continues to rank high enough then we should proceed to the development of appropriate control actions. However, if the issue ranking is significantly reduced the issue may be put aside or closed in order to deal with higher ranked issues. Purpose To decide, after investigation, whether resources should continue to be allocated to the issue. Quantity One decision whether to continue to allocate resources to a process issue. Quality The ranking identified from the validation data shall be compared to the expected ranking specified during TA AI.10. If the issue ranking calculated on the validation data is high enough to justify the continued resourcing of the Analyse and Improve process, the issue can be approved to proceed to the development of control actions. The decision to proceed with or to stop the investigation should be recorded with the Investigation Work Order. Resources This task is completed by the manager responsible for the process. Time As soon as practical after validation data has been analysed.
