GRAID™ Investigation Tool

Developed by InterDynamics and Integrated Safety Support, the GRAID Investigation Tool can be used to rate the likelihood of fatigue contributing to an accident or incident. This systematic and situation specific assessment tool offers organisations a consistent and practical approach to reviewing incidents, accidents, occurrences or fatigue reports as part of their Fatigue Risk Management System (FRMS). A key outcome of the Tool is a GRAID Scorecard, and an indication from Low to Very High of the likelihood that fatigue was a significant contributor to the occurrence.

InterDynamics has developed the GRAID Investigation Tool to support organisations in the ongoing improvement of their FRMS. In an occurrence investigation, GRAID facilitates a systematic approach, and the ability to identify the relative contribution of fatigue-related elements. Organisations can use the GRAID Scorecard results to target high priority areas for improvement or further detailed review.

GRAID IT applies a risk grading system developed by Zurich Risk Engineering. Information from the grading process can be used to enhance the development and implementation of the organisation’s fatigue risk management initiatives.

GRAID IT provides users the opportunity to review 20 fatigue-related elements to test the likelihood of fatigue as a contributing factor. The elements are grouped into 3 review stages:

  1. Stage 1: Details
  2. Stage 2: Preliminary
  3. Stage 3: Extended

Stage 1: Details, prompts the user to document any facts, data, and/or comments associated with the occurrence or fatigue report being investigated, under the ‘Information Details’ field of each element. A user can choose 3 options when completing a Stage 1 element:

  1. SUBMIT – when submitting documented ‘Information Details’.
  2. Don’t know? – no information is available to document.
  3. NA – when the element is not applicable to the investigation

Stage 2: Preliminary, takes the user through eight initial questions pertaining to the specific individual(s) involved and circumstances surrounding the occurrence. The grading of these questions determines whether there is a strong indication that there was a Low likelihood that fatigue was a significant contributing factor in the occurrence. If so, the grading may be concluded at that point. If however the likelihood was not determined to be Low, any of the preliminary questions were answered ‘N/A’, ‘Don’t Know’, or not answered, then the user is required to continue through the complete grading to receive a GRAID outcome and likelihood rating

Stage 3: Extended provides a higher resolution of investigation, with consideration to both personal and corporate/systemic fatigue-related contributors.

Users have 5 options under each of Stage 2 and 3 elements, incorporating the grading scale.  Once selected, grading scales for each element are summarised in the GRAID Scorecard and can be reviewed at any time.

There are no mandatory elements within GRAID, although users will need to complete a sufficient number of Stage 2 and 3 elements to receive feedback on the likelihood of fatigue being a contributing factor.
