An alcohol check pilot is the stage where you apply, at an actual site, the procedure for checking whether members are under the influence of alcohol at set times, such as before arriving for work, before crew duty, or before a task. In safety-sensitive work such as heavy equipment operation at manufacturing and construction sites, or driving and crew duty in transport and aviation, what matters more than the test itself is that no one who should be checked is missed, and that the necessary actions after the check follow through on site.
Whether to go live is hard to judge from the number of positive results or completed tests alone. A pilot needs to verify together whether the scheduled people actually took the check, whether the flow held up even at busy times, and who handled situations such as re-checks, disputes, and work holds, and how. So it is practical to build the go-live metrics on four axes: coverage, on-site flow, follow-up actions, and unverified items.
Look at coverage against scheduled headcount rather than completion rate
A result showing that every participant completed the check does not show readiness for full operation if only people who signed up were included. You need to look, over the same period, at the scheduled headcount for each shift, the actual number of participants, the number whose final check was completed, and the number not completed with reasons. Cases excluded in advance, such as leave or off-site work, must also be separated from cases where people left because the line was long or were missed because no staff member could be found, since the points to improve differ.
It is best to use the actual number of people scheduled for the check as the denominator of the completion rate. A pilot in which only 20 volunteers took part and all finished, and a pilot in which most of the scheduled headcount was checked within the set time, cannot be expressed by the same figure of 100%. If a particular shift or night workers were missed, do not treat it as lowering overall performance. Record it as meaning that the arrival pattern and staff assignment for that shift have not yet been verified.
Record the route at peak times separately from staffing conditions
The time when problems are most likely in full operation is when arriving workers crowd in all at once. Look at the number of people waiting, cases where waiting delayed the start of work, and the time slots in which people needing a re-check remained. However, if you put in more supervisory staff than usual during the pilot, a smooth flow may be the result of the extra staffing support rather than an achievement of the equipment or procedure alone.
As a hypothetical example, suppose the line was short at the morning shift check, but three supervisors split guidance and recording between them. The observation is "there was no wait," but the interpretation should be "it has not been confirmed whether three people will also be needed at go-live." A possible action is to run it again with the staff normally available, or to try changing where guidance is given and in what order. Verification of that condition is complete when the scheduled headcount is checked and the necessary follow-up is finished within the set flow without extra support.
| Decision item | Facts to look at in the pilot | How to use it in the go-live decision |
|---|---|---|
| Coverage | Scheduled headcount by shift, number of participants, reasons for non-completion | Check whether the missed shifts and reasons have been resolved |
| On-site flow | Waiting at peak times, waiting for re-checks, support staff | Check whether the flow works under regular staffing conditions |
| Linking actions | How contact and alternative work assignment went in work hold cases | Check whether a responsible person was designated and the action was completed |
| Exception verification | Whether disputes, absent staff, or missing records occurred | Separate what was actually confirmed from unconfirmed items |
Confirm that held work is followed through to the end
When it is decided, based on the check result, not to proceed with work right away, the procedure does not end with recording the test result. You need to confirm how the actual actions connected, such as who told the member about the next procedure, who took over the on-site work, and whether the supervisor or designated responsible person was reached. There is no need to share individual results widely, but the operations lead must be able to confirm whether the action was completed.
If there was never a dispute or re-check, you cannot conclude the procedure worked well. Such situations may simply not have occurred, so they were never tested. Without producing actual individual results, you can check the route from intake to handoff to the responsible person to closing the record through role-played scenario practice or test data. The completion standard is not "a procedure document exists" but a state in which it has been confirmed on site who takes over even when staff are absent or a re-check is requested.
Handle individual results and operational metrics separately
When you bring pilot results to the go-live meeting, organize them around operational totals rather than distributing individual test results like performance data. Coverage by shift, times when waits occurred, reasons for non-completion, and whether re-checks were handled are the information needed to improve the program. Results that can identify individuals and details of individual actions, on the other hand, are better managed only to the extent needed to handle each case, which also fits the purpose of the meeting.
Missing records are not just an administrative issue. They are an operational defect that makes it impossible to confirm later whether a check took place and whether follow-up action was taken. If records keep going missing, even when tests were carried out properly, you can choose to postpone going live and fix the recording flow first. If you have not decided who will check what, and when, after go-live, it is also hard to use the figures obtained in the pilot as a baseline for comparison.
Set criteria in advance for expansion, conditional extension, or stopping
At the pilot's closing meeting, decide not whether all the metrics look good, but whether you have answered the operating assumptions you set out to test. If every shift was checked within the scheduled scope, the route held up under regular staffing, and the handling routes for holds, re-checks, and missing records were verified, you have grounds to consider expanding to full operation. This also aligns with the intent of risk assessment, which identifies risk factors and sets up and carries out improvement measures.
Conversely, if a particular shift was missed or a staff-absence situation was not confirmed, a conditional extension may be more appropriate. In that case, rather than just lengthening the period, write down which shifts to include and which situations to test, who is in charge, and what must be confirmed to end it. If problems that block safe operation, such as missing original records or gaps in who is responsible for actions, keep recurring, you need to prioritize fixing the procedure over expanding the scope.
The go-live decision document can summarize on one page the items confirmed, items not yet confirmed, corrective actions, responsible people, and when the decision will be revisited. This approach keeps you from over-interpreting a low number of positive results and links the pilot to the metrics you will keep watching after go-live.
