If you take a look at a larger organization, one of the real benefits of an SMS system is data. The more data you acquire on your operation, the more data you can mine on incidents—incidents that are captured before they become accidents so that you can proactively deal with them. These are invaluable.
In terms of the larger organizations, virtually all of them end up with sophisticated computer tracking programs and analysis systems to handle all of this data. If that's the expected norm, the cost of the actual programs and the administrative burden to run them can both be very high. However, if that data collection in a small operation can simply be handled by a written log, and that's the expectation of the inspector, then life is good. It satisfies the purpose and gives the small operation that ability to focus on these items without a huge burden. But if the expectation is that you'll have a sophisticated data system, computerized, and somebody to look after it and run monthly reports, it's a problem.
