Every Jamaican organisation inside the Data Protection Act's scope needs someone accountable for privacy. Very few mid-market firms need that person full time, and the ones that appoint an internal volunteer usually appoint whoever cannot say no.
The retainer model has settled into a recognisable shape locally: a named officer registered with the regulator, a fixed number of advisory hours a month, breach response on call, an annual review of the processing register, and staff training once a year.
It works because the failure mode of an internal appointment is not incompetence, it is time. A finance manager doing privacy in the gaps will keep registration current and let training, retention and processor contracts drift — and those are exactly what a complaint exposes.
Two cautions. Check the retainer names a specific individual rather than a firm generally, and check what happens outside the included hours: an incident does not respect a monthly allocation.
