My knowledge of TBIPS is relatively new. In my new role as director general of the professional services transformative solutions sector, TBIPS is one of seven methods of supply that are mandatory for other government departments to use when they want to access professional services. TBIPS specifically stands for task-based informatics professional services. It is access to professional services in the area of information technology on a task-based basis as opposed to a solution-based basis.
That's what I know about TBIPS, and I know that's the method that was used.
