The syllabus covers relatively few theories or models. Those selected are well known and relatively straightforward to understand. The idea is that candidates should understand how theories or models help people think about issues. The inclusion of a theory or model does not necessarily mean that this is regarded as the only relevant theory in the area, but is one that is most well recognised in the management literature. BT/FBT will not examine specific theories or models which are not explicitly named somewhere in the syllabus, so it is worth gaining a good knowledge and understanding of those which are.
