Gantt and PERT - OCR AL Business (new spec)

This is one of a set of Powerpoints (and accompanying Notes/Key Terms sheets) that I have created for my own teaching of various sections of the new (linear) OCR A-level Business specification (H031/H431). They follow the order of teaching recommended by the exam board and (generally) the OCR-approved textbook (Mottershead/Grant/Kelt, 2015).
