As changes occur in the way of running a business, we need to have a structure in place to support change and take advantage of new capabilities, for example, IT.  It becomes necessary to consider new skill sets, the way work is organised/allocated amongst staff to greatest effect. How do we manage the impact of change upon current employees to minimise negative outcomes?  IT necessitates a review of how things are done.  Business Process Reengineering (BPR) is a process to document and define how work will be done to realise greatest benefits.
