In order to improve processes, it is important to define clearly the ‘As Is’ processes and how to move towards the ‘To Be’ processes. In the case of procurement, one of the best ways to describe current processes is to distinguish between the components of procurement processes. These can be described as sourcing, supply, logistics, transportation, storing, movements, and distribution. This chapter aims to present a precise definition of these terms and how they inter-relate. It also analyzes each of these processes and describes them in detail.
