Purchasing and Supply Management Introduction

May 30, 2007 0 comments

This category is devoted to my work at Marvin Engineering within 9 months contract. I wrote this material as I researched the scope and nature of supply chain management. If you are trying to pursue a career in this industry or just an IT person who happens to have a project, I hope this material will help you to get an understanding of the principles of purchasing and supply management and their application within various types of organizations and operating environments, to examine the relationship between purchasing and supply and other functions, and to consider relevant procedures, methods and techniques.

I will touch basics on the following topics:

  • the management issues involved in purchasing and supply functions in an organization;
  • the use of IT in P & S, the hierarchical structures necessary in organizations for the efficient management of P & S and logistics;
  • the source of a purchasing officer’s authority, the selection, quality and negotiation; and legal aspects of dealing with suppliers and the use of accurate recording systems;
  • the use of different types of contract;
  • the factors involved in controlling stock and logistics in a modern organization;
  • the ethics expected of modern professional business people.

There are several sub-categories to be discussed:
