Setting up a procurement function

Does anyone have any advice on setting up a procurement function? Where to start Useful tips Useful tools Lessons learnt etc etc etc Bit of background, I am setting up a procurement team within a department in an organisation, in hope to eventually role it across the whole business. I have worked in procurement for around 8 years and have been involved with setting up a previous centre but as you would expect, the situation differs majorly. Some of the areas I have previous experience in are; eProcurement specialist Business analyst Buyer Contract & Vendor Management Sourcing Specialist Any thoughts or tips would be appreciated. Thanks, Ebony
