Anyone who knows me well, will know that I like to cook. One of my favourite things to cook is a pie. Yesterday, my summer pie was a lovely cheese and potato pie, made with camembert. The first cut inviting the melted gooey cheese to ooze out, like lava flowing from a volcano. So it got me thinking about procurement in the context of a humble cheese and potato pie and what lessons of best practice we can learn, particularly when preparing procurement documents.
