Larry 2T5EC846363J958473 1020 03/15/2008 NOTE: These assignment records are currently kept in a spreadsheet. Management would like a solution to two current issues with this method: 1) They are unable to quickly tell where a vehicle is when there is only one of a particular make/model/color in stock, and an employee has that vehicle checked out to them; and 2) The history in the spreadsheet makes it difficult for them to find only current assignments. Also note that some of the VINs are made up so they may not match the standard pattern.
