Do a Baseline Inventory First and a Verification Inventory Second. Once you have asset data in your asset tracking software, a great thing to do is to go through with a handheld and do nothing more than put all the assets in the correct locations. Just indicate the location and scan all the barcodes in that location. At the end of this effort, you will know which assets are missing. Those asset will take a while to track down. Then the next pass at your asset tracking should be to validate information about the asset when you scan it, such as serial number, assigned user, model, condition, etc. A periodic inventory and a solid set of asset movement procedures will help keep the database current.
