It is best to have a software, or at least a tracking system. Inventory is a must as well as policies, procedures and a process that keep control of assets location, owner/user, transfer of assets, relocation, return and most important purchasing and disposal of assets. Investment study must be part of purchasing of assets, financial analysis on fixed asset financial performance keeps you on top of your investment return. Many more techinques are used to ensure your investment return is optimized. Hope this is helpful?
