Controlling costs is good business. It is good business for supply chains that deliver goods and services to customers. And it is good business for organizations like Procurement and Finance that are responsible for managing indirect spend.
Companies that are working to control costs by getting handle on indirect categories like Travel and Entertainment should be monitoring the consumerization of IT for new opportunities. For example this video from Diana Gray of Oracle shares great perspective on how smart phones can increase the efficiency and velocity of expense reporting. This frees sales people from paperwork and gives them time to focus on selling customers. And keeping sales people selling is good business too!
