In innovative companies the turnover from service is often also the main profit earner. Basic requirements for this, besides strategy the service product management, are efficient customer service and promoting customer loyalty with high availability (e.g. 24/7). Service management therefore also includes planning and operating the full service spectrum. In view of that,  a profitable way to drive processes is by perfecting IT/ERP for services,  especially in businesses where demand fluctuates. This is often achieved by focussing on preventive services and monitoring. Today, the entire service chain can be automated.
