CRM implementation in 3 phases is a simple overview of the complex process of CRM-system implementation. Most CRM-systems fail because too many functions are implemented from the get go. And most often CRM-systems silt up because the project manager does not have the necessary authority to enforce the time frame and set goals. Especially for medium-sized companies it is imperative that the system matches the company’s available resources, needed functionality and processes. Unnecessary and complex functions usually means additional cost and effort that don’t have any use. When selecting a system don’t forget the people who have to manage their work day with the new software.
