This document discusses service business development in manufacturing companies. It notes that while traditional service research has peaked, service business in manufacturing firms is an emerging topic. As manufacturers move downstream towards services in response to globalization and new technologies, they relate to theoretical perspectives on servitization and becoming solution providers. The value contribution of manufacturers can increase through investments in services like maintenance contracts, consulting, and integration services. Research on service business development examines models for moving to services, capabilities for managing services, and types of service offerings. Case studies of companies like IBM that transitioned from products to services have driven the research field. Future work could employ stronger theoretical frameworks and study under-researched markets and perspectives to further advance the topic.
