Equipment service management and rental (ESM&R) refers to equipment services management throughout the heavy equipment life cycle. Increased competition and slim margins in heavy equipment sales and rental place a heavy burden on manufacturers, dealers, rental companies and service businesses to improve their service performance. Improving service in these conditions is critical to maintaining margins and growing profitability. The ESM&R approach provides an integrated view of the heavy equipment business. Thus manufacturers, dealers, suppliers, rental and services business can improve the value their customers derive from their equipment and subsequently improve their own profitability and reduce cost at the same time. Collaboration is a critical factor in the equipment supply chain.

Thus heavy equipment, just like any product life-cycle has its own life-cycle. The main stages of the heavy equipment life-cycle are:
