Enterprise resource planning (ERP) is the integrated management of main business processes, often in real-time and mediated by software and technology.

ERP is usually referred to as a category of business management software—typically a suite of integrated applications—that an organization can use to collect, store, manage and interpret data from many business activities.

In ETO, after an order is received, a part of or the whole design starts to be developed. Construction by general contractors and plant construction by engineering companies are categorized as ETO.

Engineer to order is a production approach characterized by:

1. Engineering activities need to be added to product lead time.
2. Upon receipt of a customer order, the order engineering requirements and specifications are not known in detail. There is a substantial amount of design and engineering analysis required.

The difference between the ETO approach to production and make to order products is that engineering original products to order includes the entire design process. In MTO companies typically have a fixed design and specifications to start with. The existing design is followed, even if the customer requests some customization of dimensions or materials. In engineering to meet unique customer orders, designs spring from collaboration with the customer, beginning with a need and a concept.
