From business performance to business processes

A value chain is a set of operations performed in a chain industry to create value .
In this way, in each loop, value is added to the final product .

The value chain model helps us to have a more accurate analysis of organizations and companies that have the ability to create value and competitive advantage. The main activities of a value chain include the following:
1. Internal procurement :
includes receipt, storage, warehousing , control, transportation, and planning.
2- Operations :
including machining, packaging, assembly, maintenance and repair of equipment, product testing, and all work that converts inputs into outputs.
3- External procurement :
includes all activities that are done in order to deliver the finished product to the customer , such as: distribution management, transportation, order completion , and warehousing .
4- Marketing and sales :
Activities that make the buyer buy the product. Such as: distribution channel selection, advertising, promotion, pricing, and retail management .
5- Services :
Services that increase the value of the product for the customer. Such as: support services , telephone answering, etc ....

"The value chain provides a high-level sequence of operations that the organization performs."

In order to provide a more detailed view, this high-level business operation is broken down into smaller operations and, ultimately, into operational business process activities . To do this, analyzing the yield Functional decomposition a selection of techniques.

For example, in the figure, the activities of simple checking , order analysis, and advanced checking by executive constraints are related. In this example business process by analyzing orders starts and then a decision on the process used, check the simple or advanced search Done. This process is assigned to a start event and an end event. That is, the business process begins and ends with these events.

When a business process begins, the business operations that are involved need to be implemented. Therefore, every activity in a business process needs an evolution. Therefore, the completion of a process can be based on the performance of the information system. Such as: registering a new customer or booking a flight. An activity can also be completed by a knowledge worker without the use of information systems.
