System gastronomy is a form of catering with standardised processes, a uniform concept and central control across multiple locations.

Chain catering (systemised gastronomy) is a special type of operation within the hospitality sector that distinguishes itself from individual, owner-run establishments through standardised organisational structures and processes. The focus is on the efficiency and uniformity of operational procedures, with the aim of offering a consistent product range of consistent quality. Key features are defined business concepts, central control and the standardisation and multiplication of procedures.
All key processes are coordinated by a head office and implemented uniformly across the branches. The branches follow standardised procedures set out in extensive manuals covering the following areas:
The appearance and fit-out of the branches as well as the quality of the food and drink are also standardised. Many chain catering companies are part of a franchise system in which the franchisor provides proven concepts for a fee. Standardised concepts reduce the workload and enable efficient staff and stock management, while guests benefit from a consistent corporate identity.
Whether a company is classified as chain catering is based on an analysis of concepts for replication, market development and a sophisticated corporate design. Criteria assessed include the ability to be multiplied, existing standards, central purchasing and marketing control as well as uniform fit-out and customer-service standards.
