Workgroup Overview

Built upon the well established principles of Enterprise Architecture, this workgroup created an Industry Architecture for hospitality, which includes business, application, and data architectures. Recognized by ComputerWorld magazine as the first such effort of its kind, this architecture is making it easier for hotels to buy and architect systems that are compatible with key design principles such as Service Oriented Architecture, which in turn aids migration of systems out of hotels and into the cloud. The result is that it is also simpler for vendors to provide software products which conform to established business practices. Ultimately, this effort provides increased choice and flexibility in hotel IT purchases and helps IT decision makers in selecting best of breed solutions.

Business Benefits include:

  • Eases the use of existing systems, and the acquisition and integration of new systems
  • Eases the assimilation of systems across a multi-property enterprise and the roll-up of data across the various definitions of enterprise
  • Enables a vendor to provide a software product based on a functional model, which conforms to established business practices
  • Enables IT consumers to make informed decisions when selecting components
  • Facilitates interoperability across components for the purposes of accelerating deployment and lowering the total cost of ownership
  • Provides increased choice and flexibility in IT acquisitions, and supports IT decision makers in selecting best of breed solutions

Workgroup Overview

Business Problem

The hotel industry is large, diverse, global, and fragmented. Our industry is hampered by a lack of common understanding of business functions, business services, roles, use cases, requirements, technology components, applications, and data concepts.

A single common Information and Technology (IT) Reference Architecture benefits the industry by:

  • Providing a common understanding of IT Architecture elements, Industry needs and solutions
  • Improving communications through common understanding
  • Providing an architecture baseline to leverage for jumpstarting architecture efforts within companies in the industry
  • Reduction of costs associated with the acquisition, integration, and deployment of IT components

The first cycle (ADM1) established a Reference Architecture for a small, independent, limited service, U.S.-based hotel. The second cycle (ADM2) enhances this architecture by adding event and banquet management business functions.


  • IT products designed with the baseline architecture taken into consideration


  • Revised Business Architecture; adding event and banquet management functions to the existing business architecture
  • Revised Application and Data architectures supporting event and banquet management
  • Revised SOA addendum, diagram package, and integration with existing documentation

Meeting Schedule

The workgroup is retired and thus, does not meet.

Most Recent Project

The workgroup has completed a second iteration of the Industry Reference Architecture through the TOGAF Architecture Development Method (ADM). This iteration includes full-service hotels with full F&B and conference facilities. Working documents on this iteration are available on the Workgroup's Collaboration Site.
