Operating model is an abstract representation of how an organization operates across a range of domains in order to accomplish its function. There are different ways of classifying these domains. People, process and technology is one commonly used distinction. Process, organisation and technology is another  Andrew Campbell of Ashridge Business School refers to five domains: Process; Information systems; Locations and buildings; Organization and people; and Suppliers and business partners 
An organization is a complex system. An operating model breaks this system into components, showing how it works. It can help different participants understand the whole. It can help those making changes check that the whole will still work. It can help those transforming an operation coordinate all the different changes that need to happen.
An operating model is like the blueprint for a building. It is more dynamic than a building blueprint, with changes occurring regularly. Also, an operating model is not usually just one blueprint. There are likely to be blueprints for each domain: processes, organisation structure, decision making, software applications, locations and so on. There are also likely to be some integrating blueprints.
An operating model can describe the way an organization does business today - the "as is". A design for an operating model can communicate the vision of how an operation would like to work in the future - the "to be". Most typically, an operating model is a living set of documents that are continually changing, like an organization chart.
By contrast, a business model describes how an organization creates, delivers and captures value and sustains itself in the process; although there are plenty of disagreements about the use of the words business model and operating model.
The term operating model is used in corporate-level strategy (see History below) to describe the way in which an organisation is structured into business divisions and what activities are centralised or decentralised. It can also be used at a much more micro level to describe how the IT department operates, how a factory is laid out or how a single business works. This article does not cover the latter use.
Origins in corporate strategy
Operating model as defined here is similar to the definition from Lynch, et al., of corporate strategy: "the relationships among the businesses in the corporation's portfolio and the process by which investments will be determined among them."
Corporate strategy grew out of the research of Harvard Business School professor Bruce R. Scott who developed a model of the stages of corporate development. He traced the evolution of a firm from "Stage I" with a single product (or line of products) to "Stage 3" with multiple lines of business, markets and channels. Following this work, Leonard Wrigley and Richard Rumelt developed ways of classifying company structures and comparing their strategies. They identified four different operating models. (1) a single line of business where most revenue comes from a single activity; (2) related businesses where diversification is achieved by adding businesses that complement the original activity; (3) a diversified firm that combines unrelated businesses such as an oil company and a fertilizer business and (4) conglomerates – diversification is achieved without regard to complementary or synergistic effects.
The nomenclature evolved, but the categories survive:
- Integrated: single business, requiring a single strategy for competitive advantage. Issues are formulated centrally and tailored for local needs to optimize the business. Success is measured by adding up the global numbers. Examples include McDonalds or Harley Davidson.
- Allied-Related: each business contains the ability to create advantage autonomously. Common interests are worked across businesses. Some support work may be shared across businesses. Examples include Canon and Procter & Gamble.
- Allied-unrelated: each business contains the core work required to create advantage autonomously. Customers may be shared. Common interest are worked across businesses. Capabilities that portable to other businesses are shared for leverage. Examples include Avery Dennison's pressure-sensitive technology and self-adhesive base technologies that are used in Roll Materials medical group for single-use medical products.
- Holding company: includes unrelated businesses, with multiple strategies, related or not. Each business has self-contained brands/businesses with independent functional groups. The units are tied together only by ownership. Examples include Tyco International.
Some implications of the choice:
|Corporate Role||Resource allocations||Define Protocols||Define Protocols||Financial roll-ups and analysis|
|Human Capital||Common||Some Shared||Some Shared||Independent|
|IT Systems||Common||Common||Few, interconnected||Different|
|Enabling Processes||Centralized||Centralized||Some Centralized||Decentralized|
The MIT Center for Information Systems Research (CISR), a research group at the MIT Sloan School of Management suggests that an operating model is useful to guide IT investment decisions. IT investment must support the operating model.
Ross, Weill and Robertson summarized found that an organization with an operating model reported 31% higher operational efficiency, 33% higher customer satisfaction, and a 34% advantage in new product development. In the book "Enterprise Architecture as Strategy," they outline four operating models:
- Process standardization & integration
- Coordination – low process standardization but high process integration (Compare with allied strategy – where subsidiaries provide varied products to the same customers)
- Unification – both high standardization and integration (compare with integrated strategy)
- Diversification – businesses requiring low standardization and low integration (compare with holding company strategy)
- Replication – high standardization but low integration (Compare with Franchisees or Replicated Facilities of an Integrated Strategy)
Operating models inform the appropriate level of business process integration and standardization to deliver the organizations promises to stakeholders.
The operating model informs IT leaders about how various technical and business components should be designed and implemented to enable the chosen operating model:
|Decision Making Processes||X|
|Systems Component Technology||X|
Coordination and unification models benefit more from consolidated views of customer and data across the enterprise than do diversification and replication models.
