McFarlan implemented a framework (1984) with which organizations can analyze their mix of existing, planned, and potential information systems. The framework, which can be implemented to any type of application, including e-commerce, can be saw as a four-cell matrix. Applications are classified into a collection(portfolio) of the following four categories:
Key Operational: Applications upon which the organization currently depends for success. (such as inventory control, accounts receivable, personnel duties.)
Strategic: Applications that are critical for future business strategy.(e-procurement extra net, enterprise resource planning).
Support: Applications that are currently valuable and desirable but not critical for future business success. (such as videoconferencing and multimedia presentations.)
High Potential: Applications that may be important in achieving future business success. (such as intelligent systems or human resource planning).
McFarlan's Portfolio Framework of purposes are to bring business people and IT specialists closer together and thus develop more efficient system.
