Answer to Question 2

The value chain model identifies specific, critical leverage points where a firm can use information technology most effectively to enhance its competitive positions. Exactly where can it obtain the greatest benefit from strategic information systems? What specific activities can be used to create new products and services, enhance market penetration, lock in customers and suppliers, and lower operational costs? This model views the firm as a series or chain of basic activities that add a margin of value to a firm's products or services. These activities can be categorized as either primary activities or support activities.
 Primary activities are most directly related to the production and distribution of the firm's products and services that create value for the customer. Primary activities include: inbound logistics, operations, outbound logistics, sales and marketing, and service.
 Support activities make the delivery of the primary activities possible and consist of: organization infrastructure (administration and management), human resources (employee recruiting, hiring, and training), technology (improving products and the production process), and procurement (purchasing input).
