Answer to Question 1

Design extends modeling from conceptual to concrete. Logical modeling maps the concept of the product into identifiable building blocks without concern for specific technologies, while physical modeling translates the logical artifacts into engineering blueprints.
An example for a non-IS product would be building a car, which starts with a logical description that is independent of how it will be built and emphasizes its looks and features. This logical model later on is completed with a physical model that is a blueprint of how the car should be built.
An accounting information system needs a logical model of what it needs to accomplish and a physical model as how it will be built. Analysis results in a conceptual model that defines the what and the where of the product or the service. To decide how the product will achieve the goal, we need to create a workable solution. This is the task of design that adds the how to the what and the where of analysis.

FALSE
