                                            Output Design Objectives

                                            Because useful output is essential to ensuring the use and acceptance of the information system,
                                            there are six objectives that a systems analyst tries to attain when designing output:
                                              1. Designing output to serve the intended purpose
                                              2. Designing output to fit the user
                                              3. Delivering the appropriate quantity of output
                                              4. Making sure the output is where it is needed
                                              5. Providing the output on time
                                              6. Choosing the right output method

                                            Designing Output to Serve the Intended Purpose
                                            All output should have a purpose. During the information requirements determination phase of
                                            analysis, a systems analyst finds out what user and organizational purposes exist. Output is then
                                            designed based on those purposes.
                                               You will have numerous opportunities to supply output simply because an application permits
                                            you to do so. Remember the rule of purposiveness, however: If the output is not functional, it should
                                            not be created because there are costs of time and materials associated with all output from a system.

                                            Designing Output to Fit the User
                                            With a large information system serving many users for many different purposes, it is often dif-
                                            ficult to personalize output. On the basis of interviews, observations, cost considerations, and
                                            perhaps prototypes, it will be possible to design output that addresses what many, if not all, users
                                            need and prefer.
                                               Generally speaking, it is most practical to create user-specific or user-customizable output
                                            when designing for a decision support system or other highly interactive applications such as
                                            those using the Web as a platform. It is still possible, however, to design output to fit a user’s
                                            tasks and function in the organization, which leads us to the next objective.

                                            Delivering the Appropriate Quantity of Output
                                            Part of the task of designing output is deciding what quantity of output is correct for users. A useful
                                            heuristic is that a system must provide what each person needs in order to complete his or her work.
                                            This answer is still far from a total solution because it may be appropriate to display a subset of
                                            that information at first and then provide a way for the user to access additional information easily.
                                               The problem of information overload is so prevalent that it is a cliché, but it remains a valid
                                            concern. No one is served if excess information is given only to flaunt the capabilities of the
                                            system. Always keep the decision makers in mind. Often they will not need great amounts of
                                            output, especially if there is an easy way to access more via a hyperlink or drill-down capability.
                                            Making Sure the Output Is Where It Is Needed
                                            Output is often produced at one location and then distributed to the user. The increase in online,
                                            screen-displayed output that is personally accessible has cut down somewhat on the problem
                                            of distribution, but appropriate distribution is still an important objective for a systems analyst.
                                            To be used and useful, output must be presented to the right user. No matter how well designed
                                            reports are, if the pertinent decision makers do not see them, they have no value.

                                            Providing Output on Time
                                            One of the most common complaints of users is that they do not receive information in time to make
                                            necessary decisions. Although timing isn’t everything, it does play a large part in how useful output
                                            will be. Many reports are required on a daily basis, some only monthly, others annually, and others
                                            only by exception. Using well-publicized, Web-based output can alleviate some problems with the
                                            timing of output distribution as well. Accurate timing of output can be critical to business operations.

                                            Choosing the Right Output Method
                                            Choosing the right output method for each user is another objective in designing output. Much
                                            output now appears on display screens, and users have the option of printing it out with their
