Modern System Analysis And Design Chapter 10 Business Documents 1. Form: A business document containing predefined data, with spaces for additional information to be filled in. Each form instance is typically based on one database record. 2. Report: A passive business document that contains only predefined data, used solely for reading or viewing. Reports typically aggregate data from multiple unrelated records or transactions. --- Types of Reports 1. Scheduled Reports: Reports generated at predefined intervals (daily, weekly, monthly) to meet the routine informational needs of an organization. 2. Key-Indicator Reports: Summarized reports that provide critical information on a recurring basis. 3. Exception Reports: Reports that identify data out of normal operating ranges, highlighting anomalies. 4. Drill-Down Reports: Reports that offer detailed information underlying the summary values found in key-indicator or exception reports. 5. Ad-Hoc Reports: Unplanned information requests that gather data to support non-routine decision making. --- Design Specifications 1. Design Specifications: Key deliverables and inputs for the system implementation phase, outlining how the system should be designed and operate. - Section 1 Design Specification (Narrative Overview): Characterizes users, tasks, the system, and environmental factors involved. - Section 2 Design Specification (Sample Design): Visual representation of the form as derived from coding sheets or form-building tools. - Section 3 Design Specification (Testing and Usability Assessment): Evaluation of testing and usability outcomes, focusing on consistency, sufficiency, accuracy, etc. --- Usability 1. Usability: An overall evaluation of how effectively a system supports a specific user to accomplish a particular task. Key characteristics include: - Speed: The rate at which users can complete tasks. - Accuracy: The correctness of the output or results achieved. - Satisfaction: The user's overall contentment with the system's performance and experience. --- Web Design Concepts 1. Lightweight Graphics: The use of small, simple images to enhance w
