Answer to Question 1

Although any written document can provide insight into the future system requirements, four documents were specifically mentioned in the chapter. They are the written work procedure, business form, report, and current system documentation. The written work procedure describes how a particular job or task is performed and identifies the data and information requirements needed by the job. Business forms are important because they can demonstrate what data flow in or out of a system and which are necessary for the system to function. Reports are beneficial because they provide information about system output. The fourth type of documentation, current system documentation, refers to documents that describe the current information system. This type of documentation can provide insight concerning how the systems were built and how they work.
