Ch. 4 Systems Analysis questions and answers latest updated What five questions typically are used in fact-finding? What other questions does the Zachman Framework include? Isthe addtional questions important? 1. The five fact-finding questions are the familiar Who, What, Where, When, and How. Who - Who performs each of the procedures. What- What is being done, and what procedures are being followed. Where - Where are the operations being performed. Where they could be performed. When - When is the procedure performed, why is it being performed at this time, and is this the best time. What is a sytems requirement, and how are systems requirements classified? 2. A system requirement is a characteristic that must be included into the system as it is being developed to satisfy all business requirements so it can satisfy the end user. They can be categorized into outputs, inputs, processes, performance and security. What are JAD and RAD, and how do they differ from traditional facr-finding methods? 3. JAD - Joint Application development, this is a popular fact finding technique that brings users into the development process as active participants. RAD - Rapid application development, this is a team based technique that speeds up information systems development and produces a functioning information system. The primary advantage is that the systems can be developed more quickly with the significant cost savings. What is total cost of ownership (TCO)? What costs often are understandable? 4. TCO is where system developers must identify and document indirect expenses that contribute the total cost of a system. Indirect costs are underestimated Provide three examples each of closed-ended, open-ended, and range-of-response questions. 5. Open-ended questions encourage spontaneous and unstructured responses: such as "How is the task performed?", "What are the users saying about the system?", "How are the checks reconciled?" Close-ended questions limit or restrict the response. Three examples: "How many computers do you have in this department?", "How many hours of training does a clerk receive?", "How many customers ordered products from the website last month?" Range of response questions are close ended questions that ask the person to evaluate something by providing limited answers to a specific response on a numeric scale. Three Examples: "How would you rate the company's security system?", "On a scale of 1 to 10 how effective was your training?" What are three types of sampling? Which one would you use to analyze data input errors? 6. Three Examples of sampling: Systematic - selects every tenth person for evaluation. Random - this is done randomly Stratified - select five customers from each four postal codes. What is the Hawthorne effect? how various changes in the work environment would affect employee productivity. What is a functional decomposition diagram (FDD) and why would you use one? Explain how to create an FDD. functional decomposition diagram (FDD) is a top down representation of a function or process. You would use one when you are at several stages of the development process. What are agile methods? Are they better than traditional methods? Why are why not? 9. Agile method - is the attempt to develop a system incrementally, by building a series of prototypes and constantly adjusting them to user requirements. Yes they are better than traditional methods because they are for planning and development as well as deliver and improvement of a system To what three different audiences might you have to give a presentation? 10. The three different types of audiences would be Senior manager, project manager, and team leader. For the senior manager you would have to give short descriptions of the existing IT systems and a short description of new and improved systems. As for project manager you should give the a very detailed description of the project. And a team leader would be giving details of a current process in progress. The hardest would have to be to the project manager since it has to be very detailed and thorough of the project as a whole. As well as provide details about total cost of the system.
