1. One of the potential problems mentioned in this chapter with gathering information requirements by observing potential system users is that people may change their behavior when observed. What could you do to overcome this potentially confounding factor in accurately determining information requirements? The analyst could conduct the observations unobtrusively, so that the effect on the users’ behavior is minimized. This could be done using a confederate or by a hidden camera. The analyst could also brief the users on the observation so that the users will relax and behave naturally. For example, you can make it clear to users that they are not being evaluated and that the observations collected will not be associated with anyone individually. In addition, the analysts could perform multiple observations over time. This would tend to minimize the effects of aberrant behaviors. Alternatively, the analysts could supplement their requirements determination with additional data collection methods.

3. Suppose you were asked to lead a JAD session. List ten guidelines you would follow in playing the proper role of a JAD session leader. Students might suggest the following for the JAD leader: the JAD sessions should be off–site, the proper people should be invited to the JAD sessions, establish clear ground rules for the sessions, set and follow a clear agenda, distribute the agenda to all participants before the sessions, remain neutral on issues, make sure that everyone has the opportunity to participate, encourage people to be creative and break free of traditional ways of doing things, manage time effectively, and follow up with meeting notes.

...1. One of the potential problems mentioned in this chapter with gathering information requirements by observing potential system users is that people may change their behavior when observed. What could you do to overcome this potentially confounding factor in accurately determining information requirements? A great way to overcome this problem is to get an anonymous person to conduct the observation. Without the people having this knowledge, this will allow the system users to act normal. This would allow for accurate gathering of information. 2. Suppose you were asked to lead a JAD session. List ten guidelines you would follow in playing the proper role of a JAD session leader. I would make sure all the proper personal are going to be present. These being the users, managers, sponsor, system analyst, scribe and IS staff.

Time management is very important to this because the longer it takes the more expensive it will be. In order for the meetings to proceed smoothly, the proper tools have to be present. These tools are flip-chart paper, whiteboards, and audiovisuals. Communication is going to be very important in these meetings since everyone will have something to say about the systems, this being good or bad. I have to make sure everything stays on track and at the end of these meetings a solution is found for the problem. 3. What unique rules apply to......

Week 1 Problems and Exercises

...Problems and Exercises Week 1 Chapter 1 1. Why is it important to use systems analysis and design methodologies when building a system? Why not just build the system in whatever way seems to be “quick and easy?” What value is provided by using an “engineering” approach? It is important to use system analysis and design methodologies when building a system because it helps identify the problem to be solved and what the goal of the system should be. If you just started the fastest way you would most likely miss the reason for building it plus you may only create more problems. The value added is utilizing the time and resources you have most efficiently. By not using an engineering approach you risk too much waste. 8. How might prototyping be used as part of the SDLC? Prototyping can be used as a tool to help identify what users want from the system being designed. It aids the analyst in the SDLC process to help provide answers as to what users may want. Chapter 2 3. In the section on choosing off-the-shelf software, eight criteria are proposed for evaluating alternative packages. Suppose the choice is between alternative custom software developers rather than prewritten packages. What criteria would be appropriate to select and compare among competing bidders for custom development of an application? Define each of these criteria.

...Problem & Exercise Chapter 8 3. A report is meant for reading and information, so if a report is not properly put together then these things can happen: * listed with no page numbers then they can be shuffled and get out of order * putting the headings of the columns on every page (if not it is information overload & you will lose you place) * having incorrect information/data * missing one of the who, what, when, or where (software error) * data errors The consequences to these errors are: * the wrong decisions can be made * the data can given or received can be wrong * the outputs are wrong If the analyst can notice most of the errors as he is working on them so that it may be corrected then this can help keep the project of the report going without too many complications. Prototyping is very helpful when working on reports because the analyst is able to structure and refine the report before it is viewed by the mass majority without the consequences of errors. 4. The date does not specify when the report was generated; it does not give a revision date or code for any prior report versions, does not provide any meaningful information, there is not any page number listed, the spacing of the report information does not seem to be in place.

Business Systems Analysis Problems and Exercises

...Problems and Exercise 1. Why is it important to use systems analysis and design methodologies when building a system? Why not just build the system in whatever way seems to be “quick and easy?” What value is provided by using an “engineering” approach? It is a good idea to use a system analysis and design methodologies when building a system because it creates a system that creates solutions for the entire business unit, instead of wasting resources patching the issues as they come. 8. How might prototyping be used as part of the SDLC? Prototyping can be used within the SDLC methodology by falling into the testing phase of the system. Since prototyping is creating a version of the software, it could be used to test for bugs, and make upgrades as necessary. 3. Suppose the choice is between alternative custom software developers rather than prewritten packages. What criteria would be appropriate to select and compare among competing bidders for custom development of an application? Define each of these criteria. • Cost – Comparing the cost of developing the same system in-house to cost of purchasing. • Functionality – if the software will meet the function requirements. • Vendor Support – Refers to whether the vendor can provide support, and how much. • Viability of Vendor – How reputable the vendor is, and how long they will continue to be in business. • Flexibility – Refers to how easy it is for you or vendor to customize the package • Documentation –......
