Justification and need for full system testing must be made clear.
Q1.A scenario is a statement of assumptions about the operating environment of a particular system at a given time; that is, it is a narrative description of the decision-situation setting. What does a scenario describe, and what may it provide?
Q2.According to Simon (1977), most human decision making, whether organizational or individual, involves a willingness to settle for a satisfactory solution, "something less than the best." This is called satisficing. How does a decision maker go about satisficing?
, The effect of scope creep is a major cause of delays on most sotware development
project. As the Systems Analyst for the GCTU e-learning implementation project,
outline steps and strategies you would employ to keep the scope of the e-learning
system from growing and including new functions that should not be part of the system?

- A safety-critical system is one whose failure or misuse may cause human injury or death. Given that an EHR system can be considered to be such a system, which tasks associated with software implementation deserve special attention?arrow_forward______________ is a diagram used to document the processes of the current system or to provide a model of a proposed new system.arrow_forwardYou and your team have been hired to perform a system investigation for a fast food restaurant that wants to implement new tools and processes to improve its customer service. Currently, the restaurant has a poor reputation for not correctly filling customers orders and for taking too long to do it. Perform a functional decomposition to define the scope and basic requirements of such a system. Brainstorm some ideas to improve the situation, and choose one to pursue based on its technical, economic, legal, operational, and schedule feasibility.arrow_forward
- 1)Write a possible scenario that could be used to help design tests for the MHC-PMS case. Then create a test plan for the Scenario Testing. 2)What are the strategic options for legacy system evolution? When would you normally replace all part of a system rather than continue maintenance of the software?arrow_forwardi need the answer quicklyarrow_forwardWhat are the difficulties in analyzing a system? What are some of the components in examining a system to determine whether it has a high probability of success or is deemed unfeasible? What causes a system project to fail?arrow_forward
- In what ways does the analysis of a system provide difficulties? What are some of the aspects that go into evaluating a system to determine whether or not it is likely to be successful or if it is impractical? Why might an effort to create a system be unsuccessful?arrow_forwardIn order to establish a connection between the ideas of user engagement and change management in a software installation project, provide a list of the four main reasons why your involvement as a user of an information system is essential throughout the systems development life cycle.arrow_forwardHealthy Food is considering implementing a telephone system using the system development features supplied by Microsoft Access. They are not sure whether it can provide the kind of interface that would be needed and are also concerned about the possible response times of a system developed using Microsoft Access. Explain (i) how, with a made-up “Healthy Food example” and (ii) during what stage of a system development project , would prototyping be useful as a means of reducing this uncertainty.arrow_forward
- An auditor is preparing a systems development process audit for a software development company. The auditor has identified the following six control activities as sources of audit evidence: 1. Users’ involvement in the systems development process2. Systems design3. System authorization4. Pre-implementation testing5. Program code integrity6. Internal audit a.) For each control activity, what documents or evidence will the auditor expect from the software development company? b.) What other control activities would you add to the evidence list?arrow_forwardA gradual approach to implementing new functionality, beginning with a basic set, then adding more advanced functionality after users have had a chance to adjust to the new system is a good idea because: Group of answer choices Users can get new ideas for advanced functionality once they have a chance to use the basics of the new system. This approach allows for an iterative approach to be taken to fix issues and make improvements to the new system. It sets in motion “the journey” of continuous improvement and process redesign using the new system. All of the above.arrow_forwardLayered software architectural pattern is a widely used pattern. You are required to discuss the applicability of this pattern in the following situations: 1) when the environment is Continuously changing 2) when High performance of the application is important 3) when Ease of testing is important 4) when Ease of deployment is importantarrow_forward
