You 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.
A preliminary evaluation of software packages and vendors begins during the __________ phase when the two or three strongest contenders are identified. a. system investigation. b. system design. c. system analysis. d. feasibility analysis.
Suggest three usability measures that can be directly used to produce a practical evaluation of a system. Keep the goals of efficiency and satisfaction in mind with these measures.
Consider three techniques to specifying system requirements throughout the analytical process and compare and contrast their results.Which situations, in your view, do each strategy's advantages outweigh its disadvantages?What are some of the disadvantages of each technique?How would you go about determining which strategy to use?
Is it possible to identify the four types of feasibility that need to be evaluated? What's the deal? the system's viability as a result of the research, analysis, and What are the different stages of the design process?

Investigate three distinct methods for defining system requirements: the traditional, the contemporary, and the radical. Analyze the results.When is the best moment to use each of the several strategies you compared?What are the drawbacks to each method?Suppose you had to choose only one method to employ.
The classic CoSQ model classifies quality costs into four (4) subclasses: prevention costs, appraisal costs, internal failure costs, and external failure costs. Compare and provide examples of each subclass of costs. Both the classic and the extended software quality models assign costs to two main classes: costs of control and costs of failure of control. Explain the nature of each class.
