Question 1: Having an adequate data model to serve specific business needs of an organization is important. Evaluate the need for denormalization within an organization. Provide at least three examples that prove denormalization is useful to data consumers. Using a data-modeling checklist can help database developers design efficient data repositories. Suggest at least two possible scenarios that could take place if one of the steps in the data-modeling checklist (table 6.7 in Chapter 6 of the textbook) is missed.

Question 2: Your design team presents a project to you, in which most inputs seem to have about a 1.5-second delay before a response. The lead designer has decided this response is acceptable. Analyze response-time models and decide if the response time in the presented project is acceptable. Explain why it is or is not. Evaluate the importance quality of service has to designers. Choose two areas discussed in the textbook you would focus your attention to ensure quality of service for a team of designers that you were managing. Justify your choices.

Question 3: Error messages are a key part of an overall interface design strategy of guidance for the user. Discuss strategies to ensure integrated, coordinated error messages that are consistent across an application. Choose the one topic covered in Chapter 11 (error messages, non- anthropomorphic design, display design, window design, and color) that creates the biggest challenge to achieving balance between function and fashion. Support your response.
