Compare and contrast the effectiveness of classic models

Imagine you are managing a design project that will create an interface for automobile mechanics. The interface would be used by the mechanics to look up various fixes and parts for any number of makes or models of automobiles that may come through their garage. Decide what usability measures would be most motivating when designing this interface and describe the unique challenges you would have to plan for when designing an interface for an automotive repair shop. Use supporting evidence to support your response.

Physical, cognitive, perceptual, personality, and cultural differences introduce challenges when designing universally usable products. Choose one area from the list above and describe why it is the biggest challenge to overcome when creating universally usable designs. Support your response.

Early computers were only usable by experts with strong technical knowledge. Examine how interactive systems have changed throughout the years to accommodate average users and describe two advantages and two disadvantages associated with these changes.

Examine two articles you selected on universal usability and discuss one topic of interest that was addressed.

The proper implementation of a database is essential to the success of the data performance functions of an organization. Identify and evaluate at least three considerations that one must plan for when designing a database.

Suggest at least two types of databases that would be useful for small businesses, two types for regional level organizations and two types for internationally wide companies. Include your rationale for each suggestion.
