Spolsky stresses that the design of user interfaces is, at essence, an enterprise that is best undertaken with rational, methodical thought. No special creative or artistic talents are needed to design a user interface of quality. Instead, he advises, simplicity and consideration for the potential needs and desires of the user are the ingredients for creating a useful interface. Viewing the user as a logical person who expects the interface's responses to his actions to match his expectations and act in accordance with his intuition. The interface, in Spolsky's view, is to remain unobtrustive and responsive to the user.
Although not all of the content in User Interface Design for Programmers pertained to this project, given the nature of this interface and guidance related to Microsoft products, much of his material was useful in the construction of the interface. Spolsky's emphasis on simplicity and ease of use was the driving factor behind the final version of the interface, which uses four colors--white, green, gold, and blue (for the background)--and remains uncluttered by superfluous elements.
