User interface standards can be hard to use for developers. In a laboratory experiment, 26 students achieved only 71% compliance with a two page standard; many violations were due to influence from previous experience with non-standard systems. In a study of a real company's standard,developers were only able to find 4 of 12 deviations in a sample system, and three real products broke between 32% and 55% of the mandatory rules in the standard. Designers were found to rely heavily on the examples in the standard and their experience with other user interfaces.
This paper discusses the role of an information developer in defining application interface standards and ensuring compliance across all applications. An interface, such as an application screen or system-generated report, should be consistent to enhance ease-of-processing for the end users.
