Final answer:
Philosophy is the discipline that does not directly contribute to contemporary approaches to information systems, whereas psychology, computer science, operations research, and economics all play integral roles in this field.
Step-by-step explanation:
The discipline that does not directly contribute to the contemporary approaches to information systems among the listed options is B. philosophy. Disciplines like psychology, computer science, operations research, and economics are integral to understanding the different aspects of information systems. Psychology helps in understanding user behavior and cognitive processes, computer science provides the technical foundation, operations research contributes to the optimization and efficiency of systems, and economics offers insights into market dynamics and the value of information.
Philosophy, while influential in providing a broader understanding of concepts such as reality, knowledge, and existence, does not directly deal with the pragmatic and technical aspects that constitute modern information systems design and implementation. Therefore, in the context of direct contributions to information systems, philosophy is the exception.
