Dr. Yuki Tanaka, PhD

Biography

Dr. Yuki Tanaka holds a PhD in Information Systems from the Massachusetts Institute of Technology, where his doctoral research examined how enterprise organisations design and apply evaluation frameworks for software selection decisions. His dissertation addressed a specific and persistent problem in enterprise technology procurement: the structural gap between the claims that vendors make about their products and the documented evidence that enterprise buyers can independently verify. The research produced a framework for classifying that evidence by source type, interpretive weight, and expiry risk — a framework that subsequently became the foundation for his applied work in industry and, later, for the evidence classification system at Brightfield Research.

Before his doctorate, Tanaka completed an MS in Computer Science at Carnegie Mellon University, where his graduate work focused on software systems design and the computational dimensions of large-scale data evaluation. The combination of technical training in systems design and subsequent academic specialisation in information systems gave him a distinctive research lens: he approaches evaluation methodology as both a technical design problem and an epistemological one. The question is not only how to collect and process evidence, but how to specify what it means for evidence to be reliable, complete, and fairly weighted against competing claims.

After completing his doctorate, Tanaka joined IBM Research as a research scientist, where he spent several years publishing on technology adoption frameworks, enterprise software evaluation methodology, and evidence quality classification. His peer-reviewed publications appeared in MIS Quarterly, Information Systems Research, and the Journal of MIS — the leading journals in the information systems field. His IBM Research work produced documented frameworks for assessing the quality of evidence used in enterprise technology adoption decisions, and established his reputation as one of the few researchers working at the intersection of information systems theory and practical enterprise evaluation methodology. He joined Brightfield Research in 2026 to apply that work to the specific challenge of building a public-facing research publication with rigorous, inspectable evidence standards.

Role at Brightfield Research

As Research Director, Dr. Tanaka is responsible for the evidence classification standards that govern all research outputs produced by Brightfield Research. The seven-class evidence framework used in every Brightfield publication — which classifies evidence by source type, interpretive weight, and expiry risk — was developed and is maintained under his oversight. He sets the criteria for what qualifies as evidence in each class, what interpretive weight each class carries, and what labeling and qualification requirements apply when evidence from a given class is used to support a factual claim in a published output.

Tanaka also governs research quality criteria across all categories covered by the publication. When a new category is added to the coverage scope, he is responsible for assessing whether sufficient public evidence exists to support research that meets the evidence framework requirements, and for designing the evidence collection protocol for that category. He holds authority over methodology documentation: the documented methodology published at brightfieldresearch.com/methodology reflects the standards he has specified and maintained. Any change to the evidence classification system, quality criteria, or methodology documentation requires his review and sign-off before publication.
