Frontier AI performance across the business disciplines: a case-grounded benchmark of knowledge work and analytical reasoning

2026-07-17

AI Summary

Current AI benchmarks struggle to evaluate the higher-order cognitive capabilities required of large language models in white-collar knowledge work, particularly in judgment under subjectivity and uncertainty, as well as strategic reasoning. This work proposes BusinessCaseBench—the first quantifiable evaluation benchmark grounded in the case-based pedagogy of top-tier business schools—featuring hundreds of real-world scenario questions spanning 18 business disciplines, accompanied by expert-developed scoring rubrics. The framework systematically assesses model performance in core competencies such as structured analysis, trade-off evaluation, and decision-making. Experimental results demonstrate that state-of-the-art large language models have achieved substantial score improvements on this benchmark, nearing or reaching entry-level professional proficiency within just two years, thereby validating the benchmark’s effectiveness and forward-looking design.

Abstract

Large language models (LLMs) are improving rapidly as reflected in benchmark scores, yet these AI benchmarks largely test capabilities such as factual recall, narrow question answering, mathematical problem-solving, and coding and agentic tool-use. What remains poorly measured is AI progress on the analytical knowledge work white-collar professionals perform daily, including synthesizing complex information, exercising judgment under uncertainty and incomplete information, applying strategic and adversarial thinking in multi-stakeholder settings, weighing trade-offs, and producing defensible, structured analyses. This gap is even more pronounced for subjective components of such work, where success can be challenging to define. The "case method" form of education practiced by top business schools provides a natural foundation for addressing this measurement gap, and we construct BusinessCaseBench, a benchmark spanning hundreds of questions drawn from business cases across eighteen disciplines, each paired with a grading rubric derived from the expert-written instructor case solution. On BusinessCaseBench, frontier AI models already score highly against instructor rubrics, and capability within one model family improves substantially over two years. These results provide strong evidence that AI performance on this class of work is already high and rapidly improving, with implications for business schools, where case pedagogy trains undergraduates and MBAs in this kind of analytical reasoning, and for entry-level professional roles, where such skills have historically anchored early-career work.
