AI productivity gains vary widely by task complexity, report finds

A 2026 report from DORA, referencing Stanford University research, indicates that AI tools can achieve productivity gains of 35-40% on straightforward, new software development tasks. However, these gains diminish significantly to 10% or less when applied to complex, existing codebases, which constitute a large portion of production software. AI

IMPACT AI's effectiveness in software development is highly dependent on task complexity, with significant limitations on legacy codebases.
