Survey: AI-generated code raises debugging time, failure rates and comprehension gaps
A Coleman Parkes survey of 300 senior engineering leaders commissioned by Undo found that AI coding agents speed code generation but shift the main bottleneck to debugging, comprehension, and maintenance — respondents report averaging 9.8 hours/week producing code versus 16.9 hours/week debugging, 35% of AI-generated code reaches production before teams fully understand it, and 80% say agents struggle with complex problems in mission‑critical C/C++ codebases.
KEY POINTS
- A Coleman Parkes survey of 300 senior engineering leaders commissioned by Undo found that AI coding agents speed code generation but shift the main bottleneck to debugging, comprehension, and maintenance — respondents report averaging 9.8 hours/week producing code versus 16.9 hours/week debugging, 35% of AI-generated code reaches production before teams fully understand it, and 80% say agents struggle with complex problems in mission‑critical C/C++ codebases.
- The result matters because faster code generation can increase debugging, failures, and operational risk, meaning AI tools may not improve overall release velocity without new practices and tooling.
