About Spotlight on Productivity Engineering
Spotlight on Productivity Engineering (SpotEng) is an independent publication about productivity engineering: the discipline of improving how engineering organizations deliver software by fixing systems (tooling, processes, measurement, and team health) rather than judging the people inside them.
It was launched in November 2024 by Guy Levin, VP of Productivity Engineering at ZoomInfo, where he leads the organization responsible for CI/CD, developer experience, quality engineering, internal platforms, and AI in the SDLC. That includes the part most companies get wrong: building the measurement systems that connect engineering work to business outcomes.
Before this role he was Senior Director of Engineering at ZoomInfo, leading the SalesOS platform and ten full-stack teams, and spent a decade at Philips Healthcare in architecture and engineering leadership roles on genomics, oncology, and clinical imaging platforms.
Over 20 years in, from the Israeli Air Force to startup CTO to VP: everything published here comes from practicing the discipline, not just writing about it.
What you'll find here
The writing is research-driven and practical, aimed at engineering leaders and productivity engineers who need answers that survive contact with a real organization:
- Measurement that can't be gamed. How to combine DORA, SPACE, and developer satisfaction into metrics that improve systems instead of ranking people. Start with Beyond Lines of Code.
- Technical debt as an economic problem. Quantifying what debt actually costs and how AI changes the economics of paying it down. See Tech Debt Explained.
- AI's real impact on productivity. What breaks when commits and lines of code inflate automatically, and what to measure instead. See How AI Disrupts Productivity Measurements.
- AI, LLMs, and the changing SDLC. Hands-on coverage of AI in software development: coding assistants and agents in the enterprise, large and small language models (LLMs and SLMs), and how the engineer's role shifts from writing code to orchestrating it. Start with AI Coding Assistants in the Enterprise and The Future of Software Engineers in the AI Era.
- Team health as an engineering discipline. The Psychological Productivity Engineering framework for measuring the human side with the same rigor as the pipeline.
