Measuring developer productivity: A clear-eyed view (Category Management)

Interesting. interview On the theme of developer productivity, which Kent Beck took from Abi Nod, Both gentlemen are respected people among developers.

• Kent Beck, author of XP (extrem programming), signatory to Agile Manifesto, adept TDD (test driven development). I was talking about him recently. play "Tidy First" and before that. detailed This latest book is "TIdy First." Abi Noda is co-founder and CEO of DX, an analytics platform to evaluate and improve developer productivity and experience. Abi is also a co-author of research on the Developer Experience that I talked about earlier: "DevEx: What Actually Drives Productivity" andDevEx in Action"

The interesting thing about this interview is that Kent Beck has always been a consistent critic of metrics around developer productivity, and Abi Noda builds on this business. And this is what they discussed.

1) Goodhart’s Law (Goodhart's Law) The interview emphasizes that when a metric becomes a goal, it loses its effectiveness – this is the basic idea of Goodhart’s law. This leads to the fact that excessive dependence on a single numerical metric can lead to a distortion of incentives, because of which teams will seek to “bypass the system” rather than actually improve the quality of work. Abi Noda knows this, so he has four metrics that balance each other: speed, efficiency, quality, impact. Separately, Abi notes three important points when implementing the developer productivity measurement system.

• Communicating and following through on being an ally to developers
• Never measuring metrics like diffs per engineer at the individual level - that's something we stipulate in our framework and build into our product
• Using it within this basket of metrics - developer experience is as important as speed, and quality balances both 2) Developer experience (developer) The focus is on creating a supportive and comfortable environment for developers. Rather than simply measuring results, the emphasis is on giving developers the tools, processes, and culture they need to succeed, which ultimately improves productivity and quality. 3) Using benchmarks (benchmarking) Abi Noda suggests using industry or domestic benchmarks as a benchmark to understand where the team is relative to best practices. However, it is emphasized that benchmarks should be adapted to the unique context of the team, as differences in project type, team composition and work culture require a flexible approach. These are very important remarks regarding benchmarking - if you compare warm with soft, you will not get meaningful results. 4) Implementing metrics (metricization) When designing and implementing productivity metrics, the emphasis is on a balanced approach that avoids focusing narrowly on quantitative outcomes. Best practices include identifying metrics that are empirically valid and using them as benchmarks for continual improvement rather than as goals in themselves. The general recommendation is to apply a reflexive and iterative process of developing metrics, taking into account feedback from developers and management.

In general, it turned out, to me, a great interview, where Kent and Abi went through the key pain points of measuring productivity and stayed with their own, agreeing that Abi with his platform does normal things, as well as with Kent’s skepticism about the misuse of metrics by most in the software development market.

P.S. I signed on. mailing From Abi Noda's GetDX platform, where you get good materials about the productivity of engineers. I recommend it.
