You may scarcely discover a extra controversial and hotly contested subject than metrics of software program growth productiveness. Some suppose the notion of measuring productiveness in any respect is an insult whereas others suppose it may be boiled down to only the strains of code produced.
Naturally, each these extremes are incorrect. And but the “proper” reply stays elusive.
Enter McKinsey. The Massive 4 consultancy made a good few enemies when it stated sure, you possibly can measure developer productiveness. Its framework under amalgamates two of the preferred present frameworks, DORA and SPACE, with extra opportunity-focused metrics.
Many will not be enthused. The critics embody Dave Farley, previously head of software program growth for low latency FX and crypto alternate LMAX Ltd. He says he is a fan of one of many metrics used, DORA, which has a concentrate on outcomes over the method. Nevertheless, he likens the distinction between DORA and different metrics to “the distinction between astronomy and astrology.”
Farley refutes the preoccupation with particular person growth metrics and says, “being good in how we construction and manage our work is far more necessary than the extent of particular person genius or in any other case within the group.” He references a now historical ebook of essays on software program engineering, The Legendary Man Month, and its concept that “9 ladies cannot make a child in a single month.”
Kent Beck, ex-fellow at payroll infrastructure fintech Gusto, and Gergely Orosz, previously an engineering supervisor for Uber’s funds platform and beforehand developer on JPMorgan’s fairness derivatives desk, additionally disagree with the McKinsey methodology. Their conclusions are that the report is “absurdly naive,” and would “do much more hurt than good” to corporations that implement it.
They recommend alternate options. – Concentrate on particular person engineers, hoping to watch and enhance their very own productiveness. They set builders a problem to “solely have one crimson check at a time when utilizing check pushed growth,” and “set a objective to merge a pull request each day.”
At a enterprise stage, they recommend a efficiency metric of “not less than one customer-facing factor per group, per week,” whereas rewarding “enterprise influence.” Although the previous sounds straightforward, they are saying it “in follow could be very arduous to realize.” The latter is much more ambiguous and summary than productiveness itself, however they are saying the objective is that it “incentivizes software program engineers to know the enterprise.”
Are these builders making a fuss over nothing? Or is the McKinsey report a foreboding signal of what is to return on this planet of engineering? Tell us within the feedback.
