What ever happened to “scaling to capacity”?

Scaling to capacity is one of the cornerstones of Agile. The Agile Manifesto stipulates a dozen principles and one of them reads: “Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale.” It is fair to say that our bias nowadays has increasingly shifted to even shorter time scales, as compared with 2001.

By gathering feedback and measuring progress in (very) short cycles, we mitigate and reduce schedule uncertainty. The shorter your cycles, the more o them you will run in the same amount of time. Hence, you will get more “practice” assessing progress. With experience, teams “know” how much they can take on (commit to) for the next iteration (“Sprint” in Scrum).

It is only natural for managers to be “impatient”: it is their job to manage resources (mind you: not just “people”) in order to achieve the best possible results in the shortest amount of time. So “pushing” for results is management’s understandable bias. Submitting reasonable requests is fair, and I guess it is only human to be fallible, and sometimes cross the line from fair to unreasonable.

There’s a reason why we strive for a sustainable pace, another essential component of the Agile Manifesto. It’s in nobody’s interest (management the least) to accrue technical debt or burn out people. I’ve written before about technical debt (like: here on documentation and here on “fudging”, and my post on quick & dirty has drawn more traffic than any other, I believe), and so have many others since 1992 when Ward Cunningham coined the term.

When undue schedule pressure causes absenteeism, more errors, and unhealthy staff turnover, this obviously harms the team’s capacity to deliver features at a high and steady pace. Scaling to capacity implies respecting people’s boundaries, and acting accordingly. You just can’t fit 10 lbs of potatoes in a 5 lbs bag…
