Velocity Is a Shadow; Throughput Is Reality

Image
In the previous post, we argued that estimation is a smell—a signal that teams are compensating for unmanaged uncertainty. Velocity, as a direct descendant of estimation, inherits that smell. Scrum reminds us that the purpose of a Sprint is to produce an *Increment of value* , not to consume a predetermined number of points. Velocity measures effort expended inside the team. Customers, however, experience outcomes: features delivered, bugs fixed, and capabilities unlocked. No customer has ever benefited from a higher velocity. Why Velocity Persists Velocity survives because it is visible, numeric, and easy to chart. It gives leaders something to point at and teams something to optimize. Unfortunately, that optimization rarely aligns with value delivery. When a measure becomes a target, it ceases to be a good measure. When velocity becomes important, teams respond predictably. Estimates inflate. Stories are sliced to satisfy point targets rather than user needs. Lower-risk, lower-valu...

Estimation is a Smell

Image
Part two in the Agile Engineering: Rhetoric vs Reality series. Agile teams frequently assert that they value outcomes over outputs, learning over prediction, and adaptability over rigid plans. Yet in practice, many teams devote a disproportionate amount of time and emotional energy to debating whether a piece of work is a 3 or an 8 . This tension reveals a persistent gap between Agile rhetoric and Agile reality. This post advances a simple claim: when estimation becomes a focal point of contention, it is a smell . Not because estimation itself is inherently flawed, but because prolonged debate over story points often signals avoidance of deeper issues—namely uncertainty, risk, and value delivery. Estimation and the Illusion of Precision Story points were originally introduced as a lightweight, relative mechanism to support short-term planning under uncertainty (Schwaber & Sutherland, 2020). They were never intended to function as precise measurements of effort or productivity. Howe...

Agile Isn’t Broken — We Just Stopped Practicing Engineering

Image
Agile didn’t break engineering; it exposed where we quietly stopped doing it. Agile was designed to shorten feedback loops and surface risk early. But in many teams, it became a substitute for engineering discipline rather than a framework that depends on it. Ceremonies scaled easily—standups, sprints, retrospectives—while harder practices that require deliberate time and technical ownership slowly eroded. Infrastructure and database engineering are where this erosion shows up most clearly. Practices like  intentional schema design ,  explicit migration planning , and  backward-compatible data changes  often gave way to “we’ll fix it in a later sprint.” Database indexes are added reactively instead of modeled up front. Query performance is discovered in production rather than load-tested in staging. Stateful systems demand careful coordination and deep understanding, yet Agile workflows often assume everything is as malleable as stateless application code. The result...

Why I’m Writing About Engineering in 2026

 Software engineering moves quickly, but the problems teams struggle with tend to repeat. Every few years we adopt new tools, frameworks, or processes that promise speed and simplicity. Some deliver real value. Others quietly replace hard engineering work with ceremony, abstraction, or optimism. As we head into 2026, it feels like a good moment to pause and reflect on which practices have endured—and which ones we may have let slip. Over the coming weeks, I’ll be writing about a few recurring themes I’ve seen across teams and systems: how Agile practices interact with engineering discipline, why databases and infrastructure decisions shape products for years, and what it actually takes to run reliable systems in production. These posts won’t focus on tools or trends. They’ll focus on the unglamorous work—design, testing, operational awareness, and feedback loops—that quietly determine whether teams can move fast  and  safely. The goal isn’t to prescribe a single “right wa...

Tariffs are bad for you.

Headlines from today state that the new Trump administration will put a 25% tariff on imports from Mexico, and Canada. Additionally, a 10% tariff on goods imported from China.  A tariff is a fee charged by the Federal government on goods coming into the country. That fee is paid by the importer, not the exporter.  For example, Target wants to sell PlayStation in their stores, so they purchase them from Sony, who builds these in China. Target receives the shipment of PlayStations, where they will be charged the tariff. Target pays the tariff to the Government to receive these goods.  Target then must decide how to recoup the additional fees. They can either choose to eat the cost and reduce their revenue, or they can increase the selling cost. The outcome is a combination of the two.  As a result, consumer prices, specifically for food and cars are going to go up. And businesses lose money by having to pay tariffs and selling few items.   For th...
