In this episode of the Tech Leadership Deep Dive, your hosts -Marco and Raphael - dig into what “tech debt” really looks like in the real world, why it quietly builds up, and how it can eventually slow (or even sink) a company if it’s not actively managed. A few highlights that stood out: ➡️ Tech debt shows up as “we’re suddenly slow”: shipping goes from multiple deploys/day → weekly → monthly, QA cycles get painful, and every change feels risky. ➡️ It impacts hiring: strong engineers don’t get excited about joining teams stuck on outdated frameworks and brittle systems. ➡️ It increases security risk: old dependencies and unpatched runtimes expand your attack surface - often until something breaks publicly. ➡️ Upgrades become projects: the longer you delay maintenance (framework versions, libraries, architecture decisions), the more expensive and disruptive it becomes later .➡️ Good management makes it visible: using DORA/Accelerate-style metrics (lead time, deploy frequency, etc.), tracking shortcuts via architecture decision records, and labeling work in Jira helps quantify where time goes (new product vs. “keeping the lights on”). ➡️ The key is communication: tech leaders need to translate “tech debt” into business language (risk, speed, cost, capability), not just engineering jargon-and negotiate tradeoffs explicitly when shortcuts are necessary. The core message: some tech debt is inevitable, but unmanaged tech debt compounds-like interest-and eventually limits speed, safety, and talent. # References ## Books ### Accelerate: The Science of Lean Software and DevOps - **Authors:** Nicole Forsgren, Jez Humble, and Gene Kim - **Website:** [IT Revolution — Accelerate](https://itrevolution.com/product/accelerate/) ## Concepts ### DORA Metrics (Lead Time, Deployment Frequency, Change Failure Rate, Mean Time to Restore) - **Originators:** Nicole Forsgren, Jez Humble, Gene Kim and the DORA (DevOps Research and Assessment) team — now part of Google Cloud - **Website:** [dora.dev](https://dora.dev/) ### Architecture Decision Records (ADRs) - **Website:** [Architectural decision - Wikipedia)](https://en.wikipedia.org/wiki/Architectural_decision) ### Technical Debt Quadrant (Deliberate/Inadvertent × Prudent/Reckless) - **Originator:** Martin Fowler (2009) - **Website:** [Martin Fowler — Technical Debt Quadrant](https://martinfowler.com/bliki/TechnicalDebtQuadrant.html)
