Part 1: The Hidden Costs of "Doing It Yourself"
Without a centralized system, teams accumulate technical debt. Here is where the money is leaking from.
1. The Rework Tax
Every time a component is built from scratch, it introduces a risk of inconsistency. That risk forces design and engineering to revisit the component six months later. In a team of 10, this "rework tax" can consume 15–20% of total engineering hours.
2. The Inconsistency Tax
When you have 50 variations of a "Primary Button," your UI loses brand integrity. Users subconsciously trust brands less when they feel disjointed. This leads to a 5–8% drop in conversion rates for e-commerce brands, which is a direct financial loss.
3. The Onboarding Drag
New hires spend weeks figuring out where things are in Figma and how to implement them in code. A mature design system can cut this ramp-up time by 40%, getting contributors to productive status faster.
