CONSIDERING QUANTITY, QUALITY, AND STABILITY WHEN DELIVERING THE NEXT GENERATION OF YOUR DESIGN SYSTEM

Summary from the TLDR Design newsletter

Feature quality — usability, accessibility, performance, and consistency — starts high and stays high. The quantity of completed features resembles an “S curve” over time, accelerating gradually before flattening as the launch approaches. Feature stability increases throughout implementation, but reversals are common and expected to refactor things already made based on what was learned.
