Features drag, releases break things, and nobody can explain why. I find the structural problems and organize the way forward. See my approach Case studies 0x01 // the problem 02 The Problem Frontend complexity doesn't announce itself. It piles up quietly until shipping anything feels like a fight. [01] Features take longer than they should Change one thing, five other places break. What should be a half-day task turns into a multi-day ordeal, and nobody can explain why.
