The Craftsmanship Ceiling

Two lines track the profit you keep as the amount of work you deliver rises. The green productized line keeps climbing as volume grows, while the red dashed all-custom line rises a little, hits a ceiling in the middle, then falls. The shaded gap between them widens on the right. The flexibility that wins deals early becomes the extra work that kills growth later, so the fix is to package the routine 80% and save true custom work for the 20% that needs it.
