The F35 seems like a project management issue more than engineering. No one stopped the scope from creeping out of control as new tech and capabilities were added.

The problem with F-35 wasn't scope creep, it was the initial premise which operated under a mistaken belief that getting a single “do everything” airframe to maximize commonality would drive down unit cost, rather than driving it up through the conflicting needs of distinct missions.
