In the 'ideal' case things mostly happening on schedule is a good sign because it means both that the people doing the doing are productive and reliable and the people trying to plan have a decent sense(whether personally, or by knowing what they don't know and where they can get an honest assessment and doing so) of how long things are going to take; whether there's something useful that can be added or whether forcing some mythical man-month on the people already working on it would just be a burden; keeping an eye on whether there's anything in the critical path that is going to disrupt a bunch of other projects, and so on.
If you start losing your grip on the schedule, that fact alone doesn't tell you whether your execution is dysfunctional or your planners are delusional, or some combination of the two; but it's not a good sign. Unhelpfully, the relationship between how visibly the gantt charts are perturbed and how big a problem there is is non-obvious(a company whose execution is robust but whose planners live in a world of vibes-based theatre and one whose execution is dysfunctional and crumbling and whose planners are reusing estimates from the time before the rot set in might blow a roughly equal number of deadlines; despite one having mostly a fluff problem and one probably being in terminal decline); but it's never a good sign.
