A budget described as generous can still be narrow for the work it expects.

Generous is a comparison, not a measurement. A figure can be larger than last year, larger than a rival’s, and still nowhere near what the actual task requires, and calling it generous makes it awkward to say so out loud. That is how projects end up staffed by goodwill, with the shortfall quietly paid in someone’s evenings.

Before accepting a number, work out what the job costs in hours, materials, and people, and compare that instead of comparing adjectives. If the gap is real, say it early and specifically. Later, it will look like an excuse rather than arithmetic.
