Civil servants are quite capable of understanding other development methodology. Civil servants actually involved in software development are often constrained by legal and regulatory regimes which no one in a substantively technical role has significant input into, which mandate procurement, risk-management, and approval processes which essentially mandate a high-level flow very similar to a completely non-iterative, cartoonish mockery of waterfall, and to the extent that they can attempt to implement more effective processes, they must do so within those constraints.
