I'm just back from argument on a government contractor defense matter involving a military trainer aircraft. Central to the debate was the level of detail to which the "reasonably precise specifications" of the Boyle test must reach. If taken too far, it seems requiring the government to review and approve everything down to the last rivet, bearing and bracket will put the GCD out of reach in too many cases, and thus raise the cost of government contracts, chill bidding or cause contractors to invite the government to micro-manage more than either party would otherwise want.
The cases make clear that only the "design feature in question" need be the subject of the "reasonably precise specifications," but that the "specific defect alleged" need not have been reached. Otherwise, the cases are largely specific to their own facts and not entirely helpful.
The court also questioned the distinction between performance and design specifications in the Boyle test context. That's also not a distinction discussed much in the GCD cases.
I'm interested in our membership's experience with these issues and any links to related resources.
