Perhaps. Mercedes did employ a non-traditional solution in the DDRS. That alone pushed the rules and somehow they kept it. So I don't think it's the ides department where they struggle - it's the group working together for the same goal.
All the components on the Red Bull worked together to achieve one thing - corners. The partnership with Renault also worked towards that same goal. The other departments all kicked in with flexible this, holes in that, secret adjustments on this, rubber this, tunnel that - all for the same goal. So you had every single person developing parts to further push the one same direction.
Mercedes had a good idea - but then the entire team all went their separate ways - tyres this way, engine that way, aero this way, chassis that way - and it's this part where Mercedes have failed and will continue to fail. That's a leadership problem and I daresay an underlying work ethic problem too.
The W04 has schizophrenia in it's DNA. Solve that and you're on track to compete and win.
