English to French Other Idioms / Maxims / Sayings

There’s a level of frustration because service people come up with service ideas, we say yes you can do this with IMS, but they can also do it more cheaply with an old stovepipe solution… so they choose the latter. Really, [an internal] head-banging exercise is required. These vertically integrated solutions e.g. for PoC will now be difficult to migrate, so it’s very short-sighted.

pour "stovepipe", je pense spontanément à "de derrière les fagots", mais je ne sais pas si c le sens réel.

une bonne vieille solution "tuyau de poêle", ça le fait ? :)
Merci !
