It all depends. From what the parent posted, the issue was the software and hardware combination didn't work. If this was a 'known' issue and it was sold anyways then this is definitely something within the sales organization. It perhaps was a 'known' to the parent but never communicated out to the management or sales staff. However want to point out that the purpose of a sales organization is to sell. typically a sales organization will sell every and anything to the client. It is normal to sell features that are not implemented, or configurations that are problematic.
