This is only true to the extent that the IT department has complete control and is insulated from user opinion. That tends to result in choices like WebEx or the ever popular shadow IT option. This is especially true now that everyone is doing this and the odds approach certainty that if someone is having problems they’ll suggest switching to a different product they know works.

Given the number of IT people I’ve heard express concerns about UI quality and eventual cancellation even for enterprise purchases, it’s also far from a given that the IT department is just blindly pushing a product.
