SaaS for Enterprise Learning?

I have long though that there was a significant potential role for ASP or Software-as-a-Service learning solutions for large enterprise organisations, but I'm not sure whether the vendors really see this (beyond those that SaaS is their main offering anyway). Yes they get the fact that SaaS is a good approach to sub-Enterprise customers (mid-tier etc), and that it is a useful tactical tool for accelerating enterprise customers. But they don't seem to see it as the long term platform of choice for them, believing that privately hosted or behind the firewall are the likely options.

I'm not sure I agree. Tactical platforms have a habit of being more long term than originally envisaged - especially given the challenge with the strategic ducks lined up! I'm also unconvinced that the perceived cost of SaaS over the longer term is disadvantageous compared with fully-costed internal or externally hosted solutions. And you would seem to get much greater flexibility with SaaS, both in terms of commitment, and in terms of flexibility of service, compared with the detailed terms and conditions that a hosting service or internal IT department wants to impose.

I'm interested to know what you think ...
