In my view Tim's article outlines the many advantages of SaaS delivery model over the traditional design-make/buy software delivery model. The main advantages that all SaaS provider tout are the following:
- SaaS requires no large capital investment,
- SaaS has no maintenance,
- SaaS has low integration and customization cost, and
- finally SaaS has short pay-back period.
I think the data is interesting, but in my opinion the value of this data to SaaS community is that user community needs to be better informed and educated about SaaS.
