Make as if you are an IT admin and have to install a CRM app like SalesForce for your users.
In this case, SaaS (software as a service) can be viewed as accessing the application directly through your web browser through purchasing of a subscription from SalesForce. This would be the top level in the as-a -service family.
Going a level below, or PaaS ( Platform as a service), this can be viewed as having an operating system like Microsoft Windows server on top of which you install the CRM service for your users.
Going another level below, you have the IaaS (Infrastructure as a service) or server or virtual server provisioned using VMWare where you have to build the whole OS together with installing the application for your users.

SaaS must be built on top of good platform and infrastructure. Also, you need to make sure that applications work as you need
