Forrester recently surveyed 42 clients that are using third-party systems integration support for rollout of software-as-a-service (SaaS) solutions such as salesforce.com, Workday, and Google Apps. This data reveals that salesforce.com represents the lion's share of today's implementation support requirements. The data also shows that despite SaaS' reputation for being simple, SaaS solutions are not necessarily quick, point-and-click installs; many large-scale global projects took more than one year, and some even required more than 50 resources.
