Implementation Duration
The duration of a Single Sign-On implementation depends almost entirely on your IT department’s familiarity with the process and any testing and transition requirements you have.
If you have the necessary Single Sign-On infrastructure in place and you are already federating with one or more external partners, implementations can often be completed and tested in under a week.
If you have the necessary Single Sign-On infrastructure in place but you have never used the Single Sign-On feature, plan for a longer implementation as you acquire the necessary in-house knowledge to use your system for Single Sign-On. The vendor of your identity provider solution can assist you with this.
If you do not have the necessary Single Sign-On infrastructure and have no prior knowledge of the process, several months are required to implement a solution. You must purchase, test, and deploy to your production environment while acquiring the necessary in-house knowledge to use your new systems.
Using custom programming for SAML Single Sign-On instead of network infrastructure typically takes longer than using off-the-shelf network solutions. Custom programming projects are difficult to predict. Again, it depends entirely on your organization and how well your programmers understand the protocol requirements and libraries used to handle the Single Sign-On protocol details.
