The document discusses challenges with delivering identity and access management (IAM) solutions at scale over time. It describes the organization's journey from initial proofs of concepts with SAML in 2008 to gradually establishing SAML, OAuth, and OpenID Connect as operationalized solutions by 2015. As more applications were integrated, the need to improve the speed and automation of solutions delivery became clear. Lessons learned include realizing that standardization has limits and that automation is still limited for legacy systems. The organization continues working to refine its approach to delivering IAM solutions to many applications.
