  20. 20. We formalized our requirements and did a high level evaluation of the options See: WIBuyVSBuild.xls Build vs. Open Source vs. Buy © 2007 Board of Regents of the University of Wisconsin System Functional/Non Functional IAM Category Scope Requirement Compliance Module or Feature Effort F Authorize System Shall provide the ability to define combinations of create, retrieve (read), update (modify) and delete permissions to created appropriate system roles (e.g. "Affiliation Manager") None Authorization Manager Difficult F Authorize System The system shall support integration with the institutional and/or standards-based authentication mechanisms (e.g. pubcookie, Shibboleth, SAML).
