I'm looking for a grounded staffing model for the TeamSite Administrator role so that we can estimate the future staff size. Our TeamSite role does the following: Support is for major projects, enhancements and production support issues. Maintenance of user profiles, creation of new branches, on-boarding of new sites, implementing upgrades and patches, management of content deployments.We are on-boarding more web properties into TeamSite and need to determine how many TeamSite Admins we need to support the efforts.We are considering factors like: Number of deployment sites, Technology of deployment sites, Web Pages, Content Users, Complexity. and Expected production incidents.Anyone have any insights in how I can come up with a predictive model?
