The client is a nonprofit defense research organization that serves government entities, public agencies, and private subcontractors across operations research, scientific testing, modeling and simulation, program management, systems engineering, and training services. Every proposal it pursues needs its own self-contained collaboration site, and SharePoint Online did not support creating those sites automatically through custom workflows or Microsoft Flow, so IT had to stand up each new environment by hand. i3solutions built a modular proposal site creation system on SharePoint Online and handled the custom application development around it: forms built with Angular, jQuery, and JavaScript that validate what a user enters and pull related data from other lists. Provisioning that used to wait on IT now runs as process automation, with jQuery and JavaScript making REST API calls to SharePoint Online to create each site from a predefined template, customize its security groups, assign users to the appropriate roles, and apply unique permissions through a JSON definition. Sites arrive minimally configured, with a calendar already populated from the proposal milestones, and the code library behind the system is reusable on later projects. End users create their own secure sites, and only authorized personnel can reach the proposal information inside them.
