DMIS - Diversion Management Information System — Team Lead
The Homeless Management Information System (HMIS) is a project that seeks to provide homeless individuals with the resources they need. Before admission to the program, applicants must provide evidence of their homeless status. This is followed by an extensive process of resource allocation to ensure that resources are distributed equitably and in a timely manner. HMIS aims to reduce the complexity of the resource allocation process for homeless individuals, giving them access to the resources they need in a non-discriminatory manner. Additionally, the project seeks to improve the accuracy of data and analysis related to homeless individuals and the services they receive. Finally, HMIS strives to reduce the amount of time between application and receiving the necessary resources.
