Since the inception of HMIS, communities have elected to take a variety of approaches to implementation. An HMIS Implementation refers to the CoC(s) that have agreed to support one HMIS software and/or regularly utilize data integration to combine data from multiple HMIS software with the primary HMIS software. The three types of HMIS Implementations are:
1. Single CoC Implementation–A single CoC jurisdiction, which has not partnered with any other CoC jurisdiction around HMIS data collection, and has a single software into which the entire CoC’s data is collected.
2. Multiple CoC Implementation–A group of CoCs, often with bordering geographic boundaries that have elected to operate one HMIS for the entire region. In this case there is also a single HMIS software system, but regional partner CoCs have agreed that data from their CoC programs will be entered into one regional software system.
3. Statewide Implementation–A state that is comprised of two or more CoCs that uses one HMIS software and/or regularly utilizes data integration to combine data from multiple HMIS software with the primary HMIS software. (A state with only one CoC should code itself as a Single CoC Implementation.)
Since each HMIS Implementation is unique, no definition of HMIS Implementation types will take into account all of the local factors present in HMIS Implementations around the country. The SHP-HMIS grantee completing an APR should choose the type of implementation that best describes their HMIS.
