Welcome to our Technical Support Page for the System-Wide Analytics and Projection (SWAP) Suite of Tools!

Our tools help communities plan and prioritize changes that will help reduce homelessness the most.

SWAP is a joint project of Focus Strategies and the National Alliance to End Homelessness. SWAP is designed to enable communities to use local data to understand what their current system is accomplishing and model what happens when system and program changes are made. The SWAP tools can be used to inform system planning and system change efforts to reduce homelessness over a period of up to five years.

The SWAP tools are free and any community is welcome to use them.  Below are links to the tools, as well as a range of technical support products and FAQs.  We welcome your comments and questions about SWAP.  If you have any feedback to share or if you are interested in technical assistance from Focus Strategies, please email us at

Guidance For Using Local Data For Performance Measurement

SWAP General Information

Welcome to SWAP – a one pager that describes the tools and what they can do for your community.

Overview of SWAP Performance Measures

Are We Ready for SWAP? –  Frequently asked questions about data needed, staff capacity, and community approach needed to use SWAP.

CoC Tasks and Time – An overview of the tasks and activities that the CoC level staff will need to undertake in order to use the SWAP, along with estimates of the time required.

HMIS Tasks and Time – An overview of the tasks and activities that the HMIS staff will need to undertake in order to use the SWAP, along with estimates of the time required. – Coming Soon.

Base Year Calculator (BYC)

The BYC assembles data from a community’s Housing Inventory Count (HIC); HMIS data; and program budget data to create a “base year” of performance data from which to begin modeling. Outputs of the BYC include a project-by-project evaluation of HMIS data quality and project level performance measures. The BYC is used to populate the System Performance Predictor (SPP) but also is a useful standalone tool that allows communities to understand the performance of their existing system. Tools and guides for using the BYC are linked below:

Sample performance outcomes by project – BYC results for Anytown:

Base Year Calculator User Guide – Provides a concise set of step by step instructions to get started with the BYC. Once you know what to do, use these templates to upload your data:

Frequently Asked Technical Questions – FAQs on using the BYC and Budget Tools.

HIC Extraction Instructions – To populate the BYC, data must be extracted from the community’s Housing Inventory Count (HIC) in the HDX system. This document provides instructions for the HIC extraction.

Budget Collection Tools

To populate the BYC, communities must collect data on the annual operating budgets of all programs included in the analysis, so that project performance can be understood in relation to level of investment. These are template tools communities can use to collect the needed data from providers in a consistent manner.

System Performance Predictor (SPP)

The SPP is an Web-based tool that uses your community or State’s BYC results and allows for project-by-project and year-by-year changes over a five-year time period. The SPP models changes to all key elements of homeless system dynamics, including population size and new entries into homelessness, investment and capacity changes, and program performance. As changes are made, users can see the impact on the overall performance of the system and on the size of the homeless population and selected subpopulations. The types of interventions that can be modelled include shifting investments to more cost-effective solutions matched to population, targeting literally homeless people while diverting others, increasing utilization rates; reducing lengths of stay, increasing exits to permanent housing and reducing returns to homelessness. Tools and guides for the SPP are linked below:
