Authors: Brandon Pfleckl, Raja Srinivasan
The Service Authority of Prince William County (SA), Virginia provides water and sewer services to a population of 360,000. The SA recently implemented an ArcGIS Server based Enterprise GIS system (EGIS) which enabled its GIS-Vision of becoming a GIS-centric organization at the forefront of GIS technology. EGIS programs can be highly beneficial to many organizations; however, getting proper approval can be a impediment to implementation. Determining a Return on Investment (ROI) can assist tremendously with buy-in from management and other decision makers and more fully justify the project. While subjective ROI analysis is relatively easy, more specific quantitative calculations can be tricky and time consuming. This paper explorers proven methodologies for developing an EGIS ROI; identifying opportunities, constructing a GIS program, specifying costs and benefits, calculating metrics and presenting your report for review and buy-in from decision makers. The paper further explorers an ROI project case-study involving the SA.
