GeoConnections geospatial return on investment case study: PRISM-GIS and PRISM-911
Notice bibliographique
Résumé
In late 2009 GeoConnections commissioned a Geospatial Return on Investment Case Study to add to the body of knowledge of case studies based on the GITA ROI methodology for financial analysis of geospatial projects. The study focuses on the PRISM-GIS and PRISM-911 applications developed by the City of Quinte West in Southern Ontario. PRISM-GIS, launched in 2007, assists First Responders during emergency situations in the field and at the Central Command Centre and facilitates communication between the field and the Command Centre. PRISM-911, launched in 2008, provides emergency notification by telephone. Backward-looking five-year analysis of Quinte West PRISM: Total investment has been $130,757 (2006 $CA). Cumulative benefits are $405,972 (2006 $CA). Net Present Value is $275,215 (2006 $CA), with an annualized Return on Investment of 42.1%. Breakeven point was reached in 2008, two years into the project. The greatest tangible benefit is lowered risk to public health. Considerable benefits were also found from efficiencies in transferring manual notification to automated notification. Forward-looking 15-year analysis of Quinte West PRISM: Cumulative benefits are $3.5M. Net Present Value is $3.1M with an annualized Return on Investment of 54.33%. Payback period is under one year as a result of startup costs being externalized into the backward-looking study. This high rate of return and short payback period reflects the dramatic benefits realized through leveraging the initial work done by the City of Quinte West. Sensitivity analysis: A combined 19-year analysis of Quinte West PRISM showed Net Present Value of $3.109M. ROI is 31.66%. Sensitivity analysis was also performed on the combined 19-year business case showing only benefits to the City of Quinte West, by removing public benefits. Net Present Value to the city alone is $1.261M, with an ROI of 12.84%. Huron County is Quinte West's first external client for PRISM. Huron recently leased PRISM from the City of Quinte West, launching it in November 2009. Forward-looking 16-year analysis of Huron County PRISM: Cumulative benefits are $4,154,920 with a Net Present Value of $3,503,431 and an annualized Return on Investment of 33.61%. Payback period is one year. Huron County's Net Present Value is approximately $400,000 higher than the Quinte West combined study NPV, predominantly a result of greater public benefits from automated notification of Boil Water Advisories. A province-wide analysis illustrates potential costs and benefits if 50 municipalities, counties or regions adopt the system. Cumulative benefits are $163M over the 15-year analysis. Net Present Value is $132M with an annualized Return on Investment of 28.52%. Payback period is one year. Sensitivity analysis was performed to show the effect of slow ramp-up of 50 agency implementations of PRISM over the lifetime of the analysis. This forward-looking 15-year analysis showed Net Present Value of $79.3M. ROI for the ramped study is 26.03%. Cumulative benefits for the ramped study are $100M.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
