CASE STUDY VISUALIZATION Visualization has long been con- sidered a prime tool for data analysis. But as data sets grow bigger and deeper and data management challenges mount, the need to make complex information more accessible is becoming paramount for government decision makers. However, while current technologies such as Hadoop provide increasingly better ways to store and process data, methods for quickly turning that data into meaningful visual presentations have lagged. Tableau Software’s interactive data visualization products offer an example of the next generation of tools that will allow just about anyone, across a broad range of skill levels, to produce those visualizations. Tableau also takes that further by allowing near-real-time “what if” modeling and letting users share their analyses in a collaborative environment. THE BOSTON PILOT The City of Boston, for example, is using Tableau in a pilot program in the may- or’s office to set up dashboards for vari- ous departments in the city. If it works as envisioned, the mayor will be able to walk into a control center that contains screens showing the dashboards and not only get an idea of what’s happening in those departments at any given time, but also ask questions about particular indicators on the dashboards and get answers while standing in front of the screens. The Department of Interior now uses Tableau to improve its financial analysis, and specifically to find where it is spend- ing its money and root out any discrep- ancies. The department also has a score- card that includes “aging reports” that show transactions and payments over a period of time, according to Doug Glenn, deputy chief financial officer and direc- tor of the DOI’s Office of Financial Man- agement, who added that Tableau helps to raise red flags about transactions that are getting old, “and can tell the who, when and why of those transactions.” “For example, we had an accounts re- ceivable problem where we saw the bal- ance over a 180 day period was going up and we didn’t know why,” he said. “ When we dived into it with Tableau we quickly saw the problem was with Fish and Wild- Tableau’s intelligence tools enable “what if” data visualizations and allow users to share analytics in a collaborative environment Real-time data modeling on your dashboard BY BRIAN ROBINSON GCN JANUARY 2015 • GCN.COM 31 “The days of communicating with static spreadsheets or printed statements in reports are over.” – DOUG GLENN, DEPUTY CHIEF FINANCIAL OFFICER AND DIRECTOR OF THE DOI’S OFFICE OF FINANCIAL MANAGEMENT 0115gcn_031-032.indd 31 1/12/15 3:11 PM
