A tablet-based toolkit for collecting, managing, and analyzing data about the usage of physical spaces.
Suma is an open-source mobile web-based assessment toolkit for collecting and analyzing observational data about the usage of physical spaces and services. Suma’s goals include streamlining existing data collection, enabling fast, hassle-free mobile data collection, providing sophisticated data analysis and visualization capabilities for non-technical users, and promoting observational data analysis as an integral part of service and space design and day-to-day planning. Conceptually, Suma attempts to apply the longstanding user research benefits of web analytics to physical spaces and services.
Suma has proven to be far more efficient for staff than previous methods for data collection. The Suma team has found that a standardized data structure is invaluable to our ability to build analysis tools for non-technical users that can be used across the board for a wide variety of data collection initiatives. Suma is also used extensively to assess the usage of our large, new James B. Hunt, Jr. library in order to conduct a post-occupancy assessment of new services and spaces, with a particular emphasis on newer service models such as roaming reference. Suma is used by several dozen staff at our organization, and there are at over a dozen other implementations at other large academic libraries.
Examples of the current uses for this toolkit include the collection and analysis of data relating to:
- Building headcounts
- Service desk transactions
- Roaming reference services
- Experimental technology usage
- Media production activities
- Experimental space usage
The Suma application stack comprises three major components: data collection tools, a data management server, and a data reporting and analysis framework. The mobile data collection application -- as well as the data management server -- have been shown to be highly stable and the reporting and analysis framework includes a rapidly expanding set of sophisticated and highly interactive reporting and visualization tools. These include an interactive dashboard (utilizing D3.js) that presents multiple dimensions of the data using zoomable time series charts, activity and location bar charts, data tables, as well as image and CSV (Excel) exports. Comparative and experimental charts are currently under development, including a calendar heat map and charts for comparing data across multiple collection initiatives. The Suma server provides a powerful API that enables the development of a huge range of custom data analysis tools.
