The Business Benefits of GIS: An ROI Approach, ESRI
Gillespie (1994) states that efficiency benefits arise when GIS is used to reduce costs of a task that, in the absence of GIS, would be handled by some other method.
The Riverside, California, Planning Board used to take up to four hours to manually produce a single map for a board meeting. They now produce an equivalent map in about half an hour using their GIS.
Typical efficiency ratios of 2:1 to 5:1
Revising spatial data:
At the City of Indianapolis, a full time draftsperson and two part time drafters were unable to keep up with base map updates that involved subdivisions. After GIS implementation, these same activities were accomplished with a half-time staff position and the base maps were kept current within a few days.
Typical efficiency ratios of 3:1 to 10:1
Locating spatial data:
Lee County, Florida frequently requires an assortment of information about land use, flood zone, watershed, zoning restrictions and variances, parcel frontage, parcel acreage, and owner verification for land development issues. GIS has reduced time requirements from hours to less than five minutes per occurrence.
Typical efficiency ratios of 5:1 to 20:1
Distributing spatial data:
Spatial data distribution on a network is instantaneous and replaces such tasks as making copies, mailing copies, replacing copies in books and files.
Typical efficiency ratios of 10:1 to 100:1
Using spatial data:
The Metropolitan Sewer District of Greater Cincinnati saved 10 to 16 workweeks in a single instance by using GIS rather than manual methods to estimate the number of customers in a particular drainage area as part of a permit renewal process.
Typical efficiency ratios of 2:1 to 8:1

According to Wyandotte County, Kansas, Surveyor Murray Rhodes, the county collected $500,000 in delinquent taxes in a single year that otherwise would not have been collected under the county’s (pre-GIS) manual system.Unpredictable Benefits of GIS
