Gartner Top 10 Strategic Technology Trends for Smart Government
“In the belief that every agency or government program business process is unique, program managers have historically favored the development of highly customized IT solutions over commercial off-the-shelf (COTS) products or cloud-based business services. More often than not, the presumed uniqueness of a business process is overstated. Taking the time to decompose and document processes with a business process management (BPM) methodology will identify business functions where variability is low and common practices (and software applications) can be shared.”
Current Trend in GIS
New GIS technologies allow configuration as an alternative to customization.
“Application development and deployment is nolonger just for the code warriors.”
Approaches to Configuration
Model Builder
Workflows and Tasks
App Builders
Model Builder (core in ArcMap and ArcGIS Pro)
Models are:shareabledeveloped on Desktop; publishable as services
GP Tools (in both ArcMap and ArcGIS Pro; some in core and some require extensions)
Configuration Experience
Model to Calculate Tree Height from Lidar
User Experience
Model to Calculate Tree Height from Lidar
Configure Workflows & Tasks
A custom step might be replaced by a series
of simple out-of-the-box steps
For the Enterprise, workflows help ensure consistency & quality
Workflow Manager Extension
Task Assistant Manager in ArcMap (extension)Tasks in ArcGIS Pro (core)
Example Task Assistant – User and Configuration Experience
Task for Georeferencing Scanned Maps
Configuration Experience

Driving Forces
• The pace of technology change is increasing.
• Customers expect single-topic, focused, easy-to-use apps that run on any device.
Antoine de Saint-Exupery:
“A designer knows he has achieved perfection not when there is nothing left to add, but when there is nothing left to take away.”
Recommendation for the Sustainable Enterprise GIS
1) Break the processes into simpler focused apps
Use Traditional Patterns
“Configure first. Customize only when necessary. That should be your first instinct.”
“Don’t reinvent the wheel.”

Commercial off the Shelf or “COTS”
• Always deploy Commercial Off the Shelf when possible…• Customization only when business value is greater than
life-cycle cost of development• An 85%-90% solution is acceptable to avoid long-term
maintenance headaches
