Application Development Decision Framework (ADDF)

The role of information technology in Texas state agencies continues to grow, driven by digital government and constituent’s expectations.

Business Applications are where “the rubber meets the road”: they directly support business capabilities that deliver the agency’s mission. Many agencies use application development approaches that served them well in the past, but are no longer sufficient to meet the increasing demand for agility, speed to market and quality.

This Application Development Decision Framework (ADDF) will guide Texas agencies to develop its next-generation applications.

In response to DIR’s Legacy Systems Study, the 84th Texas Legislature (2015) passed House Bill 1890, which charged DIR with developing a strategy to guide the state in legacy system modernization efforts. The strategy includes establishing a statewide application development framework.

ADDF topics


The ADDF scope ranges from business alignment to process improvement, and development styles to application architecture innovation. Each topic area is comprised of individual topics, with actionable recommendations to elevate agencies' current approaches to application development.

Please download the Texas ADDF Pamphlet for publication or sharing within your organization.
