The IDEAL Model

Initiating, Diagnosing, Establishing, Acting & Learning
The IDEAL model is an organizational improvement model that serves as a roadmap for initiating, planning, and implementing improvement actions. The IDEAL model is named for the five phases it describes: initiating, diagnosing, establishing, acting, and learning.
The IDEAL model forms an infrastructure to guide organizations in planning and implementing an effective software process improvement program, and is the founding strategy employed in delivering many Software Engineering Institute (SEI) services. Organizations that follow the IDEAL approach to software process improvement (SPI) can effectively integrate SEI technologies, courses, workshops, and services into a comprehensive method for managing and improving their overall capacity.

INTRo Builds From IDEAL
IDEAL offers a high-level approach to software process improvement (SPI). IDEAL-Based New Technology Rollout (INTRo) takes advantage of the lessons learned from using IDEAL in SPI, and extends and applies those lessons to the domain of information technology (IT) package selection and deployment. INTRo goes further than IDEAL by providing a greater level of detail, content, and support for users.
