business architecture

Chris Clemens

Chris leads our business architecture practice. He has spent many years working with organization’s helping them to align their strategic goals with their business model and determining the capabilities required to achieve their goals. His business architecture work ensures products and projects deliver on their promised ROI, that key initiatives are always well aligned with the changing business goals and that teams and their efforts stay connected to the “core” business. 

The approach to business architecture begins with a solid model of the business goals, business capabilities and the investments being made.  We help all levels of an organization form a unified and complete picture of the business and provide critical analysis and tools to measure how well products and projects are aligned to that business model.  We lay out where resources should be placed to maximize investments that drive business growth and strengthen operational infrastructure.  And we do this, not with a heavy handed deployment of ‘consultants’, but with a team of professionals that work shoulder-to-shoulder at all levels of an organization to develop a complete picture of the business.
