Thomas has broad experience conceptualizing
and designing large scale distributed systems, especially in the the area of investment banking and capital markets. He has been working with enterprise architecture groups reviewing application landscapes and adopting them for improved support of the corporate’s processes and value propositions.

His key areas of interest are enterprise architecture, its potential vs perceived benefits, and mechanisms for its effective implementation.

Presentation
Financial Models for Architectural Flexibility
Changing an enterprise landscape to a flexible and adoptable architecture generates cost; and building systems in a more flexible, reusable way tends to increase budgets.

In this context, an enterprise architecture function has to justify the expenditure. This not only mandates measuring its achievements; it also demands for models which value architectural options on a predictive basis.

Real Options are an approach to structure and assess architectural approaches and patterns from a financial perspective. They allow to construct a quantitative model supporting the decision making process. Traditionally, however, this model has fallen short of providing acceptable volatilities.

Infosys is using a model built on implied volatilities derived from real-world architectural decisions. We find a correlation between the technology adoption profile of companies and the volatilities attributed to flexibility.
