Lean Architecture Toolkit Express

Describe your minimum viable architecture

The Lean Enterprise Architecture Toolkit is comprised of 15 methods or work products to describe the target architecture of your solution. Seven work products describe the business domain, while the other eight work products describe the technical domain.

Work products from the business domain are used to communicate with stakeholders from the business departments as well as business executives and business management. Work products from the technical domain are predominantly used to communicate with stakeholders from IT.

While all work products have their purpose and value, some of the work products can be optional when describing a “Minimum Viable Architecture”, for example.

This guided path shows you in what order to complete this minimum set of work products.
