Nowadays, powerful software products are used in the business environment for various purposes. Enterprise applications dominate this field. When designing a new software architecture, there is a risk that important architectural criteria may be overlooked by software architects. This is due to the high number of criteria that need to be considered. Additionally, their existence depends on many different factors that are not necessarily directly visible. Unrecognized criteria can lead to incomplete technical concepts in a project, which can then result in incorrect time and budget estimates due to the high additional effort required for the necessary onboarding. This can jeopardize the project goals. This book presents a procedural model that allows for the early identification and localization of the mentioned architectural criteria within the software architecture. It involves a systematic approach that can be applied during the development of an application. The book is aimed at software architects, IT project managers, testers, and all companies.
