In this design science research, we (Eero Hosiaisluoma, Katja Penttinen, Juha Mustonen, Jukka Heikkilä) propose integrating Enterprise Architecture (EA) into an organization’s development work. We call this method Lean Enterprise Architecture Development (LEAD) – also known as Lean EA (LeanEA). See the research article from the Research Gate link. Or you can get the pdf from […]

Business Architecture Modeling With ArchiMate
Business Architecture can be modelled with small set of diagrams and subset of ArchiMate elements. Here is introduced some typical diagram types, that can be used for business layer modelling, as well as linking business layer to application layer. Most of the diagram types introduced here are variations of the Layered View diagram type. Business […]
Application Architecture Modeling With ArchiMate
Introduction Application Architecture (or Solution Architecture, SA) can be modelled with the same set of ArchiMate diagram types as other levels of architecture (Enterprise- and Domain levels). Application architecture can be modelled with a small subset of ArchiMate elements as follows: Application Component, Application Service and Application Interface. Relationships between those elements can be modelled with […]
Service-Driven Approach (SDA)
Introduction Holistic enterprise development can be supported by the Service-Driven Approach (SDA), which focuses on services (instead of projects) as primary units of value creation, design, development and operations. The SDA combines both customer oriented (“outside-in”) and organization internal behavior and structure oriented (“inside-out”) approaches. By focusing on services, enterprise development (or an IT function) can […]
