About the Editors

Gernot Starke
Gernot Starke

Dr. Gernot Starke (INNOQ Fellow) is co-founder and longstanding user of the (open source) arc42 documentation template. For more than 20 years, he has been working as software-architect, coach and consultant, conquering the challenges of creating effective software architectures for clients from various industries.

Gernot co-founded the International Software Architecture Qualification Board (iSAQB e.V.) and the (open source) Architecture Improvement Method (

Gernot has authored several (German) books on software architecture and related topics.

Michael Mahlberg
Michael Mahlberg

Michael Mahlberg runs his own method consultancy in germany and spends most of his time supporting clients in their quest for more effective ways to work. Mostly by applying lean and agile concepts. 

Running his own computer and software related companies since he was 18, he quickly came to realize that software architecture and (develeopment) processes are in a way timeless aspects of the craft. 

In the late eighties of the 20th century he started to incorporate these aspectts into his business activities and has worked on software architecture in large scale systems for industries as diverse as media, aerospace, insurance, public sector, telco etc. 

Nowadays a lot of his work focuses on processes and human interactions – a field in wich he enganges both professionally as well as pro bono (for example he is one of the people who started and run the Limited WIP Society Cologne).    

Michaels architectural work therefore tends to be dealing with the impact(s) and implications of architectural and process decisions _on each other_ and the relative optimization strategies.

Matthias Bohlen
Matthias Bohlen

Matthias Bohlen is a coach and trainer for software engineering, as well as software architect, IT consultant and expert for Lean/Kanban.

Matthias Bohlen has a unique way of explaining complicated things clearly and making them implementable in small steps. In his iSAQB-accredited courses, he mainly teaches domain-driven design (DDD), architecture documentation (ADOK) and architecture evaluation (AWERT).

Since 2001, he has been advising software development teams who want to release high-quality, reliable software on a regular basis without having to make a heroic effort. With software architectures that are better and easier to maintain, strategically designed teams can progress more courageously and effectively in the development. Domain-driven design provides an excellent foundation for architecture, work breakdown and team setup.

Matthias Bohlen has been a member of the International Software Architecture Qualification Board (iSAQB) since 2012 and is committed to qualification of software architects there. In addition, he regularly speaks at conferences and writes for specialist journals. He was a member of the editorial team of OBJEKTspektrum.

Electronic Frontier Foundation

Defending your civil liberties in a digital world.

Based in San Francisco, EFF is a donor-supported membership organization working to protect fundamental rights regardless of technology.

From the Internet to the iPod, technologies are transforming our society and empowering us as speakers, citizens, creators, and consumers. When our freedoms in the networked world come under attack, the Electronic Frontier Foundation (EFF) is the first line of defense. EFF broke new ground when it was founded in 1990—well before the Internet was on most people's radar—and continues to confront cutting-edge issues defending free speech, privacy, innovation, and consumer rights today. From the beginning, EFF has championed the public interest in every critical battle affecting digital rights.
