Jesper has worked as an Agile and Lean coach for more than 5 years and is now in charge of the ”Agile Excellence” department at Trifork. He has a Masters degree from Aalborg University in the area of Information Systems and wrote his thesis on how to successfully manage distributed software teams.
 
Jesper helps organizations adopt Agile and Lean principles with a strong focus on understanding “why”. He has a reputation for being honest and straight forward, and has a firm belief that change management is much more about people than process. Jesper has a strong passion for Lean Product Development and continuously emphasizes that one must look at the entire software delivery system to guide success. He believes that trust is best established through transparency in the entire organization and that most problems are about communication.
 
Context Based Strategically Aligned Agility have been keywords for Jesper’s work lately. It is his experience that to create lasting change, organizations cannot rely on Best Practice rule sets, but must put effort into  understanding “why” and aligning Agile principles with the overall business strategy. Otherwise they will quickly revert to former practices when faced with difficulty and restrict themselves from great improvement opportunities.
 
Jesper regularly speaks at Agile and Lean conferences. He is member of the GOTO Program Advisory Board and has served as trackhost on numerous GOTO and QCon conferences
