Yuval Yeret from Agile Sparks really liked a picture I made for the Sandvik's case study "Igniting Change in 20 teams within 6 months". The picture demonstrates the power of visualization and is the results of discussions with Johan Nordin from Sandvik. When he showed it to his colleagues they really got inspired and decided to make a T-shirt out of it! I'll keep you posted!
Credits to Katarina Kvist, also of Sandvik, for the colors.
