My team and I have been practising mob programming daily for six months. During this time, we have grown from three individual specialists to a team of four full-stack developers and learned to overcome the myriad of challenges presented by our client's business domain.
I wrote about our adventures, learnings, and obstacles in mob programming in the Futurice blog. I'm happy to help if you need some coaching while starting mob programming.
"Likewise, in software development, the best products are not born by summing up the team's work but by multiplying their interactions. Mob programming is a lean solution to maximise the outcomes from those interactions."
