As the picture suggests we cover popular scaling frameworks like SAFe, Scrum@Scale, LeSS, and FAST, but we also look more discretely at principles, patterns and practices because you don't need to be limited to a monolithic framework in it's entirety.
On the surface, we scale because we need more people. Perhaps we can think about the why, and the ramifications of scaling more broadly so go beyond getting bigger and get better instead.
Many organizations pick a scaling framework, purchase some tools, have a couple of days of training for the staff, and then they consider themselves as agile. Perhaps we take a more mature perspective that recognizes scaling challenges and patterns of success.
