SAFe and Scrum are protocols for developing software. Most complex software needs to be broken into parts and handled by different programmers. Scrum is an excellent strategy for small development teams while SAFe is great for larger organizations. Finding someone who is an expert on these approaches is a real asset because that SAFe Scrum Master is capable of coaching a new team or an old one that is used to less efficient methods.
Programs depend on exacting code in order to work, and building it is like an assembly line where pieces have to go back to the start of the line more than once. Just as precisely cooperative workers can hammer a beautiful steel sword, programmers can save a lot of time and avoid many mistakes if they have an excellent framework for handling bugs and misunderstandings. Better position your workers and make better products faster.
