The Lean Portfolio Management function that controls funding, are given sole authority to approve which Portfolio Epics move into each stream. Epics are not explanations about a problem that needs to be solved. They are pre-formed ideas about how best to solve those problems.
Right away we can see signs of the old-school mindset of viewing teams as a “delivery” function instead of a strategic one. The high level thinkers come up with ideas, and the low level doers execute on those ideas. Ignored is the possibility that those closest to the work might be best equipped to make decisions about it. Escaping from this misguided mindset is a core goal of Agile thinking that SAFe fails to remotely accomplish.
It has long been understood that striving for originality as an end in itself is the mark of an inferior artist. The personal style of a good artist is never something that has been deliberately cultivated and forced but something that has appeared unsought as inevitably as the personal style of a man's handwriting.
But since artists of note are seen to have a distinct personal style, no artist can hope to make a reputation in a competitive society unless he too can show a distinctive style which easily differentiates his work from that of other artists and draws attention to it. Therefore artists of little capability or uncertain vocation will take great care to make their work look 'different', whereas those with any certainty in them will know that their work cannot help but look different from that of other people any more than signatures can.
