Three distinctive features of SAFe which I highly appreciate

Three distinctive features I highly appreciate about SAFe are:

• Dual operating model: decoupling of org structures from value streams. Honestly, in many companies it was a real cracker to start transformation promptly as the restructuring efforts of the functional hierarchy was a fragile topic. The org structure usually represented decades history of how senior managers were building the organization according to their vision, and yes some of them were also building their kingdoms, trying to shape the organization by how they thought was best for it. Thanks to the decoupling of these two aspects, it is possible to start a transformation swiftly while giving the re-structurization as much time and respect for people, their ambitions, and visions, as it needs. From my perspective the nature of these two processes: organizing around value and organizing functionally is indeed of a different nature, and the timelines are of different magnitute, and as such it deserves to be treated separately.
• Organizing into operational value streams. Designing the value streams, as described by SAFe is logical and elegant. It is an exercise I recommend to all organizations, even to those that think they have it sorted. Why? Because it will add transparency to why we organized the way we organized. I believe, to know this logic is highly important to everybody in the organization. Not only will people understand that it is an act of conscious design, but they will also respect it. Trying to design the value streams surface the choices that have to be made and the multitude of options there usually are to choose from. People quickly realize there is a degree to which the design decisions are tough as there usually are multiple equally good designs. On the other hand, the usual lack of such transparency weakens the belief that leadership knows what they do when they announce a re-org to employees, causing people to spend too much time divagating. 
• PI Planning. Planning at scale always seemed a daunting task to me. All those hundreds of people on one hand and the will to invite them all into the planning process, to make sure decisions are made where knowledge is. That has always been a challenge in my career. And here SAFe offers invaluable help for me. It offers me a template of a facilitation scheme for the PI Planning event that does exactly that. Whatever people say, I rarely see such great support.

p.s. Give any tool to bureaucrats and they will turn it into a heavy process that will make people suffer

p.p.s. Give any tool to skeptics and they will prove it does not work in our case
