“However, if you’re on the edge of delivery work or even further away in the organisation, you may just think that agile is a bit different to what’s gone before. You may not be close enough to delivery to experience just how radically different agile is.
This is important, because, if you think agile is not radically different to what’s gone before, you might believe that the processes and ways-of-working used in the enabling functions around delivery, that have evolved to enable non-agile delivery approaches, do not need to be changed to enable agile delivery.”

I see this all the time. People not directly working in delivery teams appreciate that agile is different, but don't realise quite how different. This leads them to underestimate the need for other parts of the organisation to change as well, and results in tams with incompatible working practices constantly butting heads. Not fun.
