The most successful “transformations” or running of agile projects I’ve seen have been because key people understand the value in iteration. And they organise the entire operation around being able to iterate on the product.
I’ve seen organisations do all the rituals, hold all the meetings, do certification courses but they still don’t wrap their heads around the idea of creating shippable product iterations at least once a month. They just end up dividing the work they were already going to do into arbitrary 2 week “sprints” and wonder why they’re not being efffective.
