It is important to note that many organizations that rush adoption usually do not actually adopt the practices long-term. If you ask the developers and managers, you will find that some of the practices are being used, some superficially, but many not at all. Not using the adoption curve can slow down the deployment of new ideas. The more resistance you encounter, the longer deployment will take. It is much quicker to work with people who do not resist.
Some organizations use training companies so that more people learn the skills in parallel.
Even so, the adoption and practice of the new skill takes time. A proportion of the audience will always believe that the new idea is a total waste of time. Where to go from here. In summary, we suggest you study your organization and use the adoption curve to facilitate your process improvement program. Start with the early adopters and don't worry about the laggards for now.
