Technology and methodology use will, in my experience, inevitably degrade in an organization over the course of the technology or process lifetime. We, as project managers, need to understand this phenomena so we can get the most out of these implementation.
We should recognize that the effectiveness of techniques will fade in and fade out systematically, based upon no rational logic except this is what happens with people using tools and methods. Getting the most out of these tools at each point in their cycle will help sustain our success even as they inevitably change for better or worse over time.
The solution I’ve used most successfully for years is to simply dust off the “old” methodology, often framing it as something new or revised, and renewing the focus on doing the job the way it was intended. Most good methodologies work just fine when done with energy and understanding of what each step is intended to achieve.
