Patrick, The original poster is a well known agile voice, the Agile Alliance's 2005 Gordon Pask Award for Contributions to Agile Practice. But these single vision statement reveal a narrow understanding of how software is developed outside their own experiences. This is rhe difference between "knowing" and "doing." In our "doing" domain if Software Intensive Systems (SIS) and guidance like Estimating Software Intensive Systems http://amzn.com/0321904923 http://goo.gl/E01X2d Engineering SIS http://goo.gl/Nk0dgn In these domains, tools are a critical success factor, starting with the Systems Engineering design tool, one of the ones we use is http://www.vitechcorp.com/ and http://www.threesl.com/index.php at NASA. But the notion that complex systems and resulting complexity in the design, development, and testing can some how be tested for complexity by having the system's work be contained on a "board" (physical sticky notes on the wall), begs the question - "you ever work a program where that suggeston would be laughable?" Probably not.

To build a credible estimate for any project, in any domain, to produce a solution to any problem, we need to start with a few core ideas. Gather historical data. Unless you're inventing new physics, it is very unlikely what... Continue reading

So this is yet another example of "knowing" versus "doing" It'd be unlikely that "knowing" that plans change and acting accordingly is not the norm, behaving in that way seems to somehow be harder outside of the domains where "Program Planning and Controls" is the norm, even for agile software intensive systems https://www.nasa.gov/sites/default/files/files/Session3ConsolidatedCharts%281%29.pdf

No credible planning process "sticks to it too rigidly." The "plan" is actually the process of executing the strategy. So the "plan" is an object that is adjusted. The confusion comes when some see the "plan" as a throw away "object." It is not. The "plan" is the representation of the current strategy for success. I can look at the "plan," touch it, put it on the wall, send it to the participants, so they know what work must be done to "increase the probability of success." The "plan" is a "thing" developed from the strategy. Here's how we apply those concepts http://www.acq.osd.mil/se/docs/IMP_IMS_Guide_v9.pdf and where the capabilities that the plan describes come from www.acq.osd.mil/ttcp/reference/docs/JSA-TP-3-CBP-Paper-Final.doc That original phrase is often misused in the absence of guidance on how to plan, and how to execute from the plan. It becomes a platitude to escape answering the question "what does done look like."

Mike, Thanks for the follow as always. The notion that ideas can live in the absence of testing appears to be troubling for some. From our common experience in the physics world, we both know the feeling of standing in front of the PI (in our case a Nobel Laureate) and making a suggestion about something we know quite a bit about. Only to have him ask a simple question - "have you tested you observation and explanation of that observation against all the other possibilities that may be the cause of what you have seen?" No, please do, then come back. As experimentalist, we be asked to stop by the theorist student's office as well just to confirm we actually had the underlying principles well in hand before proceeding to confirm what we saw, which could possibly have been "statistical noise."
