“…In order to get good long term molecular film growth rates, long term measurements were made, but without changing the wafers. The result here was startling, the thickness of molecular layers did not evolve linearly and instead reached an equilibrium value 5 , 6 . This equilibrium thickness is much smaller than is conventionally predicted.…”

“…We will represent the ultimate development of the model before its launch as the Ω (last) revision and it is depicted in Eq. (6). In this example, the number of performance metrics has increased, as has the number of system parameters.…”

We formulate the lessons Northrop Grumman personnel have learned from their work on development of the James Webb Space Telescope. These lessons are strategic in nature and bear on the common behavior during development of all large complex systems, such as astrophysics missions, also known colloquially as Flagships. To justify the expense, a Flagship must be a large leap in scientific capability, demanding new architectures and technologies coupled with an intolerance to risk. We define "The Problem of Newness" based on our experience and data from Webb's development. This unseen hand was present during Webb, and it is only in retrospect that we have been able to define it and present it as a lesson for the future. Future missions, Flagships in particular, should recognize the challenge of newness as a natural consequence of development and take steps to minimize its impact.
