From page 133...
... After approval is obtained for deployment, ongoing monitoring evaluates effectiveness and risks in the real-world environment; drugs may be recalled if they fall below acceptable standards. Similarly, product development programs typically rely on increasingly constrained testing regimes that, prior to deployment of a new system, mimic the real-world operating environment as nearly as is possible.
From page 134...
... in traditional technology development programs. A key issue in testing information-based programs is access to data sets that adequately simulate real-world data such that algorithm efficacy can be evaluated.
From page 135...
... During this phase, the program should be field-tested -- subjected to the equivalent of human subject trials in the drug development process or operational test and evaluation (OT&E) in traditional technology development programs.
From page 136...
... For example, new technologies may become available whose adoption can make the system more usable, or new applications may be required in a new operating environment, or new capabilities previously planned but not yet incorporated may be deployed. Because system evolution results in new functionality, reapplication of the framework described in Chapter 2 is usually warranted.

This material may be derived from roughly machine-read images, and so is provided only to facilitate research.
