deployment mismatch concept

DefinitionThe failure in which the consumer that was evaluated is not the consumer that was deployed, or time moved between the two. Chapters 1 and 13. Also deployment mean, the consumer that was deployed.
ExampleThe harness read a direction the deployed consumer never sees, and its 0.909 became 0.736 in deployment.

Assumptions and scope
  • The failure in which the consumer that was evaluated is not the consumer that was deployed, or time moved between the two. A deployment score is a weighted mean over the slices actually served, so it lies between the worst slice and the best, and a benchmark drawn from the best slice overstates it unless every weighted slice matches.
  • The chapter’s case scores 0.909 on the benchmark against a target of 0.8 and 0.736 on the deployment mean, and the six bars that separate the two are preregistered.
