The method

Revisit workflow decomposition

Old intermediate steps may now lose information or restrict capability.

When to use it

  • A model upgrade or accumulated rules and preprocessing.

Ask yourself

  • After a model upgrade, do we still need the old workflow?

Put it into action

  • Compare keeping, merging, and removing steps on the same evaluation set. Preserve a recoverable version and track new as well as reduced failures.

Keep these limits in mind

  • Removing steps can introduce errors. Greater capability does not justify dropping necessary controls.
