Three checklists before you import a new cohort dataset

data hygiene · onboarding · checklists

First, label the dataset with a steward and a refresh date on the cover page. Second, document known gaps plainly so facilitators do not accidentally treat missing columns as moral failures. Third, align on whether learners may export snippets or must keep work inside the classroom sandbox.

These checklists mirror what Korean enterprise clients ask during onboarding workshops. They reduce the awkward mid-cohort pause when someone discovers a field was deprecated.

MetricHarbor shares the checklists as part of bundle preparation, not as a hidden upsell. They are boring on purpose; operations teams need boring reliability more than novelty.

When teams skip the steps, we still run the program, but we annotate risk in writing so expectations stay honest.
