Pick the path that matches your next job. For CRM work, test how an enquiry is owned before moving records. For email growth, plan one subscriber journey and decide what action you will measure.
CRM: evaluate, migrate, follow up. Test a CRM against your follow-up; map and pilot a spreadsheet migration; then assign owners and stop rules.
Email and growth: signup, sequence, measure. Test one subscriber signup and journey; name campaign links consistently; then check enquiries separately from clicks.
