Agree what growth means
Define the relevant commercial outcome: a qualified enquiry, first purchase, repeat customer or another business-specific action. Agree the baseline and the limits of the available data.
Connect the customer journey
Consider campaign reporting, website behaviour and CRM or lifecycle data together. Scope access, consent and implementation before connecting systems.
Make the next action clear
Use a shared review to decide what to continue, change or test. Report platform metrics as platform metrics and distinguish attribution models from evidence of incremental impact.
