The document discusses three questions to challenge a company's 2020 growth strategy. Question 1 addresses whether the company is optimizing key performance indicators (KPIs) like customer lifetime value (CLV) and customer acquisition cost (CAC). Question 2 examines if the marketing team structure enables growth through specializations like performance, brand, and retention marketing. Question 3 considers how to keep the growth engine constantly running through diversifying channels, referrals, reactivations, and subscription boxes. The document aims to prompt companies to evaluate these areas of their growth strategy for the new year.
