A Mumbai-based retailer begins an analytics project by first stating that it wants to reduce customer churn in its loyalty programme and defining what success will look like. Which stage of the data analytics lifecycle is this?
This is the business problem definition or objective-setting stage. The lifecycle starts by clarifying what question must be answered and how success is measured, before any data is collected, cleaned, modelled, deployed or visualised.

Explanation
Every analytics lifecycle begins by understanding the business problem and setting measurable objectives. Cleaning, deployment and visualisation occur only after data has been identified, collected and analysed. Stating the churn goal and success criteria is therefore the problem-definition stage.
