MA.8:0 - Use this when

Use this pattern when a current unit margin hides acquisition, later service, retention, returns or other consequential flows. Begin with the customer cohort or product use and the decision the account must support.

The pattern governs a time-related customer or product account. It returns observed and conditional resource and monetary flows over a stated horizon, with the assumptions needed to interpret acquisition, continuation and scale.

Use an adequate existing account directly. A lifetime valuation or financing decision uses the additional method required by the relevant financial practice.
