My definition of a business application is a piece of software that:  

> Captures **inputs** to produce **outputs** that support business **outcomes**.

  
Given that definition, a business app should be designed as follows:

1. Identify the business outcomes.
2. Determine the minimum outputs needed to achieve those outcomes.
3. Determine the minimum inputs needed to provide those outputs.
4. Design a data schema for storing inputs.
5. Enforce the business rules that transform inputs to outputs.
