Requirements Specification

A Requirements Specification (german: Lastenheft) outlines the expectations and requirements of a charity for a software system ("What do we want to achieve?"). It defines the key goals, functions, and parameters of the planned solution from a business perspective. A requirements specification is often created to evaluate an online donation tool or CRM software and serves as a foundation for the pre-selection of suitable tools as well as for developing a functional specification document ("How do we implement it?").
