Information technology. Software measurement. Functional size measurement - Reference model1. Scope Part 4 of ISO IEC 14143 defines the reference model (Figure 0. 1) to be used when verifying a Functional Size Measurement (FSM) method. The reference model consists of two components: a classification framework of Reference User Requirements (RUR) which can be sized using an FSM Method. Included are examples of such RUR as well as references to further publications of User Requirements (UR) which can be used for RUR, and guidance on selecting
