Functional size of real-time software: overview of field tests
S. Oligny, Alain Abran, Jean Marc Desharnais, Pam Morris · 1998
In most software cost estimation models, software size is the key cost driver. Such models use either a technical measure of software size, based on lines of code, or alternatively a functional size measure which can be known earlier in the software life cycle. However, even though Function Points is the most widely used functional size measure in the MIS domain, practitioners have often pointed out its limitations for measuring the size of real-time or embedded software; therefore, it is not currently considered as an adequate input parameter for estimating real-time software effort.
