Which one of the following statements, related to the requirements phase in Software Engineering, is incorrect ?
“Modelling-oriented approach” is one of the methods for specifying the functional specifications.
The requirements phase includes elicitation, analysis, specification and validation, so requirement validation is a genuine activity.
Prototyping is a standard analysis method, and function points are the most widely used size metric derived from requirements.
Functional specifications are written using specification techniques such as use cases, structured English or formal specification; 'modelling-oriented approach' is not a recognised method for specifying them.
Hence, “Modelling-oriented approach” is one of the methods for specifying the functional specifications.
To compute function points (FP), the following relationship is used
FP = Count – total × (0.65 + 0.01 × Σ(Fi)) where Fi (i = 1 to n) are value adjustment factors (VAF) based on n questions. The value of n is
In CRC based design, a CRC Team consists of :
(a) one or two users representatives
(b) several programmers
(c) project co-ordinators
(d) one or two system analysts

Consider a project with the following functional units :
Number of user inputs = 50
Number of user outputs = 40
Number of user enquiries = 35
Number of user files = 06
Number of external interfaces = 04
Assuming all complexity adjustment factors and weighing factors as average, the function points for the project will be
In function point analysis, the number of complexity adjustment factors is
