What is the purpose of the MoSCoW method?

• To prioritize requirements

• To analyze survey data

• To design user interfaces

Answer explanation

Benyon (2019) talks about prioritising requirements, so if you have a long list of requirements you decide what has to absolutely be included and leave other requirements for a later version. There is a technique called the MoSCoW method that can help with this:

M - Must have  

S - Should have  

C - Could have  

W - Won't have
