To answer this question, let's go through each statement and determine if it is true or false for informal reviews:
I. Easy to get started and have some benefit - This statement is true. Informal reviews are generally easier to initiate compared to formal reviews, and they can provide some benefits even without following a strict formal process.
II. Have no or minimal formal process - This statement is true. Informal reviews do not have a structured or formalized process like formal reviews. They are typically more flexible and less rigid in their approach.
III. The process must be documented - This statement is false. Informal reviews do not require a formal documentation process. They are often more casual and less structured, allowing for a more flexible and informal exchange of ideas.
IV. May include "paired programming" - This statement is true. Informal reviews can include activities like paired programming, where two individuals work together to review and improve code or other artifacts.
Based on the above analysis, the correct statements for informal reviews are:
A. I, II, and IV
Therefore, the correct answer is A.
