Final answer:
A new software development method or technique or testing procedure necessitates training for every member of the group.
Step-by-step explanation:
The statement that a new software development method or technique or testing procedure necessitates training for every member of the group is true.
Training is necessary because new software development methods, techniques, and testing procedures may introduce new tools, languages, frameworks, or processes that the group members need to learn and understand. Training ensures that everyone is on the same page and has the necessary knowledge and skills to effectively use the new software development method or technique or testing procedure.
