Which definition best identifies the big bang method?

• A. the big bang method
• B. the parallel method
• C. phased change
• D. remote working

Answer: (A)

The big bang method is about implementing a change across the entire system all at once, switching from the old setup to the new one in a single release. This is why the best definition is the one that literally says the method itself—doing the whole change in one go. It contrasts with the parallel method, where the old and new systems run side by side for a period, and with phased change, which rolls out the update in stages. Remote working isn’t about how a deployment is carried out, so it doesn’t describe the approach.
