The air force is currently engaged in a peace-keeping mission in another country and has come under unexpected threats. The development life cycle is the V model. The software house needs to change their test management process to ensure delivery at the right time and quality. The software changes are coming in as the aircrew request them, as a result of their engagements with hostile forces. The aircrew have requested that the changes are made as quickly as possible.
