1 00:00:00,190 --> 00:00:04,000 And the answer is the third one. The traditional software phases which are the 2 00:00:04,000 --> 00:00:05,960 ones that we just discussed are requirements 3 00:00:05,960 --> 00:00:08,820 engineering, design, implementation, verification 4 00:00:08,820 --> 00:00:10,630 and validation, and maintenance.
