During Round 1, you go through steps 1-5. Then Round 2 begins and it again involves a diagnosis including the learnings from Round 1, what worked and what didn't, what needs more focus, what's done it's job etc. and assess what objectives you'll keep from Round 1 and whether you'll introduce anything the next next round. For marketing, replace round with your operating cycle (quarter, year, etc).
Check out this animated video explaining the concept.
