We've had to ask you this sort of thing more than once before. This kind of thing is not ok on HN, regardless of how wrong someone is or you feel they are. Please make your substantive points thoughtfully and respectfully.
I will state this plainly. It’s laziness. He knows how to use Jira and doesn’t want to spend time learning a new tool. There is no risk involved with these anymore. It’s not a risk, it’s effort.
Using Jira is a form of organizational debt. He didn’t want to put in the work up front to set up something better because he knew Jira already, which is fine. But everyone on the engineering team pays the price every day now because Jira is awful. You have to decide, is it worth spending 10 hours on the weekend learning Linear or do I make my whole organization suffer? He chose the former. But it’s not a risk mitigation thing. It’s a time trade-off thing.
So PM is supposed to be three things in one - planning, monitoring and adjusting. Now "true (scotsman) leadership" constantly keeps adjusting plans to meet changes in the environment.
But usually this is too complex
In addition do not co-ordinate future development. that's not like military planning - soldiers do not say "we are going to invent a new rifle then be at the rooftop at 6pm ready to fire it"
only co-ordinate with what you have
