One way to make a decision with a team or a partner is to clearly make a decision. Have a budget, do the math, lay out the risks and the options and decide with intent.
The other method is to weasel your way forward.
Act as if.
Hide relevant facts or conceal your fears.
Avoid talking about the real issues, figuring that you’ll figure it all out as you go.
When you are uncomfortable with here, and it’s really tempting to want to be there, it’s easy to weasel your way forward. It feels urgent and appropriate. It rarely is.
