How to highlight to my managers manager that my manager provides no value to the business?

Hey all,

I’m in a tricky situation and looking for advice. My direct manager is a great guy on a personal level - friendly, easy to talk to and well liked. However, provides little to no value to the business (through his own admission) and offers no real support to our team. They don’t help with development, problem-solving, or even basic leadership—it's like they’re just… there.

He often says to me "I'm not sure what I am supposed to be doing here, I don't know what my role is and I don't know what they want me to do"

On top of that, they don’t seem to understand the basic requirements needed to perform the tasks they assign. This leads to unrealistic expectations, poor decision-making, and confusion among the team. We often have to figure things out ourselves because our manager simply doesn’t have the knowledge or skills to support us properly.

The team is constantly picking up the slack, and it’s frustrating to see inefficiencies go unnoticed. I want to raise this with their manager, but I need to do it in a way that’s professional, objective, and won’t backfire on me. Has anyone been in a similar situation? How did you approach it?

Any advice on the best way to highlight this issue without it looking like personal criticism? Would appreciate any insights!

Thanks!
