I've been listening to The Art of Product podcast since the start and Level really didn't make sense to me as a solution even though I understood the problem.

Most issues are around context and focus when moving from an individual contributor to a lead. If a programmer I'm leading doesn't implement a feature in a way that I expect it is because the context that is in my brain hasn't been transferred to the programmer's brain. If a feature isn't being worked on then I having communicated focus and priority.

A solution would focus on revealing context and focus by:

1) Deeply integrating with Slack, JIRA, Github, etc. The tools that we already use. A new product can't be a silo.

2) Mobile or GTFO. Leads are in meetings, on airplanes, in transit, etc.
