I disagree, you're not including mental fatigue. I can say something like "I have a server OS upgrade that needs to be done by X date. The server uses XYZ technologies. Here is the list of stakeholders and their roles. Design me an assessment and implementation plan and outline the key milestones and their dates." Could I think through that myself? Yes but it may take a couple hours. I just got 85% of the planning work done in 2 minutes.

I feel like I'm talking with people who would rather ride a horse and buggy down a rutted dirt road for 2 hours both ways, checking the wooden wheels for damage. Giving the horses rest stops.

I think I'll take a 10 minute car drive to costco, thank you very much.
