I have created the following checklist for myself, and always keep it ready before I plan a hike or mountain hike. And before you start, check the checklist whether everything is included and has also been clarified. I can recommend such a checklist to everyone (in their own way). Important: Always pay attention to the current body shape, how someone is doing and whether he feels fit or not. Not to underestimate.

Assessment / alternatives
My planning is realistic (schedule, personal skills, equipment, etc.).
I checked requirements and weather forecasts and worked out appropriate alternatives (e.g. abbreviations) so that I could reschedule on site if necessary.
The current conditions allow this mountain hike, I have a good feeling about it.
For hikes in groups: Hiking planning and responsibility in the group is regulated. Everyone is informed and motivated.
