Someone can be competent at a task, and “available” (they have set aside the time, or say that they have) but fundamentally need reminding/chivvying/remotivating etc. And if you can’t or won’t do those things, then the person is not “reliable”.
All of these are shifting definitions, and someone who is at one time all three may not be at a later date. Life happens, shit happens. But someone who respects themselves and the tasks that they have combined with others to undertake, will flag the changes…
