Be abit close for my own comfort at DOH since I prefer to relax abit on connections, rather than rush. A lot of the QR board members will say it is plenty doable in business class.

If it is your first time at DOH, you can either switch to a flight with a longer layover to enjoy the lounges/shower or can keep the same itenerary and book a meet and greet through QR, who can help you navigate the airport a lot faster

Ultimately depends on your departure gate; for example, when I go to CGK, they always use the furthest possible gate; so 1 hour connections are abit tight.
