Seeking Advice to Boost Productivity

Hi, I'm a Product Manager in the payments industry. My product org is a market leader in a South Asian country—super fast-paced, launching a new product every 3 months (unlike my previous org, where the same work took 3x longer).

My background is in service-based and managed services, where my role was limited to delivering specific asks—I've excelled there and built strong domain expertise. Now, I'm handling end-to-end product build: from UX design, product construction, legal/compliance, rollout, and pricing—everything.

I'm new to in-house products (though domain-familiar), which makes drafting requirements difficult sometimes.

• I work remotely, so no close connections with team members.
• I manage 4 scrum teams and 3 PMs under me.
• The only AI tool I can use is Copilot.

I need your help and suggestions here:

• I feel I'm not productive enough. What has helped you stay more productive and resourceful? I think work in more traditional way, over thibk at times specifically while responding, drafting PRDs PRDs
• What worked for you ? What processes do you follow? What apps do you use for notes? How do you handle calls (I have 5 hours daily; I attend 3-4 hours live, with the rest as recordings or MoMs)?
