One other method
These days, we rarely work in isolation, which means we’re not responsible for every part of a task ourselves. More than likely, you’re waiting on someone else to complete something so you can do your part. When this is the case, add them to your “waiting for” list. I keep this list right next to my daily tasks. Example:
• [WF for Maytel Sumner] - Omar for the redesign shopping cart screens
• [WF for Jamison Madhok] - Rasheda for finalized copy
• [WF for Priscilla Kim] - JD for revised OKRs
This tactic, inspired by "Getting Things Done," has been a game changer. Be the highly effective product/project manager of your focus/task management and never drop the ball. Having a “waiting for” list helps me keep track of all ongoing tasks, making it easier to follow up when necessary, rather than relying solely on memory.
