There's no one-size-fits-all answer to this question, as the tools a product manager uses will vary depending on the specific product they're managing and the company they work for. However, there are some common tools that many product managers use, which can be broadly divided into two categories: project management tools and data analysis tools.
Project management tools help product managers keep track of their product roadmap and ensure that tasks are being completed on schedule. Common project management tools include Jira and Asana. Data analysis tools help product managers track how users are interacting with their product and identify areas for improvement. Common data analysis tools include Google Analytics and Mixpanel.
