Working with data

I’m having a hard time consuming data, and would love to learn from the wisdom of the community. I work with a BA that is working with multiple teams, which means that every time i need pieces of data to complete the picture of usage i’m building in my head, I need to ask him for help and wait usually few days for a response. Luckily for me, I work in a company that’s open for new ideas and for changes. I would love to hear about different approaches that your companies are taking, and what’s the structure of the team (and the company) that enables that.
