We are exploring the idea of consolidating analytics and reporting silos within our organization. Since we're in the "infancy" of analytics and are a smaller organization, we feel we need to consolidate before deploying self-service options. If willing to share, I would love to hear how other companies have done, or do this currently, and what the experience has been like. We would be starting with small groups and building them out strategically as needed. Anything unexpected come up or things you wish had been considered ahead of time? Or perhaps something that was a huge success? We are an Alteryx shop so at least we have a good start there! 
Feel free to message me at kara.mills@idq.com or reply on the board. I'd love to get a best practices discussion going!
