What marketing strategies have you adopted to sell the value of data and analytics to the rest of your organization?

Some strategies include: 1) Developing a compelling value proposition highlighting the benefits of data and analytics, 2) Showcasing real-world use cases and success stories to demonstrate the value,  3) Quantifying the ROI and showcase the financial benefits of data-driven decision-making, and 4) Offer a proof of concept to demonstrate the potential value within the organization.

I have recently completed a PoC for 2 different tools & showed demo to the users. Out of 2, one was selected. They liked it. But, the real challenge begins now as it is a cultural change. Many of them would be thinking about the relevance of their jobs after Analytics is implemented. It is going to be tough way forward. There are a few steps I'm taking like training them, telling them it will be good for their own careers, some success case studies & the benefit they derived from it.

Proof of concepts and case studies have really helped as the value is realised right away
