Generative AI promises significant organizational transformation through natural language outputs, but its success hinges on a robust data strategy aligned with business priorities. A solid generative AI data strategy requires high-quality, transparent, governable data and must be crafted to align with specific business goals. This involves selecting appropriate tools and technologies, embedding AI into existing workflows to enhance functionality without causing tool sprawl, and bridging the gap between technology and business outcomes by making IT a strategic function. Additionally, measuring the business value of AI initiatives is crucial, requiring continuous monitoring, defined success KPIs, and ensuring scalability, sustainability, and ethical considerations. Real business impact, such as improved productivity and new revenue opportunities, can be achieved through strategic implementation of generative AI, exemplified by case studies like Elastic's internal AI assistant, ElasticGPT.
