AI Readiness Assessment

Is Your Business Ready For AI?

According to Gartner’s 2023 Data & Analytics Leadership Vision, while 70% of organizations have invested in AI, only 19% have actually scaled those solutions enterprise-wide. That’s a cosmic chasm between ambition and tangible success! From my vantage point, 25+ years spent simplifying data environments, orchestrating cloud migrations, and bridging the gaps between on-premises and cloud tech. I can tell you that most AI projects fail to launch due to wobbly data foundations. Think of it like building a futuristic skyscraper on quicksand: even the best architectural plan can’t compensate for a weak base.

Below is a data-focused checklist to ensure your AI journey doesn’t end up like a starship fresh out of hyperfuel.
