Biggest Hidden Inefficiencies in GTM Motion and Data Quality Challenges

One stat from a recent GTM report jumped out at me. 58% of leaders feel execution is efficient, yet 47% point to lead and data quality as major blockers. That gap suggests efficiency may be perception-driven rather than system-driven. As AI becomes more operational, fragile data foundations get exposed fast. Curious where folks here see the biggest hidden inefficiencies in their GTM motion?
