Common challenges when implementing EHS software include poor data quality, unclear workflows, too many custom forms, lack of supervisor buy-in, weak user training, resistance to change, limited mobile access, and trying to launch every module at once. U.S. high-risk employers may also struggle with remote worksites, contractor access, shift work, and inconsistent processes across locations. Safety managers can reduce these risks by starting with priority workflows, cleaning data before import, involving field users early, testing forms before launch, setting clear ownership, and measuring adoption after rollout. Simplicity is often the difference between success and frustration.
