Which implementation approach is associated with higher risk?

• A. Big bang
• B. Incremental
• C. Hybrid
• D. Parallel rollout

Answer: (A)

In any health information system rollout, how you switch from the old to the new system drives risk. The big bang approach makes the entire organization switch to the new system in one go. If there are defects, data mapping issues, performance problems, or user adoption hurdles, every part of the organization experiences them at once. That means downtime can be longer, workflow disruptions are widespread, patient-care processes may be suddenly affected, and rollback options are hard to execute quickly. In short, there's little opportunity to detect and fix problems before they impact daily operations, so the overall risk is high. By contrast, incremental rollout stages the implementation, testing it in chunks, which confines any issues to a smaller group and time period. Hybrid combines strategies to balance speed with safety, and parallel rollout runs the new system alongside the old one for a period, providing a safety net and a built-in workaround if problems arise. These approaches allow issue identification, targeted training, and smoother recovery, reducing risk. So the approach associated with higher risk is the big bang implementation.
