Operations should own the strategy, with heavy tactical backup from IT and HR. IT acts as the essential technical enabler, ensuring software configurations, integrations, and data permissions are perfectly secure. HR acts as the change management facilitator, drafting corporate communications and tracking overall employee sentiment. However, Operations must steer the ship because they are directly accountable for business revenue and daily efficiency. A user adoption strategy only succeeds when it is driven by the managers who intimately understand the frontline process pain points and live in the daily workflows every single day.
