Consider that business managers currently spend 54% of an average work day on administrative chores such as scheduling, budgets and reports, according to an Accenture survey in the Harvard Business Review. They spend just 10% on strategic planning and even less, 7%, engaging one-on-one with their direct reports--two tasks that are key to managerial success. A growing number of AI applications, however, promise to drastically reduce business leaders' workloads by taking over many of those low-value and repetitive tasks. By 2021, this shift will generate an estimated $2.9 billion in business value and save 6.2 billion hours of worker productivity, according to Gartner. The upshot: Managers will have more time to perform more valuable work.
