    McKinsey productivity and knowledge-management studies

    Where value is already real

    McKinsey's work shows strong productivity potential in knowledge workflows, especially where natural-language retrieval and task support reduce repetitive search and synthesis.

    The opportunity is largest where teams can convert internal knowledge into accessible, searchable, high-trust operational context.

    Productivity indicators frequently cited in McKinsey materials

    ~20%

    Knowledge-worker time historically spent searching/gathering info

    20-25%

    Potential improvement in interaction-worker productivity

    Up to 35%

    Potential reduction in information-search time with searchable internal records

    Up to 30%

    Reported internal time savings in a gen AI knowledge platform case

    Where hype tends to appear

    Overstatement usually comes from assuming broad enterprise transformation from narrow tool usage. Localized productivity wins do not automatically convert into system-wide P&L impact.

    Real value requires process redesign, data quality discipline, role adaptation, and governance controls.
