  • Thinking Leadership 4.0

    Produced by John Grisby/Professor of Practice

    There is a practical, 'hands on' side to leadership mindset, which are models and methodology. This podcast however takes you down the other route, exploring the vast human scientific domains that influence leadership mindsets. Ultimately these domains impact how leaders and their organisations/industries think, adapt, develop, respond, perform and survive (or not).

    Down the Rabbit Hole takes an interdisciplinary approach to leadership. It integrates
    themes that cut across and connect between different disciplines, and their relationship to the real world of leadership.

  • Grey Matter Global Ltd. is a leadership strategy consultancy for business/industry4.0 -
    the fourth industrial revolution. We help leaders prepare/shift mindset from
    ‘3.0’ to ‘4.0’, to make sense of complexity, change and solve difficult problems.
