Liz Wiseman
Most organisations have more capability than they use. The people sitting in meetings are smart, experienced, and willing, yet leaders consistently extract a fraction of what their teams could contribute. The cost is invisible until a competitor moves faster with weaker talent.
Why organisations work with Liz Wiseman
She runs two distinct, primary-research-backed frameworks, Multipliers and Impact Players, that name behaviours leaders can change on Monday morning, not abstractions they have to translate.
Her Accidental Diminisher diagnostic gives senior leaders a mirror most are not expecting: the well-intentioned habits, rescuing, idea-spraying, pacesetting, that quietly shrink their teams.
The Impact Players research, drawn from 170 executives across ten countries, isolates the behaviours of the contributors managers actually depend on, which CHROs use to recalibrate performance criteria and promotion decisions.
Seventeen years inside Oracle, including VP of Oracle University, mean she frames leadership in operating terms a senior corporate audience recognises immediately.
Named the top-ranked leadership thinker by Thinkers50 in 2019 and recipient of the Thinkers50 Talent Award in 2023, with continued presence on the ranking.

Biography
The leader who is the smartest person in the room is often the reason no one else in the room is contributing. Liz Wiseman’s research into what she calls Multipliers and Diminishers, published in Multipliers: How the Best Leaders Make Everyone Smarter, isolates the specific habits that determine which one a manager becomes, often without realising. The Accidental Diminisher diagnostic that accompanies the work is now used by leadership teams across global corporations.
Before The Wiseman Group, she spent seventeen years inside Oracle, latterly as Vice President of Oracle University and global head of Human Resource Development. That operating background runs through the work. Her frameworks are written for executives who have to act on them, not academics describing them.
Impact Players, drawn from interviews with 170 executives across ten countries and surveys of 350 managers, asks a different question: what distinguishes the individual contributors that senior leaders actually rely on in high-stakes moments? The findings reshape how CHROs think about promotion, performance criteria, and the behaviours organisations should be selecting for.
She was named the top-ranked leadership thinker on the Thinkers50 list in 2019 and received the Thinkers50 Talent Award in 2023. She contributes to Harvard Business Review and Fortune, and lectures at Brigham Young University and Stanford. Her client roster, Apple, Disney, Google, Microsoft, Nike, Salesforce, Tesla, reflects an unusual fact: organisations with deep internal leadership capability still bring her in.
