Growth curves have a predictable lifeline. This is the case for any person, team, or business. A common paradox in life and business is that the optimal time to interrupt a growth curve is before it reaches its peak. This is difficult because we find it counterintuitive to change something when it seems to be working perfectly fine.
Learning and change agility go hand in hand. Successful people and organisations know how to learn. And they learn how to change. Their growth depends on both.
Sigmoid specialises in tools and frameworks that build learning, change and resilience as core capabilities for growth. Through our coaching and leadership programs, we reinforce the strong correlation between a learning mindset and sustainable growth.
MANAGING DIRECTOR
Harold Hillman is the Managing Director of Sigmoid Curve Consulting Group, a company he launched in December 2006. Sigmoid specialises in tools and frameworks that help executive teams lead their organisations through major change with a collective sense of ownership and commitment to strong results. Since change really is the only constant in business, developing the capability to lead it, rather than be led by it, is the true hallmark of successful and enduring organisations.
Over the past two decades, as both a senior executive and external coach, Hillman has coached a number of prominent chief executives and their teams in the US, Australia, New Zealand and Singapore. Hillman's client organisations include Kraft Foods, Fonterra, Genesis Energy, Sealord, Refining NZ, Bank of New Zealand, National Australia Bank, TVNZ, Auckland Council, Foodstuffs, RD1, Air New Zealand, New Plymouth District Council, Southern Cross Healthcare, University of Melbourne, Duke University (USA), and FMG.
Hillman’s career highlights include:
• Assistant Professor and Director, Leadership Programs at the US Air Force Academy, Colorado
• Dean and General Manager, Amoco Marketing University, Amoco Corporation, Chicago
• Vice President, Executive Development, Prudential Financial, New York
• Corporate Vice President & Chief Learning Officer, Prudential Financial, New York
• Global HR Director [interim] and Director, Talent & OD, Fonterra Co-operative Group, Auckland
Hillman earned a Master’s Degree in Education from Harvard University and a Ph.D. in Clinical Psychology from the University of Pittsburgh (USA). With a strong belief that the best leaders are also the most skilled learners, Hillman coaches business leaders and executive teams to explore what is really required to drive deeper levels of engagement.
Hillman is frequently invited to deliver keynote speeches and presentations at conferences in the arena of leadership, talent and human capital. His first book, The Impostor Syndrome, was named Whitcoulls Business Book of the Year 2013. Hillman’s second book, Fitting In, Standing Out, was published in August 2015. The Six Elements of Effective Listening was Hillman’s third book, published in 2016 as an e-book through Smashwords.
