Zoe Nolan, International Events Director | Chief Strategy Officer Summit

“As a summit organiser it's always nice when a speaker receives positive feedback from the audience. This was the case when Mark presented at the Chief Strategy Officer Summit in New York last December. His session entitled 'Why Strategies Fail?' was really interactive, he even did a short quiz! I would recommend Mark as a speaker as he keeps the audience engaged and had some thought provoking ideas throughout his session.”

Cyrille Michel, Senior Vice President | Blount, Inc.

“Mark Chussil conducted a workshop on the strategic planning process at our company in April 2010. The workshop was designed to get participants to realize inherent human biases that have a deep impact on the outcome of strategic planning. Mark used numerous examples and engaged the participants in role-playing. Feedback from my team members was excellent. I recommend Mark’s workshop to anyone interested in improving a strategic planning process.”

Prof. Nancy Kymn Harvin, Assistant Professor | MBA program at Empire State College (The State University of New York)

“Mark Chussil challenges conventional wisdom, turns the status quo on its head, provokes the best ‘what if’ thinking, and makes sense out of nonsense! Engaging with Mark is evidence of one’s wisdom and commitment to winning.”

Marc DiPaolo, Policy Advisor at Office of the Secretary of Defense (USA) |

“Mark’s webinar was fantastic. The most interesting part (to me) was the compare/contrast of war gaming with other types of analysis. Many thanks!”

Torsten Dalhöfer, Vice President, Talent Development | Credit Suisse AG

“Mark’s approach is refreshingly different from the infotainment we typically see. Mark takes you right to the core of what strategy is all about. Rather than explaining SWOT, Ansoff, and Blue Ocean for yet another time, he makes you think about how you think. It is about mental models, groupthink, and pre-conceived ideas rather than the tools you already know. His approach is not about him giving you the “right” strategy, it is about ensuring that you choose a strategy option that will achieve what you set out to achieve. As far as I am concerned, that makes much more sense than the mainstream approach. You will have to activate all your brain cells to get the maximum out of this.”

Arunabh Das Sharma, Executive President & Advisor Strategic Initiatives, Bennett Coleman and Co. Ltd. | Strategic Thinking (3-day workshop through the Indian School of Business)

“I interacted with Mark Chussil during a war game and strategy workshop he ran for our company in November 2011. I was extremely impressed by his personality, quality of thinking and preparation. This was the first time that he was visiting India and showed a great degree of cultural sensitivity which endeared him to the group. His focus on the task at hand and the outcomes needed were always sharp and he worked tirelessly to keep us all focused. I wish him all the best and hope to interact with him regularly.”

Why Strategies Fail: Human People, Biased Tools

Many of the world’s largest, most-respected companies have gone bankrupt. Why? It’s not because they were stupid, careless, or complacent; rather, it’s in spite of them being smart, careful, and dedicated. Countless other companies lose ground, miss targets, and damage careers. It doesn’t have to be that way. You can see a 30-minute version of this speech at
