Assembling a senior team that really complements one another is one of the biggest challenges facing any CEO or business leader. After all, your fellow senior executives must lead and inspire their own teams effectively, while this mix of personalities also needs to work together seamlessly to consistently achieve great results for your business overall, including dealing with difficult strategic issues that will determine the long-term future of the business. Getting this mix wrong can conversely have a disastrous impact on the performance of your organisation. Interestingly, research I recently read indicated that personality mismatch was far and away the main reason behind unsuccessful hires, accounting for 81% of failures. That’s a remarkable statistic so it’s worth exploring why this goes wrong so often.
