As chief innovator and problem solver, the CTO's value far exceeds technology skills. The CTO must lead as a highly visible, first-class citizen of the C-suite. Still, many technology experts operate in a reactive, support-oriented style, struggling to command respect or assert influence-let alone executive presence. Whether setting the tone as a new hire or looking to redirect or revitalize an established role, one hundred days are all you need to secure long-term success. In CTO Excellence in 100 Days: Becoming the Leader Your Company Deserves, Etienne de Bruin offers actionable guidelines on how to lead both your company's technology strategy and the people behind it. The work begins with assessing whether you're in the right place. Next, Etienne's methodical approach helps you build trust and visibility through effective communications and a strategic quick win, introduce your company's technology vision, and navigate challenges-from engaging stakeholders to managing conflict-all within that vital one-hundred-day period.
