Transitioning from a senior technical or executive role to a leadership position is one of the most challenging steps in a career in science, technology, engineering, or mathematics (STEM). This shift involves moving from making individual decisions to mentoring others, making strategic choices for the organization, and working with colleagues from different generations. This change in mindset is often called "legacy leadership," a concept where success is measured not by personal accomplishments but by how effectively a leader empowers others. To help experienced professionals navigate this transition, the inaugural IEEE International Leadership Conference (ILC) will offer practical advice on collaboration and guiding emerging talent. Jeewika Ranaweera, cochair of the IEEE ILC program committee, explains that early in a STEM career, success is measured by personal achievements, but later it should be measured by how many people a leader mentors and how much knowledge they share. For many seasoned technologists, shifting from being valued for their technical skills to being measured by their influence on others can feel uncomfortable. Legacy leadership requires a new set of standards, such as a leader's impact on their team, their ability to uphold the organization's mission, and their capacity to empower others. This transition also means finding purpose beyond corporate titles, focusing on the long-term sustainability of teams, organizations, and the broader technical community. Sudhanshu S. Jamuar, another program committee cochair, emphasizes that a professional legacy is not only about what one has achieved but also about sharing knowledge and opportunities with others. He notes that the real shift from expert to leader happens when one stops focusing on personal accomplishments and instead considers how many others can be enabled to achieve more. True knowledge transfer in leadership requires more than just giving advice—it involves coaching and active listening. Senior leaders must build trust with early-career colleagues and ensure a smooth transition of leadership by avoiding outdated or irrelevant advice. Effective mentorship is a two-way process where experienced professionals share their hard-earned knowledge while remaining open to new ideas from younger colleagues. Sudeendra Koushik, president of the IEEE Technology and Engineering Management Society and an ILC keynote speaker, highlights that knowledge transfer is most powerful when it flows both ways. This approach transforms mentorship into a dynamic exchange where the next generation can question, innovate, and surpass previous achievements. Neeli Rashmi Prasad, IEEE ILC treasurer and sponsorship cochair, adds that legacy leadership is about building continuity, not just preparing the next generation to follow existing paths but giving them the confidence to create new ones. Leadership can continue long after a job ends. Retired professionals can contribute meaningfully through advisory roles, community engagement, or mentoring programs. These opportunities allow experienced individuals to redefine success not by position or authority but by the lasting impact they create. Koushik emphasizes that retirement should not mean the end of purpose, and that using experience to serve the profession and society is especially valuable. At the same time, emerging leaders must take initiative in building their networks. Prasad advises young professionals to be bold, stay curious, and establish connections early in their careers. The IEEE International Leadership Conference is designed to bring together seasoned leaders and emerging innovators to foster collaboration and knowledge-sharing. Unlike a traditional classroom setting, the conference includes a dedicated track for career readiness and mentorship, offering practical tools for building professional networks and engaging in cross-generational learning. By participating, experienced professionals can ensure their expertise continues to benefit future generations. Ranaweera concludes that a true professional legacy lies not in titles or awards, but in the knowledge shared, the lives influenced, and the future shaped for others.
