Program for New Mayors: First 100 Days

Supporting recently elected U.S. mayors with leadership tools for success during their transition and first year in office

Newly elected mayors require a unique set of tools to be successful during their transition and first year in office. The Program for New Mayors: First 100 Days, developed by the Bloomberg Center for Cities at Harvard University in collaboration with the Institute of Politics at Harvard University and the U.S. Conference of Mayors, anchors on two key themes: Becoming Mayor and Building the Team and Coalitions.

Harvard professors Kimberlyn Leary and Mitchell Weiss serve as Faculty Co-Chairs of the program.

Participation

Participation for mayors is fully funded by the Bloomberg Center for Cities at Harvard University, including tuition, accommodation, airfare, and most meals.

New mayors build a trusted peer network and advance their leadership with research and learning resources from the Bloomberg Harvard City Leadership Initiative. Attendees also gain practical guidance from current and former mayors and other experts. The program is non-partisan and does not advocate specific policy positions.

Select cities also participate in the Transition Term Fellowship program, offered in collaboration with the Taubman Center for State and Local Government at Harvard Kennedy School. This program places Harvard graduate students in mayoral transition teams to add critical capacity during the two weeks in January.

The Program for New Mayors helped me understand that the first 100 days are crucial for laying the foundation of a successful administration. We're now applying that insight daily as we build the Parker administration, making every moment count. Mayor Cherelle Parker

There’s no universal handbook on how to run a city—but the Program for New Mayors will help you create your own. I still draw on the lessons I learned, especially the most important one: nothing is more vital than building a world-class team committed to driving real world outcomes. Mayor Matt Mahan

Planning for the Future, Managing the Unexpected

After a shooting at a local school four days before his inauguration, Mayor Phillip Jones pivoted his 100-day plan to focus on improving school safety and well-being. He drew on lessons from the Program for New Mayors to build strong relationships within the school district, even without formal oversight. He also managed his time strategically, using an audit tool introduced during the program. It allowed him to compare how he intended to spend time with his actual time allocation.

In addition to leading in crisis, the mayor created two positions, Chief Innovation Officer and a federal lobbyist position, to further his vision of attracting more investments to the city, fostering economic development, prioritizing public safety, and building alliances within and beyond the city council to enact transformative change.

Secrets of Successful Mayoral Transitions

Mitchell Weiss teaches public entrepreneurship at Harvard Business School and serves as a Faculty Co-Chair of the Program for New Mayors: First 100 Days. Weiss served as Chief of Staff to Boston Mayor Thomas Menino, as well as a transition adviser to Boston Mayor Michelle Wu, and is author of “We the Possibility,” a book about how local leaders can use more experimental approaches to innovate.


“One hundred days into my first term as a new mayor, reporters asked me: ‘What have you accomplished?’ I said, ‘We built a team.’ They said, ‘Yeah, yeah, yeah, but what did you accomplish?’ And I said, ‘We built a team.’ They couldn’t wrap their heads around my answer. The fact is, the team we built in the first hundred days made possible everything we achieved in the 3,000-plus days that followed.” Michael R. Bloomberg

Fostering a Culture of Teamwork and Engagement

Mayor Brett Smiley ran on a platform of improving city services, which cannot be achieved without a committed workforce. He drew on lessons from the Program for New Mayors to use his first days in office to not only build his team but also make connections with knowledgeable staff from the prior administration. During his first week in office, he put a plan in motion to boost morale among city hall workers. He started by changing all the lightbulbs and cleaning the carpets. He also made sure to visit each office in the building to get to know staff. “At first, it felt like a shock to people, but now it feels a little more normal to pop into the finance office and chat with folks,” Mayor Smiley said.


We heard really positive feedback from staff in week one that city hall is a much more pleasant place to be now. These little gestures can make people feel more valued and appreciated. Mayor Brett Smiley
