Data Makes A Resident Service Platform Go From Good to Great

At a Glance


Evaluated the City’s resident services chatbot, found room for improvement and made changes that reduced response times by 50% and saved $8.5 million MXN


Visited 9,000 homes in 18 priority neighborhoods to interview caregivers about what services they needed. Services included transportation, grocery assistance and weekly breaks from caregiving. On average, caregivers in the resulting program reported a 30-point improvement in well-being after five weeks.


In response to feedback from caregivers, the City created—and then expanded—a mini public transportation route with 14 stops.


Reduced park maintenance costs by centralizing park management with a public-private partnership.

In February 2020, San Pedro Garza García launched a WhatsApp-based, resident service chatbot called Sam Petrino, or “Sam” for short. Previously the City received service requests – about potholes, broken street lights, overflowing garbage bins and more – by phone, through its website or in person at City Hall. But the Office of Innovation and Citizen Participation believed more residents would engage if they could use WhatsApp, the most common communication platform in Mexico.

They were right. Within two weeks of its launch, Sam was receiving more reports than any of the other reporting methods. Then the COVID-19 pandemic hit, and Sam’s purpose evolved. The City expanded Sam to include options for requesting food assistance or other support, reporting domestic violence, making donations or volunteering, and, eventually, registering for vaccines. By the end of 2020, Sam was averaging over 1,000 reports each month and gaining international acclaim, including receiving the National Institute of Transparency’s Innovation Award.

The City could have called Sam a success and shifted into autodrive. But, in 2021, data showed that Sam was not working as well as it could. The flood of new reports was creating internal problems, response times were slow, resident satisfaction was dropping, and the data being gathered through the chatbot was stuck in silos. The City interviewed staff, reviewed processes and made changes.

The entire government is, so to speak, connected to the bot.

Mayor Miguel Treviño de Hoyos

The City made 15 improvements to the Sam Petrino chatbot.

The City re-engineered Sam, making more than 15 improvements. Now, Sam is fully automated and digitized, internal reporting operations have been streamlined, and the public has clear accountability channels. Data from Sam is reliably gathered, shared across departments and publicly, and used in decision making.

The result: Despite 110% more citizen service reports submitted in 2023 than in 2019, the City responded 8.6 times faster – sometimes within hours – with the same amount of staff and the same amount of funding. Citizen satisfaction with Sam and the City’s response to service requests has increased from 67% before the changes to 84% after the changes were implemented. The majority of City staff also approve of the new internal processes behind Sam, which have helped foster accountability and recognition for those responding to the reports.

The City’s willingness to listen to the data, its residents and staff allowed it to see that even award-winning innovations can be improved. It’s a successful approach San Pedro Garza García is now broadly applying to better serve its residents.

What I would tell all other mayors is, ‘If your resources are scarce – which they are – you have to understand what you are achieving with these resources. And the only way to do that is to measure what you are doing.’

Improving Quality of Life Through a Data-Driven, Resident-Oriented Municipal Budget

At a Glance


5% of the City’s annual real estate tax is allocated to projects proposed by residents through the Participatory Budget.


10,254 of votes cast by residents in 2023 for participatory budget proposals in 2023—five times higher than votes cast in 2022.


313 project proposals submitted by residents for the 2024 participatory budgeting round.


30 projects funded in 2023.

In late October 2023, Monterrey residents and city leaders gathered at the Rube Bridge in the Bella Vista neighborhood to celebrate a resident-led transformation. A once nondescript concrete underpass, which many neighbors avoided due to open-air drug use and loitering, was inaugurated as a recreational space featuring a soccer field, basketball and tennis courts, modern lighting and benches. Plans for security cameras, a playground and murals are in the works.

This revitalization is the result of the City of Monterrey’s participatory budgeting (PB) program, which allocates five percent of annual property tax receipts to fund resident proposals each year. Launched in 2022, the proposal is part of the city’s growing commitment to collaborative government and data-driven decision making.

Here’s how it worked:

  1. A resident of the Bella Vista neighborhood submitted a proposal to revitalize the bridge underpass.
  2. The City approved the proposal and included it on the ballot.
  3. Voters approved related proposals in 2022 and 2023.
  4. Bella Vista neighbors formed a committee to review construction project bids and monitor work site progress. (The commitment to this project from Bella Vista residents is remarkable—residents helped keep construction materials secure by sleeping at the construction site.)

Residents are clearly powering Monterrey’s participatory budgeting process—and behind the scenes, so is data. To ensure that wealthy enclaves don’t receive a disproportionate amount of funding, the City divided Monterrey into 30 sectors based on their respective socioeconomic conditions. It then prioritized funding projects in vulnerable areas. Additionally, the amount of funds made available to a particular proposal depends on four factors: the number of inhabitants of the area, the correct payment of property taxes, the level of segregation and the amount of active neighborhood councils in a sector. All proposals put up for vote must also meet technical and legal requirements, as well as being aligned to the City’s strategic goals.

One signal of the PB program’s success? Its growing popularity. In 2022, residents proposed 265 projects, of which 160 were accepted by the City; 2,452 residents ultimately approved 30 to receive funding. Last year, the City received 280 proposals, with 172 deemed feasible and 30 selected by voters. More than four times as many people (10,254) voted on those projects, thanks in part to a city communications campaign that drew on results from a performance analysis of the PB program’s first year.

Today, with civically active residents and an administration that routinely uses data to identify and prioritize local needs, progress is happening in Monterrey. Across the city—the first in Mexico to earn What Works Cities Certification—public spaces are being rehabilitated and reforested, and mobility infrastructure is being made safer. This is what smart, open government looks like in action.

“By having transparency mechanisms in place so citizens can understand how we use resources and make decisions with data, we’re promoting collaboration between society and government. It’s about being able to understand and recognize what can be improved. If we don’t listen to citizens, we lose a fundamental way to keep growing and improving.”

“As leaders we have to make decisions every day, otherwise things can fall apart. Whatever our intentions, data helps us know what to do. When you have data, you know you are making a good decision.”
