1 Human Systems Engineering for Societal Transformation
A Tale of Two Cities
Nancy J. Cooke
In October of 2016, I had the great fortune of attending the International Ergonomics Association (IEA) Council meeting in MedellĂn, Columbia. I attended as president of the Human Factors and Ergonomics Society (HFES) to represent the society at this international meeting. I was excited to learn about the activities and accomplishments of human factors and ergonomics societies around the world, but little did I know that this visit would totally expand my view of the value of human systems engineering (HSE).
As part of the meeting, council members were given a âVIP tourâ of MedellĂn. The tour inspired me, to say the least. But first, some background. I learned that MedellĂn had a long and violent history. It was once the âmurder capital of the world.â In the 1980s, drug cartel leader Pablo Escobar carved out a criminal empire in the city of MedellĂn. By the early 90s, the murder rate had skyrocketed. Then things got even worse. Escobar was shot and killed by police, yet the cartel continued under new leadership. The murder rate increased as the group took on a paramilitaristic character; urban warfare was rampant.
The other stunning thing about MedellĂn is its topological divide. There are mountains surrounding the city, and rapid population growth in the 50s and 60s tripled the population. Many immigrants were farmers from rural parts of Columbia who were fleeing violence, and poorer people moved into new neighborhoods in the mountains beyond the footprint of the city. Children built on top of their parentsâ homes and growth continued in this fashion for years, creating not only a topographical divide but a socioeconomic divide (see Figures 1.1 and 1.2).
Key cultural and educational services were located in the main part of the city in the valley. Thus, the people living in the mountains had none of these services. In fact, it would take the people living at some of the highest points on the mountain a full two hours to walk into the city to go shopping, get medical attention, or find work. Conditions up the mountain were very poor. Urban violence was greater in these poor neighborhoods and gangs were prevalent. Conditions only worsened with the drug cartel violence of the 80s and 90s. There was no social equityâa visible divide between the âhavesâ and âhave nots.â

Now, back to the âVIP tour.â The tour was not of museums or fancy buildings in the wealthier part of MedellĂn. Instead, we were taken up the mountain to neighborhoods that in 1992 you would not set foot in for fear of being murdered. But we did not climb up the mountains on a two-hour hike. Instead we road on a metrocable transportation system. This was a metro or light rail to move people from the city to its edges and a cable car system (Figure 1.3) to lift you up and down the mountain. In some neighborhoods, outdoor escalators would take you on the last climb (Figure 1.4). I noticed dogs enjoying these as well!
We learned that in 2004, a program of social transformation was launched in MedellĂn. Planners, designers, politicians, university professors, and gang members collaborated on the plan. Instead of attacking the crime problem with brute forceâuse of police and armed guardsâthey came up with an innovative strategy. They would transform MedellĂn by connecting the poor and wealthy, making urban resources available to all. This was accomplished through the elaborate metrocable system, which changed the two-hour commute to a 15-minute one. They also built botanical gardens, schools, and museums in the poorest neighborhoods. Also located in these neighborhoods were âlibrary parksâ or centers for education and culture. The resources available for the âhavesâ were now available for the âhave nots.â

We were told that the plan was still being implemented, but the homicide rate had dropped, gang violence had decreased, and unemployment had decreased drastically (Vulliamy, 2013). We talked to former gang members who were proud of their neighborhoods and expressed themselves by painting beautiful graffiti murals (Figure 1.5).
What an amazing transformation! Then it hit me that this was a human system that was transformed through changes in technology and the environment; through accessibility. Penalosa (2013) has pointed out that enhanced mobility leads to equality. Behavior was changed through considerations of the needs of the people. MedellĂn became user-centered for the poorest of its people. Users (i.e., gang members) participated in the redesign of their city. I am to this day unclear as to whether human systems engineers were involved in the project, but I remain convinced that this was transformation of a human system through careful consideration of the needs of the humans in that system. Inequality was reduced through the smart use of technology and environmental design.

How can human systems engineering play a role in these sorts of transformations? I thought carefully about this as I prepared my presidential address to HFES in the following year. My trip to MedellĂn was inspirational, but I wondered how I could take this inspiration and turn it into a recipe for successful social transformation by those who are human systems engineers. I came up with three lessons learned from MedellĂn and other experiences from my past.
The first lesson is to take a problem-centric view. What is the problem that needs to be addressed? There is no shortage of problemsâincluding some very big problems. You can start with the National Science Foundationâs Big Ideas (NSF, 2017) or the National Academy of Engineeringâs Grand Challenges (NAE, 2016). Violence and inequality in MedellĂn were big problems that needed to be addressed, but sending in more police was obviously not a solution.
This brings us to the second lesson: take a systems perspective and then âblow it up.â Human systems engineers have typically adopted a systems perspective, but now they need to expand the scope of those systems. They have studied some very big systems such as the National Air Space System, military command and control systems, shipboard radar systems, and healthcare systems (Boehm-Davis, Durso, & Lee, 2015; Booher, 2003). When you avoid a myopic perspective on a problem, you might begin to see other factors at play. Muggah (2014), for instance, talks about problems regarding fast-growing cities, crime, and violence. One of the biggest factors is the increasing proportion of young people in the population. It is also important to recognize that a system is not just technology, but also includes the environment and social system. This big systems view would have had to be appreciated in the transformation of MedellĂn given that the solution was mobility for equality rather than increased policing. Once you have identified the interacting system components, new problematic factors and related solutions may become apparent.
Finally, the third lesson, and perhaps the most important one, is that no single discipline (including human systems engineering) can solve these systemic problems alone (NRC, 2015). It requires multiple disciplines, technologists, and users working together. However, human systems engineers bring together the technology, environment, and user and therefore, may have an opportunity to initiate, provide leadership, and coordinate the multidisciplinary team (Roscoe et al., in press). To me this is a very exciting prospect. Human systems engineers can lead the way in thinking out of the box and solving some of societyâs biggest problems.
I delivered the presidential address at the 2017 HFES meeting. It was nicely followed by a talk by Ron Davis, President Obamaâs appointee to the Community-Oriented Policing Task Force. Mr. Davis spoke about thinking of policing as a system embedded in the system of the community. Defining policing this way leads to new ideas for selecting and training police officers and interacting with the community. In a field typically dominated by technological systems, these two talks highlighted social systems and the role of human systems engineering in societal transformation. Many members remarked that they experienced an âaha!â moment like Iâd had in MedellĂn. They felt inspired to use their skills to address some problems not typically thought of as human systems problems. I heard discussions in the conference hall about using human systems engineering to address policing, the gender gap, child abuse, and climate change. I was very happy to have been able to share the inspiring story of MedellĂn and the lessons learned from this experience with the audience that day, and now with the readers of this volume.
