How Different Industries/Disciplines Approach Complex Problems

My experience working across engineering, design, and healthcare has given me the opportunity to see how people in different fields approach complex problems.

Over time, I began to notice that each industry has developed its own way of understanding complexity and finding solutions.

Engineering: Breaking a Large Problem into Smaller Parts

Engineers are trained to break a complex system into smaller, more manageable parts.

Take an automobile as an example. A car is a highly complex system made up of many interconnected components, including the engine, transmission, suspension, body, interior, and electronic systems, etc.

To understand and develop such a complex system, engineers often study individual parts and their relationships with one another. The output from one component can become an input for another.

For example, the engine produces torque, which becomes one of the inputs for the transmission. The transmission also depends on other inputs, such as information from sensors and electrical power for its electronic components.

By breaking a large system into smaller parts, engineers can study each area more closely. When a problem occurs, this approach can make it easier to identify possible causes, test variables, and trace the source of the issue.

In simple terms, engineering often approaches complexity by asking:

How can we break this problem into smaller pieces so we can better understand and solve it?

Design: Stepping Back to See the Bigger Picture

Design often begins from a different starting point.

Urban planning is a good example. Before deciding where to place buildings, roads, or parks, designers first need to understand the people who will live and interact within that environment.

Who are we designing for?

How do different people spend their day?

What do they need to live, work, and thrive in this community?

Housing, transportation, grocery stores, schools, parks, and recreational spaces may all play a role. But designers also need to understand how these elements relate to one another—and how people interact with the environment around them.

Rather than starting with one isolated part, designers often take a step back to understand the broader picture and the relationships within it.

This approach can reveal challenges and opportunities that may not be visible when looking at individual systems separately.

Design often begins by asking:

Who are we designing for, and how does everything connect to their experience?

Healthcare: Living with Complexity

Healthcare faces some of the most difficult problems in our society.

Some of these are often described as wicked problems—problems that do not have a clear definition, a single cause, or one correct solution. The situation can also change as people, organizations, policies, and other conditions change.

The nursing crisis is one example.

There is no single reason for the challenge, and no single organization can solve it alone. Many factors are connected, including:

• Workforce shortages

• Burnout and moral distress

• Compensation

• Staffing and workload

• An aging population and growing demand for care

• Nursing education capacity

• Faculty shortages

• Retention and career development

• Technology and administrative burden

• Workplace culture and leadership

• Geographic differences

• Financial pressures on healthcare organizations

• Patient safety and quality of care

The challenge is that solving one problem can sometimes create another.

For example:

Increasing staffing may reduce workload and improve the experience of both nurses and patients—but it can also significantly increase labor costs for healthcare organizations.

There is rarely one solution that permanently solves everything.

Instead, complex challenges often require us to look at the system as a whole, identify where change may have the greatest impact, try different approaches, learn from what happens, and continue adapting.

The question becomes:

How do we make progress when everything is connected and the problem continues to change?

Different Industries, Different Habits of Thinking

Of course, no discipline or industry uses only one approach. Engineers consider the bigger picture. Designers work within constraints. Healthcare professionals analyze data and break down problems.

But over time, do industries develop strengths in certain ways of thinking? After years of education and practice, will approaches shape how people naturally see and solve problems?

Engineers may become especially skilled at breaking complex problems into smaller parts. Designers may be trained to step back and consider the whole experience. Healthcare professionals often learn to work within systems where many factors are deeply connected and constantly changing.

Is my assumption reasonable? In my next post, we’ll take a closer look at the tools and methods used by these different disciplines.

At BraidBloom, we help organizations navigate complex challenges through human-centered design.
