The Four-Stage Change Process: A Practical Framework for Lasting Social Change

So you understand systems thinking. You can spot the archetypes. You know why good intentions backfire. Now what? How do you actually use this stuff to change things?

That’s the question Chapter 5 of Systems Thinking for Social Change answers. And it starts with a real story.

When a County Decided to End Homelessness

In 2006, David Peter Stroh and Michael Goodman helped community leaders in Calhoun County, Michigan, develop a ten-year plan to end homelessness. The county had about one hundred thousand people, years of leadership gridlock, and constant fighting over what to do about the problem.

What made this project different from the dozens of failed attempts before it? Two things happened at the same time.

First, they brought the right people together. Government officials at the local, state, and federal levels. Business leaders. Service providers. And homeless people themselves. Everyone who had a stake in the problem was in the room.

Second, they gave those people a way to think together about the system. Not just share opinions. Not just negotiate. But actually build a shared picture of why homelessness kept persisting.

The result was a big shift in how the community saw their own services. Temporary shelters and emergency programs had always been treated as part of the solution. But when people mapped the system, they realized these programs were among the key obstacles to ending homelessness. The system was designed to help people cope with being homeless, not to end homelessness.

Service providers who used to compete for funding started working together. In one case, they unanimously agreed to move HUD funding from one provider’s temporary housing program to another provider’s permanent supportive housing program. That kind of cooperation doesn’t happen without a shared understanding of the bigger picture.

The results held up even when the 2008 recession hit. Between 2007 and 2012, homelessness in Calhoun County dropped 14 percent despite a 34 percent jump in unemployment and a 7 percent rise in evictions.

Two Things That Usually Happen Separately

The Calhoun County story reveals a pattern that Stroh and Goodman noticed across years of work. Most change efforts do one of two things well, but rarely both.

Convening people systemically means getting the right stakeholders in the room. The past twenty-five years have produced a lot of tools for this: Future Search, Open Space Technology, the World Cafe, Collective Impact, Theory U, Social Labs. These approaches bring diverse voices together and create space for dialogue.

Thinking systemically means using systems thinking tools to help those people see the bigger picture they’re all part of. It gives people what Otto Scharmer (creator of Theory U) calls a “collective sensing mechanism.” Everyone can see how they not only support the system but also often unknowingly undermine it.

Most projects pick one or the other. They either bring people together without giving them tools to see the system, or they do great systems analysis without involving the right stakeholders. The four-stage process combines both.

The Creative Tension Model

Before getting into the four stages, Stroh explains where the framework comes from. It’s built on Peter Senge’s “creative tension” model from The Fifth Discipline.

The idea is simple. Energy for change comes from the gap between what people want and where they actually are. If a group can hold onto a clear vision of the future and be honest about current reality, the tension between those two points naturally pulls toward the vision.

But here’s the critical addition that Stroh and Goodman make. At the collective level, it’s not enough to agree on where you are. You also need to understand why you’re there.

This matters because stakeholders often agree on surface-level observations. Everyone in Calhoun County could see they had a homelessness problem. That’s the tip of the iceberg. But they disagreed on causes and solutions because they couldn’t see the underlying system structure that affected all of them.

When people develop a shared picture of both what they want and why things are the way they are, something shifts. They stop thinking about just their role and start feeling responsible for the whole system. Instead of “I’ll do my part,” they say, “I’ll do my part and make sure we all get the whole thing done.”

The Four Stages

Stroh and Goodman expanded the creative tension model into a four-stage change process. They developed it over fifteen-plus years of working with hundreds of executives and change agents. Here’s what it looks like.

Stage 1: Build a Foundation for Change

The goal here is collective readiness. You’re not solving the problem yet. You’re making sure the right conditions exist for problem-solving to work.

Three things need to happen:

Engage key stakeholders. Figure out who needs to be involved and design strategies to bring them in, both individually and as a group.

Establish common ground. Create initial pictures of what people want to achieve and where they are now. Build an early shared vision and take stock of what’s working and what isn’t.

Build capacity to collaborate. Teach people to think systemically and have productive conversations about hard topics. Also help them develop the underlying willingness to take responsibility for current reality. That last part is harder than it sounds.

In Calhoun County, this meant bringing leaders from all three sectors together with homeless people, doing shared visioning exercises, and introducing systems thinking tools early on.

Stage 2: Face Current Reality

This is where the real work begins. The goal is a shared understanding of what’s happening and why, plus acceptance that everyone has played a role in creating the current situation, even if they didn’t mean to.

You might think the next logical step after Stage 1 would be building a richer vision of the future. But Stroh and Goodman found something important: people need to understand and feel understood about where they are before they’re ready to move forward. As Otto Scharmer put it, the primary job of leadership is to “enhance the individual and systemic capacity to see, to deeply attend to the reality that people face and enact.”

The tasks in Stage 2 include:

• Interview people about the history of the current situation
• Organize and improve the quality of the information
• Develop a preliminary systems analysis of how different factors interact over time
• Engage people in building their own analysis (not just presenting yours to them)
• Surface the mental models that drive behavior
• Create conversations that spark awareness, acceptance, and alternatives

In Calhoun County, Stroh and Goodman interviewed fifty leaders from across all sectors plus homeless people. They built an initial systems map, tested it with a small design committee, and then shared the refined analysis with a wider steering committee.

Stage 3: Make an Explicit Choice

This stage forces a moment of truth. The goal is conscious commitment to a shared aspiration, with full awareness of what it will cost.

Here’s what that looks like in practice:

Identify the case for the status quo. Stage 2 will have uncovered the short-term benefits of the current system. Quick fixes that work for now. The comfort of doing what’s familiar. The immediate gratification of visible action.

Compare it to the case for change. What are the benefits of actually solving the problem? What are the costs of not changing?

Look for both/and solutions. Can you keep some benefits of the current system while pursuing real change? If not, be willing to make hard trade-offs.

Choose explicitly. Bring the choice to life through a vision that people feel genuinely called toward.

The turning point in Calhoun County came when stakeholders saw clearly that their system was designed to help people cope with homelessness, and that this design actively undermined their stated goal of ending homelessness. Seeing that contradiction forced a real choice.

Stage 4: Bridge the Gap

Now you connect the aspiration from Stage 3 to the reality from Stage 2. This is about finding high-leverage interventions and setting up ongoing learning.

The work has two main parts:

Propose and refine high-leverage interventions. This includes increasing people’s awareness of how the system works now, rewiring causal feedback relationships, shifting mental models, and reinforcing the new purpose through updated goals, metrics, incentives, authority structures, and funding.

Establish continuous learning and outreach. Keep existing stakeholders engaged. Develop an implementation plan with demonstration projects as part of a longer road map. Refine data collection based on new goals. Evaluate and revise regularly. Expand stakeholder involvement and scale up what works.

In Calhoun County, the leverage points became the goals of their ten-year plan. Over time, more people got involved, including stakeholders from economic development, affordable housing, foster care, and the criminal justice system.

This Is Not a Straight Line

The four stages are numbered, but the process isn’t purely linear. Lessons from Stage 4 feed back into a new Stage 1. The whole thing is circular.

Stroh makes a point that’s worth sitting with: “The shortest distance between two points is indeed a circle.” Allowing enough time for the process matters more than rushing through the stages in order.

How This Differs from Typical Change Management

Most change management approaches go something like: define the problem, set goals, brainstorm solutions, pick one, implement it. The focus is on action. Get things moving. Show results.

The four-stage process is different in a few important ways.

It prioritizes understanding over action. Two of the four stages (building a foundation and facing current reality) happen before anyone proposes a solution. That feels slow. But it’s the reason solutions actually stick.

It asks people to accept responsibility. Not blame. Responsibility. There’s a difference. Blame says “you caused this.” Responsibility says “we all contribute to this system, and we can all contribute to changing it.”

It combines process with analysis. It’s not just about getting people in a room (convening). It’s not just about building a systems map (thinking). It’s about doing both at the same time, so the analysis belongs to everyone, not just the consultants.

It respects why the current system exists. Instead of treating the status quo as the enemy, Stage 3 acknowledges that the current system has real benefits. People aren’t stupid for maintaining it. They’re making rational short-term choices. The process helps them see the long-term costs and make a conscious trade-off.

Why Understanding “Why” Comes Before “What”

If there’s one idea that defines this chapter, it’s this: you have to understand why things aren’t working before you try to fix them.

That sounds obvious. But it’s the opposite of how most organizations and communities operate. The pressure to act is enormous. Funders want results. Politicians want visible progress. People are suffering right now.

But acting without understanding is exactly how you end up with fixes that backfire, burdens that shift, and goals that drift. All those archetypes from the previous chapters? They persist because people skip the “why” and jump straight to “what should we do?”

The four-stage process is a structured way to resist that temptation. It’s been tested over fifteen-plus years by Stroh and Goodman across hundreds of change efforts. It works. But it requires patience, honesty, and a willingness to see your own role in the problem.

That’s the hard part. And it’s also the part that makes lasting change possible.
