Outcome Harvesting is a method for identifying, analyzing and understanding changes that have already occurred in a system, regardless of whether they were planned, unplanned, positive or negative. Unlike traditional impact measurement, the method does not start from predetermined goals but from observed results in reality. This makes it particularly valuable in systems innovation where causal relationships are multiple, where development occurs iteratively and where changes are often unexpected and difficult to attribute to a single actor or effort.
But what is Outcome Harvesting, why is it needed in systems innovation processes and how can a systems innovation leader use the method to navigate and learn in complex change environments?
What is Outcome Harvesting
Outcome Harvesting was developed by Ricardo Wilson-Grau and is based on the idea that it is more effective to identify and understand actual changes in behaviors, relationships and structures than to measure them against predetermined indicators. The method focuses on outcomes rather than outputs and on system responses rather than activities.
An outcome is defined as an observable change in how actors act, think or interact. It could be that a municipality starts collaborating with civil society in a new way, that an authority changes its language or that a company adapts its business model to a circular logic.
Outcome Harvesting seeks answers to three central questions
- What has changed?
- Who changed?
- How do we know that the change is connected to our efforts?
It is an iterative knowledge process where mapping, analysis and interpretation take place together with those who influence and are affected by the system.
Why Outcome Harvesting is important in system innovation
System innovation is characterized by change being non-linear, distributed and difficult to predict. Therefore, traditional KPIs do not work very well. They are often too rigid, too simple and too goal-driven to capture complex dynamics.
Outcome Harvesting is important because it
- Captures both planned and unplanned changes.
- Identifies system movements even before they are visible in large indicators.
- Creates learning between actors who otherwise do not see each other’s effects.
- Makes counterforces, opportunities and early signs of shifts visible.
- Supports adaptive management where the next step is determined by what the system shows.
The method gives the system innovation leader a way to listen to the system and to understand how efforts and relationships actually affect the whole.
How to conduct an Outcome Harvesting workshop
Here is a practical method that can be used in public organizations, companies, research environments, partnerships or other system constellations.
Step 1 Formulate the change focus
Set the framework for what is to be investigated. It can be a system area such as the circular economy, sustainable mobility or innovation capacity in a sector. The formulation should be broad enough to allow for unexpected discoveries but clear enough to create a common focus.
Step 2 Gather actors and perspectives
To capture system dynamics, the workshop must include multiple actors who influence and are influenced by the system. The leader helps the groups focus on behaviors and relationships rather than activities.
Step 3 Identify outcomes
Participants answer three questions:
- What observable changes have occurred recently
- Which actors changed their actions
- What is the sign that this change has actually taken place
It is important that the changes are specific and measurable in the sense that they can be verified through observation. An example is that a real estate company changed its procurement requirements to include recycling.
Step 4 Describe the connection to efforts
Participants review each outcome and describe how their effort, project, dialogue or collaboration may have contributed to the change. The method focuses on contribution rather than attribution because system innovation is always collective.
Step 5 Analyze system patterns
When several outcomes are collected, patterns emerge. The leader helps the participants see
- What types of actors are changing
- What behaviors are shifting
- What relationships are developing
- What mechanisms are driving change
The patterns become the basis for strategic insights.
Step 6 Identify levers
By studying the patterns, the points that seem to affect the system the most are identified. These can be new norms, new roles, new processes or new forms of cooperation. These levers become guidelines for further efforts.
Step 7 Document narrative lessons
The most important result is often not the map but the story of the system. The leader helps the participants to formulate a common narrative summary that describes the state of the system and the shifts seen.
How to follow up on an Outcome Harvesting process
A system innovation process needs continuity. Outcome Harvesting is not a one-time tool but a recurring reflection of the system. Therefore, follow-up is central.
Continued follow-up can be done by:
- Conducting smaller system mappings quarterly.
- Collect indicators that are qualitative rather than quantitative.
- Conduct in-depth interviews with key stakeholders.
- Update the shared narrative of the system’s evolution.
When multiple data sources are combined, an adaptive governance model emerges where organizations can change direction in step with the system’s behavior.
How a systems innovation leader uses Outcome Harvesting
For a systems innovation leader, Outcome Harvesting is invaluable because it provides a way to
- Listen to the system’s response rather than following a static plan.
- Identify early signs of shifts that are otherwise invisible.
- Create shared understanding between stakeholders.
- Build legitimacy for change through observable evidence.
- Prioritize efforts based on where the system is actually moving.
The method helps the leader understand which efforts should be strengthened, which should be stopped, and where the most promising opportunities lie.
An example
Imagine a region that wants to accelerate the transition to circular building materials. During an Outcome Harvesting workshop, it is discovered that a number of large real estate companies have started to demand recycled materials, that schools have started to train students in circular design principles and that several entrepreneurs have started to experiment with material banks.
By analyzing these outcomes, it is seen that the most powerful lever is new forms of cooperation between municipalities and construction companies. This would never have been discovered if only traditional KPIs such as emissions data or tons of recycled material had been followed.
Understanding what is actually happening in systems
Outcome Harvesting is a method that suits complex and adaptive systems because it is based on real changes rather than planned goals. It helps system innovation leaders see patterns, understand drivers and adapt efforts based on what is actually happening in the system.
