Participatory impact pathways analysis (PIPA) is a project management approach in which the participants in a project (project and program are used synonymously from now on), including project staff, key stakeholders and the ultimate beneficiaries, together co-construct their program theory.[1]

The PIPA theory describes plausible impact pathways by which project outputs are used by others to achieve a chain of outcomes leading to a contribution to eventual impact on social, environmental or economic conditions. Impact pathways are a type of logic model, that is, they constitute a model that describes the logic of what the project will do, is doing, or what it did.
PIPA helps workshop participants surface, discuss and write down their assumptions and theories about how their project activities and outputs could eventually contribute to desired goals such as poverty reduction. The description of these assumptions and theories is a description of the project’s (or program’s) impact pathways. PIPA has helped workshop participants with the following:
Participatory Impact Pathways Analysis (PIPA) was first used in a workshop in January 2006 in Ghana, with seven projects funded by the "Challenge Program on Water and Food".[2] Nine PIPA workshops have been held since then for 46 projects. Researchers from the International Center for Tropical Agriculture,[3] WorldFish Center [4] and International Potato Center [5] are developing PIPA.
PIPA developed from innovation histories[6] and work carried out by the Institutional Learning and Change Initiative.[7] A paper describing the approach has been accepted for publication in the Canadian Journal of Program Evaluation.
PIPA is useful when two or more projects in the same program wish to better integrate. At least two people for each project should attend, preferably the project leader and someone else who knows the project and has time and inclination to follow up on what comes out of the workshop. PIPA also works well when one project wishes to build-up common understanding and commitment from its stakeholders. In this case, two or more representatives from each important stakeholder group should attend.
PIPA can be used at the beginning of a project, in the middle or at the end as way of documenting and learning from the project. PIPA describes project (or program) impact pathways in two ways: (i) causal chains of activities, outputs and outcomes through which a project is expected to achieve its purpose and goal; and (ii) networks of evolving relationships between project implementing organizations, stakeholders and ultimate beneficiaries that are necessary to achieve the goal. The workshop process, shown in the diagram, develops the two perspectives in turn and then integrates them.
The workshop begins with participants developing a problem tree that links the project goal framed in terms of a challenge or problem to what the project is actually going to do. The approach used for developing the problem tree is based on work by Renger and Titcombe (2003). The problem tree helps participants clarify the key problems / opportunities their projects are addressing, and the outputs (things others will use) that their projects need to produce. Participants then carry out a visioning exercise, which borrows from appreciative inquiry, to describe project success 2 years after the project finishes, based on the adoption and use of project outputs. These three steps (see diagram) usually take about a day to complete and provide the information needed to describe a causal chain of outcomes needed to achieve project success.
The second part of the workshop involves participants drawing the networks of people and organizations already working in the area in which the project wishes to intervene. They then draw the networks that will be needed to achieve the project vision and identify the differences between the two networks. From these differences they identify the communication and influence strategy that the project will need to employ to be successful. The final step is to integrate the causal chain and the network perspectives by drawing a time line that lists what needs to happen from when the project starts until the vision is achieved.
An optional step, if the information is to be used for monitoring and evaluation, is to discuss how projects can monitor their progress along their impact pathways. This can involve identifying SMART criteria (specific, measurable, attributable, realistic and time bound) to measure expected change, and an approach like "most significant change" to pick up unexpected ones. A key component of any evaluation plan is that project staff periodically revisit their vision, problem trees and network maps and update them based on what they have learned, identify necessary changes to the time line and document the process.
The information from PIPA workshops has been used in a number of ways:
