A systematic review reveals that the most effective Participatory Design (PD) processes involve stakeholders iteratively across multiple stages, using a variety of techniques, to ensure equitable outcomes. This user-centred design research insight is drawn from a 2025 study published in Design Science. Using Systematic literature review, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Integrate iterative and varied stakeholder engagement throughout the entire design lifecycle to ensure equitable outcomes and a more user-centered final product.

Key Findings

  • 01Stakeholders most frequently participate throughout multiple stages of a design process.
  • 02A variety of recruitment methods are used for stakeholders.
  • 03Multiple participatory techniques (out of 14 identified) are often employed.
  • 04Five key leverage points impact design equity: emergent vs. predetermined processes, direct vs. indirect participation, early vs. late participation, one-time vs. iterative participation, and singular vs. multiple PD techniques.

Application

Design takeaway

Integrate iterative and varied stakeholder engagement throughout the entire design lifecycle to ensure equitable outcomes and a more user-centered final product.

How to apply

When planning a design project, map out specific points for stakeholder involvement at various stages, considering different methods of engagement (e.g., workshops, interviews, co-creation sessions) and plan for iterative feedback loops.

Project actions

  • 01Clearly define the roles and expected contributions of stakeholders at each stage of your design project.
  • 02Document the iterative feedback process and how stakeholder input influenced design decisions.

Method & Evidence

AimWhat are the key characteristics and leverage points of effective Participatory Design processes that promote design equity?
MethodSystematic Literature Review
ProcedureThe researchers conducted a systematic review of existing literature on Participatory Design (PD) to identify common processes, techniques, and engagement levels. They analyzed case studies to understand how stakeholders are involved throughout the design lifecycle and identified five key leverage points influencing design equity.
ContextDesign disciplines, particularly the design of intangible systems.

Strengths & Limitations

Strengths

  • +Comprehensive systematic review covering a broad range of PD literature.
  • +Identification of actionable leverage points for improving PD practice.

Limitations

It can be challenging to recruit and retain stakeholders for iterative engagement due to time constraints and potential participant fatigue.

Reliability & validity

The reliability of the review depends on the systematic search and inclusion criteria. Validity is supported by the synthesis of findings across numerous studies, but the interpretation of 'design equity' can be subjective.

Think critically

How can designers balance the need for emergent, flexible processes with the practical constraints of project timelines and budgets when implementing iterative stakeholder engagement?

05

Design Principles

"Design equity is fostered through continuous, multi-faceted stakeholder collaboration."

Understanding the nuances of stakeholder involvement in PD is crucial for creating designs that truly meet user needs and societal expectations. This research provides a framework for practitioners to critically evaluate and refine their engagement strategies, moving beyond ad-hoc methods towards more robust and equitable design practices.

06

What This Means for Your Design

To make designs that work for everyone, designers need to talk to and work with the people who will use the design many times, not just once, and use different ways to get their ideas.
