Key Findings

  • 01Best-Worst Scaling (BWS) is increasingly being used in Africa for stakeholder preference research.
  • 02The method has demonstrated broad applicability across various sectors, including agriculture and health.
  • 03Studies using BWS in Africa are generally of high quality and policy relevance.
02

Application

Design takeaway

When designing policies or products for diverse user groups, especially in resource-constrained environments, consider employing Best-Worst Scaling to rigorously identify and prioritize key preferences and trade-offs.

How to apply

When faced with multiple design options or policy interventions, use BWS to ask stakeholders to identify the 'best' and 'worst' options from a set of attributes, allowing for a quantitative ranking of preferences.

Project actions

  • 01When exploring user preferences for a design project, consider how you can ask users to make trade-offs between different features or benefits.
  • 02Think about how to present choices to users in a way that makes it clear what they are comparing.
03

Method & Evidence

AimTo explore the application and utility of Best-Worst Scaling (BWS) in eliciting stakeholder priorities for policy decision-making within the African context.
MethodLiterature Review
ProcedureA systematic literature review was conducted to identify and analyze published studies that utilized Best-Worst Scaling (BWS) for prioritization purposes in Africa. The review documented the sectors of application, methodological choices, and policy relevance of these studies.
ContextPolicy development and stakeholder engagement in African nations, across sectors such as agriculture, health, business, environment, and transportation.

Variables

IVMethod of preference elicitation (Best-Worst Scaling vs. other methods).
DVStakeholder priorities and policy relevance.
CVSector of application (e.g., health, agriculture), geographical region within Africa, study quality.
04

Strengths & Limitations

Strengths

  • +Provides a structured and quantitative approach to preference elicitation.
  • +Effective in identifying trade-offs between competing attributes or options.

Limitations

The effectiveness of BWS can depend on the clarity of the options presented and the cognitive load placed on participants. Ensuring a representative sample of stakeholders is crucial.

Reliability & validity

Reliability can be assessed through the consistency of participant choices across different choice sets. Validity is supported by the method's theoretical grounding in choice modeling and its demonstrated ability to predict real-world choices or inform policy.

Think critically

How might the cultural context of different African regions influence the interpretation of 'best' and 'worst' in a Best-Worst Scaling exercise, and how could this be addressed in the design of the study?

05

Design Principles

"Prioritize stakeholder preferences through structured elicitation techniques to ensure design relevance and impact."

Understanding the nuanced priorities of various stakeholders is fundamental to designing effective and adopted policies. BWS offers a structured approach to uncover these preferences, ensuring that policy development is grounded in the needs and values of the intended beneficiaries and implementers.

06

What This Means for Your Design

This research shows that a method called 'Best-Worst Scaling' is really good at finding out what people in Africa care about most when making important decisions, like for health or farming policies. It helps make sure policies are made with people's real needs in mind.

How to use in your project

  • 1.Reference this study when discussing the importance of user research and preference elicitation in your design project.
  • 2.Use the findings to justify the selection of a method for gathering user feedback in your design process.
