Real-Time Delphi: A Faster Way to Build Expert Consensus
Real-Time Delphi brings the strengths of traditional Delphi research into a faster, more flexible online workflow where participants can review feedback and refine their answers while the study is still active.
A modern approach to structured expert feedback
Traditional Delphi studies are often conducted in separate rounds. Participants complete Round 1, the study team summarizes the results, and then participants are invited back for Round 2 to review feedback and reconsider their responses. This process is powerful, but it can take time.
Real-Time Delphi is a more dynamic version of the Delphi method. Instead of waiting for a round to close before feedback is prepared, participants can often see updated group feedback while the study is still open. They may then revisit and revise their responses as the group’s views become clearer.
The result is a faster and more flexible way to support expert consensus, especially when participants are busy, geographically dispersed, or working within a limited project timeline.
How Real-Time Delphi is different from traditional Delphi
Both traditional Delphi and Real-Time Delphi are designed to gather expert judgment, provide feedback, and support structured consensus-building. The main difference is how feedback is delivered and when participants can respond to it.
| Traditional Delphi | Real-Time Delphi |
|---|---|
| Often organized into clearly separated rounds. | Feedback can be updated while the study is still active. |
| Participants usually wait for the next round to review group results. | Participants may review current group feedback during the same study period. |
| The study team prepares feedback after a round closes. | Participants can often respond to emerging group patterns more quickly. |
| Useful when the study requires formal round-by-round documentation. | Useful when the study team needs a faster, more flexible consensus process. |
Why use Real-Time Delphi?
Real-Time Delphi can be especially helpful when the research team needs the benefits of Delphi methodology but wants to reduce the time and administrative burden associated with multiple separate rounds.
Faster consensus-building
Participants do not always need to wait for a new round to see group feedback. This can help accelerate the movement from individual input toward shared understanding.
More flexible participation
Experts can often participate asynchronously, review feedback, and update responses when their schedule allows.
Less round administration
Study teams may be able to reduce the operational work of closing one round, preparing feedback, and launching another round.
Useful for busy experts
Clinicians, researchers, executives, policy experts, and stakeholders may find it easier to participate when the workflow is flexible.
Supports reflection
Participants can see how their responses compare with the group and decide whether to keep or revise their views.
Good for remote panels
Real-Time Delphi works well when participants are spread across different institutions, regions, countries, or time zones.
How the Real-Time Delphi process works
Real-Time Delphi can vary depending on the study design, but a typical workflow includes the same core principles as traditional Delphi: expert input, structured feedback, reflection, and analysis of agreement.
What kind of feedback can participants see?
Real-Time Delphi studies usually provide controlled feedback. The study team decides what information participants should see and how that information should be presented.
Group statistics
Participants may see median ratings, averages, distributions, percentage agreement, or other summary measures.
Comparison to the group
Participants may see how their response compares with the current panel response.
Comments or rationale
Some studies include anonymized comments so participants can understand why others rated an item differently.
Consensus status
Items may be shown as reaching consensus, not reaching consensus, or requiring additional review.
Stakeholder differences
Some studies compare responses across expert groups, patient groups, regions, or other stakeholder categories.
Updated results
Feedback may change as more participants respond or revise their answers.
When is Real-Time Delphi a good fit?
Real-Time Delphi is not necessarily better than traditional Delphi in every situation. It is best viewed as a useful option when the study team wants a more responsive, efficient, and flexible consensus process.
Real-Time Delphi may be a good fit when...
- The panel is geographically dispersed.
- Participants are busy and need a flexible schedule.
- The project timeline is limited.
- The team wants to reduce multiple round administration.
- The study can benefit from dynamic feedback and revision.
- The goal is structured consensus, prioritization, forecasting, or decision support.
Traditional Delphi may be preferred when...
- The protocol requires clearly separated rounds.
- The team wants formal review between rounds.
- Feedback needs substantial manual analysis before the next round.
- The study requires extensive item refinement between rounds.
- The publication strategy depends on round-by-round documentation.
- The topic requires slower deliberation or steering-committee review.
Common uses of Real-Time Delphi
Real-Time Delphi can be used in many of the same areas as traditional Delphi, especially when the study team needs expert input but wants to move more quickly.
Clinical and medical consensus
Support expert agreement around recommendations, care pathways, appropriateness criteria, or research priorities.
Core outcome sets
Help stakeholders rate, prioritize, and refine outcomes for research, registries, or clinical trials.
Policy and public health
Gather structured input from experts and stakeholders when decisions are complex or evidence is evolving.
Technology and forecasting
Assess future trends, risks, opportunities, adoption barriers, or strategic priorities.
Education and competencies
Build agreement around learning objectives, professional standards, curriculum needs, or training expectations.
Organizational planning
Support decision-making when input is needed from distributed teams, advisors, experts, or stakeholders.
Real-Time Delphi still needs good study design
Speed should not come at the expense of quality. A Real-Time Delphi study still requires careful planning, including clear objectives, appropriate panel selection, well-written items, suitable rating scales, meaningful feedback, and predefined rules for interpreting results.
The technology can make the process faster and easier to administer, but the credibility of the study still depends on sound methodology.
Clear objectives
The team should define what kind of consensus, prioritization, or decision support the study is intended to produce.
Thoughtful feedback
Participants should receive feedback that is useful, understandable, and not overly persuasive.
Transparent analysis
Consensus criteria and reporting methods should be defined clearly before results are interpreted.
How Surveylet supports Real-Time Delphi
Surveylet was designed to support Delphi and Real-Time Delphi studies, including studies that require expert panels, structured feedback, response revision, consensus-oriented analysis, and online administration.
For study teams, this means Real-Time Delphi can be managed in a platform built around consensus workflows rather than a general-purpose survey tool.
Expert panel workflows
Support invited participants, stakeholder groups, reminders, and online response tracking.
Structured feedback
Help participants review group results and reconsider their responses in a controlled, study-specific workflow.
Consensus-oriented exports
Support analysis and reporting for research teams, steering committees, and publication workflows.
Need a faster way to build expert consensus?
Surveylet helps researchers and organizations manage Delphi and Real-Time Delphi studies online, including expert panels, structured feedback, response tracking, and consensus-building workflows.
