PDSA Experiment Planner & Run-Chart Template
A practical PDSA worksheet with a clear hypothesis template, step-by-step experiment plan, a small-sample data collection table, a weekly review checklist, and plain-English run-chart guidance (including interpretation rules and annotation tips). Ready to use at the frontline or convert into an interactive experiment form.
PDSA Experiment Planner & Run-Chart Template
Purpose: Run faster, rigorous frontline experiments that produce clear learning. This tool helps you plan a focused PDSA (Plan-Do-Study-Act), collect a small-but-useful set of data, and track change over time using a run chart. Use this worksheet for short improvement cycles (days to a few weeks) and scale up when you have reliable signals.
How to use this tool
- Clarify the problem and pick one measurable outcome to change.
- Write a concise hypothesis using the template below.
- Plan the PDSA: who, what, where, when, and how you will measure.
- Collect data using the small-sample form each time the process runs.
- Each week, update the run chart, annotate changes, and use the weekly checklist to decide next steps.
Quick PDSA Hypothesis Template (fill in)
We believe that [describe change] for [which patients/process population] will lead to [specific measurable improvement] measured by [measure, unit] within [timeframe] because [rationale].
Example: We believe implementing a standard triage checklist for same-day clinic calls will reduce average patient waiting time from call to scheduled appointment by 15 minutes within 4 weeks because checklists reduce triage variability.
PDSA Plan (use this as a checklist)
- Plan: What exactly are we testing? Define change idea and steps.
- Do: Who will carry out the test, when, and where? Small scale, short duration.
- Study: What data will we collect? How often? Who will review?
- Act: Based on results, will we adapt, adopt, or abandon the change?
Small-sample Data Collection Form (repeat for each data point)
Collect only what you need. Record each event or aggregated daily/shift measure depending on context.
| Date | Time | Measure (value) | Unit | Sample size / N | Who collected | Context / Notes |
|---|---|---|---|---|---|---|
| 2026-01-01 | 08:15 | 18 | minutes | 1 | J. Smith | First day of test; one patient |
| ... | ... | ... | ... | ... | ... | ... |
Weekly Review Checklist
- Have we collected the planned data each day/shift?
- Is the run chart updated with the latest points and median line?
- Are there any obvious process or measurement problems (missing data, inconsistent definitions)?
- Is the observed change consistent with our hypothesis?
- Do we need to adjust the intervention, the measurement, or the scale?
- Decision: Continue same test / Modify test / Stop and try something else / Adopt more widely
- Document actions and update the annotation on the run chart for transparency.
Run-Chart Template & Instructions
A run chart displays your measure over time. It helps you see whether a change produced a signal worth acting on. Steps to build a run chart:
- Plot time on the horizontal axis (consistent intervals: daily, shift, weekly) and the measured value on the vertical axis.
- Include at least 10 data points before relying on statistical rules; fewer points still provide useful visual learning for quick PDSAs.
- Draw the median line using baseline data (preferably the first 7–14 points if available).
- Add annotations for test start, changes, or events (label who changed what and when).
Simple Run-Chart Interpretation Rules (practical frontline rules)
- Shift: Six or more consecutive points all above or all below the median suggest a non-random change.
- Trend: Five or more consecutive points steadily increasing or decreasing suggest a trend.
- Runs: Count runs across the median; too few or too many runs can indicate non-randomness (useful when you have 10+ points).
- Outliers: Single extreme points should be investigated—were they process errors, measurement errors, or real effects?
- Use these rules as signals, not proof. Combine rule signals with operational knowledge before deciding to scale.
Annotation Best Practices
- Label each change test (e.g., Test #1 — standard triage checklist started 2026-01-08).
- Note who implemented the change and any contextual events (staffing changes, EHR downtime).
- When you adapt the test, add a new annotation rather than overwriting old notes.
Practical tips for healthcare teams
- Keep measures simple and objective (time, count, proportion) and define them clearly (what counts as a data point?).
- Train data collectors briefly and use a short written data definition to reduce measurement error.
- Start with small tests — a single clinic, one shift, or a single practitioner — then scale thoughtfully when you see reliable improvement.
- Prefer frequent, small-sample data collection over rare large audits when testing quick changes.
When to use a control chart instead
Run charts are excellent for early learning and quick PDSAs. Switch to control charts (statistical process control) when you: want formal control limits, have larger sample sizes, or plan to sustain and monitor a stable process over time. Consider consulting a quality analyst for control-chart setup.
Next steps & conversion to interactive experiment
This HTML worksheet is ready to use as a printable or digital guide. For better capture and team reporting, convert this into an interactive experiment form that:
- collects each data point via structured fields,
- stores submissions as JSON for audit/history, and
- auto-renders an up-to-date run chart with annotations.
