All initiatives use the same goal, period and units.
RICE Scoring
A practical method guide: clarify prerequisites and materials, understand the complete process, and look up outputs, pitfalls, and stop criteria.
Prerequisite
What needs to be finished first
Each factor has evidence or explicit assumptions; people doing the work help estimate effort.
Preparation
What needs to be ready before start
Shared scoring table, clearly described initiatives, usage data, customer evidence and effort estimates.
Product · domain and customer perspective · Engineering · decision owner
Gather initiatives, usage data, impact hypotheses and effort ranges. Record the period, source and uncertainty.
60–90 minutes for a prepared comparison; research separately.
Use one row per initiative. Reach counts affected people in the chosen period. Impact expresses the effect per person on the shared goal. For example, use Intercom’s scale of 3 / 2 / 1 / 0.5 / 0.25. Enter Confidence as a percentage, such as 100 / 80 / 50 for different levels of supporting evidence. Effort covers total work in person-months and must be greater than zero.
Core question
The one question this method answers
Which initiative promises the greatest expected contribution to our goal relative to effort?
Flow
Phases with goal, actions, output and pitfall
RICE ranks initiatives by reach, impact, confidence, and effort. The score supports shared prioritisation and makes uncertainty and justified exceptions visible.
Calculate RICE with consistent assumptions
Fictional worked example
Fictional example: two improvements to a booking app compared over the same quarter. All numbers are invented.
RICE = Reach × Impact × (Confidence / 100) / Effort
| Initiative | Reachpeople / quarter | Impactfactor | Confidence% | Effortperson-months | Score |
|---|---|---|---|---|---|
| Simplify booking | 1,200 | 2 | 80% | 4 | 480 |
| Add reminders | 600 | 3 | 50% | 2 | 450 |
- Simplify booking: Evidence
- Fictional: usage data and several interviews; effort estimated together.
- Add reminders: Evidence
- Fictional: bounded reach; high impact is still only an assumption.
480 is slightly ahead of 450. If booking effort rises from 4 to 6 person-months, its score drops to 320. The ordering depends on an uncertain assumption.

Frame
Frame the comparison

Goal
Every row answers the same decision question.
Inputs for this step
- Prioritization question
- Described initiatives
Actions
- Agree on one shared goal and period.
- Align scope, reach units and effort units across all rows.
Output
Comparison frame
Goal · period · units
Quality check
Are the initiatives meaningfully comparable?
Pitfall
One initiative counts annual users, another quarterly users. Use the same period for every value.
Timing: 10–15 minutes as a guide.
- 2
Impact
Estimate Reach and Impact

Goal
Expected impact has a traceable basis.
Inputs for this step
- Usage data and customer evidence
Actions
- Estimate affected people in the period and record the source.
- Estimate impact per person on the shared goal using the agreed scale.
Output
Impact estimate
Reach · Impact · evidence
Quality check
Is reach counted only once? Does impact refer to the same goal?
Pitfall
Large reach is also treated as high impact. Estimate impact per affected person.
Timing: 15–20 minutes with prepared data.
- 3
Evidence
Add Confidence and Effort

Goal
All four factors use consistent, justified estimates.
Inputs for this step
- Evidence quality
- Estimates from those doing the work
Actions
- Set confidence from the supporting evidence and enter it as a percentage.
- Estimate total effort across roles in person-months and record uncertain ranges.
Output
Complete factors
Confidence · Effort · assumptions
Quality check
Is confidence grounded in evidence? Is effort positive and complete?
Pitfall
Enthusiasm replaces evidence; effort covers implementation alone. Label evidence and include required analysis, design and implementation work.
Timing: 15–20 minutes for a prepared scope.
- 4
Review
Check score and sensitivity

Goal
The ranking is mathematically correct and uncertainty is visible.
Inputs for this step
- Four factors per initiative
Actions
- Divide Reach × Impact × (Confidence / 100) by Effort.
- Vary uncertain inputs across plausible ranges and check for ranking changes.
Output
Reviewed ranking
Score · range · ranking changes
Quality check
Is 80 percent calculated as 0.8? Does the ordering survive plausible changes?
Pitfall
Decimal places suggest precision the estimates do not support. Check a decision-relevant effort range and show its effect.
Timing: 10–20 minutes.
- 5
Decision
Set a justified priority

Goal
The next step and its reasons are traceable.
Inputs for this step
- Reviewed ranking
- Dependencies and commitments
Actions
- Review results against dependencies, strategic goals and mandatory commitments.
- Record priority, justified exceptions, owner and review date.
Output
Prioritization decision
Priority · reasons · owner · review date
Quality check
Are exceptions to the score explained? Is the next review clear?
Pitfall
The highest number becomes a binding commitment without context. Document score and decision separately, with relevant reasons.
Timing: 10–15 minutes.

- Advance information: Gather initiatives, usage data, impact hypotheses and effort ranges. Record the period, source and uncertainty.
- Overall time needed: 60–90 minutes for a prepared comparison; research separately.
- Setup: Use one row per initiative. Reach counts affected people in the chosen period. Impact expresses the effect per person on the shared goal. For example, use Intercom’s scale of 3 / 2 / 1 / 0.5 / 0.25. Enter Confidence as a percentage, such as 100 / 80 / 50 for different levels of supporting evidence. Effort covers total work in person-months and must be greater than zero.

Calculate RICE with consistent assumptions
RICE = Reach × Impact × (Confidence / 100) / Effort
| Initiative | Reach (people / quarter) | Impact (factor) | Confidence (%) | Effort (person-months) | Score | Evidence |
|---|---|---|---|---|---|---|
Agree on the same period, goal and units before entering values. Enter Confidence as a percentage. Record sources and open assumptions for each initiative; Effort must be greater than zero.

Example output
Concrete filled scenario, fictional example
Fictional example for orientation. Counts and timings describe this case and are not universal requirements.
rice-beispiel.md
Concrete filled scenario, fictional example
Fictional example: booking app
Shared frame: Improvements over the same quarter; Reach in people and Effort in person-months.
- Simplify booking: 1,200 × 2 × 0.8 / 4 = 480.
- Add reminders: 600 × 3 × 0.5 / 2 = 450.
Uncertainty: Six rather than four person-months reduces the first score to 320. Resolve this effort range before making a firm commitment.
Decision: The ordering informs discussion. Dependencies and mandatory commitments receive a separate documented rationale.
