🧠 What is the RICE Scoring Model?

  

RICE is an acronym that stands for:

Letter	Factor	What it Measures
R	Reach	How many people will be affected by this in a given time period?
I	Impact	How much it will improve or benefit each person (on a scale)?
C	Confidence	How sure are you about your estimates (Reach & Impact)?
E	Effort	How much time, resources, or work will this take (in person-months)?

📊 RICE Score Formula:

$$\text{RICE Score}=\frac{\text{Reach}\times \text{Impact}\times \text{Confidence}\text{<br>}}{}$$

RICE Score=EffortReach×Impact×Confidence / Effort​

A higher RICE score means the idea or task delivers more value with less effort.

📌 Example: Prioritizing Product Features

Feature	Reach	Impact	Confidence	Effort (in weeks)	RICE Score
Add dark mode	1,000	2 (Medium)	80%	2 weeks	800
Improve search function	500	3 (High)	90%	1 week	1,350
Add chatbot	300	1 (Low)	50%	2 weeks	75

✨ Result:

Improve search function is the top priority, even though it reaches fewer users, because it delivers high impact quickly with high confidence.

🔢 Scoring Scales (Recommended)

Impact Scale:

3 = Massive impact
2 = High impact
1 = Medium impact
0.5 = Low impact
0.25 = Minimal impact

Confidence Scale:

100% = High confidence
80% = Medium confidence
50% = Low confidence

Effort is usually measured in "person-months" or "person-weeks" (you can adjust based on team size or task size).

🎯 Why Use RICE?

• Helps prioritize based on value vs. effort
• Brings objectivity to decision-making
• Great for teams with limited resources or time
• Aligns stakeholders on why a feature or idea is important
