MoSCoW Prioritization Skill
This skill applies the MoSCoW method to systematically categorize requirements, helping teams focus on what's truly essential.
Theoretical Foundation
Origin
MoSCoW was developed by Dai Clegg at Oracle in 1994 as part of the Dynamic Systems Development Method (DSDM). The name is an acronym for the four priority categories.
The Four Categories
| Category | Meaning | Criteria |
|---|---|---|
| Must Have | Critical–no viable product without | Non-negotiable |
| Should Have | Important but not vital | High value, not critical |
| Could Have | Desirable if time permits | Nice to have |
| Won't Have | Explicitly excluded (this time) | Out of scope |
Key Principle
At most 60% of effort should go to Must Haves, ensuring buffer for the unexpected.
When to Use
- Release planning
- Scope negotiation
- Stakeholder alignment
- Resource allocation
- MVP definition
Instructions
Step 1: Gather All Requirements
List all features/requirements from:
- PRD
- Backlog
- Stakeholder requests
- User feedback
Step 2: Define "Must Have" Criteria
Clarify with stakeholders:
- What makes something absolutely critical?
- What cannot be compromised?
- What breaks the product if missing?
Step 3: Categorize Each Item
For each requirement:
- Must: Would the product fail without this?
- Should: Is it very important but survivable without?
- Could: Is it nice to have if time permits?
- Won't: Should we explicitly exclude this?
Step 4: Validate Must Haves
Challenge each "Must Have":
- Is this truly essential?
- What would happen without it?
- Could we ship and add later?
Step 5: Check 60% Rule
Calculate effort distribution:
- Must Haves: ≤60% of effort
- If over: Re-evaluate what's truly "Must"
Step 6: Document and Communicate

Format:
## Must Have
- [Requirement]: [Rationale]
## Should Have
- [Requirement]: [Rationale]
## Could Have
- [Requirement]: [Rationale]
## Won't Have (This Release)
- [Requirement]: [Why excluded]
