Step 4: Document Your Scope Statement (30 minutes)
Create Scope Statement
Write a clear, concise scope statement:
# Scope Statement Template
**Organization**: [Your Company Name]

- [List excluded data types]
**Rationale**: [Explain the business justification for scope boundaries]

Step 5: Validate with Stakeholders (15 minutes)
Review with Key Stakeholders
Present your scope to:
- Leadership: Ensure business alignment

Document Feedback
Record stakeholder input:
# Stakeholder Review Template
**Stakeholder**: [Name/Role]

**Action Required**: [Changes needed]
**Status**: [Open/Closed]
Action: Conduct stakeholder review and document feedback.
Common Scope Definition Mistakes
Too Broad Scope
Problem: Including everything makes compliance unmanageable Solution: Focus on customer-facing systems and critical data
Too Narrow Scope
Problem: Excluding important systems creates gaps Solution: Include all systems that process customer data
Unclear Boundaries
Problem: Vague scope statements create audit issues Solution: Be specific about what's in and out of scope
Missing Rationale
Problem: No justification for scope decisions Solution: Document business reasons for scope boundaries
Scope Examples
Example 1: SaaS Company
Scope: Customer-facing web application and supporting infrastructure In Scope: Web app, database, payment processing, customer support tools Out of Scope: Internal HR systems, marketing tools, development environments
Example 2: Financial Services
Scope: Core banking systems and customer data processing In Scope: Core banking platform, customer portal, payment systems Out of Scope: Employee benefits systems, marketing databases
Example 3: Healthcare Provider
Scope: Patient care systems and protected health information In Scope: EMR system, patient portal, billing systems Out of Scope: Administrative systems, research databases
Next Steps
Once you have defined your scope:
- Get approval: Secure leadership sign-off on scope
- Document controls: Map controls to your scope
- Implement monitoring: Set up scope monitoring processes
- Plan reviews: Schedule regular scope reviews
