Runbook 01 — Privacy Impact Assessment & Data Subject Request Operations

Field Details
Runbook Type Privacy Operations / GRC
Primary Roles Privacy Analyst, GRC Analyst
Supporting Roles Legal, Security, IT, Data Governance, Procurement, Business Owners
Difficulty Intermediate
Primary Processes PIA/DPIA Operations + Data Subject Requests
Execution Model Event-Driven
Primary Objective Consistent, Evidence-Based Privacy Operations

This runbook provides a repeatable operational process for two of the most important activities in an enterprise privacy program:

01 Privacy Impact Assessment Operations
02 Data Subject Request Operations

The objective is to make privacy work:

Repeatable

Risk-Based
Time-Bound
Evidence-Driven
Auditable

rather than dependent on ad hoc emails, spreadsheets, or individual knowledge.

The runbook covers two connected workflows.

Countries
Data Flows
Retention

Ask the business owner:

What exactly are we trying to achieve with this processing?

Document each purpose separately.

Example:

Customer Email
Account Authentication

and:

Customer Email
Marketing

should not automatically be treated as the same purpose.

For each data field ask:

Why Is It Needed?
What Happens
If We Do Not
Collect It?
Can We Use
Less Data?
Can We Use
Less Precise Data?

9. Identify Prohibited or Unnecessary Data

Section titled “9. Identify Prohibited or Unnecessary Data”

Examples:

Password in AI Prompt
Full Payment Card

Avoid copying one privacy framework’s legal model into another without analysis.

Verify whether the system can:

Find
Access

For each risk determine:

What Control Exists?
Who Owns It?
Is It Designed Well?
Is It Implemented?
What Evidence Exists?

Example:

Mistake 2 — PIA Starts After Development

Section titled “Mistake 2 — PIA Starts After Development”

By then important architectural decisions may already be difficult to change.

Mistake 3 — Privacy Team Owns the Business Risk

Section titled “Mistake 3 — Privacy Team Owns the Business Risk”

Business owners must remain accountable for their processing activities.

Mistake 4 — Vendor Review Stops at Contract

Section titled “Mistake 4 — Vendor Review Stops at Contract”

Technical behavior and processing practices must also be understood.

Mistake 5 — AI Added Without PIA Reassessment

Section titled “Mistake 5 — AI Added Without PIA Reassessment”

AI can materially change the purpose, data flow, vendor relationships, and privacy risk.

Mistake 6 — DSR Deadline Starts When Privacy Notices It

Section titled “Mistake 6 — DSR Deadline Starts When Privacy Notices It”

The request receipt date must be determined according to applicable requirements, not internal convenience.

Personal information usually exists across multiple systems.

Legal retention and legal holds must be considered.

Mistake 9 — Keep Everything as an Exception

Section titled “Mistake 9 — Keep Everything as an Exception”

Exceptions must have a valid documented basis.

Mistake 10 — DSR Response Sent Without QA

Section titled “Mistake 10 — DSR Response Sent Without QA”

One wrong record can turn a privacy-rights response into a data breach.

During PIA operations, a GRC analyst may:

  • track privacy screening.

  • coordinate evidence.

  • maintain PIA registers.

  • support risk assessment.

  • track remediation.

  • verify control evidence.

  • maintain approval records.

  • monitor overdue actions.

  • prepare metrics.

During DSR operations, a GRC analyst may:

  • maintain DSR registers.

  • track deadlines.

  • coordinate system owners.

  • maintain search evidence.

  • coordinate vendor tracking.

  • maintain exception evidence.

  • monitor completion.

  • support QA.

  • report KPIs and KRIs.

For every new project ask:

What Personal Data?
Why?
Do We Need It?
Where Does It Go?
Who Receives It?
How Long?
Which Rights Apply?
What Could Go Wrong?
What Must Be Fixed
Before Launch?
Who Accepts
Residual Risk?

For every privacy request ask:

Who Is Asking?
Which Right?
Which Deadline?
Have We
Verified Them?
Where Is
Their Data?
Which Vendors
Have It?
What Can
We Fulfil?
What Must
Be Retained?
Has QA
Been Completed?
Can We Prove
What We Did?

That is the operational mindset behind repeatable enterprise privacy management.

  • PIAs should be triggered by new or materially changed personal-data processing.

  • Privacy screening determines the appropriate level of assessment.

  • PIA work should happen before production whenever possible.

  • Data purpose, necessity, flows, vendors, retention, rights, and security all form part of privacy-risk assessment.

  • High-risk processing may require enhanced assessment or DPIA depending on applicable requirements.

  • Privacy findings should be converted into tracked remediation actions.

  • Residual risk should receive explicit approval.

  • Material changes should trigger PIA reassessment.

  • Data subject requests require centralized intake, verification, deadline management, discovery, fulfilment, QA, and evidence.

  • Identity verification is essential before disclosing or changing personal information.

  • Enterprise discovery must include cloud, SaaS, vendors, AI, archives, and other applicable repositories.

  • Deletion requests require retention and legal-hold analysis.

  • Access responses require careful protection of third-party information.

  • AI introduces additional privacy-rights challenges involving prompts, vectors, memories, logs, and provider processing.

  • Strong privacy operations depend on evidence, not verbal confirmation.

  • GRC helps make privacy processes measurable, repeatable, traceable, and auditable.

➡️ Next: Runbook 02 — Privacy Incident, Breach & Regulatory Response Management

In the next runbook, you will move from routine privacy operations into managing privacy incidents and personal-data breaches.

You will work through:

Privacy Incident
Detection
Containment
Personal Data Assessment
Affected Individuals
Risk Assessment
Applicable Regulations
Notification Decision
Regulator / Individual Response
Evidence Preservation
Root Cause
Corrective Action
Post-Incident Monitoring

You will build and operate practical artifacts including a Privacy Incident Register, Breach Assessment Matrix, Regulatory Notification Decision Log, Affected Individual Register, Evidence Pack, Root-Cause Analysis, Corrective Action Tracker, and Post-Incident Privacy Review.
