# NIST PF CONTROL Function — Implementation Workflows

## Workflow 1: Data Lifecycle Management

### Steps
1. **Define Data Categories**: Classify all personal data categories processed
2. **Map Lifecycle Stages**: Collection, storage, processing, sharing, retention, deletion
3. **Assign Controls**: Map technical controls to each lifecycle stage
4. **Configure Retention**: Implement automated retention schedules per category
5. **Enable Rights**: Configure data subject access, correction, deletion capabilities
6. **Deploy Logging**: Implement audit logging at each lifecycle control point
7. **Test and Validate**: Verify controls function correctly end-to-end

## Workflow 2: De-identification Implementation (CT.PO)

### Steps
1. **Assess Use Case**: Determine data utility requirements
2. **Select Technique**: Choose appropriate de-identification method
3. **Calibrate Parameters**: Set k-anonymity k value, DP epsilon, etc.
4. **Implement**: Apply de-identification to the dataset
5. **Validate**: Test for re-identification risk
6. **Document**: Record methodology and residual risk
7. **Monitor**: Ongoing re-identification risk monitoring

## Workflow 3: Retention Schedule Enforcement

### Steps
1. **Inventory Data Stores**: Identify all locations holding personal data
2. **Map Legal Requirements**: Document retention obligations per jurisdiction
3. **Define Schedules**: Set retention periods per data category
4. **Configure Automation**: Deploy automated purging mechanisms
5. **Handle Exceptions**: Implement legal hold process
6. **Verify Compliance**: Audit data stores against retention schedules
7. **Report**: Generate retention compliance reports
