Dependency Mapping Skill

Systematic identification and management of cross-project dependencies.

Purpose

This skill provides a framework for:

• Dependency identification
• Dependency classification
• Impact analysis
• Critical path identification
• Dependency tracking and management

Prerequisites

Before dependency mapping, ensure:

Dependency Types

Internal Dependencies

External Dependencies

Dependency Mapping Gates

Gate 1: Dependency Identification

Objective: Identify all dependencies across portfolio

Actions:

1. Review project schedules for cross-project links
2. Interview project managers
3. Document deliverable handoffs
4. Identify external dependencies

Identification Questions:

• What does this project need from other projects?
• What does this project provide to other projects?
• What external inputs are needed?
• What must be complete before this can start?

Output: docs/pmo/{date}/dependency-inventory.md

Gate 2: Dependency Classification

Objective: Classify dependencies by type and criticality

Actions:

1. Classify by dependency type (FS, SS, FF, SF)
2. Classify by source (internal/external)
3. Assess criticality (critical path/slack)
4. Document constraints and assumptions

Criticality Assessment:

Output: docs/pmo/{date}/dependency-classification.md

Gate 3: Impact Analysis

Objective: Understand impact of dependency failure

Actions:

1. Analyze schedule impact
2. Analyze cost impact
3. Identify cascade effects
4. Document mitigation options

Impact Assessment Template:

Output: docs/pmo/{date}/dependency-impact.md

Gate 4: Critical Path Analysis

Objective: Identify and protect the critical path

Actions:

1. Map critical path across projects
2. Identify dependencies on critical path
3. Analyze buffer/slack
4. Recommend protection measures

Critical Path Visualization:

Project A: [Task A1] → [Task A2] → [Deliverable A]
                                          ↓
Project B:                        [Task B1] → [Task B2] → [Deliverable B]
                                                                  ↓
Project C:                                               [Task C1] → [Task C2] → [Final]

Protection Measures:

• Buffer allocation
• Parallel path development
• Early warning triggers
• Contingency plans

Output: docs/pmo/{date}/critical-path-analysis.md

Gate 5: Dependency Tracking Plan

Objective: Create ongoing tracking and management plan

Actions:

1. Define tracking frequency per criticality
2. Assign dependency owners
3. Create communication plan
4. Define escalation triggers

Tracking Template:

Escalation Triggers:

• Critical dependency at risk
• External dependency delayed
• Cascade impact identified
• Owner not responding

Output: docs/pmo/{date}/dependency-tracking-plan.md

Anti-Rationalization Table

See shared-patterns/anti-rationalization.md for universal anti-rationalizations.

Dependency-Specific Anti-Rationalizations

Pressure Resistance

See shared-patterns/pressure-resistance.md for universal pressure scenarios.

Dependency-Specific Pressures

Blocker Criteria - STOP and Report

ALWAYS pause and report blocker for:

Cannot Be Overridden

The following requirements are NON-NEGOTIABLE:

If user insists on violating these:

1. Escalate to orchestrator
2. Do NOT proceed with incomplete mapping
3. Document the request and your refusal

Severity Calibration

When assessing dependency risks:

Track all severities. Actively manage CRITICAL and HIGH.

When Dependency Mapping Is Not Needed

MUST: Full dependency mapping REQUIRED for the following conditions:

MUST: When in doubt, update the dependency map. Stale dependency information causes crisis.
