Internal Environment Analysis — VRIN Tool
This tool helps you evaluate your organization’s internal strengths and weaknesses across the value chain. Strengths are assessed using the VRIN framework (Valuable, Rare, Inimitable, Non-substitutable) to identify potential core competencies and sources of competitive advantage.
How to Use
Step 1: Enter Organization Information
Add your organization/unit name and select your industry.
Selecting an industry will auto-populate common value chain activities.
Step 2: Review Activities
The tool organizes activities into:
Primary Activities
Support Activities
You may also add custom activities.
Step 3: Add Strengths (VRIN Required)
For each activity:
Enter a strength.
Select a VRIN level (V, VR, VRI, VRIN).
Add notes or evidence (optional).
Only VRIN-rated strengths qualify as core competencies.
Step 4: Add Weaknesses
Record internal gaps or constraints.
Weaknesses do not use VRIN ratings.
Step 5: Generate Summary
Click Generate Summary to view:
Core competencies (VRIN only)
All strengths (with VRIN levels)
All weaknesses

Tip: Be evidence-based when assigning VRIN levels — over-rating strengths reduces strategic clarity.
Internal Environment Analysis
What is VRIN? (used for strengths only)
- V — Valuable but common → typically competitive parity.
- VR — Valuable + Rare but imitable → temporary advantage.
- VRI — Valuable + Rare + Inimitable but substitutable → temporary advantage until substitutes diffuse.
- VRIN — V+R+I+N → more durable advantage.
