# Read dependency concentration

Identify shared vendors and exposed activities.

> **Access:** member. **Beta** feature, subject to enabled modules and your plan.

## Purpose

Concentration helps examine dependencies shared by multiple activities. It complements the map without replacing review of source data.

## Perform the review

1. Open **Steering → Concentration view**.
2. Check the offered scope and filters.
3. Find vendors and subjects used by multiple activities.
4. Open linked items to understand criticality and documented fallback options.
5. Identify dependencies to discuss with business owners.

## Interpret results

High concentration is a signal to investigate, not an automatic decision. Check actual alternatives, replacement constraints and risks already tracked. An activity without recorded links should not be treated as dependency-free.

## Expected outcome

You have a list of dependencies and affected activities to examine in committee. Record decisions in [risks](https://docs.cisapp.eu/en/risks/register) or [projects](https://docs.cisapp.eu/en/collaboration/projects).

If the view seems inconsistent, start by checking the [dependency map](https://docs.cisapp.eu/en/reporting/dependencies) and activity records.
