# Quickstart: your first scenario

New installs come seeded with a sample workspace, **Acme Corp**, containing a dozen example scenarios (ransomware, data breach, wire fraud, DDoS, and more). Browse those for inspiration, then build your own.

{% stepper %}
{% step %}

### Create a scenario

Click the **+** button at the top of the left icon rail and choose **New scenario**. Give it a name that describes the loss event, for example "Ransomware outbreak across corporate domain". Optionally set a **Stakeholder**, write up the **Loss event scenario** description, and add **Tags**.
{% endstep %}

{% step %}

### Estimate Loss Event Frequency

The **Loss Event Frequency (LEF)** card asks: how often per year does this loss event actually occur? If you have a feel for it, estimate it directly with a range (for example a PERT distribution with minimum 0.1, most likely 0.5, maximum 2 events per year). If not, decompose it into **Threat Event Frequency x Vulnerability** and estimate those instead.

Use the **Analyst notes** box on the card to record your assumptions and sources.
{% endstep %}

{% step %}

### Estimate Loss Magnitude

The **Loss Magnitude (LM)** card asks: when the event happens, how much does one occurrence cost? Estimate a single distribution, or split it into **Primary Loss** plus **Secondary Risk**, and further into the six FAIR forms of loss if you want that granularity.

A lognormal defined by its 10th and 90th percentiles is a common starting point: "I'd be surprised if it cost less than $200k or more than $5M."
{% endstep %}

{% step %}

### Save and review results

Save the scenario and select it in the scenario table. The simulation runs automatically and the **Results dock** at the bottom fills in:

* Summary tiles: **Expected Annual Loss**, **Median**, **P90**, **95% VaR**, **P99**, and the probability of any loss in a year
* A **Loss Exceedance** curve and **Histogram**
* A **risk rating** (Low, Moderate, High, or Critical) against your risk appetite
  {% endstep %}

{% step %}

### Iterate

Adjust your estimates and watch the results update. Simulations re-run automatically as you change inputs. When your scenario is solid, add it to a [portfolio](/crq-pro/core-concepts/portfolios.md) or generate a [report](/crq-pro/guides/reports.md).

Not ready to finish? **Save draft** parks an incomplete scenario. Drafts are excluded from simulations and reports until you complete them.
