# Concepts

The core ideas behind Flowlity, used across several modules.

This section explains the ideas behind Flowlity. Each concept shows up in several modules and settings pages: understanding it once helps you everywhere in the app. Each page links to the how-to guide that puts it into practice.

### Lists, metrics and alerts

* [**Views and filtering**](/concepts/concepts/views-and-filtering.md): saved filters, columns, sorting and grouping, and how views scope automations. In practice: [Filter, sort and group a list](/everyday-tasks/how-tos/filter-sort-and-group-lists.md) and [Set up and manage views](/everyday-tasks/how-tos/set-up-views.md).
* [**KPIs**](/concepts/concepts/kpis.md): metric columns you add to the Demand and Planning lists. In practice: [Add KPI columns](/everyday-tasks/how-tos/add-kpi-columns.md).
* [**Metrics glossary**](/concepts/concepts/metrics-glossary.md): what MAPE, MAE, FVA, stock coverage, zero stock days and the other metrics mean.
* [**Alerts**](/concepts/concepts/alerts.md): stock, demand and order alerts, and how to find the urgent ones.

### Demand and forecasting

* [**Demand forecasting explained**](/concepts/concepts/demand-forecasting.md): how Flowlity's probabilistic forecast works, confidence ranges and forecast accuracy.
* [**Forecast events and demand adjustments**](/concepts/concepts/forecast-events.md): the event lifecycle, anomaly detection, and how the demand anomaly agent works with your data.
* [**Product similarities**](/concepts/concepts/product-similarities.md): link related products to share demand history, manage replacements and help new products.

### Inventory and supply

* [**Inventory strategies**](/concepts/concepts/inventory-strategies.md): MTS Flowlity AI, My min, Reorder point, Reorder point + AI, MTO and No replenishment, and when to use each.
* [**Safety stock settings**](/concepts/concepts/buffer-policies.md): service levels, the Flowlity Min / Max corridor, and default vs product-level settings.
* [**How Flowlity calculates Stock Min**](/concepts/concepts/stock-min.md): what drives the minimum stock level.
* [**Supplier constraints and order management**](/concepts/concepts/supplier-constraints.md): lead time, MOQ, order multiple, closures, and how they shape orders.

### Collaboration

* [**Comments**](/concepts/concepts/comments.md): one comment thread per product, shared with order line comments.
