# Workflow: Overview

## What are Workflows?

Workflows empower developers to monitor mobile app activity with precision. They enable instant toggling of observability and targeted selection of data for ingestion, from a single client to millions of devices. Deploying a workflow takes seconds, freeing you from the lengthy mobile release cycles that typically take weeks or months.

## Use Cases

Workflows prove invaluable in many scenarios:

- **Issue Investigation:** Toggle detailed granular instrumentation for specific clients during short-lived periods to diagnose ongoing problems.
- **Release Health Monitoring:** Configure rules to augment data collection during app version rollouts.
- **A/B Test Analysis:** Contrast user behavior and app performance between different groups during experiments. 
- **Error and Performance Monitoring:** Create long-lived monitoring to catch elusive errors and edge cases.
- **User Journey Analysis:** Track and understand user flows at each stage.

## Core Concepts

- **Steps:** The building blocks of workflows. Each step in a workflow defines matching rules. As your application emits logs, the Capture SDK attempts to match those logs against the rules in a step.
- **Actions:** Optional behaviors that can be attached to steps, such as _Plot chart_ or _Capture session_. When a log matches the rules in a step, the attached actions are triggered. 
- **Flows:** A series of one or more connected steps. The Capture SDK evaluates the steps in a flow sequentailly. When a match is made the SDK evaluates subsequent logs against the next step in the flow, and so on until every step has been matched and the flow completes.
- **Workflows:** Group together one or more related flows that are evaluated in parallel and can share actions. You might for example create two flows that generate a numerator and a denominator for calculating a rate. 
- **Reset Executions**: A special type of step that resets a flow when a log matches its matching rules.
- **Built-in Events:** A set of logs that the SDK automatically tracks, including app and device states.
- **Exploration:** A container that groups a collection of workflows.
