# Native Workflows

## What is a Workflow?

* The individual apps can be easily combined into pipelines, which are on the DNAnexus platform referenced as workflows.
* These apps are linked together by dependencies and can hand off their outputs to other apps as they complete.
* Apps in a workflow will always begin executing as soon as their inputs are satisfied and if possible they will run independently.
* Workflows can be created by clicking on the **Add button** and selecting the **New Workflow**.

This is what it will look like once you select "New Workflow"

## Running and Monitoring a Workflow

### Set Up and Running the Workflow

* Add the apps that you want for the workflow and order them where the dependencies are generated first
* After that, add in the necessary requirements. They are featured below:

* Select Start Analysis
* You will have a "pre-flight" check to make sure everything that is needed is there. Once that is complete, select Start Analysis again and it will start to run.

### Monitoring a Workflow

* You will be redirected once you have started the analysis.
* The monitor has panels to show what is running, how long it took to complete, and the order they were done in.
* You can view the information in order to see the details of the workflow.
