Workflow

Hi Narayana,

Thanks for reaching out to Adobe Community.

The best way to understand workflows is to go through the AEM topics. This one is really good and has a tutorial:

http://dev.day.com/docs/en/cq/current/workflows/wf-overview.html

Also see:

http://dev.day.com/docs/en/cq/current/workflows/wf-extending.html

Here is a community article that talks about how to create a custom workflow step:

Once you go through these topics -- you will gain a better understanding of workflows. 

Also Please go through the AEM Workflow session conducted by Adobe  on 24th March: https://helpx.adobe.com/experience-manager/using/Workflows.html. 

With this, you will understand more on workflows.

Thanks,
Ratna Kumar.
