Hi Skumar
I'm assuming you're looking at SMWP with the Nodes expanded, hence you can see that they're not running.
On the right hand side of the screen should be an "Executable" button for each item in the node...click on that and it will prompt you with the relevant information to start the process.
There should be nothing else you need to run if this works as intended.
I'd recommend you verify Dev and QA and running for the same required processes.
Regards
