This great screencast created and recorded by Chris Coyier will help you understand more when it comes to creating workflow as a web designer. You will know about some very easy to do tricks that will make your life much easier when doing web design tasks. First of all Chris will show you few slides that will show the first steps that should be taken while working on the project. The first slide will highlight the Game flow, which means you will be able to learn what we should actually do at the beginning of the process, after all, we need to start at some point right?
The second step is to actually sort your local environment, which means you should know where you will work from now on. The third step is to understand that working as a team is easier (however you can do it all on your own, no problem). Then the next step is to actually preprocess and finally evaluate your performance (because it is part of the workflow) and then test.
