How to mprove workflow speed ?

How to mprove workflow speed ?

Hey Guys , good day :D 

For the past few days i have really been thinking about , workflow and currently i do the kind of work , thats basically vanilla HTML , CSS and JS/jQuery , and needs to be delivered in a timeline , so that really got me thinking of "WHat could i do to increase my workflow speed" . Now a few things that come to my mind are:

- grunt.js (i've just started using this)
- bower (heard good things about it .. but not it using it).
- A processor (SCSS/SASS/LESS) .
- A CSS framework.
- polymer/Angular.js (Do there really help ? )

What Else ? can anybody make a sggestion ? about preprocessors , i really don't know if it actually increase ir decrease workflow speed , so if somebody uses's one here , feel free to extend on that.  Also does anybody use bower here ? . 

i am not asking for readical soulutions but it can be something very minute,eg. i recently realized that know the pull potential of your editor itself can make you a lot more productive(custom snippets , auto completions , these are the basic things , but alot more .... ). 

I would be really grateful if somebody could share their experience and post an elaborate answer. 

P.S. Please keep in mind the question is about Speeding up workflow :D

lastly , sorry for asking a non-jQuery related question :D :D
