Having a step by step process to follow when starting a new writing project helps to overcome the natural resistance to starting something new and getting underway with the work.
This summary outlines my step by step processes for :
writing a document using multiple sources of information
writing a document based on my own information.
I hope you find some or all of the elements of my process useful to you. However, everyone has a different way of working, so you may prefer to use it as a springboard for observing your own way of working, and creating your own repeatable process.
