I chose this DRSL because I feel what I learned in engineering class is similar to what I do in my job. In engineering class we had to do engineering documentations before we actually build a project, also they are telling and showing how you are going to do a project and the changes that were made. First is the specification, this is usually about a paragraph or two telling the reader what the project assignment is.
Now what we do at work is very similar. First before a job we get a description and also have a meeting about the job. Then we have our materials list on what we need.
