You can map out your search strategy in whatever way works for you.
Some people like lists and so plan their search strategy out in a grid-box or table format. Some people are more visual and like to draw their strategy out using a mind-map approach (either on paper or using mind-mapping software). Some people use sticky notes or Trello or a spreadsheet.
If it works for you then as long as it enables you to search systematically and thoroughly there's no need to change the way you work.
If your search strategies are not very developed, the method you use doesn't lead to a good search, then consider using one of the other methods to see if changing your approach helps.
