Mind Mapping
Map the structure and linkages between your related factors.
A Mind Map is a pictorial method to represent information that radiates from a central node.
To create a Mind Map:
Step 1: Write a concise heading for the overall theme in the center of a sheet of paper.
Step 2: For each major sub-topic start a new major branch from the central theme and label it.
Step 3: Carry on in this way for ever finer sub-branches.
Step 4: It may be appropriate to put an item in more than one place or to cross-link it to several other items.
Step 5: To differentiate items use a variety of fonts, colors, symbols, etc.
