and the advantages and disadvantages of the mind map and its closest competitor in
the Six Sigma toolbox in the context of how they can be used in the measure phase of
the DMAIC Six Sigma Methodology. Finally, recommendations will be given on how
mind maps can be integrated into the Six Sigma methodology, including the design
for Six Sigma arena.

7.2 THE MIND MAP STEP BY STEP

The mind map can be created by the following steps. Throughout the whole map, the
use of colours and images is highly recommended as these will stimulate the use of
the right-hand side of the brain to enhance memory and creativity. A simple example
of planning a public speech will be used to illustrate the creation of the mind map.

1. Create the central idea (in word or image) in the centre of the page. The central
idea should illustrate clearly what the topic is all about (see Figure 7.1). Make sure
the central word or image is big enough (approximately 2 square inches for a A4
paper size).
2. Add main branch to the central idea. The main branch is a curved line radiating
out from and touching the central image, thicker towards the central image and
thinner away from it. This actually simulates how ideas are radiated out from the
brain.
3. Add a word on the main branch. The main branch should have a word or image
“sitting’’ on the branch to represent one of the main ideas about the topic. The
original recommendation was strictly one word per branch. The word should be in
capital letters, and follow the curvature of the branch (see Figure 7.2). Today, many
Six Sigma practitioners find that a little flexibility and slight bending of the rules
actually make creating the mind map much easier without affecting its abilility
to fulfill its purpose. For example, short phrases also work well. While a single
word may help in memorizing the map, a short phrase actually has the advantage
