A team is investigating ways to reduce power outages. They determine that an outage can occur in only three ways: grid failure, local transformer failure or local overload. They then investigate each of these three events for possible causes, etc. They draw a diagram that “fans out” using the power outage as the handle of the fan. These improvements are best described by which approach to problem solving?

SCENARIO
A Six Sigma team is measuring the moisture content of corn starch as it leaves the conveyer belt of a
dryer. They collect one sample four cups of starch at times indicated in the chart at fixed locations
labeled A, B, C, and D across the end of the belt. See the diagram below.
The data for a nine hour period are:
Which type of variation dominates? (Hint: Plot the points on the graph above.)
