Scatter Gram
is technique reects the result of a relationship between two variables.
e result is plotted on a graph, demonstrating the causal or correlative
relationship between an independent and a dependent variable. To
showthe measure of central tendency, a line is drawn through the middle
of a cluster, indicating the average. While not directly a creativity tool,
itdoes help ag anomalies that provide fruit for creative thinking.
Keep in mind the following when using a scatter gram:
1. Determine a meaningful population. Be sure to make a reasonably
intelligent guess when identifying two variables, preferably one
being an independent variable and the other a dependent variable. It
should be anticipated that the independent and dependent variables
have a relationship. During tests, record the results on the graph.
2. Look at the measure of central tendency and draw a line through the
clustering. en look for anomalies, that is, those considerably below
or above the measure of central tendency. Such anomalies have the
potential to provide insight into new areas.
3. Of course, verify through further testing that a true relationship
exists between the two variables. What may appear as a relationship
may really be due to an unknown third variable.

Some ways to use a scatter gram on a project include:
• Ascertaining if training on a subject has reduced a learning curve
• Determining the impact of a change in cost and schedule baselines
• Identifying the relationship of two variables involved in making a
change to a process
Crawford Slip Technique
is technique is another brainstorming method used to develop creative
ideas to solve a problem. Rather than initially having everyone generate
ideas as a group, the participants, with the aid of a facilitator, rst dene
a problem. Using a well-dened problem statement, each person records
ideas and other supporting thoughts on a slip of paper or note card. Each
description should be clear and concise. en, the slips or cards are com-
piled, grouped, and summarized to reduce the number of categories.
eresults are incorporated in a nal report.
