Experience Surveys
• What is being done?
• What has been tried in the past with or without success?
• How have things changed?
• Who is involved in the decisions?
• What problem areas can be seen?
• Whom can we count on to assist or participate in the research?

Exhibit 6-6 Types of Asymmetrical Causal
RelationshipsRelationship Type Nature of Relationship Examples
Stimulus-response An event or change results in a response from some object.
• A change in work rules leads to a higher level of worker output.• A change in government economic policy restricts corporate financial decisions.• A price increase results in fewer unit sales.
Property-disposition An existing property causes a disposition.
• Age and attitudes about saving.• Gender attitudes toward social issues.• Social class and opinions about taxation.
Disposition-behavior A disposition causes a specific behavior.
• Opinions about a brand and its purchase.• Job satisfaction and work output.• Moral values and tax cheating.
Property-behavior An existing property causes a specific behavior.
• Stage of the family life cycle and purchases of furniture.• Social class and family savings patterns.• Age and sports participation.
Definitions: A stimulus is an event or force (e.g., drop in temperature, crash of stock market, product recall, or explosion in factory). A response is a decision or reaction. A property is an enduring characteristic of a subject that does not depend on circumstances for its activation (e.g., age, gender, family status, religious affiliation, ethnic group, or physical condition). A disposition is a tendency to respond in a certain way under certain circumstances (e.g., attitudes, opinions, habits, values, and drives). A behavior is an action (e.g., consumption habits, work performance, interpersonal acts, and other kinds of performance).
