As discussed in the section on activities and settings of I/O psychologists in Chapter 1 of your textbook, consulting firms are a major employer of I/O psychologists. Not shown in your textbook is that there has been a migration of I/O psychologists from private companies to consulting over the past few decades (see class notes for Chapter 1).

In this exercise we are going to take a close look at two of the biggest I/O consulting firms, Development Dimensions International, DDI, and Personnel Decisions International, PDI. They represent very well the work most frequently done by I/O psychologists, even those who work as independent consultants for themselves.

1. For background read Chapter 1, Activities and Settings of I/O Psychologists in your textbook.

2. Go to the links page and go to Development Dimensions International, and then Personnel Decisions International.

3. Go to the section that describe the company and the section that describes products.

4. Write a report that compares and contrasts the two firms. Be sure to cover each of the following:

a. History

b. How big is the company, e.g., how many employees?

c. How many offices, and where are they located (i.e., what countries?)

d. List the services provided.

HINT: Be sure and take notes as you go, or download the information for later use.
