Perot Systems provided information technology services in the industries of health care, government, manufacturing, banking, insurance and others.

Perot Systems was especially strong in health care industries with services such as digitizing and automating medical records.

The company maintained offices in more than 25 countries around the world, including the United States, Europe, India, China, and Mexico.

Non-official sources stated the merger to Dell failed due continued conflicts in culture, and the loss of talent to various clients such as Tenet Hospitals and other start ups by former leaders.

Additionally, former Perot/Dell employees founded Guide IT in 2013 (Scott Barnes, Jack Evans, John Furniss, Tim Morris, and Russell Freeman, later to include Chuck Lyles) with backing from Ross Perot Jr.[7] As a top-five finisher for the third consecutive year, Perot Systems was named to the Fortune magazine “Most Admired Companies in America” list for IT Services in 2008.
