One of the researchers is a Thai national with many years industry experience in
information technology.
Personal contacts were used to identify Thai organisations that had implemented EIS for at least one year.
Four organisations were identified and formal approaches were made to the chief
executive officers; all agreed to take part in the research.
The four cases are thought to representative of EIS in Thailand especially given
the early stage of information technology adoption in the country.
The Thai researcher performed field data collection during January and February 1995.
