On-line tutorials and documentation for the SIGMA message service

The highest goal of the SIGMA service has been to successfully make the transfer from the computer science research environment to the working military message processing environment for which it was intended. One of the problems leading to the failure of such technology transfer in the past has been a lack of appreciation for the importance of the way a system is introduced into a working environment, how users are trained in its use, and how it is documented from the users’ point of view. This paper describes Sigma’S approach to these issues.
