This section introduces basic operations used in the ISHIKAWA environment and defines terms used to describe the ISHIKAWA procedure. Some details depend on your host, which is the specific system of computing hardware and software you use. For example, all hosts present the ISHIKAWA environment in a system of windows on the host’s display, but the appearance of your windows may differ from the figures in this book. You can find more information in the SAS companion for your host and in your host system documentation.
