There are many, many analysis tools. The intent of this course is to focus on several which are more specific to an 8-D problem solving task:
•Information Database
•Decision Making Work Sheet
•Is / Is Not

You will find that the many other analysis tools, and solution tools, will be important, nay invaluable, however the applicability of any one tool will depend upon the specific problem being analyzed as well as the available expertise. For example, not all companies have an employee who is versed in Design of Experiments or FMEAs.
Unfortunately, it is well beyond the scope of this course to attempt to train all of these methodologies.
