Roger Draper, supervisor of Vyvx,
EIT, and business systems testing, notes, "This mission statement
highlights the foundation of SIT's test approach of having a process

the success of the product being tested. The first major step for software
development success is a defined, repeatable process."
The author comments on the burn-out factors that many testers experience and offers some suggestions for maintaining perspective and managing expectations to help avoid some of the factors that contribute to "testing fatigue".

cases, you'd like to e-mail a web browser shortcut which will "Fetch"
a document from Livelink instead of having Livelink "translate"
the document and display it as an HTML document. Unfortunately, you
can't Copy Shortcut directly. Here's a workaround: "Fetch"
the document onto your local machine normally from Livelink (select
Fetch from the dropdown list for the document). After the document
has been opened properly in the native application, click on
History in the web browser. Under
Today in the History window, click on
livelink. Find the appropriate link in the list of shortcuts
under livelink. The link will contain
func=doc.Fetch in the URL. Right-click on the link and choose
Properties from the context menu. In the properties window,
right-click on the highlighted Internet Address and choose
Copy. The shortcut can now be copied into a document or e-mail
message to create a hyperlink. Likewise, the shortcut can be dragged
from the History window into a document or e-mail message.
