good software engineer
The same qualities a good tester has
are useful for a QA engineer. Additionally,
they must be able to understand the entire
software development process and how it can
fit into the business approach and goals of
the organization. Communication skills and
the ability to understand various sides of
issues are important. In organizations in
the early stages of implementing QA processes,
patience and diplomacy are especially needed.
An ability to find problems as well as to see
'what's missing' is important for inspections and reviews.
