# 4.4 Experience-based Test Techniques

When applying experience-based test techniques, the test cases are derived from the tester’s skill and intuition, and their experience with similar applications and technologies. These techniques can be helpful in identifying tests that were not easily identified by other more systematic techniques. Depending on the tester’s approach and experience, these techniques may achieve widely varying degrees of coverage and effectiveness. Coverage can be difficult to assess and may not be measurable with these techniques. 

Commonly used experience-based techniques are discussed in the following sections.
