Disadvantages of Internal Testers:
- Bias: Internal testers may be biased towards the product and overlook potential issues.
- Limited perspectives: Internal testers may lack diverse perspectives and experiences, leading to a narrower testing scope.
- Time constraints: Internal testers may have other responsibilities, impacting testing time and quality.
- Lack of specialized skills: Internal testers may not possess specialized testing skills, such as performance testing or security testing.
Advantages of External Testers:
- Unbiased perspective: External testers provide an objective and unbiased view of the product.
