Boundary Value Analysis (BVA) enhances software testing for startups and small businesses by focusing on critical input values at the boundaries of valid and invalid input ranges. This method helps identify potential errors and defects that may occur at extreme values, which are often overlooked. By testing the edge cases, BVA ensures more robust software performance, minimizing risks of failures. It is cost-effective and efficient, making it particularly valuable for small businesses with limited resources. Ultimately, BVA leads to higher quality products, better user experiences, and reduced post-launch issues, which is vital for small-scale operations.
