Software testing drives value for companies by keeping customers happy, making workers more productive, reducing development and maintenance costs, minimizing infrastructure costs, and adding financial value. Thorough software testing ensures that applications meet quality expectations, improving user experience and reducing the likelihood of customers abandoning products. It also identifies issues early in the development cycle, minimizes the need for costly debugging, reduces the size and cost of IT teams, and optimizes infrastructure spend by identifying areas to improve performance and usability. By investing in software testing, companies can maximize revenue and profitability while minimizing costs, making it a critical component of their overall success.
