The National Institute of Standards and Technology estimates that software bugs cost the U.S. economy $59.5 billion annually. If more comprehensive software testing was performed, a third of these costs could be avoided. The value of software testing is derived from the quality, price and time that are saved by releasing superior products to satisfied customers. Through techniques such as the utilization of knowledgeable and inventive software testers and early identification of defects, a company can decrease the time to market and the cost of quality, while amplifying the end-user satisfaction level. - See more at: http://www.qualitestgroup.com/The-Value-of-Software-Testing#sthash.BJI9tf3b.dpuf

1. Having testers engaged throughout every stage of the project benefits the business in many ways providing a different focus and insight, which allows issues to be addressed early and consequently cheaply!

Results of poor test engagement
Problems found during roll out:
•Delays if issues arise in training and site implementation when users find functionality is missing, wrong or has bugs
•Delays in implementation in the field while problem are investigated and resolved
•independent check on the development life cycle from business case to live operation
•Find issues early to reduce cost
•Reduce risk leakage between phases
•Ensuring adequate entry and exit criteria are set and observed at each stage of development and testing
Problems found in live operation:
•Reputational damage to IT eroding trust and adversely affecting confidence in future work
•Significant additional project or support costs while issues are resolved
•Additional manual work in the business or IT support to implement workarounds
•Disruption to other development projects due to support requests
•Delayed and/or reduced Return on Investment
•Risk of investigation of the issues by auditors and/or regulatory bodies (especially if issues arise in billing or poor treatment of consumers).
•Prevent the costs of risk mitigation slipping to later stage of projects
•Improve the quality of requirements and design
•Assure business/functional requirements are unambiguous, measureable and testable
•Testers can also help review designs (architecture, database structures) and even code
•Be the “glue” across the project. Testers have to engage with a project from start to finish. No- one else gets that detailed end-to-end view or can add value to all activities.
