Measuring testing efficiency & effectiveness for software upgradation and its impact on CBP

The aim of any company is to deliver reliable product in dynamic and competitive environment. Measuring Testing efficiency and effectiveness is done by proper identification of test attributes and defect origin at various levels of software development phase and removal of these errors becoming an important influencing factor for the invention of quality software. This paper provides an experimental investigation for testing efficiency & effectiveness for software upgradation through numeric example and demonstrates its impact on overall software upgradations as well as on cost, penalty & benefit. The aim of this study is threefold i) To examine the origin of defects and detection during testing phase.(late testing) ii) To investigate proper product release time (early testing)for measuring efficiency and effectiveness and its consequences on overall software upgradation iii) Impact on relative cost, penalty and benefit of a software during its development phase by identifying injected defects and possible magnitudes if they remain untraced and debugged at the final phase before releasing the product.
