The average cost to fix a defect at the end of the lifecycle is 400-800 times greater than if it were addressed earlier. On average, poor requirement practices account for 60 percent of a project’s time and budget. Organizations with well-defined, closely managed, and effectively measured quality activities succeed and continuously improve. Yet, in a recent survey, 77 percent of managers reported that bad decisions have been made due to a lack of accurate information.
This presentation outlines the TMMi model, the de facto international standard to assess and improve test maturity, featuring independent best practices from more than 14 quality and test models. It explores how TMMI can be used in conjunction with the GQM model to ensure that upper management is provided with the information they need to make informed business decisions.
