The main objective of U-QASAR is to create a flexible Quality Assurance, Control and Measurement Methodology to quantify the quality of the Internet-related software development projects and the resulting products. The methodology will be supported by an Internet solution composed of several knowledge services based on open standards that will be able to self-adapt to fast changes in scope and requirements, so as to provide an accurate measurement of the quality at any time.The U-QASAR Internet Services will monitor the different stages of the software development process, interoperating with the existing applications and systems to provide quantitative information about the quality of each process, the project as a whole and the resulting products. Data obtained in real-time by the U-QASAR monitoring services will be used indistinctively by software engineers, designers, developers, testers and managers alike for different purposes. In that sense software engineers, developers and testers will be able to rapidly correct inadequate trends in design, development and testing, project managers will be able to schedule deliveries with the agreed level of quality and principals will be able to forecast the cost and quality of future projects. This will introduce a high level of automation in the Software Quality Management (SQM) process avoiding the traditional problems of data gathering and analysis in traditional measurement and SQM processes (e.g. Difficulty in demonstrating the completeness, accuracy and integrity of data...). U-QASAR methodology and platform will be assessed in 2 opposed business cases in order to validate the results in different conditions. The first business case will belong to a large software company developing large Internet projects in RUP methodology. The second business case will belong to a SME developing complex projects in Agile methodologies.
