| Abstract | Quality is a major challenge for all complex software systems. Some important attributes of software quality include reliability, availability, safety, security, survivability, performance, accuracy, etc. These have long been requirements of aerospace and defense systems. Now, equally challenging requirements are being placed on "everyday systems" that increasingly provide the infrastructure for our daily lives such as commercial, e-business and embedded systems. They are subject to modest, usually tacit, often stakeholder-specific quality requirements. And it is important that we can define and meet a software system's quality requirements to be fit for its purpose.; However, there are many views of software quality. There also exist many ways to suboptimize its achievement and/or misallocate limited project resources using incomplete views. In addition, complex missions or projects usually involve a heterogeneous group of stakeholders with various (often time-varying) quality priorities and different (often conflicting) needs. This makes both one-size-fits-all quality metrics and software development processes driven by such metrics risky to use. This also points to the need for better frameworks to define, reason about and achieve quality attributes.; Based on these observations, the primary goal of this dissertation is to develop a Value-Based Software Quality Analysis framework that integrates the stakeholder/value approach into quality attribute definitions, metrics, models and development processes aiming at achieving the appropriate quality levels for software systems. This framework pays explicit attention to business values that a software system generates for its success-critical stakeholders. It helps us to understand the nature of quality and to achieve the stakeholder mutually satisfactory quality requirements. It addresses the above problems in four aspects: 1) value-based definitions of software quality attributes; 2) value-based quality metrics; 3) Value-Based Software Quality Model (VBSQM) to reason about the Return On Investment (ROI) of quality and to perform combined risk analyses; and 4) Value-Based Software Quality Achievement (VBSQA) process.; Finally, the VBSQM and VBSQA process have been applied and found to be effective on three diverse software systems with different value profiles: a USC-CSE e-service project, the NASA/USC Inspector SCRover project, and a real-world ERP software development project in industry. |
