Software Design Review Methods for Object-Oriented Systems

Abstract

Software design review methods are important for improving the quality, maintainability, and reliability of object-oriented systems before coding and deployment activities progress too far. In large software projects, object-oriented design may suffer from weak class responsibility allocation, excessive coupling, poor cohesion, inheritance misuse, unclear interfaces, duplicated behavior, and violation of design principles. This article discusses how structured design review methods help identify architectural and logical weaknesses at an early stage. It explains the role of class diagrams, sequence diagrams, interface specifications, design patterns, dependency checks, responsibility analysis, and object interaction review in evaluating design correctness. The article also highlights common review challenges such as incomplete design documentation, over-complex class structures, unclear abstraction levels, and poor alignment between requirements and design models. A structured object-oriented design review approach is presented to support better modularity, reusability, testability, and long-term software maintenance. The study concludes that systematic design review improves design consistency, reduces downstream defects, and strengthens the overall quality of object-oriented software systems.
