Welcome to QualityMeter

Quality meter log QualityMeter is a tool to compute various design quality attributes for object-oriented programs. We adhere to the time-cost-quality triangle to evaluate the time and cost taken to achieve quality

time-cost-quality triangle

The current version of the QualiyMeter (v0.2.0) computes the following eight quality attributes:

  1. Reusability Reflects the presence of object-oriented design characteristics that allow a design to be reapplied to a new problem without significant effort.
  2. Flexibility Charahtersitics that allow the incorporation of changes in a design. The ability of a design to be adapted to provide functionality related capabilities.
  3. Understandability The properties of design enable it to be easily read and comprehended. This directly relates to the complexity of the design structure.
  4. Functionality The responsibilities assigned to the classes of a design, which are made available by the classes through their public interfaces.
  5. Extendibility Refers to the presence and usage of properties in an existing design that incorporates new requirements in the design.
  6. Effectiveness Refers to a design's ability to achieve the desired functionality and behavior using object-oriented design concepts and techniques.
  7. Modularity class-level Describe the quality of the distribution of methods in the object-oriented classes in a given design.
  8. Modularity method-level Describe the quality of the distribution of the object-oriented classes in the packages in a given design.

Quality attributes 1 to 6 are computed based on the QMOOD model proposed by Bansiya and Davis [1]. Modularity is computed with the formula suggested by Leicht and Newman [2].
