Conducting performance assessment during the early phases of system development enhances early design decisions of system design. The generated performance models from system design will help in identifying the potential performance problems in the system design based on the result of the performance assessment. In recent years, several methods for performance assessment and modeling have been proposed. This paper presents the comparative evaluation of performance assessment and modeling methods to discover the strengths and weaknesses of the existing methods based on a set of criteria which includes process and modeling elements that was developed with the purpose to represent a specific process to assess the performance attributes with the help of modeling concepts. The four selected methods were evaluated based on these criterions and the results will hopefully guidance for developers to propose better methods for performance assessment and modeling in the future.
