Literature Review Title: Software Testing Process Models Benefits&Drawbacks: a Systematic Literature Review 
Chapter Title:  Meta-measurement approach 
1. Abstract of Cited Paper (BIB001):  As one of the most challenging and costly processes, the software testing provides strong support for the high quality software. The popular process improvement models do not adequately address testing application issues, nor has the knowledge management (KM) implementation in testing been well defined. The plan-do-check-action (PDCA)-based testing improvement framework is proposed to address these issues. The framework contains the adaptive processes definition, the processes implementation and measurement analysis, and benchmarking-based assessment approach. Experiments show that: the framework can stimulate team member's subjective initiative, promote the software testing process and improve the testing service quality.

Literature Review:
The Meta-measurement model [TM11] was developed to specify and evaluate quality aspects of the test process. The evaluation process is derived from the Evaluation Theory, which defines six elements: target, evaluation criteria, reference standard, assessment techniques, synthesis techniques and evaluation process. All of these elements were applied in the Meta-measurement approach BIB001 . 4.1.12 Plan-Do-Check-Action (PDCA)-based software testing improvement model The PDCA-based software testing improvement model [TM12] provides processes to improve service quality and performance for third party testing centers. It focuses mainly on knowledge management (KM) and balance of processes standardization and flexibility. The framework consists of the following phases: building a learning organization through KM, preparing a process-oriented plan, implementing the plan and collecting data, and continuous improvement BIB002 .
