Web service plays a vital role in the service industry to improve the web service applications and it is service oriented architecture. Due to which formation of composite service leads to non-optimal. Service selection task in the composition process is to select the best service for each candidate services out of available services which are a functionally similar but non-functional measures of services are different. This paper, presents the investigation of quality of service parameters and optimality criteria for services selection. The work in the paper provides the analysis of quality of service parameters used in existing works for services selection/composition. Through the survey and analysis it has been revealed that the response time, availability, and reliability are most common used quality of service attributes with minimum/maximum as optimality criteria. However, after analysis of these parameters, the work suggests to use these attributes to solve optimal services selection problem in composition.
