Dear Friends,

I want to measure the quality of my web application based Service Oriented Architecture.
There are a standard for webservice quality factor from OASIS :
Web Services Quality Factors Version 1.0:
http://docs.oasis-open.org/wsqm/WS-Quality-Factors/v1.0/cos01/WS-Quality-Factors-v1.0-cos01.pdf

I following the software quality measurement method for :
1. Response Time
Response Time = Client Latency + Network Latency + Server Latency
2.Maximum Throughput
3.Availability
4.Accessibility
5.Successability

My questions are :
1. Do you guys have another way to measure the software quality for web services?
2. I'm develop the web service using visual studio 2010 with WCF, did you guys know a tool for measure the quality of web service?
As I know, there is a tool named "Lab Center" from microsoft visual studio 2010 to testing the software from performance and response time attributte.

God bless you :)
