Quality - With respect to IT we can say “deliverables 
working as it suppose to be for the customers in the first 
time after installation with no errors”. Usually Quality is 
maintained in a company by group called "SQA Group". They 
are responsible to define and structure the company 
process. It will have member from HR, Finance, Facility, 
Security, Reception, Development, Testing teams. 

Ex: SQA team might decide how the offer letter format of a 
company should look like? How the pay slip format should 
look like? Where the developers should check in the code? 
What kind of templates should be used to develop project 
plan and test plan? 

The belief is following a quality process, the output (that 
is the software deliverables) will also be in high quality. 
That is where SQA comes in the picture.


Where as testing is “executing an application with the 
intention to find bug(s)”. It’s a team not a group like SQA.
