Components of Software Quality Assurance Testing Services
                     Components of Software Quality Assurance 
Testing Services
Software quality assurance testing services on a higher level seems like we are speaking of 
the evaluation of software based on particular characteristics such as functionality, 
performance, adaptability, etc.
Though software quality assurance testing services go ahead of the quality of the software, 
it also includes the quality of the method used to develop, test and deliver the software.
What is Software Quality Assurance?
        
Software Quality Assurance (SQA) consists of the means to assure the quality of the delivered 
software by controlling software engineering techniques and methods. SQA spans across the 
whole software development lifecycle that encompasses requirements management, 
software design, coding, testing, and release management.
The software can be judged for quality based on the following six components:
Functionality
The functionality of the software is the collection of functions that the software gives. The 
software must provide proper functions as per specifications, and these functions must be 
implemented accurately.
The software should have interoperability, which determines how efficiently the software 
interacts with other components of the system. It must be compliant with the laws and 
guidelines. The software should handle data related transactions securely.
Reliability
The reliability of the software is its capacity to perform under particular circumstances for a 
defined duration. It also compromises the ability of the software to withstand failures of its 
components.
Usability
The usability of the software is its efficiency of use. It also refers to how easily a user can 
understand the functions of the software and how much efforts are required by the users to 
understand the functions.
Efficiency
The efficiency of the software is subjected to its architecture and coding methods 
developed during development.
Maintainability
The maintainability of the software is based on code complexity and readability. It also 
applies to the ability to distinguish and fix an error in the software.
The software is examined on the basis of ease of identifying the main cause of failure and 
the ease of modification of code to remove a fault. It should be firm in its performance 
when the changes are made.
Maintainability also depends on its testability which means how much efforts are required 
for testing the system.
Portability
The portability of the software is its capacity to accommodate to the changes in its 
environment. It describes how efficiently a system adapts to any modifications made in the 
specifications.
It also consists of how simple it is to install the software and how easy is it to replace a 
component of the system in a given environment.
Software quality assurance testing services help to assure that the quality of the software is 
in line with the needs of the client. The main aim of SQA experts is on performing the 
required processes and getting the right quality assurance tool that will assist to deliver 
high-quality software.
