Quality attributes are the overall factors that affect run- time geste, system design, and stoner experience. principally Quality Attributes are representing areas of concern that have the eventuality for operation wide impact across layers and categories.
What’s Quality?
Quality can be define in different manner. In simple word its prosecution grounded on client demand in systems end nothing additional Quality description may differ from person to person. But eventually there should be same norms. Below mentioned following factors are used to measure software development quality. Each trait used to measure the product performance. All attributes cover Quality assurance as well as Quality control. Quality Assurance conditioning are acquainted towards forestallment of preface of blights and Quality control conditioning are aimed at detecting blights in products and services.
Trustability
In trustability our main focus on two factors which are Correctness and Vacuity. Measure if product or operation is dependable enough to tolerate in any complaint. In trustability we concentrate on that operation/ Product should give regularly true results or response to druggies while in running. Product trustability is measured in terms of working of design under different working terrain( window, Mac, Linux) and different conditions( low net speed).
trait Measuring Point( s)
How important your product Software is dependable on different terrain while running?
Maintainability
Maintainability is completely dealing with maintaining of operation performances, builds. Maintainability principally dealing with debugging and for revision and extension of functionality of operation, products, managing of operation performances, Readability, Extensibility and most important Testability of software/ operations.
trait Measuring Point( s)
How important your product Software is justifiable or Extensibility when you going to revision in any section of software?
Usability
In this trait as its name showing the usability of operation is checking or measuring or measures are should measure in terms of ease of use. operation should be stoner friendly. Should be easy to learn. Navigation should be simple. The system must be easy to use for input medication, operation, and interpretation of affair. give harmonious stoner interface norms or conventions with our other constantly used systems. Easy for new or occasional druggies to learn to use the system.
trait Measuring Point( s)
How important your product Software is Usable or easy in use for your target followership?
Portability
In portability we’re dealing and talking about the ease with which a software system can be acclimated to run on computers any other than the bone
for which it was designed. Or in portability is dealing with is a program/ operation designed to run on a compatible computer without being installed leaving the computer’s configuration information complete.
trait Measuring Point( s)
How important your product Software is portal or transmittable for different platforms?
Correctness
In Correctness we’re dealing with operation those aspects which are helping to druggies that operation correctness in terms of its functionality, designs used internally and the navigation should be correct. This means operation should follow to functional conditions.
trait Measuring Point( s)
How important your product Software is correct in working?
Effectiveness
To Major system quality trait. Measured in terms of time needed to complete any task given to the system. For illustration system should use processor capacity, fragment space and memory efficiently. If system is using all the available coffers also stoner will get degraded performance failing the system for effectiveness. If system isn’t effective also it can not be used in real time operations.
trait Measuring Point( s)
How important your product Software is effective in applications or in working from system coffers point of view?
Integrity or security
Integrity always comes with security because System integrity or security should be sufficient to help unauthorized access to system functions, precluding information loss, insure that the software is defended from contagion infection and all unauthorized access on Platform, and guarding the sequestration of data entered into the system.
trait Measuring Point( s)
How important your product Software is Secure and integral in information lost while it’s on customer end or in/ after product?
Testability
System should be easy to test and find blights. If needed should be easy to divide in different modules for testing.
trait Measuring Point( s)
How important your product Software is testable while it’s in testing phase?
Inflexibility
Should be flexible enough to modify at any time if you need. Easy- going to other products with which it needs communication. Should be easy to affiliate with other standard 3rd party factors.
trait Measuring Point( s)
How important your product Software is flexible or probative in revision while it’s in testing phase?
Reusability
In this trait we’re principally checking or measuring only one main factor that’s dealing with reusability of your products, software in another design or development phase for any other systems. It’s veritably salutary that Software exercise is a good cost effective and time saving development way. Different law libraries classes should be general enough to use fluently in different operation modules. Dividing operation into different modules so that modules can be reused across the operation.
trait Measuring Point( s)
How important your product Software is applicable or probative reusability when we need?
Interoperability
In Interoperability testing testers are measuring the factors of operations Software’s affiliated to Interoperability of one system to another should be easy for product to change data or services with other systems. OR Interoperability testing involves testing whether a given software program or technology is compatible.
trait Measuring Point( s)
How important your product Software is Interoperability with other operations or software results?
Applying above quality attributes norms we can determine whether system meets the conditions of quality or not. As specified over all these attributes are applied on QA and QC process so that tester or client also can find quality of operation or system.
