Essay On Quality In Software Industry

1.1. SOFTWARE QUALITY

Quality plays very important role in software industry because the objective of software industry is to produce good quality software with in time and budget. So, here quality is nothing but the user’s satisfaction about product, suitable for the target & you can say confirmation of requirements. In broad sense user views of quality must deal with installation, Operational efficiency and convenience. In Software’s, Quality is commonly recognizes as “Lack of bugs” in the Program. There are several definitions [1, 2, 3, 4] for ―”software Quality” term, for examples,

• It is defined by the IEEE [1990] as “the degree to which a system, component or process meets specified requirements and customer (user) needs (expectations)”.

• Pressman [2004] defines it as “conformance to explicitly stated functional and performance requirements, explicitly documented development standards, and implicit characteristics that are expected of all professionally developed software”.

• The ISO, by contrast, defines ―”quality” in [ISO, 1999] as “the totality of characteristics of an entity that bear on its ability to satisfy stated and implied needs”. And

• Petrasch [1999] defines it as “the existence of characteristics of a product which can be assigned to requirements.”

As we have discussed above several definitions of quality that is totally based on the number of quality characteristics and these characteristics could be used to reflect the quality of software product or in other words we can say that quality can be measured by many characteristics or attributes but when we talk about the group of attributes, it is required to be defined that are appropriate for software and group of these attribute are responsible for defini...

...o build a quality model to determine the quality of object oriented systems through the help of their design and internal attributes. It is also evaluate system by analyzing the impact of design patterns, antipatterns and code identify on different software quality characteristics.

1.2.14. ASPECT ORIENTED SOFTWARE QUALITY MODEL: Aspect Oriented Software Quality Model (AOSQUAMO) proposed by Kumar et.al. [3, 28] (2009), it is an expansion of ISO-9126(2001) software quality model. They introduced new four sub-characteristics i.e. modularity, reusability, complexity and code-reusability in the main characteristics (maintainability, efficiency, usability and functionality).

Here on the basis of above discussion of various models we find that all of the above models are based on some characteristics which is generally difficult to understanding the meaning of its term.
