Software quality assurance functions

SQA is beneficial for better reliability. SQA is beneficial in the condition of no maintenance for a long time. High quality commercial software increase market share of company. Improving the process of creating software.

Improves the quality of the software. Disadvantage of SQA: There are a number of disadvantages of quality assurance. Some of them include adding more resources, employing more workers to help maintain quality and so much more.

Software Quality Assurance Plan SQAP consists of those procedures, techniques and tools used to ensure that a product meets the requirements specified in the software requirements specification.

The tool essentially performs four kinds of statistical analyses. They are Simple Linear regression, correlation, hypothesis test and Chi square test. The scope of this document is to describe all the software processes and documents used for the quality assurance of the statistical analysis tool.

This plan. The portions of software life cycle covered by this plan are:. IEEE guide for software quality assurance planning Pressman, Roger S.

The statistical tool is an individual project and hence there is only one member involved. The project has to be supervised by a graduate. The committee consists of :. Daniel Andresen. William J. Compliance: is the software in compliance with the necessary laws and guidelines?

Security: Is the software able to handle data related transaction securely? Reliability: this refers to the capability of software to perform under certain conditions for a defined duration. This also defines the ability of the system to withstand component failure.

Usability: refers to the ease of use of a function. Understandability: how easily the functions can be understood Learn ability: How much effort the users of different level need to put in to understand the functions. Efficiency: generally depends on good architecture and coding practices followed while developing software. Maintainability: also known as supportability. It is greatly dependant on code readability and complexity and refers to the ability to identify and fix a fault in a software: Analyzability: identification of the main cause of failure.

Changeability: defines the effort that goes in modification of code to remove a fault. Stability: how stable a system is in its performance when there are changes made to it Testability: how much effort goes in testing the system.

Portability: Ability of the system to adopt to changes in its environment Adaptability: how easily a system adapts to the changes made in specifications Installability: how easily a system can be installed.

Conformance: this is same as compliance in functionality. Replaceability: how easy it is to replace a component of the system in a given environment. Cost of Software Quality Cost of quality is important because when you decide to conduct software testing for your product you are actually going to invest your time, money and effort in getting quality checks done.

By conducting an analysis of cost of software quality you would know what the return on that investment ROI is. Cost of Software Quality. People often get confused between the two but there is a huge difference. While quality assurance is all about preventive activities, quality control focuses on corrective processes. Here is what you need to understand: software testing is a subset of quality control and quality control is a subset of quality assurance.

Theentire focus of Quality assurance is on implementation of processes and procedures that are required for the verification of the software under development and the requirements of the client.

Quality control on the other hand deals with actual activities that ensure that the product is being developed as per the defined requirements. It deals with all the actions that are important to control and verify certain characteristics of the product including testing. Examination and testing of the products is the most important aspect of quality control.
