What is meant by FURPS?
FURPS is an acronym representing a model for classifying software quality attributes (functional and non-functional requirements): Functionality – Capability (Size & Generality of Feature Set), Reusability (Compatibility, Interoperability, Portability), Security (Safety & Exploitability)
Why is FURPS used?
FURPS is an acronym for Functionality, Usability, Reliability, Performance and Supportability of computer systems software, but is now appropriate for the classification of many more associated systems and services (Zimmer 1989).
What does P stands in FURPS quality attributes?
The quality factors described by McCall and his colleagues represent one of a number of suggested “checklists” for software quality. Hewlett-Packard developed a set of software quality factors that has been given the acronym FURPS—functionality, usability, reliability, performance, and supportability.
What are the software quality attributes developed by Hewlett-Packard?
For the Software Quality Metrics the Hewlett-Packard normally follows the five Juran quality parameters namely the functionality,the usability, the reliability, the performance and the serviceability.
What is performance in FURPS?
Performance – Performance involves things such as throughput of information through the system, system response time (which also relates to usability), recovery time, and start-up time.
What is a non-functional requirements in software?
Nonfunctional Requirements (NFRs) define system attributes such as security, reliability, performance, maintainability, scalability, and usability. They serve as constraints or restrictions on the design of the system across the different backlogs.
What factors are used to measure software quality?
Product Operation Software Quality Factors
- Correctness. These requirements deal with the correctness of the output of the software system.
- Reliability. Reliability requirements deal with service failure.
- Efficiency.
- Integrity.
- Usability.
- Maintainability.
- Flexibility.
- Testability.
What is non-functional requirements in software?
What is difference between functional and nonfunctional requirements?
What is the difference between functional and non functional requirements? Functional requirements explain how the system must work, while non functional requirements explain how the system should perform.
What are the types of software metrics?
Types of Software Metrics
- Formal code metrics—Such as Lines of Code (LOC), code complexity, Instruction Path Length, etc.
- Developer productivity metrics—Such as active days, assignment scope, efficiency and code churn.
- Agile process metrics—Such as lead time, cycle time and velocity.
What is difference between functional and non-functional requirements?
What is verification and validation in software?
In software project management, software testing, and software engineering, verification and validation (V&V) is the process of checking that a software system meets specifications and requirements so that it fulfills its intended purpose. It may also be referred to as software quality control.
What is software validation testing?
Software Testing – Validation Testing The process of evaluating software during the development process or at the end of the development process to determine whether it satisfies specified business requirements. Validation Testing ensures that the product actually meets the client’s needs.
