What are maintainability requirements?
Maintainability defines the time required for a solution or its component to be fixed, changed to increase performance or other qualities, or adapted to a changing environment. Like reliability, it can be expressed as a probability of repair during some time.
What is portability requirements in software engineering?
Portability. DEFINITION: Portability is the ease with which a software system can be transferred from its current hardware or software environment to another environment. ELICITATION: Portability requirements address the user concern for how easy it is to transport the system.
Is portability a functional requirement?
Informally these are sometimes called the “ilities”, from attributes like stability and portability. Qualities—that is non-functional requirements—can be divided into two main categories: Execution qualities, such as safety, security and usability, which are observable during operation (at run time).
What are the performance requirements?
Performance requirements define how well the software system accomplishes certain functions under specific conditions. Examples include the software’s speed of response, throughput, execution time and storage capacity. The service levels comprising performance requirements are often based on supporting end-user tasks.
Is maintainability a functional requirement?
This impact makes maintainability an important non-functional requirement to consider when developing software.
What is maintainability in non-functional requirements?
Maintainability is the ability of the application to go through changes with a fair degree of effortlessness. This attribute is the flexibility with which the application can be modified, for fixing issues, or to add new functionality with a degree of ease.
How do you ensure portability?
Strategies for Portability
- Transferring installed program files to another computer of basically the same architecture.
- Reinstalling a program from distribution files on another computer of basically the same architecture.
What is the key requirement for portability?
The prerequirement for portability is the generalized abstraction between the application logic and system interfaces. When software with the same functionality is produced for several computing platforms, portability is the key issue for development cost reduction.
