Because software, unlike a major civil engineering construction project, is often easy and cheap to change after it has been constructed, a piece of custom software that fails to deliver on its objectives may sometimes be modified over time in such a way that it later succeeds—and/or business processes or end-user mindsets may change to accommodate the software.
Tools are often used to track bugs and other issues with software. Typically, different tools are used by the software development team to track their workload than by customer service to track user feedback. [17] A tracked item is often called bug, defect, ticket, issue, feature, or for agile software development, story or epic.
Radiation therapy planning software RTP/2 created by Multidata Systems International could incorrectly double the dosage of radiation depending on how the technician entered data into the machine. At least eight patients died, while another 20 received overdoses likely to cause significant health problems (November 2000). [18]
In aspect-oriented software development, cross-cutting concerns are aspects of a program that affect several modules, without the possibility of being encapsulated in any of them. These concerns often cannot be cleanly decomposed from the rest of the system in both the design and implementation, and can result in either scattering ( code ...
"Increasing Complexity" is another key law that underscores the need for active management of complexity, particularly in large and long-lived software projects. [4] As software systems grow, modern engineering practices such as modular design, microservices, and DevOps help control and reduce complexity, ensuring that software remains ...
As the software gets older it becomes less well-suited to its purpose and will eventually stop functioning as it should. Rebooting or reinstalling the software can act as a short-term fix. [1] A proactive fault management method to deal with the software aging incident is software rejuvenation. This method can be classified as an environment ...
Software maintenance is the modification of software after delivery. [1]As per the IEEE standard glossary of software engineering terminology, software maintenance refers to the process of modifying and updating software after its initial development and deployment, to correct faults, improve performance or other attributes, add new features to meet evolving user requirements, or adapt to a ...
Application performance management: the discipline within systems management that focuses on monitoring and managing the performance and availability of software applications. APM looks at workflow and related IT tools deployed to detect, diagnose , remedy, and report on application performance issues to ensure that application performance ...
