A package includes the package logic and other metadata that relates to how the package executes when running. For example, changing an EXE file in the product may require the ProductCode or ProductVersion to be changed for the release management. However, merely changing or adding a launch condition (with the product remaining exactly the same ...
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.
In engineering and systems theory, redundancy is the intentional duplication of critical components or functions of a system with the goal of increasing reliability of the system, usually in the form of a backup or fail-safe, or to improve actual system performance, such as in the case of GNSS receivers, or multi-threaded computer processing.
In the early 1970s, companies began to separate out software maintenance with its own team of engineers to free up software development teams from support tasks. [1] In 1972, R. G. Canning published "The Maintenance 'Iceberg '", in which he contended that software maintenance was an extension of software development with an additional input: the existing system. [1]
Maintenance mode often transitions to abandonware. In the world of software maintenance , it refers to the operational mode a device or service may enter when it is being maintained. For example, while diagnosing, reconfiguring, repairing, upgrading or testing it may be necessary for the device or service to drop to maintenance mode until its ...
For example, three identical systems starting to function properly at time 0 are working until all of them fail. The first system fails after 100 hours, the second after 120 hours and the third after 130 hours. The MTBF of the systems is the average of the three failure times, which is 116.667 hours.
Fixes that fail is a system archetype that in system dynamics is used to describe and analyze a situation, where a fix effective in the short-term creates side effects for the long-term behaviour of the system and may result in the need of even more fixes. [1] This archetype may be also known as fixes that backfire [2] or corrective actions ...
An intelligent maintenance system is a system that uses data analysis and decision support tools to predict and prevent the potential failure of machines. The recent advancement in information technology , computers, and electronics have facilitated the design and implementation of such systems.
