Software maintenance is the modification of software after delivery. Software maintenance is often considered lower skilled and less rewarding than new development. As such, it is a common target for outsourcing or offshoring. Usually, the team developing the software is different from those who will be maintaining it.
Software evolution is not likely to be Darwinian, Lamarckian or Baldwinian, but an important phenomenon on its own. Given the increasing dependence on software at all levels of society and economy, the successful evolution of software is becoming increasingly critical. This is an important topic of research that hasn't received much attention.
In telecommunications and several other engineering fields, the term maintainability has the following meanings: . A characteristic of design and installation, expressed as the probability that an item will be retained in or restored to a specified condition within a given period of time, when the maintenance is performed by prescribed procedures and resources.
This has important implications for the authenticity, reliability, and trustworthiness of records. Much research is being conducted on the management of digital records. The International Research on Permanent Authentic Records in Electronic Systems (InterPARES) Project is one example of such an initiative.
Important data stored on computers may be copied and archived securely so that, in the event of failure, the data and systems may be reconstructed. When major maintenance such as patching is performed, a backup is recommended as the first step in case the update fails and reversion is required.
The key factor as to when and why this work is being done is timing, and involves a service, resource or facility being unavailable. [18] [19] By contrast, condition-based maintenance is not directly based on equipment age. Planned maintenance is preplanned, and can be date-based, based on equipment running hours, or on distance travelled.
Artistic research, also seen as 'practice-based research', can take form when creative works are considered both the research and the object of research itself. It is the debatable body of thought which offers an alternative to purely scientific methods in research in its search for knowledge and truth.
For example, some birth dates are easier for individuals to recall if the date is close to their own birth date or any other dates they deem important, such as anniversary dates. [53] Research has shown that after being encoded, self-reference effect is more effective when it comes to recalling memory than semantic encoding. [54]
