This is maintenance that will improve the performance of the ICT system. Usually this will involve adding features not originally present to the software to make it produce the information from a database faster or to improve the speed of a network

It is very important to document any maintenance activity. The documentation is proof of the time and type of maintenance performed.
What is IT maintenance?
Its best the manage the highways maintenance...
First it is important to understand first line maintenance. First line maintenance is the maintenance that is performed by the assigned maintenance staff for certain equipment or other asset. These are the people that come in and perform the planned/contracted maintenance. Usually these are standardized activities that are performed on regular intervals. As a part of this maintenance some difficulties may arise, or the status of the assets can be such that additional maintenance activities are needed. When these activities can't be done as part of the regular (first line) maintenance, these activities are replanned and not seldom performed by other, more specialized staff. This is called the second line maintenance. In some cases even third line maintenance exists. This will be the case when the second line maintenance staff can't solve the problem due to for example a design error or the unavailability of spare parts (that became obsolete). In this case the asset should be changed/improved, and this is sometimes called third line maintenance.
Adaptive maintenance is where the programmer modifies existing software to suit new tasks.Perfective maintenance, on the other hand, is where the programmer modifies software to make it perform better.
4 types reactive- response to equipment malfunction preventive- periodic checks predictive- periodic measurements and trending of equipment process prevention- equipment design is based on minimal maintenance requirements
Distinguishing between types of software maintenance can be challenging because many maintenance activities often overlap in their objectives and processes. For instance, corrective maintenance (fixing bugs) may involve modifications that also enhance functionality, blurring the lines with adaptive or perfective maintenance. Additionally, the context of changes may vary, making it hard to classify them strictly into one category. This complexity is further compounded by the continuous evolution of software, where updates often serve multiple maintenance purposes simultaneously.
Karen Elsa Sandness has written: 'The Evolution of the Japanese Past and Perfective Suffixes'
An aorist is a verb in the past tense and aorist aspect - the event described by the verb viewed as a completed whole. It is also known as the perfective past.
Some words that start with the prefix "perf" are perfect, perform, and perfective.
Software Maintenance : is the activity of modifying the software product after delivery ; in order to correct faults, improve performance and to improve other attributes ( attributes of a good software ) .Software maintenance is a vital element in SDLC . Normally and more often done by the developers / or software maintainers ( of the software service provider / the software company ) .Types of software maintenance : there were only three few years back, but present there are FOUR ( 4 ) types of software maintenance types / kinds are defined .Corrective Maintenance - corrective maintenance means a REACTIVE modification, done in the software product after the delivery . The purpose of corrective maintenance is to correct / or fix discovered ( or user reported ) problems in the system .Adaptive Maintenance - adaptive maintenance is also a modification done after delivery, in order to keep the software product usable in changing ( or changed ) environments / business environments . If this is not done properly by the time of change, business opportunities will be lost .Perfective Maintenance - a software should be efficient / less resource consuming / and should be easy to cope with . Perfective maintenance is done in order to improve the software performance ( after a change in the software or / the environment, the performance of the software changes ) . Also improving the maintainability is a concern .Preventive Maintenance - of course as it sounds, it's just PREVENTING . Preventive Maintenance is done, to detect and correct latent ( not developed ) faults before they become effective faults . This simply means the prevention of future problems .-------------------------------------------------------------------------------------------------EXTRA READING :Software maintenance sounds like, " ONLY ERROR CORRECTING ", but IT'S NOT that . 80% of the software maintenance is NON - CORRECTIVE activities ( activities which are not used to correct faults, but for other purposes ) . However, software maintenance issues can be seen in two perspectives, one is managerial issues and the other is technical issues . Managerial issues can be alignment with customer priorities, managing the staff, estimations . Technical issues may be limited understanding, impact analysis and testing .In software maintenance, SOFTWARE MAINTENANCE PLAN and SOFTWARE MAINTENANCE PROCESS are also KEY considerations . Software maintenance plan is the pre planning which should be very accurate ( this plan includes about user's requirement changes / or change requests, budget etc ) . Software maintenance process is the sequence of steps followed during the software maintenance process . which includes,Implementation ProcessProblem and modification analysis processProcess acceptance of the modificationThe migration processLast maintenance processetc ...----------------------------------------------------------------------------------------------------Hope you liked this article,CHEERS !Dileesha Mebox
A managerial approach which is concerned about making organizations or companies fully-operated and eliminate every tiny mistake in the business. Note: this is my own analysis.
The past tense of the verb "hear" is "heard". If you mean the word as in, "My hearing is quite good," the word is a gerund in that case, and has no past tense. The compound auxiliary verb progressive "be hearing" has the past tense "was hearing", perfective "have heard" has the past tense "had heard", and progressive-perfective "have been hearing" has the past tense "had been hearing".
Software maintenance is an important component of software development. Maintenance involves debugging the software, and releasing periodic updates to correct problems and make the software work better.

The prefix geo- means "Earth." Ge- is a common Germanic perfective prefix, now extinct in English except in some fossilized words such as y-clept ( "called").
