The maintenance process starts right after the user purchases particular software or technology system. Like a human, software and applications require visiting doctor (the technical support engineer) regularly to maintain good health.
Mobile app maintenance and enhancement services modify the components of the system to improve performance and fault correction. It helps the application to adapt the upgrades and environmental changes. Mobile app maintenance services are useful when the applications continuously in action.
The application and software maintenance is mandatory for companies who are still using legacy (traditional) technology and systems. But with advancement in technology, companies depend more and more on software and applications to make management faster, easier and efficient. Companies perform app maintenance in order to bring end-user satisfaction.
Types Of Application Maintenance
There are different types of maintenance procedures and techniques provided by maintenance service providers to make a system up to date and more viable. Following some of key maintenance procedures:
1. Emergency Maintenance:
The problems and errors in system are unpredictable. The companies use emergency maintenance and support when an unscheduled and unseen problem occurs. This kind of maintenance is so common as many users need support during the time of crisis.
For example, fixing up inactive Internet connection in office is an emergency maintenance situation in the corporate world.
2. Perfective Maintenance:
Perfective maintenance is an implementation of new or changed user requirement in an application. It makes functional modifications without affecting the regular behavior of applications and software. Perfective maintenance services make changes in the source code to bring new functionality according to user requirements.
For example, the application or software receives updates frequently to unlock the important features.
3. Adaptive Maintenance:
In adaptive maintenance practices, changes are made to the applications in order to keep the system updated with the change in working environment such as hardware or operating system. The term environment refers to the influences and conditions which act on the system. This kind of maintenance ensures the compatibility of an application with newer versions of operating system.
For example, Bluetooth drivers for Windows 7 and Windows 8 are different. Hence users need to make certain modification or installation.
4. Preventive Maintenance
Preventive maintenance demands performing actions to stop the occurrence of errors. It tends to lower down the software complexity, as a result, improving application understandability and maintainability.
Preventive maintenance includes code optimization, documentation updating, and code restructuring. Documentation updating implies modifying the documents affected by the changes in order to match the current state of the system. Code optimization involves change in the programs uses storage space for faster execution. While code restructuring includes program structure modification to reduce the complexity of source code.
5. Corrective Maintenance
Corrective maintenance repairs the defects and faults found in day-to-day application functions. It deals with the errors related to application logic, design and coding. All these errors are referred as residual errors. The bug reported by users in the application generally initiate the corrective maintenance for the application.
Importance Of Application Maintenance
Generally, application developers spent 75% work time for the application development and remaining 25% in modification when things come to maintenance. Detecting and fixing bugs in the application is not the only task in application maintenance. But developers should require to make sure the application’s adaptability along with changing business requirements.
For example, the banking systems now rely on softwares to perform various transactions. If a bank decides to use single currency system, then clients and users of the bank all over the globe need to modify their currency system too.
But before implementing application maintenance for system, following things should be considered carefully-
- Total number of systems that require applications maintenance
- Total number of legacy system that requires frequent maintenance
- System lifecycle cost estimation
- Proper schedule
- Impact on current operations
Maintenance For Legacy Systems
Many companies are still using with legacy systems in order manage their daily operations. IT sector consider the legacy systems as old and outdated one. Even though it’s outdated, they are still common in many companies. Hence, companies always want to protect sensitive data stored on such legacy systems.
Maintenance for the legacy system is as important as the new systems. The maintenance services for legacy system includes-
- Database and platform migration
- Data cleansing
- Modification in application source code according to current trends
- To make working of legacy system seamless across various platform
- Provision of expert engineers who knows legacy system codes in order to merge them with latest systems
Mobile app support maintenance services are really important to keep seamless workflow in business operations. Daily new application and software introduced in the market which provides many useful features to their users. But along with their utilization, regular maintenance of these applications is also necessary. Companies can look for decent maintenance services in order to provide regular technical supports to their applications and software.
