Chapter 5: Software Maintenance

Also, reverse engineering is to recreate the object by adding some enhancements. Planned activities include regular maintenance tasks that are scheduled in advance, such as updates and backups. Unplanned activities are reactive and are triggered by unexpected events, such as system crashes or security breaches. Proactive maintenance involves taking preventive measures to avoid problems from occurring, while reactive maintenance involves addressing problems that have already occurred. One of the most crucial tools in software creation is documentation.

What is a Software Maintenance Process

After the intranet migration was finished, we engaged ScienceSoft to provide maintenance and break-fix support for 10 months with monthly system health checks. We’d like to point out that ScienceSoft remained highly responsive during the support cooperation . Software availability, performance, security, and compliance monitoring and management. End user support – solving usage issues and minor problems, escalating more complex issues. Then, we measure the projected scope against currently available in-house resources, such as dedicated IT specialists and maintenance tools.

Typical Roles in Our Software Maintenance Teams

It assumes complete documentation of the software is available in the beginning. Moreover, it attempts to control complexity and tries to maintain good design. This is an ad hoc approach used for maintaining the software system.

  • Of course, it depends on how long you want your software to last before retiring.
  • You can also download our great new eBook – Why ASP.NET Development Services Fuels Business Growth- to learn more about this essential topic.
  • The program enters maintenance as soon as it goes live in the market.
  • Legacy software cannot keep tuning with the latest technology available in the market.
  • However, you should consider ripping and replacing the old system with a new system.

After the software launch, you may still need to add new features or integrate third-party solutions to expand the functionality. Maintenance is the final but what is software maintenance no less critical stage of the software development cycle, which newbies often neglect. The software cannot operate appropriately without continuous updates.

Implement Additional Features

Ideally, your organization will find and fix errors before users report them, but typically, many of these issues are brought to the attention of developers from user bug reports. Organizations pay for user licenses and demand a certain level of support to meet their needs. However, this level of support encompasses many aspects of value-added services.

The final step of this model is the integration of modified parts into the new system. Information gap between user and the developer can also become a huge challenge in software maintenance. There might be temporary downtime to the production of the business, while the changes are applied and configured. Faster time of delivery to the customer by increasing the automation capabilities of the existing software.

Use a Standardized Procedure When Installing New Software Releases

Over time, clients will ask for new features or functions of your software. Remember that your software can be obsolete when it has nothing new to offer. Clients might scrap your software for better and more enhanced software in the market when that happens. After a design has been finalized, developers must implement the changes in the software. Improper implementation can lead to latent faults or even errors that negatively impact functionality, so make sure to get it right.

Studies show that contribution of end users is crucial during the new requirement data gathering and analysis. This is the main cause of any problem during software evolution and maintenance. Software Reverse Engineering is the process of recovering the design and the requirements specification of a product from an analysis of it’s code. Software maintenance is also an important part of the Software Development Life Cycle. To update the software application and do all modifications in software application so as to improve performance is the main focus of software maintenance.

Modeling software patching process inculcating the impact of vulnerabilities discovered and disclosed

Search Suitable Components – The software component repository is referred by designers to search for the matching component, on the basis of functionality and intended software requirements.. Specify Components – By studying the software design, the designers segregate the entire system into smaller components or sub-systems. One complete software design turns into a collection of a huge set of components working together. Design – This is also a standard SDLC process step, where requirements are defined in terms of software parlance. Basic architecture of system as a whole and its sub-systems are created. A component is a part of software program code, which executes an independent task in the system.

What is a Software Maintenance Process

It is a process to achieve system specification by thoroughly analyzing, understanding the existing system. This process can be seen as reverse SDLC model, i.e. we try to get higher abstraction level by analyzing lower abstraction levels. For example, changing function-oriented programs into object-oriented programs. Perform Reverse Engineering, in order to obtain specifications of existing software.

Importance of software maintenance

Unlike maintenance, the scope of support service is limited to fixing small and major bugs in the software. The role of a software support service provider is to scan the system, identify the problems, and offer the most reliable solution. Software maintenance consists of a series of procedures to improve the functioning of a software app after it has been launched. It can be performed for many reasons — from fixing bugs to making tweaks so that the software aligns with your company’s objectives and customers’ needs.

Development support (L3/L4) – fixing software issues on the code and database level, customization, adding new features, software integration. The setup plan will differ depending on the specifics of the supported software and its underlying infrastructure, as well as the scope of the required support and maintenance activities. Updating software environments, reducing deterioration, and enhancing what is already there to help satisfy the needs of all users are also included in the software maintenance examples.

Importance of Software Maintenance

The life of your software does not begin when coding starts and end with the launch. Instead, it has an ongoing lifecycle that stops and starts whenever necessary. The start of its lifecycle and a good portion of the work begins at launch. Modifying software according to change in an external environment. This means perfective and refinement maintenance become increasingly important as developers try to stand out in a crowded market. For example, adding extra features might leave you with an expanded application structure, and you may need a hosting upgrade.
