MAINTAINING OUR SOFTWARE
What is software maintenance?
Software maintenance is a component of the Software Development Life Cycle. Its primary function is to modify and update software applications after they have been delivered in order to correct flaws and improve performance. Software is a simulation of the real world.
Because of the ever-changing market conditions, the requirement to maintain software programmes has increased dramatically. To survive, businesses nowadays require a proper maintenance system that ensures their systems and apps are completely functional and bug-free, correct errors, and provide help when needed.
Life of software:
The life of your software does not begin when the code is written and ends when it is released. It instead has a continuous lifespan that stops and starts as needed. Launch marks the beginning of its lifecycle and the start of a significant amount of labour. Software is always changing, and it must be carefully monitored and maintained as long as it is in use. This is mainly to accommodate internal organisational changes, but it is also critical since technology is always evolving.
Your software may require maintenance for a variety of reasons, including keeping it up and running, adding new features, reworking the system to accommodate future changes, moving to the cloud, or making other adjustments. Whatever your motivation for software maintenance is, it is critical to your company’s success. As a result, software maintenance entails more than just finding and fixing bugs. It is responsible for keeping your company’s heart pumping.
Processes of software maintenance:
Software Maintenance is a critical phase of the Software Development Life Cycle (SDLC), and it is implemented in the system via a proper software maintenance process known as the Software Maintenance Life Cycle (SMLC). This life cycle is divided into seven distinct phases, each of which can be used iteratively and extended to include customised items and processes. These are the seven stages of the Software Maintenance process:
- Phase of Identification:
During this phase, requests for software modifications are identified and analysed. Each requested modification is then evaluated to determine and categorise the type of maintenance activity required. This is generated by the system, either through logs or error messages, or by the user.
2.Phase of Analysis:
Each validated modification request’s feasibility and scope are determined, and a plan is developed to incorporate the changes into the software. The input attribute includes a validated modification request, an initial resource estimate, project documentation, and repository information. It is also estimated how much it will cost to modify and maintain the system.
3. Phase of Design:
The requirements provided in the earlier stages are used to develop the new modules that need to be replaced or updated. Test cases for the new design, including safety and security concerns, are being prepared. These test cases are designed to ensure that the system is validated and verified.
4. Phase of Implementation:
The real modifications to the programme code are made in the implementation phase, new features that support the current program’s specifications are added, and the modified programme is installed. The new modules are coded using the structured design that was generated during the design process.
5. Phase of System Testing:
Regression testing is carried out on the changed system to ensure that no defects, errors, or bugs are missed. It also ensures that no new defects in the program are introduced as a result of maintenance work. New modules and the system are also subjected to integration testing.
6. Phase of Acceptance Testing:
The user or a third party specified by the end user performs acceptance testing on the fully integrated system. The major goal of this testing is to ensure that all of the software’s features are in compliance with the modification request’s requirements.
7. The phase of delivery:
The redesigned system is distributed to the users when acceptance testing has been completed successfully. In addition, the user is given sufficient documentation in the form of manuals and help files that detail the software’s functionality as well as its hardware specs. After the system has been delivered, the client does the final testing.
TYPES OF SOFTWARE MAINTENANCE:
Depending on the nature of the software, the sort of maintenance required may change over time. It could be a simple routine maintenance activity, such as fixing a bug identified by a user, or it could be a significant event in and of itself, depending on the magnitude or nature of the maintenance. Based on their features, the following are the four main forms of maintenance:
- Corrective Software Maintenance:
Corrective software maintenance is what most people think of when they think of maintenance in general. Correct software maintenance solves problems and flaws in software applications that can affect the design, logic, and code of your product. These adjustments are usually the result of bug reports submitted by users or customers – but corrective software maintenance can help you identify them before your consumers do, boosting your brand’s image.
2. Adaptive Software Maintenance:
When the environment in which your software runs changes, adaptive software maintenance becomes critical. Changes to the operating system, hardware, program dependencies, Cloud storage, or even changes within the operating system can all contribute to this. Organizational policies or rules are sometimes reflected in adaptive software maintenance. Adaptive software maintenance is required when updating services, making vendor changes, or switching payment processors.
3. Perfective software maintenance:
The evolution of existing requirements and features in your system is the focus of perfective software maintenance. Users may notice things that you didn’t spot, or they may offer new features that they’d want to see in the product, which could lead to future projects or updates. Perfective software maintenance takes over some of the labor, both adding features that improve user experience and deleting features that are no longer useful or functional. This can include features that aren’t being used or that aren’t assisting you in achieving your objectives.
4. Preventative Software Maintenance:
Preventative Software Maintenance enables you to make adjustments and alterations to your software so that it can last longer. The goal of this form of maintenance is to keep your program from degrading as it adapts and changes. These services can involve code optimization and documentation updates as needed. Preventative software maintenance reduces the risk of running software for an extended period of time by making it more stable, intelligible, and maintainable.

ISSUES WITH SOFTWARE MAINTENANCE:
Software maintenance is an important aspect of the software development lifecycle for all enterprises and organisations. This is not something that can be avoided or skipped. It is critical to the success of your programme as well as any future development.
The majority of programming errors may be traced back to flaws in the product development process. Before you begin troubleshooting any problem, you should have a good understanding of what the problem is, how it arose, what’s that affecting.

While maintaining programming, there are a few specialised and administrative difficulties to be aware of, they are
- Costs:
Various studies have found that product support consumes 60 percent to 80 percent of the whole development cost; these studies also show that upkeep costs are primarily due to upgrades, rather than corrections.
2. Corrective Adjustments:
One of the most pressing concerns is remedial changes, as the best location for progressions is elusive. Perceiving the code base might be difficult. A moment change may necessitate engineering adjustments that take a long time if the preparatory configuration is reduced. If a complete workaround for one bug has been found, the next will be far more difficult to break.
3. Impact Analysis:
Finding the effects of a suggested change on the rest of the framework is one of the most difficult challenges in programming support. The activity of analyzing the potential effects of a change with the objective of reducing rapid reactions is known as sway investigation. The project entails examining the appropriateness of a proposed modification and assessing the risks associated with its completion, as well as assessments of the effects on properties, energy, and development.
4. Changes in Adaptation:
Adaptive alterations are frequently challenging due to a lack of information about the product being changed to. It’s difficult to grasp the numerous realities of the new invention to comply to. Similarly, affecting study and locating interfaces to new things is difficult. Concerns arise as a result of a skewed preliminary outline.
5. Comprehending the Program:
Another critical issue is system cognizance, which implies that upkeep architects should devote a significant amount of time to reading and comprehending the code and related documentation in order to gain a better understanding of its rationale, reason, and structure in order to maintain a piece of programming and to improve the nature of the software.

SOFTWARE MAINTENANCE TOOLS:
Many software maintenance tools use the concept of “concerns” and offer some or all of the following features:
• The ability to view or explore information related to a concern;
• The ability to display only relevant information;
• A mechanism to navigate through the presented information;
• The ability to search for relevant information or reduce the task context to simplify the search process.
Some of these technologies, such as FLAT3, JQuery, and ConcernMapper, are more intimately tied to our work than others. Other maintenance tools, such as Mylar, JinSight, BLOOM, and Diver, do not use the concept of “concerns” and are therefore categorised as “least related to Panorama.”
