Why Software Maintenance Is Necessary?

Why Software Maintenance Is Important?

Maintaining a system is not less important than Web Application Development. It keeps solutions athletic to deal with developing technology and business environment.

Conventionally, IT service providers suggest their consumers to go for software maintenance services for the enhanced and steady performance of the system. When it comes to software, 60% costing is abide for maintenance and from total software maintenance cost, 60% is for solution enhancement, as per the writer of the ‘Facts and Fallacies of Software Engineering,’ Robert Glass.

Information Technology is one of the most refurbished domains of the industry. It acknowledges technical advancements continually that improve the efficiency of problem-solving to streamline business operations. The system is updated with the upgraded and smart technologies on a regular basis and runs seamlessly with high-end efficiency under maintenance management.

At intervals, system maintenance involves advancement in the existing solution as there are requirements of new software development as per the market shift.

What is Software Maintenance?

It is a vast management process that takes place once the procedure is done. Software maintenance includes optimization of software performance by applying advanced development, reducing errors, and eliminating useless development. Solution development can take about 2 years to build a system, while software maintenance management is an ongoing activity.

Types of Software Maintenance Services Categories:

1. Adaptive Maintenance

It is the process of conversion in the system to keep the software compatible with changing business needs and technical evolution. This type of software maintenance primarily focuses on software frameworks. Adaptive maintenance is made in response to new operating systems, platforms, and hardware to retain continuity with the software.

2. Perfective Maintenance

It is a process of modifying all elements, functionalities, and abilities to enhance system operations and performance. The software’s receptiveness and usability are solved by perfective software maintenance. It includes altering current software functionality by improving, removing, or inserting new features or functions.

3. Corrective Maintenance

Identifying errors in the existing solution and correcting them to make it works more accurately. This software maintenance activities aim to eliminate and fix bugs or issues in the software. Corrective software maintenance is usually done in the form of small updates frequently.

4. Preventive Maintenance

This service helps in preventing the system from any forthcoming vulnerabilities. Preventive maintenance defines improvements of the software, which is done to safeguard the software for the future. It is carried out to prevent the product from any potential software alteration. Preventive maintenance also makes it easier to scale or maintain your code and handle your legacy system.

Why Software Requires Maintenance?

Bug Fixing

In maintenance management, bug fixing comes at priority to run the software seamlessly. This process contains search out for errors in code and corrects them. The issues can occur in hardware, operating systems, or any part of the software. This must be done without hurting the rest of the functionalities of existing software.

Capability Enhancement

This comprises an improvement in features and functions to make solutions compatible with the varying market environment. It enhances software platforms, work patterns, hardware upgrades, compilers, and other aspects that affect system workflow. Boost your business using a technically updated solution applying software maintenance services regularly.

Removal of Outdated Functions

The unwanted functionalities are useless. Moreover, by occupying space in the solution, they hurt the efficiency of the solution. Using software maintenance guide, such UI and coding elements are removed and replaced with new development using the latest tools and technologies. This elimination makes the system adaptive to cope with changing circumstances.

Performance Improvement

To improve system performance, developers detect issues through testing and resolve them. Data and coding restricting as well as reengineering are part of software maintenance. It prevents the solution from vulnerabilities. This is not any functionality that performs in operations, but it develops to stop harmful activities like hacking.

Software Maintenance Process

Process Of Software Maintenance

In the life cycle of software development, software maintenance plan is a very crucial phase. Hence, it is executed in the system through a well-planned software maintenance process which is known as Software Maintenance Life Cycle (SMLC). SMLC is implemented in seven different phases. Those are:

Phase 1 – Identification

As the name goes, in this phase, the modifications are ‘identified’. Before implementing the changes for the requests raised, the modifications are first analyzed and classified according to the attention or maintenance it requires. This phase can be automated or manually done by a user.

Phase 2 – Analysis

The practicality and feasibility of each verified modification request are planned to incorporate changes in the software. The analysis includes validated changes or input where the cost of modification is also estimated.

Phase 3 – Design

The new framework of the software is determined according to the result of the analysis. Survey or test software is also developed for the purpose of safety and security.

Phase 4 – Implementation

This is where the main or new software framework is implemented; as in, the codes are crafted, and in the new support system, specifications are added.

Phase 5 – System testing

In this testing, the implementation of codes and specifications are tested. This stage determines if any further changes or additions are required in the new model of software.

Phase 6 – Acceptance Testing

This stage is performed by third-party end-users. They run a dummy software test, also known as a dry run test, to check if the implemented specifications are working properly, which was mentioned in the modification request.

Phase 7 – Delivery

As and when the testing phase is cleared and the developers get a green signal from the third party users, they deliver the software to the primary users.

Software Maintenance Models

There are many software maintenance models, but the most important models are:

  • Quick-fix model
  • Iterative enhancement model
  • The re-use oriented model

Quick-fix Model

Just how it sounds, the main aim of this model is to search for glitches and fix them as soon as possible. The main advantage of the quick-fix model is that it works very rapidly at a low price. The approach of this model is to modify the coding with minimal consideration.

Iterative Enhancement Model

The primary nature of the changes in this model is iterative. Based on the analysis of the existing system, the changes are incorporated in this model. It requires complete documentation of the software that is available before making any changes.

The Re-use Oriented Model

In this model, the part of the existing system that is in the position of using is identified; hence it is called the ‘re-use oriented model’. After analyzing, this model goes through changes or enhancement as required.
