Essential Software Maintenance Guide: Best Practices, Phases, and Models

Software is integral to business operations in this increasingly digitalized world, enabling them to stay agile, deliver services effortlessly, and provide personalized customer experiences. However, simply developing and successfully launching software is insufficient to ensure sustainable business success. Continuous maintenance is crucial to remain competitive, meet evolving user expectations, and for optimal performance. What is the software maintenance process? Software maintenance service refers to changing, modifying, and updating software to prevent issues, enhance functionality or performance, and keep it up and running. It serves as the backbone for extending the utility and efficiency of software well beyond its initial launch.

Moreover, software maintenance management not only helps companies extend the utility and performance of software post-launch but also helps them risk declining performance, security vulnerabilities, loss of competitive edge, and obsolescence. Without effective software maintenance practices or an in-depth understanding of its methodologies, businesses risk facing challenges such as declining performance, security vulnerabilities, loss of competitiveness, and eventual obsolescence. To address these critical concerns, this blog will discuss the software maintenance plan, its importance, type of software maintenance, models, and strategies for effective software maintenance and support.

Software Maintenance: What is It & Why It Matters?

According to Gartner, Software maintenance service refers to “Updating software, adding new functions, fixing bugs, and solving problems.” This means that software maintenance management is a process that helps businesses upgrade, modify, and update software to meet client needs and the evolving user’s expectations. Thus not just improving the software overall by addressing faults or bugs but also increasing performance, viability, and more.

Why is Software Maintenance Important?

It is a crucial part of the software development cycle and helps developers in:

• Lowering the long-term total cost of ownership with tech debt reduction practices, feature enhancement, and bug fixes to keep software stable, efficient, and modern.
• Meeting the changing user requirements and hardware/software requirements accordingly with time.
• Ensuring the viability and relevancy of the software from its inception through deployment and ongoing usage.
• Reducing unwanted side effects and ensuring the system continues satisfying user requirements.
• Extend the lifespan and enhance the efficiency of software systems throughout a software product’s lifecycle.

Exploring the Key Software Maintenance Models: An Overview

Software maintenance and support models are different methods to modify or upgrade your software. However, the process may depend on your business goals, industry, tech team’s expertise, and the market’s predictive trends. So, choose the right model from the following options:

1. Quick-Fix Model: This model works to resolve software problems immediately, without thinking about effects over time. Developers use it to solve critical problems while looking for faster ways to work.
2. Iterative Enhancement Model: The model gradually improves the software through several steps. Each round involves making plans, building software, implementing it, and testing it to improve the software piece by piece.
3. Boehm’s Model: This method has two names: the Spiral Model and Boehm’s model. It evaluates software quality through sequential levels: high-level traits (Maintainability, Portability, As-is utility), intermediate factors (Reliability, Efficiency, Testability, Understandability, Usability), and primitive features (device independence, accessibility, accuracy). This allows developers to adjust plans and go through steps more than once.
4. Reuse-Oriented Model: This model shows how older software parts identify reusable components in existing systems to reduce planned project expenses and completion time. It also shows how to find parts of earlier software that still work and can be used again, adding them to the current project without system alterations.

Phases of Software Maintenance Life Cycle

Software maintenance management has different stages, just like software development phases. So, to help you better understand the software maintenance and support process, here’s the framework of the cycle:

1. Problem Identification

The tech team finds software update requests from users and gives each one a unique ID. Following the classification, Developers rank each requested change to know what needed work before starting on others.

2. Problem Analysis

In this phase, programmers determine all the software changes they need based on five critical parts: validated requested changes, cost estimates, details about the programming code, and required documents.

3. Design

Developers start writing new program parts to replace or adjust parts of the code. They create test scenarios to ensure the system is running safely and protected from any vulnerabilities. It includes the following:

• The way we describe software blocks of code must follow standard guidelines.
• Changing the previous list of changes
• Writing test plans for fresh product designs
• Building regression tests

4. Implementation

The SDLC team updates computer programming, adds design notes and new features, and adjusts the entire program. The inputs are based on software source code, change software, and project paperwork to make the required modifications.

5. System Test

This checks how the adjusted, added, or modified changes interact with the system to ensure that it remains bug-free after the changes as the software runs. Testers also put together test review reports and updated software guides.

6. Acceptance Test

This phase tests the fully integrated system to verify that the new features meet the requirements stated in the modification request. The input attribute includes acceptance test plans, cases, procedures, and a fully integrated system.

7. Delivery Phase

The team delivers updated software to the end user with exhaustive documentation, including manuals and help files, that describe how the modified, updated, or removed changes will impact the software’s operation and hardware specifications.

Uncovering the Types of Software Maintenance for Optimal Performance

There are four commonly known types of software maintenance services, these are:

1. Corrective Maintenance: It aims to correct any remaining errors, such as poor database design, bugs, viruses, security vulnerabilities, etc. This type of software maintenance addresses errors and faults that could impact various parts of your software.
2. Adaptive Maintenance: Modifies the software to match changes in the ever-changing environment. This is done to help companies ensure that the software keeps up with expected or unexpected changes and continues functioning correctly.
3. Preventive Maintenance: prevents the system from becoming obsolete and involves the concepts of reengineering and reverse engineering. In this process, an old system with old technology is re-engineered using new technology. This type of software maintenance prevents the system from dying out and improves its scalability and reliability in the future.
4. Perfective Maintenance: It ensures your software meets your users’ or systems’ evolving requirements and features and keeps it relevant as the market and user needs change. This may include removing or adding system functionality, improving speed optimization, computational efficiency, etc.

What is Software Maintenance Service Cost?

Maintaining a product is generally estimated to cost more than 90% of the software’s total cost.
