As you are now aware of software maintenance costs, next, let’s learn about the key factors that impact the software maintenance cost.

Core Factors That Influence Software Maintenance Cost

In this section, you will learn about the different factors that impact the cost of software maintenance. The factors are divided into two groups that are technical and non-technical.

According to a study by ResearchGate, software maintenance is an extensive activity that includes the improvement of functionalities, error correction, code optimization, and removal of unnecessary or obsolete functionalities. Various factors influence the cost of software maintenance. Based on the study, there are two types of technical and non-technical factors that affect software maintenance costs.

Let’s first learn about the technical factors quite in detail.

Technical Factors

1. Software Complexity

   If your software has complicated architecture, design, and functionalities, more time is required for maintenance. As the complexity increases, the time to maintain your software increases because understanding and resolving the changes becomes challenging. This can lead to an increase in costs in troubleshooting, impact analysis, regression testing, and deployment.

2. Technology Stack

   The technology stack used in your software also impacts the cost of maintenance. If complex or less popular technologies are used to develop your software, then such level of expertise work is required. For that, a high level of skilled software engineers needs to be hired which could result in high software maintenance costs due to their high hourly rates.

3. Software and Database Size

   As the size of your software or database increases, maintenance becomes challenging and complex. Because larger software has more code to maintain and also becomes more challenging to understand and change while taking care that existing functions work perfectly without any changes.

   In addition, if you have a large database, reconstruction and organizing take longer due to its complexity.

4. Module Independence

   When your software solution is developed with the combination of different modules, the software maintenance costs reduce. Each module is responsible for a specific function.

   As these modules are individual, it becomes easy for developers to resolve errors, understand functionalities, and make test changes. By simplifying the functionalities, the amount of time and effort required for software maintenance reduces and leads to less cost.

Non-technical Factors

1. Software Development Life Cycle

   If longer you use a software solution, it is more likely to require maintenance that includes updates, bug fixes, and improvements. Over time, when the technologies used in software evolve, you need to update your software to make it compatible with new systems, hardware, and software. Moreover, if your software becomes obsolete, the functionalities may need to be replaced, so the conversion cost increases.

2. The External Environment

   When your software product is dependable on third-party or external resources, the small amount of change in external resources makes it necessary to update your software. So, the software’s environment, such as workflows, reports, and third-party tools, can impact the maintenance.

   If any of these external things change, the software might need to change as well.

3. Frequent Changes in User Requirements

   As the needs of your software users change or update, you need to update your software products to meet your end-user requirements. The more frequent changes in the user’s needs, the more work needs to be done to match the expectations. This depends on the higher software maintenance costs.

Let’s now learn about the different types of software maintenance services and their cost

Software Maintenance Types and Percentage of Each

As said, there are four types of software maintenance. You can opt for any type of software maintenance service as per your requirements. Although, you might have questioned whether each of these types has the same percentage of software maintenance cost or is different. To answer your question, we have created a table on the types of software maintenance costs.

Please note that these percentages are rough estimates and the actual distribution can vary based on factors like the specific software, its development process, its usage, and its operating environment.

In terms of percentages, many experts suggest that the annual software maintenance cost is typically between 15% to 25% of the original software development costs. However, this can vary widely depending on the complexity of the software, the quality of the original code, the skill of the maintenance team, the software’s environment, and the rate of change of the software’s requirements.

Therefore, it’s always recommended to conduct a detailed analysis considering all the factors specific to your project to get a more accurate estimate.

So far, you have learned about software maintenance costs, factors that influence the cost of software maintenance, and the percentage range of each type of software maintenance. Next, let’s learn how to reduce software maintenance costs.

How to Reduce the Software Maintenance Cost: 5 Tips

Follow these 5 tips that help you to reduce maintenance costs.

1. Implement Continuous Integration and Continuous Delivery (CI/CD)

   The use of CI/CD practices can help detect problems early, reduce integration issues, and ensure that the software is always in a releasable state. For example, a well-set Jenkins or GitLab CI/CD pipeline can detect build issues early, preventing them from reaching the maintenance stage.

2. Scheduling the Software Maintenance at a Fixed Duration

   Regularly update and refactor the software to improve performance and prevent future issues. A research study by S. Chou, Xuan Loc Pham, T. Nguyen, and T. Yu suggests that scheduling software maintenance helps you significantly reduce the cost of software maintenance. The reason is that regularly updating libraries and dependencies can prevent security vulnerabilities and compatibility issues, reducing the need for emergency patches later.

3. Opting for Quality Software Development

   High-quality code is easier to maintain and less prone to bugs. When high-quality software is developed, developers adhere to coding standards, making use of design patterns, and good documentation can improve maintainability. This might mean investing more upfront in skilled developers, but it can save maintenance costs down the line.

4. Implementing the Automation Tools

   Applying automation tools and monitoring tools help in the software development life cycle. For example, whenever the server of your software goes down or up, these tools send notifications to the software development team. When the teams instantly get notified, the right people can check the problem and resolve the issues in your software solution.

   On top of that, the use of automated processes like testing, deployment, and monitoring can increase efficiency and reduce human errors. For example, tools like Selenium for automated testing or Ansible for automated deployment can reduce the time and effort required for these tasks.

5. Implement Bug Tracking System

   Without an effective bug tracking system, you’ll find yourself trying to deal with a seemingly unending stream of issues. You might end up wasting resources on resolving minor bugs while major issues linger and potentially harm your users’ experience or your software’s security.

   This is where the bug-tracking system comes into play. A good bug-tracking tool allows you to document, categorize, and track every issue that arises. For example, when a bug is discovered, it can be logged into the system with all the relevant details like the nature of the bug, steps to reproduce it, and its severity.
