5 Best Practices for Software Maintenance

Software development has evolved over the years, with many new technologies replacing the existing ones. However, software, once developed, does not mean it is the end of the story. It needs continuous monitoring and maintenance by the development team.

In this blog, we will focus on 5 best practices of software maintenance, which will ensure hassle free operations. 
So, let's dive straight in.

What are The Types of Software Maintenance?

Before we get into best practices for software maintenance, let's have a look at different types of software maintenance. This will help in knowing the best practices for software maintenance.

• Preventive Maintenance

 In this type of software maintenance, preventive measures are taken to avoid disruption of business operations. This is done by fixing bugs, optimizing code and updating documentation to make the software more robust.

• Adaptive Maintenance

Business processes do change over a period of time and what works today may not work after a couple of years.              Software is updated to make it compatible with changing business environments, changes in hardware or  regulatory requirements.

• Corrective Maintenance

This type of maintenance is done when there are complaints from the end user regarding issues with the software.It can be related to the UX/UI or back end of the system and may even result in crashes.

• Perfective Maintenance

 This type of software maintenance is done to improve the performance of the software. It is done by identifying areas of improvement like memory usage, execution time, and adding new functionalities as per user needs. 

5 Best Practices for Software Maintenance

So, now we know the different types of software maintenance. Let's have a look at 5 best practices for software maintenance.

#1 Documentation

This is the first thing you need to do while preparing for software maintenance. You should maintain a comprehensive document which includes all the information about the software including the architecture, design, code base, user manual and change logs. 

The documentation needs to be periodically updated as per the maintenance done. 

There should be a Service Level Agreement (SLA) between the software maintenance provider and the client. It should clearly mention scope and objectives of the service provided and maintenance schedule. 

Documentation should not be taken lightly as it serves as a roadmap for the future maintenance activities. It becomes even more crucial when some developer leaves and a new recruit has to handle maintenance. In such a scenario, good documentation ensures smooth transition and continuity.

#2 Regular Updates

It goes without saying that software maintenance requires regular updates and patches. A clearly defined update schedule should include enhancements, bug fixes and security patches. 

A mechanism for automated updates should be in place for users to receive updates. This ensures that users don't have to manually update the software being used and use the latest version at any given point in time.

Regression testing needs to be done to check whether updates are not creating new bugs. 

There has to be clear communication with the users about the availability of updates and whether they need to take any action. 

#3 Data Analysis

You should collect data from various sources like performance metrics, error logs and user feedback. This provides key insights into software performance and helps in prioritizing maintenance tasks. 

You should also study market demands and trends to know what changes need to be made to the software. 

Analyze all the data generated by performance metrics to make data-driven optimizations and identify performance hotspots.

Maintenance data analysis has been around for a long time now but now with high volume of data collected, analysis is done via maintenance data analytics software. 

Manual data analysis is time consuming and that is why you should make use of data analytics tools as volume of data generated is only going to increase. 

#4 Create/Hire a Team

You need to have a dedicated team which will take care of software maintenance. It can be an in-house team of experts or an external team. Make the decision based on your requirements and manpower you have.

Software maintenance requires collaboration between multiple players including developers, end users, support teams and testers. As a result, you need to have clear cut channels of communication.

There should be regular team meetings and collaboration tools and ticketing systems to ensure that the entire team is aware about the current situation.

#5 Proactive Monitoring

You should continuously monitor the performance of the software being used and conduct proactive testing. Make use of automated tools to identify issues before they have an impact on users. 

The testing strategy should include load testing, regression testing and security testing. This can reduce the overall maintenance required by identifying issues earlier in the software development lifecycle.

So, optimize your code to eliminate bottlenecks and improve the software performance. Work on your databases to ensure that they are well organized, as this can improve speed and response times. 

You need to make sure that the software is making use of system resources judiciously. Try to eliminate unnecessary computations and minimize memory usage to increase overall efficiency. 

Benefits of Following Best Practices

We have seen 5 best practices of software maintenance. Now, let's have a look at what you get as a result of following best practices. 

Cost Cutting

The biggest benefit of following best practices for software maintenance is reduced cost. You will not only improve the quality of your software but also cut costs over a period of time.  

Performance issues and bugs are eliminated promptly, which prevents business disruptions and costly maintenance. 

User Satisfaction

As you follow the best practices for software maintenance, changing customer requirements are taken care of. Performance improves with every update and it leads to user satisfaction, retention and brand loyalty.

Robust Security

Cyber attacks are increasing by the day and need to be addressed with utmost caution.
When you follow the best practices for software maintenance, you continuously look for loopholes and gray areas in your code and iron them out.

As a result of these activities, software systems possess robust security measures to detect and prevent hacking attempts.

Wrapping Up the Code…

With cut throat competition in almost every domain, businesses need to have the latest technology and software systems to survive and thrive. As the world becomes increasingly digital, there will be more software systems in place than ever. 

Software maintenance is a never ending process and following best practices for the same ensures efficiency, reliability and security.
