What is software maintenance?
Software maintenance refers to changes made to software after it’s been deployed or “delivered” to the end user.
Any business that wants its software to remain relevant and usable must ensure that the software is adequately maintained. Engineers often liken software maintenance to automotive care. Just as your car requires upkeep (like oil changes, tire pressure adjustments, and brake checks), custom software requires constant upgrades and updates—sometimes pricey ones that come out of the blue.
And, just as a car might slowly deteriorate without maintenance, so can software.
It’s important to anticipate and budget for software maintenance costs before embarking on custom development.
Why Regular Maintenance Matters
You’ve dedicated time and money to creating custom-built software for your business. Why wouldn’t you want to make sure it continues to function properly after it’s launched?
Regular software maintenance is a must if you want to set your business up for long-term success. Listed below are some of the top reasons why maintenance matters:
Save Money
When you first learn about the cost of maintaining custom software, you might question the validity of this benefit. How is it possible to save money when you have to invest a certain amount each month or year in software maintenance?
Think about it this way. Which is likely to be more expensive: The cost of maintenance or the cost of repairs?
In most cases, repairs are going to be more expensive.
You can save more money in the long run if you make regular maintenance a priority, rather than waiting until something goes wrong with your software.
Save Time
You can also save a lot of time (and money, for that matter, because time equals money in all types of businesses) by investing in regular software maintenance.
Again, let’s use the repair analogy. Which is likely to take more time: Regularly scheduled maintenance, or a major repair that needs to be fixed because you put off maintaining your product?
In most cases, the repair is going to take more time to complete.
This means your software will be inaccessible to your team and/or customers for a longer period of time, which eats into the productivity and/or satisfaction with your business.
Prepare for Crises
As a business owner, you know that when you fail to prepare, you prepare to fail.
If you haven’t factored regular software maintenance into your company’s calendar — and if you haven’t included it in your budget — you’re potentially creating a lot of problems for yourself, your team, and your clients should a crisis take place.
Imagine a security breach occurred, for example, because you didn’t make it a priority to maintain your software.
Would you be able to handle the financial and PR-related repercussions of that event? Wouldn’t it be better to prepare for the worst and do everything you can to prevent a crisis from happening?
Maintain Continuity
Regular software maintenance ensures the continuity of your product. If you’ve invested a lot of time and money into creating custom software, you likely want to do everything you can to ensure it survives.
It doesn’t matter if your server goes down or you have a security breach. You want your software to last, don’t you?
One of the best ways to do this is to make sure your software and all of your company’s IT systems are functioning properly. If you don’t do this, you may lose previous work or valuable data and compromise your product’s security.
Peace of Mind
Finally, speaking of security, we can’t emphasize enough the value of peace of mind.
Busy professionals like you almost always have a ton of different plates in the air at once. Because of this, you don’t have time to be worrying about whether or not your software is secure, functioning properly, etc.
When you invest in and schedule regular software maintenance, you can rest easy knowing your product is taken care of. This, in turn, frees you up to focus on other important aspects of running your business, managing your team, and making sure your company is set up for long-term growth.
What is software maintenance?
Software maintenance is part of the software development life cycle. The purpose of the service is to modify and continuously update software applications to eliminate all possible errors, malfunctions, to improve work efficiency and better system performance.
This is a very broad activity that occurs soon after the development is completed. It optimizes system performance by reducing errors, eliminating unnecessary development and applying innovations.
Full software development lasts at least 5 years, but maintenance continues at least 15-20 years and even more.
Software maintenance categories:
- Adaptive. Some changes are made to the system to ensure its compatibility with changing environments.
- Perfective. Checks on the fine-tuning of all elements of the system, the functionality and capabilities to improve system performance.
- Corrective. Detection of errors and mistakes in the existing solution and their correction to ensure the effective operation of the system.
- Preventive. Helps prevent potential system vulnerabilities.
Why software maintenance is required?
Software maintenance is needed for several reasons which are listed below:
1. Correction of ‘bugs’:
The most important part of the service is the correction of errors or in other words ‘bugs’. It is very important that the software works without problems. We recommend setting this task as a priority.
This process contains the search for errors in the code and their correction. Problems can occur in hardware, operating systems, or any piece of software. This should be done without prejudice to the remaining functions of the existing software.
2. Improving opportunities for a changing environment:
This part of the service is important for improving the current functions and for making the system compatible for changing the environment.
It extends the capabilities of programs, work patterns, hardware upgrades, compilers, and all other aspects that affect the workflow of the system. Increase the performance of your system using a technically updated solution and regularly using software maintenance services.
3. Remove obsolete functions:
Functionalities that are no longer used and unnecessarily occupy the space in the solution actually reduce the efficiency of the system. Therefore, the removal of obsolete functions is necessary. These user interface and coding elements are removed and replaced with new functions using the latest tools and technologies.
This change makes the system adaptive to cope with changing circumstances.
4. Performance improvement:
Improving system performance is making in order to meet new requirements. Data and encoding constraints as well as reengineering are part of software maintenance. This prevents the solution from being vulnerable. This is not any functionality that works in operations, but it evolves to stop harmful actions, such as hacking.
