Software maintenance is an important aspect of the Software Development Life Cycle (SDLC)

“Any product without a Proper Maintenance Process Will soon end Up as Obsolete”

Any product after it is implemented requires proper maintenance to run smoothly without affecting the business operations for which the product was developed. Software maintenance is the process of changing, modifying, and updating the software and keeping it running with minimum downtime.

Generally, maintenance comes into effect once a product has been fully launched. However, for reasons such as improving the product features, correcting issues/defects, or enhancing its performance, maintenance becomes an essential part of ensuring that business continuity is not affected

There are various methods or techniques used for software maintenance. Using the right software maintenance techniques and strategies is a critical part of keeping any software performing for a long period of time and keeping the user's expectations intact.

Let's Talk

Types of Software Maintenance in the industry

There are 4 types of Software Maintenance

  • Corrective
  • Preventive
  • Perfective
  • Adaptive

Corrective Software Maintenance

As the name explains, Corrective software maintenance is an essential part of software maintenance because the product cannot sustain without changing.

Issues could arise in the functioning of the software, or the desired output is erroneous.

The ultimate goal of a product vendor is to ensure that the software is delivered with no defect leakage. However, due to changes in requirements or gaps in requirement understanding, situations may arise where the code must be fixed to reflect the changes. Corrective software maintenance is necessary to address such issues.

Preventative Software Maintenance

As the saying goes “Prevention is better than cure”, preventing an occurrence of issues will mean a lot to the stakeholders

This involves anticipating changes in technology or upgrades etc., Preventative software maintenance may seem to address small issues that might also seem insignificant. However, such an initiative may prevent larger problems in a long run. These are called hidden faults which need to be detected and corrected to ensure that they do not turn into actual faults. In other words, a delay in fixing such issues might cost a fortune if left unsolved.

Perfective Software Maintenance

New features are inevitable in software. Once the software is released into production, innovative ideas may come to the surface. End users may see the need for new features to be included for better useability.

In perfective software maintenance, the software may undergo changes terms of the following reasons:-

  • 1. Adding new features
  • 2. Removing redundant options or processes
  • 3. A feature that may not be relevant to the business

This process is vital because it helps to keep the software more relevant as per the business and user needs.

Adaptive Software Maintenance

As the name suggests, the software must adapt to the current scenario and useability.

Such situations may arise when:

  • Change in statutory rules and regulations of a land
  • Change in policies of an organization
  • Change/upgrade in Technology

When these changes are envisaged, the software must adapt to properly meet the new requirements and continue to perform.

Our expertise in Software Maintenance?

With more than 15 years of software development and maintenance, PsiberTech has an experienced team of technical people to provide support and maintenance services to our clients.

We typically provide support and maintenance services for the software that we develop and implement; in some cases, we have also provided support services for the systems developed by other developers when the entire source code is provided with proper documentation.

How can we help to keep your software performing as expected?

As part of our support and maintenance services, we will ensure that the software implemented is running seamlessly without any major issues. There will be a separate maintenance contract signed with our customer with proper SLA including the Response time to attend to the support requests.

We will analyze the software details and support needs, design the maintenance process, develop a detailed setup plan, identify a suitable maintenance model, and create a support team

We will also draft a software evolution roadmap, software performance requirements and expectations, planned security activities, and maintenance schedule to keep the software running as expected with minimum downtime.
