The most notable thing with building a software solution is that the cycle of its iteration is not a one-time fix-remedy. In truth, it is a continuous process of fixing vulnerabilities to keep the product up and running. This is where the role of software maintenance means great virtue.

Here is our detailed rundown of the software maintenance guide encompassing its significance, types, models, and other aspects.

What is Software Maintenance?

Software maintenance holds an extremely valuable role in the SDLC or software development life cycle. The role of maintenance in SDLC comes after an MVP (minimum viable product) is launched.

So, it is the last and very important step that sets the course of productivity of your software solution, in due course of time.

However, the main purpose behind software maintenance is not just keeping the product in working condition. Rather, the focus is to keep it in a better and improved version, according to the changing market demands.

What is the End Goal of Software Maintenance?

Software maintenance is about nurturing and improving the capabilities of the software to achieve the desired goals, such as –

What is the Cost of Software Maintenance?

Software maintenance services are contract-based offers from technology vendors after the delivery and deployment of the product. The cost of such services is associated with the percentage of the original cost of software development as agreed between the vendor and the client.

In some cases, the cost could be two-thirds of the entire software development lifecycle or over 50% of the SDLC processes.

We, however, recommend you consult an experienced software development company for an exact cost estimation on your ambitious project.

Categories of Software Maintenance

1. Adaptive –

In this category of software maintenance guide, some changes that tech teams make ensure that the software is compatible with the changing environments, in terms of technologies, policies, and regulatory compliances. It is the classic form of keeping a product free from faults and errors.

2. Preventive –

It keeps software in working condition for as long as possible. This involves ensuring relevant changes are made to the product, apart from upgrades and adaptations. The goal here is to address small issues to prevent them from getting worse for the lifespan of the software in the future.

3. Corrective –

In this category, maintenance focuses on detecting and fixing errors and mistakes in the current software solution for optimized performance. The goal is to keep the product unaffected from getting impacted by faults and errors in its functionality.
