Software Maintenance As a Service: Our Key USPs

4 Minutes Read

Maintenance as a service for custom software is a natural extension of our custom software development services.

We have been maintaining and providing related assistance for a long time because we have produced various complicated software systems. We invite you to take advantage of this opportunity.

In today's technology-driven world, no business can afford to fall behind in terms of technology, platform, or tools. So, software maintenance lifecycle used by leading businesses are focused on monitoring the performance and usability of an application's software release to ensure its competitive market viability.

You'll be faced with the requirement to start supporting, maintaining, and correctly "evolving" your software system the day it goes online.

Let’s go through a few common questions- what is the definition of software support or what is the definition of software maintenance? Is there any difference?

Yes, there is a difference between support and maintenance!

While these two concepts are sometimes confused, the difference between support and maintenance can be distinguished by the urgency with which they are approached.

While software support is defined as reactive development aimed at correcting broken software (or "bugs"), software maintenance is described as proactive development aimed at adding new features or triaging low-priority "bugs" that do not affect the software's design or user experience.

Let’s see these development types in detail.

Types of Development in Maintenance as a service

There are two kinds of development in maintenance as a service. They are:

  1. Development that is reactive (on-demand)
  • End-user support (L1) — Software support troubleshooting and resolving small difficulties, as well as escalating more complicated issues.
  • Application support (L2) — diagnosing software and resolving performance, configuration, and security concerns.
  • Development support (L3) – resolving software difficulties at the code and database level, customization, new feature additions, and software integration.
  • Contracted support (L4)- Outside support for problems not supported by the organization
  1. Continuous Development - Software Maintenance, software availability, performance, security, and compliance monitoring and management
  • Quality assurance activities (including regular code reviews),
  • Infrastructure improvement (e.g., cloud resource consumption optimization).

General Level of Software and Application Support 

IT Support Levels Function Support Methodology Staffing Requirement
L1 Service desk delivery and basic help desk resolution Support for fundamental client concerns that require IT intervention, such as resolving usage issues and fulfilling service desk requests. Lower-level technical professionals who have been taught to fix recognized problems and complete service requests using scripts.
L2 Technical assistance in depth For difficulties that tier 1 can't manage, experienced and skilled technicians examine the situation and offer remedies. Support staff have extensive product or service knowledge, but not necessarily the engineers or programmers that conceived and developed the product.
L3 Expert product and service support For problem resolution or the construction of new features, you'll have access to the most advanced technological resources accessible.
Tier 3 technicians employ product designs, code, or standards to try to duplicate problems and identify root causes.
Depending on the origin of the problem, the company decides whether or not to develop a new solution.
Tier 3 specialists are the most highly skilled product specialists and may include the product or service's creators, principal architects, or engineers.
L4 Outside support for problems not supported by the organization Marketing assistance, high-end application security, machine maintenance, and other outsourced services are examples of contracted support for products not offered directly by the organization.
Problems or requests are forwarded to tier 4 support, which is then monitored for implementation by the organization.
Preferred vendors and business partners who provide support and services for your company's products.
