If software is a medium through which you connect with your customers, then you must pay attention to Software Maintenance. Up-to-date software with no performance issues and on-time catering to customers’ needs always wins users' hearts.

What is Software Maintenance

What is Software Maintenance?

Software Maintenance is one of the continuous and in-demand processes of the software development life cycle. It ensures modifying, upgrading, or altering the software to enhance performance, meet current Software trends, rectify bugs, re-engineering, documentation, and porting & migration.

It also means that Software Maintenance is a continuous process, unlike development and deployment. It’s an ongoing process because new feature(s) will continually be added. And with that, there might be chances of bugs as well. Therefore, knowing about software maintenance and everything revolving around it is important.

What is the Objective of Software Maintenance

Software Maintenance is always undertaken after identifying several bugs or performance issues. It can even be performed when you want to introduce new features to benefit its users. Apart from this, there are seven types of Software Maintenance, which are as follows:

Enhance User Experience

Enhance User Experience

Software maintenance is also performed when new features or functionalities are introduced. This happens when ensuring the user stays engaged with and keeps using the software.

Security Updates

Security Updates

Security becomes a top priority when it comes to software maintenance. Users look up to software with which they can share their credentials. Therefore, preventing malware attacks and keeping software reliable for users is one of the core objectives of software maintenance.

Achieve High User Satisfaction

As the name suggests, Maintenance is performed when there is a critical issue that not only hampers user experience but could even fail your Software miserably. Emergency Maintenance restores software to normal operations, eliminating all users' challenges.

Regulatory Compliance

Regulatory Compliance

Software needs to abide by regulatory standards & guidelines. This maintenance list ensures your software complies with all the regulatory compliance requirements. Software that strictly adheres to standards always performs well and has a high user abandon ratio.

Comply with Regulatory Norms

Comply with Regulatory Norms

One of the core objectives of software maintenance is to comply with legal and regulatory standards so that users feel secure sharing their credentials.

9 Challenges of Software Maintenance

Once you are well-acquainted with the meaning and objective of software maintenance, you must take advantage of challenges.

  • Difficulty in Understanding the Initial Code
  • A new developer often needs help understanding another developer's original code. On top of it, if the original code needs to be better written, it will definitely create confusion and errors. All these make the software maintenance process time and manpower-consuming.

  • Obsolete Systems
  • Another challenge on the list is maintaining software built on obsolete technologies. Because the original developer who created the software back then might no longer be available, the new developer needs to understand first and then overcome the ongoing challenges with new-age solutions. 

  • Scope Expansion
  • New features will always be added, resulting in scope expansion. But it can even make software maintenance challenging since it increases the complexity of your software. And this leads to unnecessary wastage of resources, which is not acceptable at the stage when your software is already available for public use.

  • Dependency Management
  • Since multiple third-party libraries, frameworks, and components are involved in the software, keeping all the dependencies compatible becomes challenging.

  • Unpredictable Environments
  • Software is made to work in different environments, hardware systems, operating systems, and configurations. The challenge is ensuring stability and compatibility across different environments, which is quite time-consuming.

  • Lack of Resources
  • Not only manpower but budget and time are also crucial factors in maintaining software. Since there are development priorities, managing everything at a time becomes difficult.

  • Coping Up with Business Requirements
  • Adapting and integrating new business trends and maintaining software built with old technology can be challenging since it will require understanding the software's technicalities.

  • Technical Debt
  • It is an accumulation of neglected bugs and errors over time. It becomes challenging to overcome the tech debt while also maintaining the software development.

  • Following Maintenance Routine
  • Addressing high-priority issues and maintaining corrective, adaptive, or perfective maintenance simultaneously is one of the challenges of software maintenance.

4 Types of Software Maintenance

Corrective Maintenance

A reactive approach toward fixing bugs and defects (identified post-software deployment or in a live environment) is called corrective Maintenance. This reactive measure aims to make the Software function smoothly and cater to customers’ demands without hassle.

This ensures the correction of software defects, bugs, and errors. Corrective maintenance can be performed when:

  1. Software failure due to faults, negligence, invalid code, or tests
  2. tests Bugs notification by users

Perfective Maintenance

When there is a dire need for new features, or your Software is overloaded with unwanted or obsolete features, it becomes necessary to implement perfective Maintenance. Following this Maintenance process helps to make Software smooth and enhance user experience.

Perfective maintenance ensures:

  1. Identifying and resolving bugs to prevent catastrophic events
  2. Strengthening security and overcoming challenges
  3. Providing user support whenever required

Adaptive Maintenance

Adaptive Maintenance becomes helpful in meeting customers’ demands and changing business requirements, best practices, operating systems, or technologies. Once the Maintenance is performed, it is checked whether or not being compatible and operational with the new environment.

Adaptive Maintenance aims to alter when:

  1. Come across evolving operating systems due to newer technologies, legal regulations, rules, and policies.
  2. Demand from end users for new products or software
  3. Already predicted the potential software threat or vulnerability

Preventive Maintenance

Contrary to Corrective Maintenance (reactive approach), this is a proactive approach to Software Maintenance. Instead of panicking when something goes wrong, Preventive Maintenance detects and prevents bugs and defects from happening. As a result, there will never be Software downtime, and users will access your Software without any trouble.

Besides, there will be:

  1. Increase in lifespan of the machinery and reduced maintenance cost
  2. Improvement in maintenance activities
  3. Business sustainability and elimination of catastrophic events

What is the Process of Software Maintenance/7 Phases of Software Maintenance (Phases of SMLC)

Software Maintenance is one of the crucial phases of the software development life cycle (SDLC). Like the entire SDLC, even software maintenance has a life cycle called software maintenance life cycle (SMLC).

  • Phase 1: Finding Out Software Maintenance Requests
  • The foremost phase of the software maintenance life cycle is identifying the maintenance requirement. The process is automated and manual, meaning you can run logs or sort out user error messages to make a list of the maintenance requirements. But before doing so, each maintenance requirement is individually analyzed to set priorities.

  • Phase 2: Analysis of Maintenance Request
  • Standard operating procedures define the responsibilities needed to execute a particular task. For automation, there should be clear and defined steps to transform the process from the age-old concept digitally.

  • Phase 3: Design of Replacement Model
  • The design phase begins once the analysis phase is completed and ready with the maintenance requirement as per the priority. The modules or new frameworks are prepared. Besides, test cases are also created to ensure the safety and security of the newly designed model.

  • Phase 4: Executing the Required Changes
  • This is the execution phase where a new framework is added, new features are added, and newly written code is processed. Considering the structure design prepared in the design phase, all the new models are coded accordingly.

  • Phase 5: Testing the Changes
  • Now that new changes are made, regression testing is performed to inspect for bugs, errors, and defects. Post-regression testing, it is also ensured that there is no new flaw detected in the modified software.

  • Phase 6: Performing Acceptance Testing
  • This phase involves third-party users. It happens with dummy testing to identify if the modified system works properly.

  • Phase 7: Delivering the Software
  • Lastly, it’s time to deliver the software to the client when everything works swiftly and smoothly.

Factors Affecting Software Maintenance Cost

When choosing process automation, you must know how much it will benefit you and your business. Let’s look at all possible business benefits.

Technical Factors

The technical factors discuss more or less software maintenance from the core concepts, which are:

Programming Languages Selection

Software built with high-level programming language is easier to maintain and understand than one built using low-level languages. This needs to be kept in mind that programming languages play a crucial role in defining software maintenance costs. 

Programming Style

Another factor determining software maintenance cost is the programming style. It includes how developers write the code, which decides the learning curve of the software and, subsequently, the updating and understanding of the software.

Validation & Testing

It is said that the more time spent defining and testing the design, the fewer the chances of bug detection, lowering software maintenance costs because the type and complexity of bugs determine the cost.

Configuration Management & Techniques

Keeping configuration management techniques intact can save much money in software maintenance. But for this, you must maintain uniformity in system documentation.

Module Independence

This means the capacity to resolve even complex software problems without affecting other parts of the website or application.


One of the technical factors contributing to lowering your software maintenance cost is properly documenting your software’s development.

Non-Technical Factors

External Environment Dependencies

What can shoot up the software maintenance cost mostly depends on the external environments and not adapting to the changes. The software maintenance cost will be lower if you keep updated with the external environment modifications. 

Lifecycle of Software

Every software has a lifecycle, and obsolete ones require hardware change. As a result, the conversion costs remain above the rewriting cost.

Team Stability

A new custom software development team member can take a while to cope with the development process. And the more time it takes, the higher the software development cost.

Hardware Stability

Hardware plays a crucial role in developing software. There will be zero software maintenance costs if the software remains steady on the single hardware throughout its lifecycle.

The maintenance process may take away 60-70% of your development cost had it been built with obsolete technology, resulting in developers facing challenges in finding defects or bugs.

But the software maintenance cost can be lower by following several factors:

  1. Abiding by transparent development processes
  2. Adhering to programming principles
  3. Documenting everything
  4. Hiring experienced software developers
  5. Resolving tech debt

These basic factors help in lowering software maintenance costs to a greater extent.

Let us show you how mobile application software maintenance costing works:

  1. Firstly, an application hosting server is required, costing somewhere between $70-$350/month. Hosting fees depend on the active users, the app’s content, and predicted growth.
  2. iOS & Android account fees are $99 and $25, respectively.
  3. Free and paid software licenses for iTunes and EDA tools, respectively.
  4. Reserve upto $1000 for SaaS account fees
  5. Hiring a software developer can cost you $23/hour or on a fixed basis for 80 hours. A single bug takes an hour to rectify.
