What are software maintenance activities

Software maintenance refers to the process of making changes to a software system after it has been deployed. The primary goal of software maintenance is to ensure that a software system continues to meet the needs of its users and remains effective and efficient over time.

Software maintenance from the InStandart company covers a wide range of activities aimed at maintaining and improving software systems. These activities play a critical role in the software development life cycle and help solve problems, improve functionality, and adapt the software to changing requirements.

Software Maintenance benefits

Here are some of the key benefits of software maintenance made by InStandart team:

  • Enhanced Software Performance: Regular maintenance activities, such as bug fixing, performance optimisation, and code refactoring, help improve software performance, resulting in faster response times and increased efficiency.
  • Improved User Satisfaction: When software is well-maintained, users experience fewer issues and enjoy a smoother and more satisfying user experience. This leads to higher user satisfaction and a positive reputation for the software.
  • Longevity of Software: Effective maintenance extends the lifespan of software, allowing organisations to maximise their initial investment. This reduces the need for frequent system replacements, which can be costly and disruptive.
  • Adaptability to Changing Requirements: Adaptive maintenance ensures that the software can evolve to meet changing business needs and user requirements. It allows the software to remain relevant and support the organisation’s growth.
  • Reduced Operational Risks: Proactive maintenance, including security patching and preventive measures, reduces the risk of critical system failures, data breaches, and security vulnerabilities. This safeguards critical business operations.
  • Cost-Efficiency: While there is a cost associated with software maintenance, it is often more cost-effective than neglecting maintenance and dealing with major system failures or replacements. Preventive maintenance helps identify and address issues before they become costly problems.
  • Support for New Technologies: Adaptive maintenance enables the integration of new technologies, ensuring that the software remains up-to-date and capable of leveraging the latest advancements.

Software maintenance categories

Categories of software maintenance provided by InStandart:

Corrective Maintenance

Corrective maintenance is often the most immediate and necessary form of maintenance. We identify and rectify software defects, bugs, and errors. These issues can arise from coding errors, data corruption, hardware failures, or changes in external interfaces. Corrective maintenance ensures the software continues to function reliably and effectively.

Adaptive Maintenance

Adaptive maintenance focuses on making necessary modifications to the software to accommodate changes in the environment. We  update the operating system, hardware, or external systems with which the software interacts. By staying current with external changes, the software remains compatible and operational.

Perfective Maintenance

Perfective maintenance aims to enhance software functionality without changing its core features. Our team optimises performance, improving user interfaces, and enhancing the user experience. These improvements contribute to a more efficient and user-friendly software system.

Preventive Maintenance

Preventive maintenance involves proactively identifying potential issues before they lead to software failures. Our team does code reviews, software inspections, and performance monitoring. By addressing potential problems early, preventive maintenance helps reduce the risk of critical failures and ensures the software remains dependable.

Software Maintenance process

InStandart’s software maintenance process is a structured and organised approach to managing and supporting software systems after their initial development and deployment. It includes a number of activities:

  • Issue Identification: Our team begins with the identification of issues, which can include bug reports, feature requests, performance problems, security vulnerabilities, and other concerns.
  • Issue Prioritisation: Once issues are identified, we prioritise them based on their severity, impact on the software, and business requirements.
  • Planning and Scheduling: Our team creates a schedule and defines the scope of work for addressing the identified issues. It includes resource allocation, budgeting, and setting timelines for the maintenance tasks.
  • Implementation: The implementation phase involves carrying out the actual maintenance activities, which can include bug fixing, code refactoring, security patching, performance optimisation, and more.
  • Testing and Validation: Our team performs various testing methods, including functional testing, unit testing, integration testing, and user acceptance testing.
  • Documentation Updates: We document all changes made during maintenance. This includes updating technical documentation, user manuals, and release notes.
  • Release Management: It includes version control, packaging, and distribution of the updated software.
  • Security Audits: Regular security assessments and audits are conducted to identify vulnerabilities and ensure that security best practices are followed.
