The principal requirement during maintenance is to ensure that the existing quality of software is preserved to make the system operate and function properly along with any new enhancements that are needed because of the change in business requirements. At Nextcomm Technology Services, our specialized team uses preventive maintenance in which the overall quality of software is improved in order to ensure long-term maintainability. The possible activities in this process include:
• Removal of unreachable and infeasible code
• Simplification of procedure interfaces and restructuring
• Document and add comments to source code
• Fault removal and improved test data generation
• Application reengineering and source code refactoring
We also follow the policy of making extensive market research, upgrade impact analysis, asset management, and quality control during software maintenance to help control various risks involved.

As an added effort, our project team looks into the current state of the software, its complexity, structure, comments, dataflow and other valuable information, which is critical and need more attention, to enhance functionality, and to bring in stability, consistency and improvement into the overall performance of the application.
