Find answers to your questions about operations and maintenance services
HR system operations & maintenance service continuously supports stable operation, regulatory response, and feature improvement after deployment. Core services include incident response and system operations management, regulatory patches for tax law and the four major insurances, feature fixes and enhancements, and performance optimization support. Because HR systems must continuously respond to regulatory and organizational change, the absence of an operations framework can lead to incidents, legal risks, and work disruptions. Operations & maintenance is essential to keeping the HR system not just an installed program, but a core business system that runs continuously.
When internal operations staff are insufficient after HR system deployment, gaps in system management can lead to delayed incident response, missed regulatory updates, and data errors. HR systems are tightly linked to payroll, attendance, and tax — even small errors can cause work stoppages or legal risks. The solutions are to build an internal operations team or to use an external specialized operations & maintenance service. Most companies choose external services for cost and expertise reasons. HCG Operations & Maintenance replaces an internal team with a dedicated organization and standardized processes, providing stable operations even without internal staff.
Operations & maintenance modes should be selected based on system complexity and operational needs. On-site maintenance, where dedicated staff are stationed at the customer site for real-time response, suits large organizations with high system criticality, low tolerance for incidents, or frequent organizational and policy changes. Remote maintenance — request-based remote or visit support — is cost-effective when periodic maintenance and issue response are the primary needs. HCG Operations & Maintenance offers both models flexibly under annual or monthly contracts.
HR system maintenance can be handled by an in-house IT team or by a specialized operations & maintenance service. A specialized service provides high expertise based on HR domain knowledge and regulatory experience, with rapid response under SLA-based operations. Costs are also more flexible compared to internal staffing, and risk is managed reliably through proven processes and patch frameworks. An in-house team has the advantage of deep familiarity with internal systems, but may face limits in regulatory response and securing expertise. When stability and legal risk management are priorities, a specialized operations & maintenance service is the more effective choice.
Most hunel·JaDE customers choose HCG Operations & Maintenance because it secures stability, regulatory response, and operational efficiency at the same time. Maintenance is performed directly by the solution development organization, enabling fast root-cause analysis and response, immediate patches for regulatory changes, and integrated support across operations, development, and enhancements. The service is also backed by extensive customer experience and standardized processes.
