After a decade of stable operation, what led you to a full overhaul at this point?
The existing system had run stably for a long time, but as the technology landscape and ways of working changed significantly, it began to show limits in accommodating new requirements. To respond to shifts in the web environment, growing demand for mobile work, and the expansion of job-based HR systems in particular, we needed to move to a more flexible and scalable system. As we operated the organization across headquarters and nationwide sites, HR and training data kept growing, and there were increasing calls for real-time processing and user-centered services beyond simple lookups. The need for an integrated platform to support all of this grew.
Could you tell us more about why integrating HR & labor management with e-HRD became the core of the project?
Previously, HR and training information had to be checked and managed in separate systems, but after integration we can handle the work on a single platform. Improving data connectivity and the user experience was the core goal of the integrated build. Securing long-term maintenance efficiency and laying a foundation that can respond to changing HR policies and work environments were also important drivers.
After moving to the web-standard-based hunel 5.0, what change do you feel most in daily work?
The biggest change is improved usability and accessibility. Dependence on specific environments has decreased, and the service now runs reliably across various browsers and devices. As usability improved, user inquiries dropped and work efficiency rose.
| Before | After |
| HR & labor management and e-HRD run separately; data checked and managed individually | Unified processing on a single platform; data fully consolidated |
| Dependent on specific browser environments; no web-standard support | Web-standard based; reliable access on any browser or device |
| No mobile HR; field tasks could not be processed on site | Leave, business-trip requests and more handled anywhere via mobile |
| Could not accommodate job-based HR changes; structural limits | Scalable structure flexibly accommodates job-based HR changes |
| Weak foundation for data-driven HR | HR and training data unified, building a base for broader AI use |
After introducing mobile HR services, what change in employee response stood out the most?
Given that many of our employees work at field sites, satisfaction with the mobile service was high. Being able to request leave, file trip types, and check pay statements regardless of location greatly improved convenience — that was a common piece of feedback.
You said this integrated build "goes beyond a simple system improvement." Could you explain what you mean?
I believe this integrated build is significant in that it laid the foundation for a data-driven HR framework and broader AI adoption going forward. With an environment where HR and training data can be used in an integrated way, we now have the groundwork to pursue more advanced analytics and service innovation.
If a public enterprise or power-sector affiliate of similar scale is considering an HR system transition, what kind of organization would you recommend hunel to?
Any organization operating nationwide sites, or with HR and training systems that are fragmented, is well worth considering it. In particular, organizations pursuing the expansion of job-based HR, building a mobile work environment, or strengthening a data-driven HR management framework will feel the benefits.
Is there anything you'd like to say to HCG, your partner on this project?
The HCG project team showed not only outstanding technical capability but also a genuine willingness to think through problems and find solutions from the customer's side. From the PM and PL to every member, they communicated actively throughout the project and worked hard to reflect our input, responding quickly to a wide range of requirements and issues. Thanks to them, we completed the project successfully, and I hope we can continue to work together as good partners whenever the opportunity arises.
