Does Every Change in HR Law Require Development?

Why does a legal change immediately become a development request?

When a change in employment law is announced, HR first checks the effective date. The next questions are often practical: When will the system be updated? Where should we submit a development request? The law has a fixed start date, but HR does not control the development schedule.

For an HR leader or CEO, the delay is more than an inconvenience. While the system operates under old rules, payroll calculations or attendance policies may be applied incorrectly. The company remains responsible for the result. However carefully a policy was designed, it cannot reduce risk if the system takes too long to reflect changes in law or internal rules. The critical issue is how quickly the system can keep up.

Why does routing every change through development slow things down?

In systems where HR policies are hard-coded during implementation, almost every later adjustment becomes a development request. A new contribution rate, a change in eligibility, an additional approval step, or a revised leave rule follows the same path: HR documents the requirement, the internal team or external provider queues it alongside other requests, and the update goes through development, testing, and deployment.

The process itself becomes a bottleneck. Even a company with its own developers may take weeks; a midsize or smaller business reliant on an outside provider can wait longer. A regulation takes effect on its prescribed date regardless of the development backlog.

In the meantime, HR may build separate spreadsheets to recalculate results manually. The system and the values actually used must then be maintained in parallel, with retrospective corrections if a case was processed incorrectly. The problem extends beyond Korea. In its “Top Five Workplace Policy Issues for 2026,” SHRM notes that differing leave rules across jurisdictions add to the compliance burden for employers operating in multiple locations. The jurisdictions differ, but the operational question is the same: how quickly can an HR system reflect new requirements?

Would a SaaS system solve the problem?

A subscription-based system can have a clear advantage for standard statutory changes: the provider can update the product for all customers. That does not guarantee support for each company’s own policies. A SaaS product with a narrow range of configuration options may struggle to represent distinctive allowances, complex approvals, or company-specific promotion and performance rules. A deployed system may represent those rules in depth, yet still require a development request for every subsequent change if its implementation relies heavily on custom code.

The useful question is how to achieve both: enough depth to represent company policies and enough flexibility to change them quickly. A configuration-driven deployed system seeks to do this by managing recurring changes through settings rather than code.

Three types of change: patch, configuration, and development

The first step is to identify the nature of the change. Not every legal or policy update should be handled in the same way.

The provider should deliver common statutory changes that apply in the same way to every customer, such as changes to social insurance rates, the minimum wage, or tax rules. Company-specific policies require a different response. How an organization implements a revised requirement in its leave rules, eligibility conditions, or approvals can vary, so frequently changing rules should be configurable. New calculation models, data structures, or interfaces may still require development.

This distinction is a longstanding HR technology challenge. Josh Bersin has observed that replacing or reimplementing large HCM platforms when they cannot adapt to organizational change can cost tens of millions of dollars and take years (“The Next Generation of HR Software Has Arrived, Finally,” 2023). A good HR system does not eliminate development. It makes clear which changes belong in a patch, a configuration setting, or a development project.

How well does your system reflect policy and keep up with change?

Consider these questions about the system your organization uses today:

• Does it represent your actual allowance rules, approval structure, leave policies, and promotion and performance criteria, or have you had to reshape your policies around its standard features?
• Over the past year, what share of policy changes could HR make through configuration without submitting a development request?
• How many days did the most recent change take from request to production, and did HR need manual workarounds in the meantime?
• Is HR interpreting and entering common statutory updates, such as social insurance rates or tax changes, that the provider should supply?

Difficulty with the first question points to a lack of policy depth. Difficulty with the next two points to slow adaptation. A configuration-driven system should address both: represent the organization’s policies without forcing them into a narrow template and allow recurring rule changes through configuration. The breadth and depth of available settings are therefore key considerations.

JaDE handles each type of change in its appropriate way

JaDE does not leave every legal update to HR or every policy change to developers. HCG supplies package updates for statutory changes common to customers, such as revisions to social insurance rates and tax rules. This reduces the need for HR teams to interpret and implement those updates individually.

Company-specific rules are handled through configuration. JaDE offers approximately 590 settings across personnel administration, organization management, time and attendance, performance, and payroll. HR teams can represent different policies and adjust recurring rules, including leave eligibility, approval processes, allowances and deductions, routing, and request types, without submitting a development request for each change.

When a requirement falls outside those settings, such as a new calculation structure or data model, a JaDE Implementation Consultant (JIC) reviews it with the customer and determines what development is needed.

JaDE supports implementation in an average of three to five months through its standardized product architecture and range of configuration options. This also makes scope and timelines easier to plan than a heavily custom-built approach. To review how your HR system handles statutory and company-specific changes, speak with the JaDE team.
