Architecting Resilient HR Automation Systems: Lessons from Enterprise-Scale Deployments

As organisations continue to grow across borders and between divisions, they are also expanding into various regulatory environments; thus, the use of automated HR systems has shifted from basic administrative support system to critical business platform [1]. Once limited to just storing employee information or processing payroll; today, the HR systems directly impact the overall employee experience, the ability to uphold regulatory compliance, and a company's ability to remain operationally viable [2]. The HR service models for large companies have developed into platforms that may now conduct thousands of onboarding processes, role changes, changes in access, and off-boarding of employees across highly complex technical and legal environments [8]. Despite their importance, many organisations remain to this day reliant on HR service models that are poorly structured at their core. Most/all of these service models are highly susceptible to integration failures, scaling limitations, and regulatory complexities. As a result, companies experience problems such as frequent delays in onboarding, failure to provision access, inconsistency in data states, gaps in compliance with government regulations, and decreased trust in the HR service models. These failures are the result of tightly coupled service models, synchronous integrations between multiple systems, and inadequate resilience engineering [16]. This paper describes an Enterprise Resilient HR Automation Framework (R-HRAF) that extends the concept of resilience to HR workflow orchestration [7]. The R-HRAF provides organisations with a framework for developing HR Workflow Orchestration that is easy to design and configure, contains fault tolerant capabilities, provides automated governance and compliance awareness functionality, and allows for continuous improvement of HR workflow orchestration practices. The R-HRAF incorporates design concepts like circuit breakers, idempotent execution, externalized process definitions, and separation of duties to construct a strong foundation of resilient architecture for developing effective and sustainable HR Workflow Orchestration [16].
