Introduction: Background

As part of their IT and business transformation journey, the health and beauty retailer sought to modernize its core back-office systems for finance and human resources. They partnered with SkillNet to handle these critical back-office integrations and streamline operations.

In today’s digital age, outdated systems from previous decades are no longer sufficient. The client decided to address this challenge by updating their key back-office systems. They aimed to achieve high data reliability and reduce manual interventions while ensuring timely reporting on errors and exceptions.

  • Operational Inefficiencies: Manual interventions were needed for scalability, failure management, and exception handling.
  • Slow Response Times: Diagnosing and fixing issues took longer, leading to business disruptions.
  • Limited Visibility: Difficulties in foreseeing and managing system issues.
  • High Deployment Costs: Each new build incurred additional expenses.
  • Constant Expenses: Ongoing costs regardless of actual system usage.
