Client
A leading water supply and treatment utility company headquartered in the United Kingdom provides essential water and wastewater services with a production output of 1.3 Gigalitres/day (drinking) and 1.0 Gigalitres/day (recycled).
Challenge
The client ran its Finance and Supply Chain Operations in SAP ECC and later migrated to S/4 HANA for Central Finance, Financial Accounting and Cost Controlling (FICO), Materials Management, Sales and Distribution, and Production Planning.
With a user base of 3000+ employees, the client faced performance issues in processing high volumes of transactions and was constrained by a complex procurement experience. Additionally, manual testing when rolling out applications led to unforeseen delays. To streamline efficiencies, the client needed to ensure the following:
- Minimize the invoice generation time
- Improve application performance for processing high volumes of transactions
- Increase spends visibility and control for procurement
- Reduce onboarding time for new joiners and user inquiries on payroll
Solution
Hexaware took stock and proposed a best-fit best-practices solution that involved:
S/4 HANA Enhancements & Database Migration
Due to the slow performance in processing/transacting high volumes for a user base of 3000+, Hexaware decided to migrate the client’s application database from HANA 1.0 to HANA 2.0 and automated invoice generation from device-based reading, resulting in a 68% reduction in bill processing cycle time.
Procurement Transformation
With distribution systems in place and no single source of truth, the procurement experience needed to be re-engineered completely. Hexaware analyzed the business processes in detail and created a uniform platform to search for goods & services using Ariba, IBP & Fiori, augmenting supply chain efficiency by 20% for wastewater management.
SuccessFactors Support
On the Human Capital Management (HCM) front, there were several user inquiries on payroll and candidate onboarding. Hexaware performed end-to-end managed services for SuccessFactors, covering Payroll, Recruitment, Candidate Onboarding, and Learning. This shortened the onboarding process for new joiners by 50% and enabled speedier resolution of user tickets by providing 24/7 payroll support.
Automation in Functional Validations/Testing
Hexaware implemented complete automation of all regression test scripts using its proprietary test automation pack, reducing the time required for global application rollouts by 25%.
Benefits
The client achieved exceptional results with Hexaware’s contribution for migrating the client’s application database from S/4 HANA 1.0 to HANA 2.0. Some of the significant benefits realized include:
- 68% reduction in the bill processing cycle time
- 20% augmentation in supply chain efficiency for wastewater management
- 50% faster onboarding for new joiners
- 25% reduction in the time needed for global application rollouts
