Project Overview

This project was delivered for a defense manufacturing company and was based on the D4S product (Accenture). The goal was to implement a reliable cost tracking system where production costs are calculated directly from the actual time spent by people and assets on each manufactured item.

In the defense industry, pricing and funding depend on accurate, auditable reporting of production effort. That makes time allocation to production orders a core business requirement — not just an internal KPI.

Business Value

The solution ensured accurate and compliant cost reporting by connecting SAP production data with a controlled time allocation process, and then feeding validated cost allocations back into SAP.

Key outcomes:

• Reliable, traceable allocation of labor time to produced goods

• Improved funding and pricing accuracy through complete time reporting

• Clear separation of billable vs. non-billable work across internal projects

• Higher data quality through reminders and completeness checks

• Secure on-premises deployment aligned with defense industry requirements

What We Built / Solution

SAP Production Order-Based Time Allocation

• Import of production orders and production steps from SAP via the D4S interface

• A user application where each worker could assign time spent to:

  • specific production orders

  • specific production steps

  • specific finished goods

Non-Billable Hours and Internal Projects

• Support for assigning non-billable hours to internal project buckets

• Full cost transparency across production and overhead activities

Bidirectional SAP Integration

• Production structure data coming from SAP into the application

• Cost allocation and time assignment data reported back to SAP for financial and controlling processes

Attendance System Integration and Completeness Control

• Integration with the attendance tracking system to determine how many hours each worker must allocate per day

• Automated completeness checks to detect missing assignments

• Reminder mechanism prompting workers when time entries were incomplete

---

Architecture Highlights

• Deployed on-premises in the client environment using Kubernetes (critical for defense industry constraints)

• Designed for stable operations, auditability, and secure integration flows

• Clear separation of integration, business logic, and user-facing workflows
