Hellenic Cables is a company positioned at the forefront of high growth sectors, such as energy and telecommunications. In response to its growing scale of operations and the need to standardize processes, Hellenic Cables launched a comprehensive modernization and digitalization program for its production processes. 

The program included: 

• the implementation of an MES system, delivered by an external vendor, 

• the development of a consistent integration layer between SAP ECC and the MES system, 

• the centralization of production data and master data, 

• the standardization of processes across the entire group. 

Project complexity 

BlueSoft was invited to join the program as the partner responsible for designing and implementing the integration layer, which was intended to become the foundation of the new IT ecosystem. Integrations were one of the key components of the MES implementation, ensuring that data in SAP and the MES system remained consistent, complete, and available in near real time. 

Key challenges and constraints 

At the start of the project, the organization faced several challenges: 

• the lack of a unified integration standard between SAP and the MES system, 

• manual and inefficient data transfer processes, 

• the risk of errors and limited traceability, 

• insufficient automation of production processes, 

• fragmented data spread across multiple systems, 

• the need to develop a solution that could be easily reused by other companies within the group. 

Project objectives 

Hellenic Cables expected a solution that would provide: 

• full automation of key data flows, 

• near real-time response to production events, 

• a unified integration standard that could be applied by other entities within the group, 

• a shared and scalable architecture to support future expansion, 

• maximum reduction of manual work and operational risk, 

• ensured data integrity and high data quality throughout the entire production process. 

The project was strategic and became the foundation for the group’s digital transformation.

BlueSoft delivered a comprehensive integration layer based on the MuleSoft Anypoint Platform, working closely with the MES implementation team and Hellenic Cables business stakeholders. The solution was designed as a key component of the new IT ecosystem, supporting both the MES implementation and the organization’s long-term development. 

BlueSoft’s role in the program 

As part of the integrated implementation program, BlueSoft was responsible for: 

• designing and implementing the complete integration architecture, 

• closely collaborating with the MES implementation team to align the MES deployment with the integration work, 

• ensuring consistency across implementation and integration processes, 

• building an integration platform ready to scale across Cenergy Holdings. 

Project approach 

The project was delivered using an Agile methodology, with an iterative approach, full transparency, and close cooperation with the client at every stage. 

The work was divided into two main streams: 

• Pattern 1 – Master Data 

• Pattern 2 – Production Operations 

The scope covered the full integration lifecycle: 

Design → Development → Integration Testing → Performance / Load Testing → UAT → Go Live → Hypercare 

As part of the program, several dozen integrations were designed and implemented in line with API-led connectivity standards. 

Reusability as a key outcome 

One of the main objectives of the program was to build an integration platform that could be reused across Cenergy Holdings, without the need to develop integrations from scratch. 

BlueSoft designed the MuleSoft APIs to be: 

• sufficiently generic, 

• based on shared and standardized principles, 

• easy to extend as the organization evolves, 

• independent of the specific characteristics of a given production plant, 

• fully reusable in future MES implementations across additional factories. 

With this approach, the integration platform became a practical enabler of growth, significantly reducing the time and cost required to integrate new companies into the group’s shared processes and systems.rship with access to expert knowledge.
