How can complex IT structures be transferred and streamlined into a harmonized system landscape? In order to optimize its own business processes and increase agility, EDEKA DIGITAL – the subsidiary of the EDEKA head office for digital change – put an ambitious transformation project with a small go-live screen on the corporate agenda. Implementation: Successful!
Nationwide, 3,800 self-employed merchants, seven regional wholesale dealers and a head office that controls the national commodity trade: The EDEKA network, which achieved a turnover of 51.9 billion euros in 2017 with 11,430 stores, is characterized by a cooperative profile. Indeed, a complex starting position when it comes to establishing integrated IT structures and reducing the amount of system landscapes.
The challenge: Unifying systems
The key challenge was to standardize historically grown FI systems (financial systems) with different master data, functionalities and processes requiring as little downtime as possible. Among other things, all company codes were to be mapped in a single financial system with a data basis, structures, reports, etc. as homogenous as possible. In order to keep IT costs in product management, projects and further developments low in the future, interfaces, self-written programs within the SAP system (so-called Z programs) and software adaptations to the requirements of the 2,000 users – the „customizing“ – had to be consistently optimized.
The Solution: Transformation and Migration within 11 Months
EDEKA DIGITAL implemented the project – from project start to go-live – within 11 months. The team was advised and supported by experts from the software and consulting company SNP Schneider-Neureither & Partner SE in Heidelberg. With the help of an IT solution called Transformation Backbone with SAP LT, EDEKA DIGITAL was able to transfer historical application data into the target system, as well as reorganize and harmonize it. In addition, a standardized chart of accounts was introduced. Application customization is now controlled centrally via a software that the EDEKA team was able to use on its own after only a short training session.
For the go-live, there was a time frame of only 76 hours including business downtime. The basis for the successful execution was a detailed cut-over plan, which was optimized with the help of test migrations and go-live simulations.
