Now is the time to select the most suitable travel companion for your transformation journey.
Tietoevry boosts your S/4HANA journey and by applying the GoField method, ensures the following:
The objective is a future-proof ERP architecture. First, you define which functions will be included in S/4HANA, and which will be obtained through other systems.
The S/4HANA roadmap includes a phased transfer, comprising several smaller projects, from the existing SAP ERP to the desired S/4HANA system. At the same time, you build systems outside S/4HANA. These projects need to be started in time. Together with SAP S/4HANA, external systems often bring clear business benefits, and it makes sense to seek them out as soon as possible.
Perhaps the most important step in the GoField method is getting started. The first step, where you roughly define the 1) current situation, 2) the desired ERP architecture, and 3) create the roadmap in four calendar weeks. The fixed duration ensures that the first step will actually be taken, and the project will get launched.
The desired ERP architecture must support future business needs. When making decisions on ERP architecture, it is important to understand:
It is often necessary to make changes in both directions in comparison to the current situation. SAP has added functionalities from traditional satellite systems (such as APO, SRM, CRM) to S/4HANA. And, on the other hand, there are cloud-based solutions from SAP and other system providers available for an increasing number of business capabilities. The most important border area business capabilities are:
Border area business capabilities are essential from the point of view of integrations. Different satellite systems (often cloud-based), and S/4HANA as the core, have specific domains. And a rough integration architecture is designed between them.
A capability honeycomb roughly describes the functionalities to be included in S/4HANA (dark blue), the functions that clearly belong outside S/4HANA (white), and functions that need to be analysed on a client-specific basis and are subject to an architecture decision (light blue).
The way in which you switch to S/4HANA is one of the most important decisions in the roadmap. The main options are Greenfield, Bluefield and Brownfield. Usually, Bluefield is the most suitable way to migrate.
One of the core objectives of the road map is to find a balance between the rapid and agile development required by business, and the fairly extensive IT system upgrade required by migration to S/4HANA. The balancing is done using three swim lines.
When the ERP architecture has been defined at the beginning and the roles of the various systems are understood, development can be done in a parallel manner.
The first and perhaps most important step in the GoField method is getting started. You roughly analyse the current situation, plan the desired objective and ERP architecture, and create the roadmap during a period of four weeks.
The end result provides the starting point for decision-making and more detailed planning of the S/4HANA project. As well as for possible competitive tendering.
