What is Greenfield Approach

The Greenfield approach involves implementing SAP S/4HANA in a fresh and independent environment, starting from scratch without any existing legacy systems. This approach allows organizations to build a new system tailored to their specific requirements, leveraging the latest functionalities and best practices offered by SAP S/4HANA. Here are some key points to consider:

Flexibility and Agility

Resource Intensive

The Greenfield approach requires substantial investment in terms of time, resources, and budget. Organizations need to carefully plan and execute the implementation, considering factors such as infrastructure, data migration, and user adoption.

Brownfield Approach - system conversion

The brownfield approach, or upgrade approach, is a database migration and application conversion. It is ideal for organizations using legacy systems, such as SAP R/3 or ECC, and are satisfied with existing data management and business processes but require quicker adoption and innovation.

This approach enables migration from SAP ECC to S/4HANA by converting an existing SAP environment without reimplementing or disrupting current business processes. While a Brownfield project carries the risk of potential technical issues during and after the conversion, SAP offers dedicated conversion tools and guidelines designed to proactively address and minimize such problems from the outset.

While a Greenfield approach represents a complete reengineering of your SAP ERP, a Brownfield approach is more like an upgrade.

Using the Brownfield approach, you can get SAP S/4HANA up and running, and at the same time, migrate your existing SAP workflows and systems over to the newest version of SAP S/4HANA.

You also can keep your proven business processes as well as the customizations you’ve been using to manage your data since you don’t have to move everything over. The Brownfield approach lets you reevaluate and edit your existing processes and port over the ones that are working.

The main advantage of Brownfield is that there is usually a shorter project runtime, and therefore there’s less disruption to your business. A Brownfield approach lets you migrate to SAP S/4HANA without a new implementation and disruption of existing processes, building on existing elements of the SAP landscape, such as interfaces to suppliers and partners.

Still, Brownfield has its disadvantages. Because you’re basically porting over everything from your previous SAP ERP, it’s often seen as stifling innovation. The success of the Brownfield implementation centers around how well your existing workflows and systems are replicated.

Because of all the complexities that come with porting over customization and workflows, a Brownfield implementation is best-done on-premise. Brownfield is best suited for customers who are looking to continue using their current solutions and want to rapidly convert from SAP ECC to SAP S/4HANA.

The most common advantages of SAP Brownfield Deployment are:

Faster deployments with shorter timelines
Minimal business change impact and process disruption
Enables re-evaluation of previous customization and existing process flows
Supports selective picking of components during ECC version to SAP S/4 HANA platform
