Key Phases of SAP Greenfield Implementation
The SAP Activate methodology provides a structured framework for successful SAP Greenfield implementations. This methodology includes several key phases, each designed to guide the organization through the implementation process systematically. Here’s a closer look at each one.
Prepare Phase
The Prepare phase is the foundation of the Greenfield implementation process. It begins with a feasibility study to evaluate the proposed SAP solution’s fit for the business requirements and its overall feasibility. This phase also involves creating the project charter, which outlines the project’s objectives and identifies key stakeholders. Additionally, a risk assessment report is developed to identify potential risks and mitigation strategies and establish clear objectives and potential risks.
This phase defines the project scope and implementation strategy, ensuring that the organization has a clear roadmap for successfully implementing the implementation project and the project’s objectives in project management.
Using pre-configured templates can also streamline this process, providing a defined starting point for the implementation. Developing a comprehensive project schedule and phased roll-out plan is also critical to the Prepare phase, ensuring all stakeholders are aligned and prepared for the journey ahead.
Discover Phase
In the Discover phase, a detailed analysis of the existing SAP ERP system is conducted to identify gaps between the organization’s requirements and SAP’s core capabilities. A requirements specification document outlines the project needs and ensures that all requirements are documented and understood. This phase also involves defining and reviewing backlog items and delta requirements during workshops.
Additionally, fit-to-standard workshops are crucial in the Discover phase, where Business Process Experts execute scenarios in the starter system to create a proof of concept. These workshops help refine the project scope and ensure the proposed solution aligns with the organization’s existing business processes and system conversion.
Explore Phase
The Explore phase focuses on validating concepts and aligning them with business needs through prototyping. Prototyping allows for testing and refining business processes before full implementation, ensuring the solution meets the organization’s requirements. Business Driven Configuration Questionnaires are used as a key reference during workshops to identify backlog items and requirements.
During this phase, the project team reviews and consolidates backlog items to determine the scope of the implementation phase. In this phase, project teams also refine the implementation strategy and update the project schedule to reflect any changes.
This phase is a significant undertaking crucial for ensuring that all aspects of the implementation are aligned with the organization’s business objectives and that any potential issues are identified and addressed early in the process.
Realize Phase
The Realize phase is where the bulk of the configuration and development activities take place. This phase involves performing configuration activities based on the requirements identified in the Explore phase. Teams also design, develop, configure, and test core SAP solutions in this phase.
Key deliverables produced during the Realize phase include the configured SAP system, custom code, integration documentation, test results, data migration results, and system configuration. Configuration is transported from the Development system to the Quality system for thorough testing, ensuring all elements work correctly before going live.
Deploy Phase
The Deploy phase is where the final user training and data migration occurs after the system setup is complete. This phase ensures that all users are adequately trained and your data is accurately migrated to the new system. The SAP Activate methodology plays a crucial role in guiding the deploying SAP software process, ensuring a seamless transition to the new system.
Run Phase
The Run phase focuses on post-implementation support, which is critical for incident management and enhancing system performance. Promptly managing incidents ensures that any issues are resolved quickly, maintaining system integrity and user confidence.
Ongoing system performance evaluation contributes to continuous improvement, allowing for the adaptation and optimization of processes. This phase ensures that the existing system continues to meet the organization’s business objectives and evolves with changing business needs, including implementing a new system and an ERP system.
Challenges in Greenfield Implementations
One significant challenge is the need for new data migration methods, as existing legacy data must be transformed and uploaded into the new SAP S/4HANA system. This process requires ensuring that data is clean, accurate, and properly mapped while retaining necessary historical data. Additionally, security concerns differ from previous systems and must be addressed during the migration to SAP S/4HANA.
Extensive change management is required due to the extensive changes for users during the Greenfield implementation. Efficient change management is crucial when migrating in phases, as each transition impacts both the legacy and new systems. User adoption and engagement are critical to the success of an SAP S/4HANA implementation, and maintaining updated access controls is essential as new security roles emerge with S/4HANA.
