Things to do before an SAP S/4HANA System Conversion

Digital Maps Jun 9, 2023

The phrase “Readiness Assessment” is resonating across the SAP ecosystem. Organizations on SAP ECC are taking up readiness assessments to get a complete understanding of their ECC system and plot their risk-free path to S/4HANA.

This is primarily because they understand that SAP S/4HANA will :

  • Improve operational efficiency by removing aggregate tables and rigid data structures
  • Provide instant information and real-time insights by removing batch jobs and manual effort
  • Provide a virtual data model that offers informational analytics with a combination of transactional and operational data
  • Offer a future-ready platform for innovations and R&D
  • Simplify the IT landscape to minimize operational costs and capital expenses
  • Provide an intuitive and modern user interface and user experience
  • Act as the “digital core” for the “intelligent enterprise”

What you should know is that moving from SAP ECC to SAP S/4HANA is not like a typical EHP upgrade. It requires a deep understanding of the business structure, business implications, technical & functional impacts, business strategies, executive strategies, and updated skillsets. In addition, a thorough understanding of the required effort and expenditure is needed as well.

In such a situation, how can you get the other stakeholders on board?
The answer is building a business case and discovering the path to S/4HANA through a comprehensive readiness assessment.

The First Step – Building the Business Case

Build Early

  • Building a coherent business case is critical for any SAP ECC to SAP S/4HANA transition. Also, it is important to start building the business case well ahead of the move – at least a year in advance.
  • Waiting till the last minute is a recipe for disaster as you will have to pay the cost of indecision, higher prices for S/4HANA licenses, market share loss to the competition, and a rushed S/4HANA transition which carries a high risk for failure.

Be clear on your Objective

  • While building the business case for S/4HANA, focus on where you are going and what you will get by going there. Focus beyond savings to understand the innovation, understand the value, and the business and IT benefits.
  • You can make a good start by referring to the SAP Value Advisor Tool and the SAP Business Scenario Recommendations Tool to identify the specific areas of your business you can transform.
  • You can also look at the success stories & use cases of other organizations in your industry, and network with your industry peers & SAP experts to try and draw examples from them to build your business case.

Moving Forward – Readiness Assessment and Beyond

A readiness assessment is a process that helps businesses evaluate their preparedness for implementing a new technology or solution. A Ktern.AI readiness assessment might involve evaluating a business's current infrastructure, processes, and systems to determine whether they are capable of supporting the implementation of an AI solution.

During a readiness assessment, Ktern.AI might consider factors such as the business's IT infrastructure, data quality and availability, and the availability of skilled personnel to implement and maintain the AI solution. The assessment might also consider the business's goals and objectives, as well as any potential challenges or risks that might arise during the implementation process.

After completing the assessment, Ktern.AI would provide recommendations and a plan for implementing the AI solution. This might include recommendations for any necessary infrastructure upgrades or changes to processes and systems, as well as a timeline and budget for implementing the solution.

Once you define your business case, you will soon realize that there is a huge path ahead. System conversion projects require a lot of planning and in-depth inputs from technical, functional, and business stakeholders. But, don’t worry too much and start stressing over it to a point of absolute mental breakdown. Stop worrying too much about the potholes and start preparing for your journey. After all, there is a blissful destination at the end of the journey.

But, how can you ensure the right budget, effort, expertise, man-hours, project plan preparation, and project execution?

The answer lies in your SAP ECC system. This is because the “to-be” state of your S/4HANA system is directly dependent on the “as-is” state of your ECC system. But, how do you get the answer? You get the answer by completing a comprehensive readiness assessment or study of your SAP ECC system, preferably with KTern.
