The Evolving Debate on Customization vs. Standardization

The debate over customization versus standardization in SAP implementations has been a central discussion within the SAP ecosystem for decades.

In the early days, the focus was heavily toward customization, as organizations sought to tailor their SAP systems to fit perfectly with their specific business processes.

This era was marked by extensive use of custom solutions that addressed specific requirements, leading to highly complex systems deeply integrated into the organization’s operations.

In the mid-2000s SAP began to emphasize the value of adopting best practices through standardized processes, offering pre-configured industry solutions that promised to reduce implementation times, lower costs, and simplify maintenance.

This shift was accelerated by the introduction of SAP S/4HANA and the growing emphasis on cloud-based solutions, which favored standardization as a means of supporting scalability.

Today, the debate has evolved into a more nuanced discussion.

The key question is no longer whether to customize or standardize but rather how to strike the right balance between the two, with “standardized customizations” using SAP BTP. This balance is crucial for ensuring that SAP systems remain agile, cost-effective, and capable of supporting the organization’s strategic goals over the long-term.

This IgniteSAP article will give a brief overview of what SAP consultants must consider around the extremely important issue of how to guide customers: and achieve the right balance between creating bespoke systems that meet specific needs, and making maintenance, upgradability, and scalability easier in the long-term.

The Case for Standardization in SAP Implementations

Standardization offers several compelling advantages, particularly in the current landscape where agility and cost management are highly valued.

With standardized processes, organizations can significantly reduce their TCO.

This is primarily because standardized systems have lower implementation costs, easier maintenance, and more straightforward upgrades. The reduced need for custom code means that organizations can more easily apply SAP’s regular updates and enhancements without the risk of breaking custom integrations or requiring extensive re-testing.

Standardized systems also align closely with SAP’s support framework and the broader ecosystem of third-party solutions. This ensures that organizations can leverage SAP’s full range of support services and take advantage of the network of SAP-certified solutions and partners.

In an era where cloud integration is becoming increasingly important, standardized systems also facilitate smoother transitions to cloud-based platforms like SAP S/4HANA Cloud, which are less tolerant of extensive customizations.

SAP’s push towards a "clean core” is part of this standardization initiative. The clean core philosophy keeps the core ERP system free from custom code, using SAP’s Business Technology Platform (BTP) or other external platforms for any necessary customizations or extensions. This also enhances system performance and security by minimizing the risks associated with custom development.

While the benefits are clear, it is not a one-size-fits-all solution. The nature of an organization’s business, its competitive environment, and its strategic objectives all play a critical role in determining whether standardization alone can meet its needs.

The Case for Customization in SAP Implementations

For organizations operating in highly competitive or specialized industries, the ability to differentiate through unique business processes is often a key factor in achieving and maintaining a competitive edge. In such cases, customization allows companies to make sure their SAP systems to support these unique processes, so the software aligns perfectly with the way they do business.

Customization is also essential when integrating SAP with legacy systems or non-standard software environments. Many organizations, particularly those with long histories of IT development, have built up complex ecosystems of applications that SAP must interact with. Custom solutions are often required to ensure integration, enabling data to flow smoothly between SAP and other critical systems.

Enhancing user experience through customization can be a powerful driver of user adoption and satisfaction. Using bespoke interfaces, workflows, and reporting tools for the specific needs of different user groups, organizations can create a more intuitive and effective working environment.

However, the decision to customize should not be taken lightly, as customizations add layers of complexity to the system. Each piece of custom code represents a potential point of failure, requiring careful management and ongoing support.

Over time, extensive customization can lead to technical debt, where the system becomes so complex that it is difficult to update or modify without significant risk and expense.

Given these risks, it is essential to carefully evaluate when customization is truly necessary. This requires considering the immediate benefits, but also weighing the long-term implications for system maintenance, upgradability, and overall agility.

Emerging Trends and Future Directions

The balance of SAP customization and standardization is being reshaped by emerging technologies such as AI, machine learning, IoT, and blockchain. These technologies are increasingly being integrated into SAP’s offerings, opening up new possibilities for both standardization and customization.

AI and machine learning are being used to enhance predictive analytics, automate routine tasks, and optimize business processes in real-time. While these technologies are often embedded within SAP’s standard solutions, they also provide opportunities for customization. Organizations can develop custom algorithms or machine learning models tailored to their specific needs, enabling them to extract unique insights and drive innovation.

IoT and blockchain technologies are expanding the potential for customization, particularly in manufacturing, logistics, and supply chain management. Custom solutions that integrate IoT sensors or blockchain-based smart contracts can provide greater levels of visibility, security, and efficiency, allowing organizations to optimize their operations in ways that standard solutions may not fully support.

The challenge for SAP consultants is to ensure that customization efforts around new technologies do not undermine the benefits of standardization.

SAP’s Business Technology Platform (BTP) offers tools and services that allow organizations to build custom applications and extensions without modifying the core ERP system. By leveraging the modularity of BTP, organizations can achieve a balance between innovation and stability, ensuring that their custom solutions are scalable, maintainable, and compatible with SAP’s ongoing updates.

Best practices for using BTP for customization include adopting a low-code/no-code approach where possible, which allows for rapid development and deployment of custom solutions with minimal disruption to the core system. API integrations should also be carefully managed so that custom applications can interact easily with SAP’s standard processes without introducing unnecessary complexity or risk.

Choosing Between Customization vs. Standardization

Guiding SAP consulting clients through the decision of whether to customize, standardize, or combine both, is one of the most important aspects of an implementation project.

The first step in this process is conducting requirements gathering and a fit-gap analysis, which identifies where the client’s business needs align with SAP’s standard processes, and where gaps exist that might require customization. This analysis should be thorough, considering not only the immediate functional requirements but also the long-term implications for system maintenance, scalability, and upgradability.

The next step is to prioritize customization based on business value.

Not all gaps identified in the fit-gap analysis necessarily warrant customization. In many cases, it may be more beneficial to adapt business processes to fit standard SAP functionality. Customization should be reserved for areas where it will deliver significant strategic value, such as enhancing competitive differentiation, meeting unique regulatory requirements, or enabling innovative business models.

The final step is to communicate the benefits and drawbacks of both approaches to the client. This involves explaining the technical and financial implications but also helping the client understand the strategic trade-offs involved. For example, while customization might offer a perfect fit for current processes, it could limit the organization’s ability to adapt to future changes or upgrades. Conversely, while standardization might require some process changes or compromises, it provides a more stable and agile foundation for the future. Where possible, explanations should translate these complexities into monetary terms in order to make the business impact clear.

The Knowledge and Experience to Guide Clients

To effectively support both customization and standardization, SAP consultants must develop a deep and broad set of skills.

This begins with mastering SAP’s best practices and standard processes, which form the foundation of any implementation. Consultants should continually update their knowledge through SAP’s training programs, certifications, and by staying informed about the latest developments in SAP’s product offerings.

Consultants must also develop a deep understanding of the industries in which their clients operate. This is crucial for making informed decisions about when customization is necessary. Understanding the competitive landscape, regulatory environment, and common business practices within the client’s industry allows consultants to offer more relevant and strategic advice.

Technical skills are also essential, particularly in the areas of SAP BTP and custom development. Proficiency in BTP services enables consultants to design and implement custom solutions that enhance the standard SAP system without compromising its integrity. Familiarity with SAP’s ABAP programming language and other development tools is also important for creating and maintaining custom code when necessary.

Finally, consultants must also be transparent about the potential risks and benefits of each approach, and avoiding over-engineering solutions that benefit the consultancy more than the client. The goal should always be to recommend the best approach for the client’s specific needs, even if it means sacrificing short-term gains for long-term sustainability.

Achieving the Right Balance for Long-Term Success

As new technologies emerge and are adopted in the SAP ecosystem, the debate between customization and standardization continues to evolve.

While standardization offers clear advantages in terms of cost efficiency, ease of maintenance, and alignment with SAP’s evolving ecosystem, customization remains essential for organizations that require unique solutions to maintain their competitive edge.

The key to success lies in finding the right balance between these two approaches for each customer.

SAP consultants need to understand the implications of their work so they can be more effective in guiding clients through this process, helping them make informed decisions that meet their strategic goals while ensuring that their SAP systems remain agile, scalable, and future-proof.

As SAP continues to develop, the ability to navigate this debate will become increasingly important. The current consensus appears to recommend “standardized customization” around a clean core, with SAP BTP and other third-party solutions certified by SAP.

This is a complicated and continually shifting area of SAP consulting, but it represents an opportunity for practitioners: in developing a deep understanding of SAP’s offerings, industry-specific needs, and the strategic implications of customization, consultants can become more valuable as partners in their clients’ digital transformation journeys.
