With Oracle and SAP announcing they will phase out standard support for older versions of their enterprise resource planning (ERP) suites over the next few years, executives whose businesses run on these systems are taking advantage of the moment to reevaluate their ERP programs. Many of these companies struggle with their inflexible and monolithic ERP systems, the result of years of customization and M&A activity that forced them to cobble together different systems from acquired companies. These complex ERP systems help run organizations (see Figure 1), but they do a poor job supporting companies’ aspirations to develop nimbler ways of working and unlock the benefits of digitalization and cloud computing.
ERP systems manage core operational business processes
What most companies need instead are flexible systems that allow them to respond rapidly to customer needs and new opportunities in an increasingly competitive environment. These next generation, modern ERP systems are likely to have a smaller core of critical business processes (such as transaction management and tracking), with lightweight connections to more specific functional and industry applications that live on the cloud, including third-party solutions such as Workday for human resources and Salesforce.com for customer relationship management (see Figure 2). By maintaining their connections to the legacy systems that keep the company running and deploying flexible microservices, modern ERP systems can help companies achieve a competitive advantage.
Modern architectures are likely to have a smaller ERP core supported by best-of-breed, third-party SaaS solutions
Today, most ERP systems run on-premise or on a private cloud. Increasingly, companies will want to become more comfortable working with cloud-hosted systems. Since the cloud makes it easier for vendors to deploy rapidly evolving technologies—such as machine learning, the Internet of Things, artificial intelligence and data analytics—and stay current with updates, cloud systems are likely to dominate in the future. As they do, ERP will evolve from providing mere efficiency to delivering valuable insights and ensuring predictability. It won’t happen overnight: many third-party solutions will take time to mature, and customers are likely to sweat out their investments in current systems. But since the transition seems inevitable, executives can begin to evaluate their options by considering several key issues (see Figure 3).
Before embarking on an ERP modernization journey, companies need to make key decisions that will affect future flexibility and costs
Build or buy? As executives think about their ERP upgrade path, the most critical questions include how to choose a configuration that supports their strategic goals, as well as the level of investment and the appetite for risk. Some leading companies may decide there is a competitive advantage in developing a bespoke ERP solution, as Amazon and Tesla have done. This is an expensive and disruptive option, although it does allow for total customization and freedom from external vendors. Most companies, however, will choose to purchase an off-the-shelf core ERP system to benefit from the ERP vendor’s experience, while also investing in some level of customization and third-party solutions for specific functions or industries.
Early adopter or fast follower? Another critical question is whether to embrace new technologies for the competitive edge they might offer, or to wait and benefit from the experience of others. Early adopters are typically smaller, more disruptive players who can tap certain advantages by developing the system with the ERP vendor, or an industry solution with a third-party vendor. They might gain an edge, but they must have the patience and ability to work with the vendor to improve the system. Larger companies with less appetite for risk are more likely to be fast followers, letting others work out the bugs and then investing in a more fully baked product. This pattern may be more cost-effective, but it also risks lagging behind fast movers while waiting for the ideal solution.
Upgrade only or rationalize? Companies whose ERP systems result from accretive M&A activity can decide to continue on this path and still gain the benefits of technical upgrades—a reasonable option for companies that can tolerate a complex ERP architecture. However, most organizations can gain more by rationalizing and consolidating their multiple systems into one. This may be more expensive and disruptive in the short term, but it is likely to deliver greater benefits over time, including lower maintenance costs, better data quality and integrated reporting across the entire business. Eventually, every company will need to make this transition. The longer they put it off, the greater the pressure to ensure a flawless implementation.
Brownfield or greenfield? A closely related decision is whether to continue upgrading or to deploy a new ERP solution. A brownfield approach is cheaper and less disruptive and may be appropriate for less complex ERP instances where minimal changes are required. But a greenfield approach may be worth the investment for companies with highly complex or customized processes that could benefit from complete redefinition. Many executives see this moment as a once-in-a-generation opportunity to invest in a more robust and adaptable solution that will allow the company to operate more nimbly. The decision to commit at this level remains a difficult one, but executives should make it based on how much the business depends on its ERP system.
On-premise or cloud? A range of hosting options are available, and executive teams should make their decisions based on their broader IT strategy and the importance of their ERP systems. The simple answer is that companies should move more of their operational systems to the cloud. But the reality is that most have so many existing applications, with such a large investment in existing, on-premise licensed software, that cloud migration will take many years—and, in fact, some legacy apps that just do their job quietly in the background should stay on-premise. ERP vendors can help by building bridges that encourage companies to migrate their workloads to the cloud. As these systems are increasingly cloud-based, with integral connections to other cloud-based applications and data sources, customers will find it easier and more reassuring to move more of their workload to the cloud. Companies that fail to make the most of these cloud connections are depriving themselves of access to the best-of-breed solutions that could give them a competitive edge.
Better performance through modern ERP
Armed with the answers to these questions, executives can begin to put in place a plan to modernize their ERP systems and transform their organizations. The experience of leaders who have undertaken this transformation shows that the effort can deliver significant gains, including better access to data, more efficient use of resources and reduced operating expenses.
For example, a large industrial company with global operations was seeking to improve its performance by transforming its management of financial transactions. A key component was improving the connections between its core ERP system and new sources of data, internal and external, in order to deliver sharper insights that could improve decision making. A side benefit was that by improving the system’s access to automated data flows, the company substantially reduced the amount of time it spent gathering data—freeing up resources that it shifted to data analysis that boosted the organization’s financial intelligence.
In another case, a large international financial services institution, active in retail and corporate banking services, implemented a modern technology stack supporting its processes across all business units. The core ERP environment strengthened the entire organization, enabling a consistent approach for data and analytics, customer experience and technology management. These technology principles served as “guardrails” that enabled the individual business units to release new services and functionality quickly to their customers. Modernizing the technology stack with an open and flexible ERP core, while consolidating and rationalizing the number of systems, significantly reduced costs and improved the customer experience by deploying consistent and complete data and advanced analytics.
Reducing risk of the transformation
Finally, among the greatest barriers to improving ERP systems are the scars that executive teams bear from previous upgrade efforts. Most ERP upgrade projects fail to deliver at least some of their goals, and many executives are hesitant to invest time and resources in an endeavour with such long odds for success.
There are, however, strategies to help executives reduce the risk of deployment—not only of the ERP platform itself, but also its connections and integration with other essential applications and operations.
- Create a compelling business case (both monetary and nonmonetary) to generate a pull from the business rather than a push from IT.
- Learn from the tech industry’s best practices and adapt your process to those, rather than change the technology to support your process.
- Be very clear on the scope of the modern ERP core and understand that one platform will not support all business processes, end to end.
- Migrate the elements first that create the most business sense and value, but do not lose sight of the potential integration challenges and benefits.
- Manage and prioritize this effort as one of your most important business initiatives, with CEO sponsorship and active involvement of all the organization’s businesses.
No transformation of this scale can ever be easy. However, by answering questions about the scope and nature of the upgrade, and by adhering to some simple and practical strategic guidelines, executives can manage the risks of modernizing their ERP systems to gain maximum competitive advantage in a more connected world.
