Despite recent advancements like AI and more integrated supply chain systems, a surprisingly large number of Fortune 500 companies still rely on legacy systems—outdated software or hardware that continues to serve critical business functions.
Companies like American Express, which still uses old COBOL systems for banking; Delta Airlines, which depends on a system from the 1960s to manage flights; and Walmart, which uses a mainframe system for inventory and sales, are just a few examples.
Before we can understand why Fortune 500 companies cling to old systems, we first need to explore the challenges they face by relying on them—and why it's so surprising they haven't upgraded yet.
What Challenges Are Imposed with Legacy Systems?
Legacy systems, often decades old, are deeply embedded in the operational frameworks of many large corporations. These systems, which include outdated software and hardware platforms, can present several significant challenges:
Maintenance and Support:
Many legacy systems are no longer supported by their original developers.
For instance, IBM's AS/400 (which launched in the late 1980s) is still in use in various industries despite IBM discontinuing its support.
This lack of support means companies often rely on in-house expertise or third-party vendors, which can be costly and risky.
Integration Issues:
Modern businesses require systems that can easily integrate with new technologies.
Legacy systems often lack compatibility with contemporary software solutions, leading to fragmented workflows and data silos.
A prime example is the COBOL-based systems used by many banks; while robust and reliable, these systems struggle to interface with modern applications and platforms.
Security Vulnerabilities:
Older systems are more susceptible to security breaches.
According to a 2020 report by Cybersecurity Ventures, cybercrime damages will cost the world $6 trillion annually by 2021.
Legacy systems often lack the latest security updates, making them prime targets for cyberattacks.
High Operational Costs:
Operating legacy systems can be expensive. According to a study by the Ponemon Institute, the average cost of maintaining legacy systems can be up to 70-80% of an organization's IT budget.
These costs include hardware maintenance, software updates, and the salaries of specialized staff needed to keep these systems running.
What Opportunities Do Companies Miss by Using Legacy Systems?
Using outdated systems can cause companies to miss out on innovation, efficiency, and staying competitive.
For example:
American Express still uses old COBOL systems for banking, which slows their ability to keep up with modern financial tech. This limits their ability to create new, customer-friendly services that fintech startups can offer easily.
Delta Airlines also relies on an old IBM system from the 1960s to manage flight reservations and schedules. This makes it harder for them to improve customer service and run operations more smoothly in real-time.
Walmart's outdated mainframe system for managing inventory and sales means they can't fully take advantage of new tools like AI and advanced analytics that could streamline their supply chain and help with decision-making.
Even the New York Stock Exchange still uses old IT systems, which prevents them from adopting cutting-edge technologies like blockchain and AI for trading. As a result, they can’t offer the real-time, secure trading systems that newer financial markets provide.
These older systems also struggle to use modern solutions like cloud computing, which could help companies scale operations and cut costs.
By not using the cloud, companies can end up spending more money and becoming less flexible.
Outdated systems also slow down the launch of new products and services. In fast-paced industries, this delay can leave companies behind their competitors.
Additionally:
Legacy systems limit the ability to use big data, which is key for making smart business decisions. Without integrating new data tools, companies miss out on valuable insights.
Finally, outdated technology can hurt customer satisfaction. People today expect smooth, personalized experiences, and old systems make it hard to deliver that. For instance, if a retailer’s e-commerce platform isn’t connected to its inventory system, customers might get incorrect stock info or face delays, leading to frustration and lost sales.
Why Companies May Be Hesitant Towards a Transformation
Ever heard the saying "if it’s not broken, don’t fix it?" Companies often think that because their old systems have worked for so long, they’ll keep working just fine. This mindset leads to hesitation when it comes to making changes:
Cost of Transition: Switching to new systems is expensive. It requires buying new technology, training staff, and may cause downtime. Big IT projects can cost millions, and many companies find that too overwhelming
Business Risks: Old systems are critical to daily operations. The fear of business disruptions during the switch can hold companies back. For example, airlines like Delta have faced major system outages because of outdated technology, leading to canceled flights and big losses
Complexity: Large companies have complicated IT systems. Figuring out how to replace them can be overwhelming. For example, banks like JPMorgan Chase process huge numbers of transactions every day, making the switch risky and difficult
Resistance to Change: Employees and management may resist new systems because they’re used to the old ones. Companies need to manage this resistance carefully to succeed in modernizing
Security Neglect: Many companies don’t think they’ll be hit by cyberattacks, which leads to not upgrading their security. This can be risky, as older systems are more vulnerable to attacks
