Why are legacy systems still used

Apart from those you see in the image above, there are three other reasons that we can think of:

  1. Emotional connect
  2. Return on initial investment
  3. Confusion about where to start with modernization

While many might jump the gun and say, hey, the second point doesn’t make sense, if we are here, we have made great early profits with immaculate turnovers.

Don’t worry. We will clarify our stand while covering everything related to the existence of legacy systems in this section.

So, why do legacy systems persist?

Businesses often hold onto their legacy systems due to a mix of practical and, at times, sentimental reasons. Understanding these factors is crucial for any leader contemplating the leap toward system modernization.

1. The comfort trap

  • Proven stability: Legacy systems have stood the test of time, consistently running without major failures. This reliability makes businesses cautious about undertaking changes that could jeopardize established operations. 
  • Fear of disruption: Upgrading critical systems can lead to unforeseen complications. The potential for operational downtime during a transition is a significant deterrent, as any interruption could impact daily business functions and customer service.

2. The high cost of holding on

  • Sunk costs: Significant investments have been made in current systems through acquisition, customization, and maintenance. The immediate financial outlay and resource allocation required for a complete overhaul can be daunting.
  • Unexpected expenses: Beyond the visible costs, modernization includes indirect expenses such as training employees on new systems, transferring existing data, and resolving compatibility issues with current processes. 

3. Tech debt and integration headaches

  • Technical debt: Many legacy systems use outdated technology that may no longer be supported, making maintenance challenging and costly. Finding IT professionals skilled in older technologies is becoming increasingly difficult.
  • Customized solutions: Some systems are tailor-made to handle unique business operations. Replacing these can disrupt specific functions central to a company’s operations.
  • Integration hurdles: Legacy systems often lack the flexibility to integrate smoothly with newer technologies, leading to additional complexities and costs in ensuring systems communicate effectively.

4. Change fatigue

  • Comfort with familiarity: Employees accustomed to a particular system may resist switching to newer technologies. The transition requires training and support to adapt to new workflows. 
  • Organizational inertia: Legacy systems are deeply integrated into the workflows of many organizations. Changing these systems requires altering established processes, which can be a significant barrier to modernization. 

While the hesitation to move away from legacy systems is understandable, business leaders must weigh in the potential drawbacks of working with outdated technology.

Examples of legacy systems in different industries

Here are detailed examples from the retail, manufacturing, and supply chain and logistics industries, where the impact of outdated systems is particularly acute: 

1. Retail Industry: Point-of-sale (POS) systems

An example of a legacy system in the retail sector is an older Point-of-Sale (POS) system.  

These systems are critical for daily operations, sales transactions, inventory management, and customer data. 

However, many older POS systems are based on outdated software that does not support integration with newer e-commerce platforms or mobile payment technologies. 

This limitation becomes evident during peak shopping seasons when customer demand for quick and diverse payment options increases. 

For instance, a retail chain using a legacy POS system might find it challenging to implement omnichannel strategies effectively, such as synchronizing online and in-store inventory or offering seamless customer experiences across different sales channels. 

This can lead to missed sales opportunities, discrepancies in inventory data, and a failure to capture valuable consumer behavior insights. 

2. Manufacturing industry: ERP systems

In manufacturing, legacy Enterprise Resource Planning (ERP) systems are common. 

These systems integrate various business processes, from production scheduling to procurement and inventory management. 

However, many of these systems, designed decades ago, are incompatible with new manufacturing technologies like IoT (Internet of Things) devices or real-time data analytics tools. 

For example, a manufacturer might use a state-of-the-art ERP system in the early 2000s. 

While it handles basic functions well, it cannot easily connect with modern sensor-based equipment or provide real-time analytics, which is crucial for predictive maintenance and optimizing production lines. 

Due to reactive maintenance strategies, this results in inefficiencies, increased downtime, and higher costs. 

3. Supply chain and logistics industry: Warehouse Management Systems (WMS)

Legacy Warehouse Management Systems (WMS) are widespread in supply chain and logistics. These systems are vital for tracking inventory levels, managing warehouse operations, and coordinating logistics. 

However, older WMS platforms often lack the ability to integrate with advanced tracking technologies, such as RFID (Radio Frequency Identification) or GPS tracking, which limits their effectiveness in today's fast-paced logistics environments. 

Consider a logistics company that relies on a legacy WMS. This system may not support real-time tracking of goods, leading to inefficiencies in warehouse operations and difficulties in providing accurate delivery estimates to customers. 

Such limitations hinder the company’s ability to compete with others that offer faster, more reliable, and transparent shipping services.

The next section will explore different legacy system modernization approaches and how to develop a winning modernization strategy. 

But for now, remember: modernizing your legacy system isn't a cost; it's an investment in growth.

Strategic modernization approaches of your legacy system

Now that you have understood the issue and want to use modernization as your pickaxe, you might feel confused where do you start?

This section will equip you with the knowledge to chart your path to a future-proof system. 

1. Digging deep to define your goals

Modernization is a journey, not a destination. 

The first step is a thorough assessment of your existing systems. Here's what you need to uncover: 

  • System functionality: What core functionalities are business-critical? 
  • Technical debt: How much-outdated code and infrastructure are dragging you down?
  • Integration needs: How well does your legacy system interact with other applications? 
  • Security status: Are your systems vulnerable to cyber threats?

Prioritization is key.

Based on your assessment, identify the areas that will yield the most significant improvements (business value). This will guide your choice of modernization strategy.

2. The 7 R's of Modernization

Legacy system modernization approaches

Modernization isn't a one-size-fits-all solution. Here's a toolbox with various approaches, each with its strengths: 

  • Rehost: Move your existing application "as-is" to a new cloud environment. Ideal for low-touch, cost-effective updates. 
  • Replatform: Migrate your application to a new platform but keep the core functionality. Offers a balance between cost and modernization benefits. 
  • Refactor: Revamp the internal code of your application without changing its core functionality. Good for improving efficiency and maintainability. 
  • Rearchitect: Completely overhaul your system's architecture for modern scalability and flexibility. Recommended for complex systems requiring significant transformation. 
  • Rebuild: Develop a new system from scratch, leveraging modern technologies. This option is suitable for outdated systems with limited future potential. 
  • Replace: Adopt a commercially available software solution that meets your needs. Consider this for readily available, well-supported solutions. 
  • Retire: If a system is no longer crucial, decommission it responsibly. This will streamline your IT landscape and free up resources. 

Choosing the right "R" depends on your assessment findings and business goals. 

Encapsulate:

Encapsulate is an option for revitalizing your existing applications. It's a cost-effective way to leverage the valuable core functionalities of your legacy system.

Here's how it works: 

Think of it as wrapping a gift. Encapsulation creates a new layer around your old system, hiding the internal workings but giving you easy access to its core features through a modern API (think of the API as the fancy ribbon). 

Focus on what matters most. This approach keeps the existing system intact, so you don't have to worry about a complete overhaul. It's ideal if your legacy code is solid, the application is critical to your business, and it still functions well. 

However, it's important to remember that encapsulation primarily addresses the accessibility of your legacy system, not its underlying maintenance issues. So, if your old system is a constant headache to maintain, encapsulation might not be the long-term solution. 

Here's when Encapsulation makes sense:  

  1. You want to integrate your legacy system with newer applications. 
  2. You need to expose specific functionalities of the old system to external partners or mobile apps. 
  3. You want to improve the user experience by providing a modern interface to access legacy data and functions. 

3. Choosing the right modernization path 

With your assessment complete and the "7 R's" in mind, it's time to choose your path. Here are some key considerations: 

  • The complexity of your legacy system: Simpler systems might benefit from Rehosting or Replatforming, while complex ones might require Rearchitecting or Rebuilding. 
  • Budget: Refactor and Rehost are generally less expensive than Rearchitect or Rebuild. 
  • Desired level of change: Refactor offers incremental improvements, while Rearchitect or Rebuild delivers a more comprehensive transformation. 
  • Future scalability needs: Replatform or Rearchitect provides a more scalable foundation for future growth. 

NOTE: There's no single 'best' approach. The key is to align your strategy with your business objectives.
