The Importance of Investing in an IT Department: Why Legacy Systems and Technical Debt Are Holding Your Business Back

Published: 03.10.2025Updated: 03.10.2025

In today’s business world, technology is an undeniable core component of virtually every organization. Whether it involves customer interactions, payment processing, or product logistics, companies simply cannot afford to fall behind in the field of Information and Communication Technology (ICT). However, outdated systems and an increase in what is called “technical debt” are still common — terms that indicate a company is not maintaining its ICT infrastructure optimally. This outdated technology has a significant impact on an organization’s efficiency and increases security risks.

In this article, we will explore why it is important to continue investing in a modern ICT department, the effects of outdated systems, and the consequences of technical debt for both the operations and the security of your company.

What is ICT and why is it so important?

ICT, or Information and Communication Technology, is an umbrella term for all technologies companies use to collect, store, process, and communicate information. This includes both hardware and software, such as computers, servers, networks, and applications. In an era where digitalization has become the norm, ICT plays a crucial role in the business operations of organizations in virtually every sector.

From cloud solutions to internal communication tools and from data management systems to cybersecurity measures — ICT makes it possible to perform tasks faster, more efficiently, and more securely. In many cases, the dependence on technology has become so great that companies simply cannot function without a well-maintained and well-structured ICT department.

What is “technical debt”?

A term that often comes up when we talk about ICT departments and outdated systems is “technical debt.” This refers to the cumulative costs of technological decisions that were made quickly or temporarily in the past, but that have long-term consequences for the efficiency and stability of systems.

Imagine a company carries out a software update but instead of the full upgrade needed for the long term, decides to implement a temporary solution. For example, by installing a quick fix that later causes problems. While this may save money and time initially, significant costs arise later if the technology is not properly maintained and updated. The software will eventually become outdated, harder to integrate with other systems, and may develop bugs and security vulnerabilities that need to be resolved.

Just like financial debt can accumulate interest, “technical debt” can pile up over time. As outdated technologies build up, it becomes increasingly difficult to catch up, resulting in higher costs for maintenance, improvements, and in the worst case, migration to new systems.

The impact of outdated ICT systems on efficiency

Outdated systems can significantly hinder efficiency within an organization. They can cause delays, reduced productivity, and a poor customer experience. These are some of the main consequences of using old technology:

1. Slower processing times

Older systems are often slower than modern systems, meaning data is processed more slowly. This slows down business processes and can result in longer wait times for customers and employees. If your company relies on real-time data, such as with online orders or logistics tracking, an outdated system can cause delays that leave customers dissatisfied.

2. Limited scalability

Outdated systems are often not designed to scale with the growth of a company. As a company expands, it can become more difficult to extend older infrastructures to meet new demands. This can make businesses less flexible in responding to changing market conditions, weakening their competitive position.

3. Less innovation

Organizations that fail to invest in modern technologies risk falling behind their competition. Outdated systems limit opportunities for new innovations and the implementation of new features that could improve customer satisfaction. Companies that do not keep up with technological progress can eventually fall behind, while competitors optimize their processes and respond more quickly to customer needs.

4. Integration issues

Modern technologies are often designed with integration in mind. They can easily communicate with other systems and new technologies, ensuring seamless data exchange and streamlined business operations. Outdated systems, however, are often difficult to integrate with new technologies, leading to inefficiencies and possible duplication of work.

Outdated systems and their impact on security

One of the biggest risks of outdated ICT systems is their effect on security. Older software and hardware often contain vulnerabilities that are not fixed because they are no longer supported by the vendor. This increases the likelihood of cyberattacks, data breaches, and other security incidents. The main risks outdated systems pose in terms of security include:

1. Loss of software support

When a system becomes outdated, the vendor often stops providing security updates. This means known vulnerabilities are not patched, making the system an attractive target for hackers. Using outdated software can therefore have serious consequences for an organization’s overall security.

2. Increased risk of data breaches

Data breaches are one of the biggest security threats today. Organizations using outdated systems face a higher risk of breaches because their systems may not be adequately protected against external attacks. Sensitive information, such as customer or financial data, could fall into the wrong hands.

3. No protection against new attacks

Cybercriminals continuously develop new methods and techniques to attack businesses. Outdated systems are often unequipped to defend against the latest forms of cyberattacks, such as ransomware, phishing attacks, or advanced persistent threats (APTs). This makes companies using outdated systems particularly vulnerable.

4. Compliance risks

Many industries, such as healthcare and financial services, have strict regulations regarding data security and privacy. Using outdated systems can expose a company to compliance risks, as older systems often fail to meet the requirements of legislation such as the General Data Protection Regulation (GDPR) in Europe.

Why investing in an ICT department is essential

Investing in a strong ICT department is not only necessary to prevent outdated systems and technical debt from piling up, but also essential for a company’s long-term strategy. A well-managed ICT department not only provides technical support, but also plays a strategic role in achieving business objectives. Here are some reasons why continuous investment in ICT is crucial:

1. Innovation and competitive advantage

Companies that continue to invest in their ICT departments can innovate faster and implement new technologies more easily. This enables them to stay ahead in their industry, improve customer satisfaction, and take advantage of new market opportunities.

2. Long-term cost savings

Maintaining a modern IT ecosystem means lower costs for maintenance and troubleshooting. The costs of maintaining outdated systems can skyrocket, especially as more technical debt builds up that must eventually be repaid. By investing in new technologies, businesses can increase efficiency and save money in the long run.

3. Better security

By investing in modern ICT solutions, companies can benefit from the latest security measures. This not only helps protect customer and employee data, but also ensures compliance with necessary laws and regulations.

4. Flexibility and scalability

Modern technologies provide businesses with the flexibility and scalability needed to adapt to changes in the market. This makes it easier to quickly respond to new opportunities and threats.

Conclusion

Investing in a well-managed and up-to-date ICT department is essential for business success in the digital age. Outdated systems and the accumulation of technical debt can seriously jeopardize the efficiency and security of your organization. By investing in modern technologies and systems, you can not only improve performance but also ensure security and comply with necessary regulations.

If companies fail to maintain their ICT departments, they risk not only losing their competitive position but also facing high costs to resolve technical debt and security issues. By proactively investing in technology and continuously keeping systems up to date, businesses can reap the benefits of increased efficiency, security, and innovation.
