Complexity is making a comeback

Most organisations would agree that their technology environment is significantly better than it was ten years ago. Infrastructure has moved to the cloud, applications have become easier to deploy and technology teams spend far less time managing the foundations than they once did. New capabilities can be introduced in weeks rather than months and many of the challenges that once dominated IT departments have either disappeared or become someone else’s responsibility.

Despite these improvements, many leaders are left with a different feeling. Projects often take longer than expected, changes require coordination across multiple teams and suppliers, and incidents can reveal dependencies that few people fully understood. Questions such as “Why is this process so complicated?” or “Who actually understands how this service works from end to end?” have become increasingly common. This does not mean modernisation has failed. In many respects it has been highly successful. What it does suggest is that the complexity organisations face today, looks very different from the complexity they were trying to solve a decade ago.

The old complexity problem has changed shape

A decade ago, complexity was relatively easy to identify. It lived inside infrastructure, applications and technology platforms. Technology teams could point to it, document it and invest in reducing it. Standardisation, consolidation and cloud adoption all helped simplify environments that had often grown organically over many years. Those investments delivered real benefits. Technology became easier to access, easier to deploy and easier to scale. Most organisations are operating on stronger foundations today than they were ten years ago, which is why very few would choose to return to the environments they left behind.

While organisations were simplifying technology, they were also becoming more connected. New SaaS platforms were introduced, integrations multiplied, suppliers became embedded within critical services and automation linked processes that were once performed manually. More recently, AI has started interacting with information, workflows and decisions across the organisation.

Each of these decisions often made perfect sense at the time. They improved efficiency, reduced effort or solved a specific problem. Over time, however, they also created an environment where understanding how everything works together became more difficult than understanding the individual technologies themselves.

The complexity did not disappear. It simply changed shape.

The challenge with hidden complexity

One of the reasons this newer form of complexity often goes unnoticed is that it remains largely invisible during normal operations. Customers continue to receive services, staff continue to perform their work and business processes appear to function as expected. The technologies, suppliers and workflows supporting those activities fade into the background because there is little reason to think about them.

A supplier outage, cyber incident, software defect or major change initiative can quickly change that picture. What appears to be a straightforward service may suddenly reveal dependencies on multiple systems, teams, suppliers and processes. The challenge is rarely the failure itself. More often, it is understanding the impact of that failure across the broader environment and determining what else might be affected.

These moments often reveal how well an organisation understands its environment. Technology excellence is not only demonstrated when everything is working as expected. It is equally demonstrated through an organisation’s ability to respond, adapt and continue delivering critical services when things do not go according to plan.

Making complexity visible

The organisations that manage complexity most effectively are rarely those with the fewest systems or the simplest technology environments. They are usually the organisations with the clearest understanding of how they create value.

They understand the services they provide, the capabilities required to deliver those services and the technologies that support them. They understand which suppliers are critical, where important dependencies exist and how a change in one area may affect another. This visibility helps them make better decisions, manage change more effectively and reduce the likelihood of being surprised by their own environment.

Complexity rarely sits within a single technology. It often emerges across the relationships between services, capabilities, suppliers and technology. When organisations can visualise those relationships, hidden dependencies become easier to identify and the impact of change becomes easier to understand. Complexity becomes far more manageable when it is visible.

Complexity is making a comeback

Technology continues to become more capable, more accessible and easier to deploy. Few organisations would choose to return to the technology environments of a decade ago. The challenge today is different.

Complexity has shifted from individual technologies to the relationships between technologies, services, suppliers, capabilities and people. These relationships create value every day, but they can also become a source of risk, inefficiency and operational debt when they are poorly understood.

Technology excellence is not measured by how modern an organisation’s technology appears. It is measured by how well the organisation understands its environment, manages change and responds when things do not go according to plan. Complexity has not disappeared. It has simply moved to places that are harder to see.
