What is industrial and systems engineering?

Industrial and systems engineering is a branch of engineering that deals with the design, analysis, improvement and management of systems comprising people, machines, information and resources. What defines it is not working with a specific component but with the entire system: how all the parts interact and how to ensure that the whole system functions as efficiently as possible.

The term ‘and systems’ has a precise technical meaning. It refers to the incorporation of systems theory, computational simulation and quantitative analysis into the traditional approach to industrial engineering. Today, the classic tools of process improvement are complemented by the ability to digitally model a process, simulate scenarios and make data-driven decisions.

The result is a form of engineering that is particularly useful in highly complex environments: global logistics systems, hospital networks, automated production plants or supply chains with multiple variables.

How does it differ from traditional industrial engineering?

Although they share a common foundation, the difference between the two degree programmes is real and has practical implications for the professional profile:

Industrial engineering prepares you to optimise how things are done. Industrial engineering and systems engineering equips you to redesign the entire system that makes something work.

What does an industrial and systems engineer do?

An industrial and systems engineer acts as the link between day-to-day operations and the organisation’s strategy. Their most common duties include:

• Analysing and mapping processes: identifying bottlenecks, inefficiencies and opportunities for improvement in a company’s workflows.
• Designing and optimising systems: proposing improvements to a plant’s layout, information flows or the architecture of a management system.
• Modelling and simulating: creating digital models of processes to predict how they will react to changes before implementing them, thereby reducing risks and costs.
• Quality control: implementing statistical control systems to ensure that products or services meet the required standards.
• Manage the supply chain: reduce lead times, minimise stock levels and coordinate suppliers and customers to ensure an efficient flow of materials.
• Leading continuous improvement projects: driving Lean or Six Sigma initiatives with multidisciplinary teams to sustainably increase productivity.
• Analysing data to inform decision-making: drawing conclusions from production, logistics or sales data to guide operational strategy.

In short, this is the professional who helps organisations run more effectively through a combination of analytical thinking, a systems-based approach and mastery of optimisation tools.
