Dr. Ratha Letchimanan -Most Impactful Global Business Leaders 2026

Global supply chains are undergoing a profound shift as logistics leaders balance speed, resilience, and digital transformation in an increasingly complex world. In this evolving landscape, demand leaders who can balance operational discipline with constant transformation. Dr. Ratha Letchimanan, Chief Operating Officer of GIGA Maritime Group (GMG) of Companies, has spent more than two decades navigating that intersection.

Her journey spans roles that required leading complex transport networks, managing large operational portfolios, and driving continuous improvement across multi-site logistics environments. Alongside her operational leadership, she has continuously invested in academic growth, progressing from a Computer Science degree to an MBA and ultimately earning a PhD. Before stepping into her current leadership role, she spent over a decade at DHL Supply Chain, where she advanced through several strategic positions while strengthening operational performance, digitalisation, and cross-functional execution. During an exclusive conversation with The Portfolio Magazine, she discussed her journey, challenges, and lessons.

What are the biggest challenges you face in your current leadership role, and how have your earlier experiences helped you navigate them?

Leading multiple divisions means operating in an environment where priorities constantly compete for attention. Technical operations, fleet governance, and fleet planning and execution all move at different speeds, yet they must remain aligned to deliver on commitments, maintain driver compliance, and ensure fleet readiness.

Such complexity cannot be managed through isolated decisions. A systems perspective becomes essential. Experience across IT, transportation, project management, and operations helped me understand how different functions influence one another. Academic training in Computer Science first shaped the way I approach structured problem solving, while later studies in management strengthened my ability to connect operational realities with strategic thinking. Operational clarity begins with visibility. Structured KPIs and corrective action frameworks help teams understand where performance stands and where improvement is needed. However, long-term consistency comes from something deeper than systems alone.

Teams must understand how their individual responsibilities contribute to the larger operational picture. When people see the connection between their decisions and overall performance, accountability becomes natural, and improvement becomes continuous rather than forced.

When scaling operations, how do you decide which legacy processes should remain and which should evolve?

Growth often creates pressure to modernize processes quickly. Experience has shown that transformation rarely succeeds when organizations rush to replace existing systems without understanding why they were created in the first place. Many legacy processes carry operational wisdom built over years of experience. Functions such as fleet readiness, driver compliance, and delivery commitments provide the stability that keeps operations reliable. Removing those foundations would introduce unnecessary risk.

At the same time, scaling operations inevitably reveals inefficiencies. Limited visibility into fleet availability, repair patterns, or driver commitments can slow decision-making and reduce flexibility. These areas present opportunities for thoughtful innovation. Encouraging teams to question processes plays a crucial role in identifying those opportunities. Instead of executing routines automatically, teams are encouraged to ask what value each process delivers. Pilot initiatives supported by data-driven KPIs and digital dashboards help test improvements carefully. Gradual implementation ensures that innovation strengthens operational performance while the stability of essential processes remains intact.

Was there a defining career decision that changed how you approach leadership?

One of the most significant decisions in my career was leaving DHL after thirteen years. The organization had become a familiar environment in which I had managed roles spanning operations, project initiatives, transportation, and improvement programs.

Leaving that stability meant stepping into a niche industry where many systems and operational dynamics were new. The decision involved uncertainty, yet it also created an opportunity to view operational challenges through a completely different lens.

A new environment encouraged a more objective evaluation of processes. Instead of continuing established routines, teams were encouraged to understand why those processes existed and whether they still served the business effectively.

Structured performance dashboards, operational metrics, and corrective frameworks helped strengthen fleet visibility and driver compliance. More importantly, the experience reinforced an important lesson about leadership. Professional growth often begins when leaders are willing to leave familiar environments and approach challenges with curiosity rather than certainty.

“Operational excellence does not come from following routines. It begins when leaders encourage teams to question systems, understand their purpose, and continuously improve how work gets done.”

As digital transformation accelerates, what capabilities will define the next generation of engineering and operations professionals?

Digital transformation has fundamentally changed how operational decisions are made. Data literacy has therefore become a core capability for professionals working in engineering and operations.

Access to data alone does not guarantee better outcomes. Professionals must be able to interpret insights, question assumptions, and translate analysis into operational improvements. Critical thinking remains essential in an environment where information is abundant, but judgment determines impact. Modern operations also require collaboration across departments. Technical teams, safety departments, HR functions, and operational leaders must coordinate closely to ensure improvements translate into measurable results.

Continuous learning ultimately defines long-term relevance. Technology and operational models continue to evolve rapidly. Professionals who remain curious and adaptable will always be better positioned to guide organizations through change.

Which technological developments will shape operational excellence in the coming decade?

Operational management is gradually moving from reactive problem-solving toward predictive decision-making. Technologies such as advanced analytics, AI-driven platforms, predictive maintenance systems, and real-time fleet monitoring will play a defining role in that transition.

Many of these capabilities are already shaping everyday operations. Digital dashboards, predictive analytics tools, IoT sensors, and GPS-enabled route planning systems provide real-time visibility into fleet availability, driver compliance, and operational performance indicators. Power BI dashboards and structured reporting frameworks help transform raw operational data into insights that leadership teams can act upon quickly.

Technology alone does not create operational excellence. Sustainable improvement emerges when leaders and teams combine technological capabilities with thoughtful interpretation and disciplined execution.
