College of Economic & Management Sciences

Dr Thobeka Ngcamphalala, a lecturer in the Department of Applied Management at Unisa’s College of Economic and Management Sciences, has earned a Doctor of Philosophy in Management Sciences degree, specialising in Transport Economics. Supervised by Prof Marcus Ambe, her research presents a transformative procurement framework for South Africa’s commuter bus industry.

Her doctoral study, titled "A Procurement Framework for the Commuter Bus Industry in South Africa", employed a qualitative, multi-case exploratory approach. Drawing insights from government officials, bus operators and industry experts, the research uncovered critical misalignments between procurement processes, legislative mandates and national socioeconomic goals.

Ngcamphalala’s framework offers a structured, practical tool to boost regulatory compliance, operational efficiency and transparency – filling a longstanding gap in the sector. "This research contributes significantly to public procurement literature and can aid policymakers and stakeholders in promoting inclusive economic participation," she explains.

A journey rooted in experience and passion

Before joining academia full time, Ngcamphalala worked as a transport consultant, helping in managing the Mpumalanga scholar transport programme. "That experience sparked my interest in commuter bus operations – especially systems like PUTCO and North West Star," she notes. Her logistics and aviation procurement background enriched her understanding of supply chains and fuelled her curiosity.

Since joining Unisa in 2014, her passion for the sector has only grown. Her master’s research, focused on commuter bus contracting in Gauteng, laid the groundwork for this national study. "My goal was to create a procurement framework that is efficient, transparent and aligned with South Africa’s development goals," she says.

Navigating personal and academic hurdles

Completing a PhD during the Covid-19 pandemic was no small feat. Study leave began in 2021, a time marked by emotional strain, remote supervision and delays. "I struggled with perfectionism, anxiety and the pressure to complete within the study leave period," she shares. Family responsibilities and personal challenges added to the emotional weight.

What kept her going? "The unwavering support from my family, friends and fellow PhD candidates. Their encouragement during moments of doubt reminded me that even imperfect progress is still progress."

Guided by mentorship and collaboration

Central to her success was the mentorship of Prof Marcus Ambe, a long-time collaborator with whom she co-authored her first journal article in 2016. "His guidance shaped my academic journey profoundly," she says. Their partnership also saw the birth of the African Institute for Supply Chain Research and the 2024 Pan African Conference on Supply Chain Management, held in Kenya.

Beyond academia, Ngcamphalala stays connected to public transport industry advisors and academic peers, contributing to sector-relevant research and literature. She is a co-author of Logistics Management: An African Perspective, currently prescribed at several universities.

What’s next for Dr Ngcamphalala?

With her doctorate now complete, Ngcamphalala is eyeing promotion to senior lecturer and, ultimately, a professorship. She is also pursuing collaborations with industry partners to translate her research into practical change.

"I want to bridge the gap between academic theory and industry practice – especially in public transport and procurement," she says. Her focus is firmly on impact: policy, implementation and transformation.

Advice to future PhD students

"Pursuing a PhD is deeply rewarding – but it demands resilience, discipline and self-belief," she advises. "There will be tough days, but don’t give up. A solid support system can make all the difference. And yes, that red gown is as warm in winter as it looks!"
