The Operations & Technology Management subject group

Back to Subject groups

About the subject group

Organisations achieve reliable performance and competitive advantage through the design and management of intra- and inter-organisational projects, processes and routines. The Operations & Technology Management group studies the determinants of superior performance from the perspective of these activities. Focused on practice-based research through deep engagement with partner organisations, group members address a wide spectrum of management challenges and employ a diverse set of research methods, including theoretical, analytical, empirical, and behavioural models that draw from operations research, economics, psychology and sociology, as well as state-of-the-art data analytics techniques applied to large datasets.

The research of the group falls broadly into the following categories:

  • Innovation and new product development (Stelios Kavadias, Christoph Loch, Nektarios Oraiopoulos)
  • Healthcare operations (Feryal Erhun, Houyuan Jiang, Stefan Scholtes)
  • Operations strategy (Jane Davies, Stelios Kavadias, Christoph Loch, Nektarios Oraiopoulos)
  • Supply chain management and risk (Feryal Erhun, Benn Lawson, Daniel Ralph)
  • Behavioural decision-making and behaviour analytics (Christoph Loch, Kishore Sengupta, David Stillwell)

Industry engagement

Members of the Operations and Technology Management Group engage frequently with organisations in the business and public sectors and their research agenda is stimulated by regular contacts with senior personnel of regional, national and international organisations such as Bank of China, British Airways, BP, Ernst & Young, Ofgem, Defra, Shell, UK Department for Transport, NICE and Cambridge University Hospitals.

Recent and current engagement projects undertaken by members of the group include:

  • Professor Stefan Scholtes, Professor Feryal Erhun, Dr Houyuan Jiang, together with colleague Dr Paul Kattuman and PhD students Lidia Betcheva, Tom Pape and Antoine Feylesouffi, started a research collaboration with Addenbrookes Hospital and the East of England Region to support the local NHS response to the COVID-19 emergency. Their work has served a population of seven million people in the East of England, supporting key timely decisions in terms of hospital and ICU beds, lockdown easing measures and hospital activities.
  • Professor Stelios Kavadias completed his sabbatical at AstraZeneca in 2019, where he helped the R&D portfolio & project management executives in exploring ways by which AstraZeneca could increase their R&D productivity. His effort led to the creation of a standardised template with sets of questions that help project teams to check that they are not being overly risk adverse and that they are considering the implications of their decisions and phase plans on drugs’ approval time.
  • Professor Danny Ralph has been supporting several businesses through the Cambridge Centre for Risk Studies (CCRS) that he directs. The Centre has established itself at the forefront of research into cyber risk insurance products and cyber risk management internationally. Their work has been used widely by a number of organisations including Risk Management Solutions (RMS), Pool Re, and Lloyd’s of London.
  • Dr Benn Lawson worked with a global automotive producer to understand the profitability implications of building vehicles to customer order versus building to stock. He is also working with a sustainability-focused NGO to assess the effects of worker empowerment interventions in supplier factories.
  • Dr Aris Oraiopoulos has consulted with companies in the pharmaceutical industry on strategies for drug development.
  • Dr Kishore Sengupta has served as advisor on several projects with the US Government Department of Defense and NASA, and has consulted with organisations in Silicon Valley and Hong Kong. He has also worked at the AT&T Network Software Center (now Lucent Technologies) and Ernst & Young.
