Examples of work

Offshore and Nearshore Outsourcing

Advised on some of the first offshore outsourcing projects into India, and has since been engaged around the world in offshore and nearshore outsourcing projects for customers and providers.


IT and Outsourcing Providers

Represents global technology and IT and business process (BPO) outsourcing providers like Tata Consultancy Services and Dell as well as more niche IT, business process outsource and specialist business process/service providers, many NASDAQ and NYSE listed. Most representation is in transactions that are important enough to providers in terms of business and risk for them to instruct external counsel.


Banking and Financial Services

Customer-side clients include UK and international banks (including Barclays and Royal Bank of Scotland) and insurers, utilities and infrastructure companies. Almost all of the transactions are business critical and/or within regulated sectors, so IT and outsourcing transactions are material both to clients and often to their regulators.


IT and Outsourcing as Economic Development

Advised the Commonwealth Secretariat, the African Development Bank, the Islamic Development Bank and various African, Asian and CARICOM governments on the use of offshore and nearshore IT and outsourcing as accelerators of economic development.


Areas in which I advise clients

  • IT Outsourcing

    Much of IT infrastructure outsourcing and applications development and maintenance (ADM) is becoming commoditised, standardised and, in the case of infrastructure operations, automated. I advise customers and providers on both IT infrastructure and ADM outsourcing in their newest forms, allowing for the flexibility, change and innovation that are now expected of providers in contractual relationships.
  • Cloud Computing

    Public cloud computing has become more acceptable to customers, and is set to become even more popular with them, increasingly with regulated institutions like banks and insurance companies. There remain several legal, regulatory and operational challenges for customers adopting public cloud computing. With the experience my team and I have had working with both customers and providers in cloud computing, I advise customers at the start of such projects of the likely pressure and sticking points in utility cloud projects. The sooner these are addressed and resolved, the better, otherwise organisations can spend months on the technical, operational, integration, financial and commercial aspects of cloud computing without addressing the operational and regulatory risks.
  • IT Remediation in Financial Services

    The story of IT in the UK financial services sector is in two parts, remediating legacy IT estates and applications, and digitisation. It is well-known that the established banks and other financial institutions rely on aged IT infrastructure, some of which periodically falls over. The PRA and FCA are clearly concerned about increased operational risk and are intervening more frequently. Reported IT system failures and regulatory intervention are now the norm. This situation continues to drive substantial and complex infrastructure outsourcing to remediate IT risks. My team and I have extensive experience of representing financial institutions in IT remediation projects.
  • Digitisation

    The other part of the story for the UK financial services sector, driven by the need to reduce the cost of interacting with customers through large branch networks, greater efficiency in customer transactions, reaching and transacting with younger customers and potential customers through digital channels of their choice, customer analytics and increasing the range of services that can be offered to older and younger customers. FinTech and the rise of challenger banks in the UK are also part of the story. But digitisation adds legal and regulatory risk to financial services operations. The FCA monitors closely how financial institutions are using social media and other digital services. I help banks and insurers in leading-edge digitisation projects and we are beginning to engage with some of the challenger banks starting up in the UK, for whom technology is the game changer.
  • Business Process Outsourcing and the Rise of Software Robotics

    “Generic” BPO, typically finance and accounting (F&A) outsourcing, but also CRM is, like IT infrastructure outsourcing, being challenged by automation, artificial intelligence (AI) and software robotics processes. Other forms of specialist BPO, like policy and claims administration in the insurance markets, are also becoming more commoditised and automated. We have seen the development of several specialist platforms in these markets. I represent both customers and providers in these markets, and we are beginning to work with some of the leading automation and robotics providers, along with integrators, to keep track of and learn from developments in the software robotics market.
  • Offshore, Nearshore and “No Shore” Outsourcing

    While there are political, economic, social, technological, social and even legal pressures against offshoring and the need to “re-shore”, outsourcing from lower cost countries, whether half way round the world or closer to home, is still important for customers and providers. Lower cost processing remains the main driver for outsourcing. But as the global delivery model has been extended from a handful of global providers to a wider range of providers, including those based in India, the choice of which shore, and multi-shore delivery centres has grown. And cloud computing and automation have seemed to create the “no shore” option. This is now illusory, however, as data residency, and therefore which “shore” houses a customer or provider’s servers is a big point since the Snowden disclosures.
