Derek Wilcocks on how AI finally Vitality

Discovery group CIO Derek Wilcocks on personalised Vitality, the limits of AI coding and why growth beats cost-cutting.
Derek Wilcocks, group CIO at Discovery, says AI has finally given the group the ability to do something it has wanted to do since Vitality launched more than 25 years ago: personalise it.
Speaking on TechCentral’s Meet the CIO podcast series, brought to you by NTT DATA, Wilcocks said Personal Health Pathways is built on AI models trained on member data collected since 2000, and used only with a member’s consent. For most of Vitality’s history, the targets were identical for everyone. The programme can now suggest a walk, a glucose test or a cancer screening rather than a run.
Wilcocks spent 23 years at Dimension Data, now NTT Data, where he ran Internet Solutions, served as group CIO and led the Middle East and Africa business as CEO. He was the 12th person to join Internet Solutions and founded a subsidiary that sold the first firewalls into South Africa’s banks. He joined Discovery in 2018.
In the discussion, he is candid about the limits of AI in software development. Discovery is measuring efficiency gains of roughly 20-25% in some areas from AI coding tools, but developers in large corporates were spending only a quarter to a third of their time writing code to begin with. Senior developers use all the major agentic coding frameworks, though the group has spent heavily on guardrails constraining what those tools are allowed to do.
Wilcocks also discusses:
• Why Discovery’s health and life businesses buy no traditional enterprise software, developing everything from scratch;
• Why he thinks Elon Musk is right about the direction but wrong about the timing on the end of source code, and the three problems standing in the way – explainability, efficiency and maintainability;
• Why the decade in which knowing how to code was enough to walk into a job has come to an end;
• How a federated model with around 14 CIOs across the group is held together by mandatory central security, privacy and ethics functions – and what happened when Discovery’s data scientists were asked to simplify the AI rules written for them;
• Why he sees AI at Discovery as primarily a growth story rather than a cost-cutting one, with staff retrained and redeployed rather than cut; and
• His route into computers, from a Commodore Vic-20 with 4KB of memory to the father who cured him of wanting to be an electrical engineer.
