The main plenary room at the Meet Health Event's NHS Strategy Summit 2026 in Westminster held the kind of audience that rarely sits still for long. Chief executives, chief operating officers, trust directors from across England, people whose calendars are currency and whose attention is rationed accordingly. Yet when Ming Tang, outgoing Chief Digital and Data Officer of NHS England, took her place on stage for what she had already confirmed was her final appearance in role, the dynamic shifted. This was not a valedictory performance. It was closer to a debrief.
The format was a question-and-answer session, chaired by William Claw, Chief Operating Officer at Central North West London NHS Trust. The conversational structure stripped away the usual padding of keynote theatre. There were no prepared slides to hide behind. What followed was one of the more honest public assessments of where NHS digital transformation actually stands, delivered by someone with sixteen years of institutional memory and, crucially, nothing left to lose politically.
Tang joined the NHS at a time when digital infrastructure was still largely treated as an IT concern rather than a strategic one. Over sixteen years, she moved through the organisation into the most senior digital and data role in the national team, eventually holding the combined brief of Chief Digital and Data Officer. It is a trajectory that reflects both her persistence and the gradual, sometimes reluctant, elevation of digital thinking within NHS leadership. Her focus throughout was consistent: not the technology itself, but the conditions required to make technology work inside a complex public system. That meant grappling with data sharing frameworks, interoperability standards, workforce culture, and the persistent tendency of NHS organisations to build solutions in isolation. These are not glamorous problems. They are, however, the problems that determine whether any of the expensive infrastructure actually delivers.
The substance of her final address was shaped by the questions put to her, but what she chose to emphasise was telling. Two lessons, she said, stood out from her time in the system. The first was structural. Digital and operational delivery cannot run in parallel as separate functions. The failure mode she described is familiar to anyone who has worked in NHS transformation: technology implemented away from clinical and operational process, adoption that never materialises, and a growing accumulation of systems that staff work around rather than with. "You end up with this forest of legacy tech," she said, "that you can't get the job done with." The solution, in her account, is not a technical one. It is about embedding digital capability into the day-to-day work of the organisation, treating it as inseparable from how care is delivered rather than as a project running alongside it. The second lesson was cultural. She described the curiosity of children encountering new technology, the willingness to explore, to break things, to ask what else something can do, and set it against the fear she observes in NHS settings. "How do we create the environment so that people play with the tech?" she asked, and the question was not rhetorical. It carried the weight of someone who has spent years watching well-funded digital programmes fail because the human environment was never prepared.
On data integration, she was precise about where the system falls short. The NHS is capable of point-to-point integration. What it lacks is a consistent, standardised mechanism for doing so at scale. She framed this as primarily a cultural problem rather than a technical one: "The culture of do we really want to operate in a more consistent way" is the real barrier, she argued, not the availability of the technology. Her advice on the federated data platform was similarly direct. Use it. The interconnectivity infrastructure exists. The AI models are already on it. The reasons people give for not adopting it are, in her view, largely political rather than practical. Her one openly regretted failure was the data sharing framework. She wished she had succeeded in getting legislative clarity during the relevant bill. The law does not prohibit the sharing that the NHS needs, she acknowledged, but it does not provide sufficient clarity to overcome institutional risk aversion. Organisations can always find a reason not to share data if the framework allows for ambiguity. That ambiguity has cost the system.
The advice she left for the room was implicitly a critique of how NHS organisations have operated. Stop treating digital as a separate workstream. Stop building point-to-point integrations when platform infrastructure already exists. Stop sending patient-level data across SharePoint in spreadsheets. That last point carried an edge: "There is going to be a cyber issue if we don't actually adopt some of these platforms." It was as close to a warning as the session produced. For the next twelve to eighteen months, she expressed measured optimism. Eight portfolios and business cases are moving through Treasury, which she read as a genuine sign that the system is beginning to take digital investment seriously at a national level. But she was careful to note where that optimism has conditions attached. Local leaders need to be brought into the plan. "We can waste a lot of money really quickly by not having those plans in place," she said. National programmes without local ownership have failed before.
Assessing Tang's tenure requires holding two things simultaneously. There has been real progress. The federated data platform exists. National infrastructure for AI deployment is in place. The business case for digital investment has been made, repeatedly and apparently successfully, at Treasury level. These are not trivial achievements in a system that spent much of the last decade arguing about whether integrated care boards should exist. But the problems she identified on her last day are largely the same ones that have characterised NHS digital transformation for years. Data sharing remains legally murky in practice even if not in theory. Integration defaults to point-to-point. Technology gets implemented without the organisational change required to make it useful. The culture of curiosity she called for has not taken root widely. Progress has been made on infrastructure. Progress on people and culture has been slower, and it is there that the real constraints lie. Those constraints were not primarily of her making. Political cycles truncate legislative ambition. Financial pressure means digital investment is perennially deferred or cut during planning rounds. The NHS is not a single organisation but a system of organisations, each with its own incentives, and alignment is never simply a matter of good arguments.
The institutional knowledge embedded in Ming Tang's sixteen-year tenure is not easily replicated, and the continuity of a long-term digital strategy depends heavily on who succeeds her and whether they are given the same duration and latitude to pursue it. NHS digital transformation has suffered before from leadership churn: strategy resets, programme restarts, and the slow rebuilding of credibility with local systems. What this moment says about the maturity of the NHS's digital ambition is complicated. The infrastructure layer is more developed than it was. The political will, at least at the level of Treasury business cases, appears present. But Tang's own account of the cultural barriers, the fear, the fragmentation, the persistent preference for local solutions over shared platforms, suggests that the system is still in an early stage of the deeper change required. The leadership now needed is someone who can hold the long view without the luxury of sixteen years to wait for results, who can translate national infrastructure into local adoption, and who understands that the technology, at this point, is rarely the problem.
