At the turn of the millennium, local government in England and Wales employed roughly two million people across 411 local authorities. Every one of those councils was delivering essentially the same portfolio of 700 services to their residents. Bin collections, planning applications, social care, housing, environmental health, yet they were doing so in almost complete isolation from each other.

The same policies were being written in parallel in neighbouring councils. The same guidance documents were being developed from scratch in a dozen authorities simultaneously. The same operational solutions were being reached, independently, at significant cost, over and over again.

A Problem That Had Always Existed

This was not a new problem. It was a structural feature of the local government system itself. Highly decentralised, locally accountable, with few formal mechanisms for the kind of knowledge exchange that would allow one council to benefit from another’s hard-won experience. The result was a vast, invisible waste embedded in the fabric of UK public services, not through incompetence, but through the absence of infrastructure for collective intelligence.

The Improvement and Development Agency (IDeA), in developing a knowledge management strategy for the sector, plainly identified the problem: the knowledge was distributed across thousands of skilled officers and teams. What did not exist was a way to connect it. Two million professionals were each working largely in the dark about what their counterparts had already figured out.

The Answer from Academia: Communities of Practice

The theoretical foundation that would shape the solution came not from information technology but from social science. The work of Etienne Wenger and Jean Lave on ‘Communities of Practice’.  Their observation that practitioners in a shared domain naturally form groups to learn together, share experience, and build a collective body of knowledge, provided both the conceptual framework and the practical vocabulary for what IDeA set out to build.

The insight was to operationalise this at scale. Not to mandate knowledge sharing from the top, but to create the conditions under which it would happen naturally: a platform where communities could form around genuine practice needs, where the value would be immediate and practical, and where the barriers to participation would be as low as possible.

Launch: 300 Communities, 10,000 Users

The Communities of Practice for Local Government platform launched in 2006. Within months, the numbers told their own story. Over 300 communities of practice were active, representing 10,000 users across 410 councils. This was not, crucially, a technology project that had produced a platform and then struggled to attract users. The demand was already there; it had simply never had anywhere to go.
What the platform offered was deceptively simple: a neutral, cross-organisational space where public servants could find each other, ask questions, share documents, and build relationships with colleagues they would otherwise never have met. For a sector where every authority faces essentially the same challenges, this was not a luxury. It was a genuine efficiency lever that had been missing for decades.
 

The Communities of Practice platform that launched in 2006 would go through many transitions, it would become Knowledge Hub, nearly close, achieve independence, and eventually become part of Placecube. But the founding question that drove its creation has never changed.

And twenty years of evidence suggests that the answer is more compelling than even its architects anticipated.
