Scalable Approach to Vulnerability via Interoperability (SAVVI)


The Problem

Local Councils need to identify vulnerable people and households, and then lead a multi-agency, and community response to assessing needs and providing support and interventions. This has involved blending attributes from data sourced from many local and national organisations. Councils have found that datasets containing vulnerability attributes need to be discovered and shared; attributes are hard to extract from many datasets due to inconsistent semantics, quality, and governance; matching datasets is imprecise due to inconsistent use of identifiers and lack of biographic standards; action tracking in real-time across many agencies requires a secure standards based ecosystem, rather than shared product.


At iStandUK, we’re excited to have been selected by MHCLG’s Covid19 Challenge to run a project to propose the data and standards that can improve how local councils can find vulnerable people and households, and then promote a coordinated multi-agency response.

MHCLG have teamed us up with a project led by Huntingdonshire District Council, where they have defined a risk model based on life events, to highlight where an early intervention can reduce hardship.

So we are working with Huntingdonshire now, to learn what data and standards they need to power their approach, and we’re reaching out to other councils to make sure that what we come up with supports other models too.

Since we launched at the end of August, we have appointed data experts from Bodvoc Ltd to support us. They are currently getting up to speed with the project and have been supporting our discovery work to understand the nature of the (data) problems that local authorities face when trying to identify the vulnerable within the communities we serve. Hugh Boyes, Director of Bodvoc Ltd said that “this is an excellent project to apply our data modelling and information management skills to assist councils to identify and support vulnerable residents”. The Bodvoc team includes experts from Data Performance Consultancy Ltd and STFC Hartree.

The discovery phase of the project is well underway; we are undertaking a series of workshops to understand the data requirements of councils in their work to identify vulnerable individuals and households.
