, standing for ‘a Scalable Approach to Vulnerability via Interoperability’, is a programme hosted by on behalf of the local public sector, and funded by the Department for Levelling Up, Housing and Communities’ (DLUHC) .
The COVID-19 pandemic highlighted a need for local authorities to identify vulnerable people and households so that they can formulate a coordinated multi-agency response. The purpose of the SAVVI project is to define - and encourage the adoption of - sector-wide data standards that will help local councils, and their partners, to improve their processes to identify vulnerable people, and target appropriate support to those in greatest need.
We are building on the experiences of the pandemic to present data standards, data sharing, and information governance, within a , that can be applied to ‘find, assess, and support’ people and households over a wide range of vulnerabilities.

What do we mean by ‘Vulnerability’

At SAVVI, we define vulnerability as -

‘An Increased Risk of a Poor Outcome’.

So, SAVVI is about using data to find people who may be at risk, and intervening with useful services to avoid those poor outcomes.
We have looked at vulnerabilities such as;
becoming homeless
coping during a flood
child poverty
The call these “Headline Outcomes”, with examples such as;
getting a good education
children safe from abuse and exploitation
crime prevention


The Need for Early Identification of Vulnerabilities

We are finding that there are often fracture points and gaps between services, which people can fall through. This results in their needs not being recognised and responded to.
According to early findings from the inquiry into ‘’ by the House of Lords Public Service Committee, a lack of a joined-up national strategy on vulnerable children and their families is undermining the effectiveness of various departments’ policies on child vulnerability, leading to duplication and diminished effect as different departments work towards their own policy ends rather than a shared goal. The Inquiry finds this lack of integration at the national level is inhibiting the ability of services and agencies to address the overlapping needs of vulnerable children. The decision by successive governments not to prioritise early intervention has led to poorer outcomes for many children, increased pressures on statutory services and higher costs due to late intervention and a loss of tax revenue.
For some vulnerabilities, such as ‘school readiness’, no single organisation is responsible. For example, many children living in families where abuse, mental illness or addiction are present, are not on anyone’s radar. Consequently, access to services can be based on an over-assessment of eligibility rather than a deeper redress of needs.

How SAVVI Helps to Identify Vulnerability Early

We are working with councils, programmes, and industry, to look at a range of vulnerabilities, such as homelessness, loneliness, financial distress, re-offending, school-readiness and so on. Traditionally, these have been looked at in isolation and the solutions are not linked. SAVVI is proposing processes, standards, and data sharing, to be both ‘scalable’ across many vulnerability themes, and interoperable across products and participants. The aim is early identification, and smarter interventions and referrals.
To drive ‘early identification’, we have to bring together data from a number of data sources. Often, the separate computer systems across many agencies struggle to interchange and match up data. We are testing a set of data standards to represent predictive indicators in a consistent ‘vulnerability attribute’ form, linked to a common format to represent a person or household.
SAVVI is also focused on providing real-time dashboards and outcomes frameworks, and the data analytics that will improve successful identification and support.

Helping the Sector Navigate Information Governance to Identify Vulnerability

The Information Governance to support ‘early identification’ is often cited as a blocker, so that initiatives fail when data cannot be sourced. We have put together the where we set out the steps to legally and ethically share data, for secondary use. Where a legal gateway cannot be found to support a data share, the framework proposes escalations, such as via the .
We are currently creating the ‘SAVVI Catalog’, where we list the data sharing propositions that we find, themed within the vulnerabilities that we are exploring. We lay out the data items, where they are typically found, and the legal basis on which they are being shared. Of course it is still for data controllers to reach their own opinions on what data to share, but bringing all these propositions into one place has been welcomed by the councils that we have worked with, who otherwise tell us that they don’t know where to start with a data project. We’d like to go further and create a single information governance portal that means that every part of the system understands the rules and follows them appropriately.

Interoperating with Other Standards to Direct Vulnerable to Support Services

Once cohorts of vulnerable people/households have been found, we need to be able to refer them, or at least signpost, to local support services and activities. SAVVI is working with the standard to build high quality directories of local services that can be queried to find potential solutions to assessed needs and circumstances. Interoperability here is based on common terminologies so that directories and referral engines can join up, to become an ecosystem for front-line professionals and for self-service use.

What We Are Doing Now

We are now in phase 3 of the project and in this phase the team are focusing on deploying SAVVI for real and making it self sustaining. Phase 3 consists of four interrelated workstreams of activity: Projects, Engagement Platforms, Adoption and Sustainability. You can find out more about each of the workstreams in the
