About the work

Why the work is being done
The Address Index being developed under this beta will be used to underpin the 2021 census and statistical work across ONS. The development is of an address referencing service and includes tools to manage and match complex address data. We estimate the development to deliver the Minimum Viable Product will be around 6 months.
Problem to be solved
Tools to allow management and matching of address data; building a matching & querying service; (controlled) access to stored address data and the matching service via an API Gateway, expanding the use of the index to include attribute data (information about each address), linking to Business Index data.
Who the users are and what they need to do
Users are initially ONS business areas including census - but options for wider use of the service by other government departments are being investigated. Users will be able match individual addresses and batches of addresses as well as extract samples and frames from the data store.
Early market engagement
Any work that’s already been done
The Address Index is now moving into Beta Phase. During Discovery and Alpha we have delivered an agreed technical stack and built functional products around query and matching using multiple data sources.
Existing team
The team will work with a range of internal product managers who are subject matter experts in index and register development. Currently the team has been assigned an ONS Delivery Manager and an ONS Business Analyst to work alongside the supplier, it is envisaged that two ONS Software engineers will be assigned in August to work alongside the supplier.
Current phase

Work setup

Address where the work will take place
The Address Index staff will be located in our Titchfield Office in Fareham Hampshire. It is expected the team will be co-located at this location but willing to travel between our Titchfield and Newport (Wales) locations and potentially other governments departments as required.
Working arrangements
The team will be expected to work alongside internal resource to build and develop the required products. Integrated into the supplier agreement will be a knowledge transfer during the transition to a more permanent operating model. The teams will be co-located and expected to work on-site for a five day working week with some flexibility built in for travel arrangements. The teams will be expected to work within an Agile Delivery environment and be able to coach and mentor internal staff.
Security clearance
All members of the supplier team must be SC Cleared to the required Civil Service Standard prior to commencing contractual work.

Questions asked by suppliers

1. What team size are you expecting - and can you clarify budget range, which are two heavily linked questions.
The size of the team has not been agreed but from an organisational perspective we like to work with teams of 7-10. On the Address Index there is likely to be a blended approach using internal and external resource. No set costs have been agreed for delivery of the Beta phase, however we are aware of current market rates for the approximate team size we are looking for and applications will be looked at on cost, value and quality basis.
2. Were any external suppliers involved in delivering the Discovery/Alpha? If yes, how will ONS ensure a level playing field for this subsequent procurement?
The Discovery and Alpha stage was delivered by our current external suppliers. All applicants will be assessed using the same scoring matrix against the competencies required in compliance with the Digital Marketplace procurement rules and regulations.
3. You have two locations (Titchfield and South Wales) and modern DevOps projects are commonly carried out across multiple locations. Are you willing to drop the onsite requirement so that the work can be undertaken in the EU in Central and Eastern Europe? It would save tax payers lots of money & provide access to skills without a degradation in service.
The supplier team for the Address Index will need to be co-located in our Titchfield Office in Hampshire with some occasional travel to Newport (Wales) and other government departments. Due to the level offsite stakeholder engagement and knowledge transfer to internal staff during Beta these are essential criteria. Although we are flexible on ad-hoc days away from the locations as agreed.
4. Please can you confirm what level of security clearance is required? Is it BCSS or SC? We can obtain BCSS clearance by XX/XX but ONS will need to apply for SC on our behalf and there will be a lead-time while it is obtained before our people can be onsite. Or can they be onsite pending SC clearance?
The level of security required is SC. ONS would sponsor the successful individual and process any new applications or invoke a transfer of existing clearance from another government department. to enable onsite working. Onsite working without SC clearance is permitted in special circumstances while the process is being completed, however if an individual failed to gain the SC clearance then they would be potentially removed from the environment.
5. Will the present external suppliers be eligible to bid for the Beta stage of this programme?
Yes the current external suppliers will be eligible to bid for the Beta Stage
6. Are there any outputs that you can share from the Discovery and Alpha stage?
The discovery phase identified initial user stories but the requirements have developed during alpha.

The alpha stage :

Developed an address matching function to test standard delivering proof of concept for single and bulk matches (as outlined in the tender document)

Agreed the technology stack (which is reflected in the essential experience criteria section of the procurement tender document)

Developed query and extract services to test standard
