Legacy SAP Data Archiving Full Business Case

The purpose of this report is to obtain a Delegated Officer Decision to procure a 3rd party data archiving solution based on confirmed costs, which have been updated following the completion of a procurement process. The procurement process formally commenced in March 2021 having completed required preparation and gaining a Delegated Officer Decision to proceed, which was approved on 29th September 2020. This further Delegated Officer decision is required prior to contract award as the confirmed cost of the solution is greater than 5% higher than the projected cost estimate in the original Delegated Officer Decision report.

The data archive solution will provide long-term storage of 16 years of historic data held in the council’s corporate system, SAP.  SAP is the system that the council currently uses to manage its business-critical finance, procurement and HR & payroll processes - however it will be replaced by the Unit 4 system in Dec 2021.

The historic SAP data is required to be retained for operational reasons and will be subject to GDPR.  Alternative options to retain the historic data on SAP or migrate it to the new Unit 4 system (the SAP replacement) were rejected by Strategic Programme Board in 2020 because the hardware where the SAP system is installed has reached end of life, and it would be prohibitively expensive to fix;  also, as this legacy data is not required for the day-to-day running of the future organisation, it would be sub-optimal to migrate it to the new Unit 4 system (due to the impact on future storage costs and system performance).

The original business case cost estimate of the data archive project was £414k in total for 5 years (2021/22 – 2025/25).  This was based on high level estimates provided by suppliers informally and was included within the overall Digital Business & Insights full business case, which was approved by Cabinet in July 2020. 

A procurement process was initiated and an invitation to tender (ITT) for the 3rd party archive solution was issued via a Crown Commercial Services framework to several suppliers.  The successful preferred supplier’s bid was the most affordable and met all mandatory technical requirements.

The new revised data archive project cost is £570k over 5 years, this incorporates the preferred bidder’s pricing estimates, and the latest Surrey infrastructure costs.  The cost is 38% higher than the original business case estimate of £414k because the preferred bidder’s quote is significantly higher compared with the original non-binding informal quote; and the infrastructure costs are higher as the technical delivery costs have been re-estimated now that the chosen solution is known. 

Following Delegated Officer approval, the project will award the contract to the preferred bidder and look to deliver the implementation of the data archiving solution for go-live in Q4 2021/2022. This go-live timing will follow the Unit ERP system go-live in December 2021 and will enable the council to decommission the existing SAP system.
