Review of the data systems for Public Service Agreement 20 led by the Department for Communities and Local Government: ‘Increase long term housing supply and affordability’

Introduction

PSAs are at the centre of the Government’s performance measurement system. They are usually three year agreements, set during the spending review process and negotiated between departments and the Treasury. They set objectives for the priority areas of government’s work.

PSA 20 is led by the Department, with data used to calculate the indicators provided by a wide range of sources including the Office of National Statistics (ONS) and the Citizenship Survey. Each PSA has a Senior Responsible Officer who is responsible for maintaining a sound system of control across Departmental boundaries that supports the achievement of the PSA. The underlying data systems are an important element in this framework of control.

The most recent public statement provided by the Department of progress against PSA 20 was in the 2009 Autumn Performance Report.

The purpose and scope of this review

The Government invited the Comptroller and Auditor General to validate the data systems used by government to monitor and report its performance. During 2008-09, the National Audit Office (NAO) carried out an examination of the data systems for the Department’s PSA. This involved, for each individual data system, a detailed review of the processes and controls governing:

  • The match between the indicators selected to measure performance and the PSA. The indicators should address all key elements of performance referred to in the PSA;
  • The match between indicators and their data systems. The data system should produce data that allow the Department to accurately measure the relevant element of performance;
  • The selection, collection, processing and analysis of data. Control procedures should mitigate all known significant risks to data reliability. In addition, system processes and controls should be adequately documented to support consistent application over time; and
  • The reporting of results. Outturn data should be presented fairly for all key aspects of performance referred to in the target. Any significant limitations should be disclosed and the implications for interpreting progress explained.

Our conclusions are summarised in the form of traffic lights. The ratings are based on the extent to which departments have:

  • put in place and operated internal controls over the data systems that are effective and proportionate to the risks involved; and
  • explained clearly any limitations in the quality of its data systems to Parliament and the public.

The findings from the 2008-09 validation exercise (PDF – 203KB) were reported to the Department in February 2009 and cleared with the Department in June 2009.
