Business critical models in the Ministry of Defence in 2020

Published 23 June 2020

We are publishing a revised list of the MOD’s business critical models as of 1 April 2020, as part of our response to the Macpherson Review of Quality Assurance of Analytical Models. We have continued to regularly update and publish a list of the Department’s business critical models on our website. The list of business critical models is expected to change over time as existing models are revised or retired and new models added. The list that has been published represents the most up-to-date version and supersedes any previously published lists.

Background

Following the problems in the award process for the InterCity West Coast franchise by the Department of Transport, Sir Bob Kerslake and Sir Jeremy Heywood commissioned a review of the quality assurance of analytical models that inform policy across government. The review was led by Sir Nick Macpherson, Permanent Secretary at the Treasury, who published his review of quality assurance of government models in March 2013.

How have we implemented the Macpherson Review?

As required by the Macpherson Review, our governance statement must confirm that we have an appropriate quality assurance framework for analytical models. Our governance statement is published in the Department’s Annual Report and Accounts. We also asked each Arm’s Length Body that has one or more business critical models to confirm their arrangements are appropriate in their annual Assurance Statement.

MOD has well established arrangements already. To further strengthen our processes and documentation - as well as our culture and the environment in which quality assurance takes place - we are implementing an Action Plan. For example, we are:

• embedding quality assurance of analytical models into the Standards workstream of the Department’s Analysis Function, which was launched in 2019;

• improving our governance arrangements, for example engaging with each area of the Department that produces analysis to ensure that they understand the requirements and that each business critical model has a Senior Responsible Owner;

• running a Quality Assurance Working Group for knowledge sharing and development of best practice;

• ensuring our processes and guidance are clear, cover quality assurance arrangements and available to everyone in the Department;

• promoting a pro-quality assurance culture, for example by using Modelling Champions in key organisations and, where appropriate, including quality assurance as a work objective for staff; and,

• promoting transparency by publishing a list of our business critical models.
