Sally Davis initiated and led the creation of The Derby House Principles to promote diversity and inclusion in professional Wargaming. This was done in collaboration with other editors of PAXsims: a professional gaming blog with international contributors from governmental organisations, universities and the private sector. The principles were created in response to abusive online behaviours towards minorities within the Wargaming community. The principles embody a commitment to making Wargaming a more diverse and inclusive environment, with the aim of challenging and changing the culture within Wargaming. 
In Sally’s own time, she authored the Derby House principles and brought them to the attention of Dstl, which contains the Defence Wargaming Centre, for organisational endorsement. Sally shared the principles and started a conversation on our social business software Distillery (Jive) that has engaged Dstl’s workforce like no other D&I initiative before it. 
Sally designed a pin badge for people to openly show their enthusiasm and personal commitment to these diversity and inclusion principles. She launched a survey to understand minority experiences, which along with anecdotes shared directly to Sally, enabled her to create an interactive card deck of Women’s & Minority Experiences. This is providing a way for our people to engage with the situations experienced within Dstl and across MOD. 
From Sally’s lead, Dstl has publicly endorsed and strongly believes in these principles, encouraging everyone to adopt them in their daily life whether they are a wargamer or not. Industry, academia and government departments have also endorsed the Derby House Principles worldwide.
