Service description

Assist aims to improve government communications through making Government Communication Service (GCS) members more efficient and effective in their roles. GCS identified an opportunity to enable government communicators to become more efficient in common daily tasks, such as writing communications plans. This unlocks additional time to be spent on other impactful tasks, including cross-government collaboration. Assist provides government communicators the ability to quickly produce first drafts, receive instant feedback on work and brainstorm ideas using Generative AI. The tool is underpinned by accurate and reliable GCS-specific guidance and resources. This helps ensure Assist’s outputs incorporate the profession’s best practice guidance and frameworks.

Things the service team has done well:

The team has done well to draw on a wide range of research data and insights from across the government to support their understanding of their users and how their users use artificial intelligence (AI) in different contexts. Their fast-moving cadence of conducting user research and gathering insights to inform and drive product iterations provides a high level of confidence, as does the way they prioritise features based on user pain points, such as the time taken to make first drafts of communication plans.

The team has stayed firmly in an achievable scope and focused on improvements that add genuine value to their users and overall government efficiency.

The team utilises all appropriate tools to iterate and make evidence-based decisions when building and improving the service. Multiple professions utilise the dashboards and data to collate and cleanse granular data. User data is complex and has been dealt with in a secure and safe way, while maintaining the quality of analytics to drill down into pain points and user issues. Qualitative and quantitative data is handled appropriately and securely and the team are aware of GDPR and PII (Personally Identifiable Information) data handling policies. Appropriate MI tools are used depending on the ask. A high level view of analytics is shared with departments and users on a scheduled basis to encourage digital take up and identify areas for improvement. KPIs are clear and well understood.

The team have proved that LLMs (Large Language Models) can help staff with their daily work and support an efficient Civil Service.

The team are working across government departments to share learnings, expertise and knowledge in this innovative area to support the wider Civil Service.
