To guide, develop, and promote the practical usage of alternative data sources (including scanner, web scraped and administrative data) in consumer price statistics, the specific objectives of the Task Team are as follows:

Specific Objectives:

• Repository of information. Provide guidance on the end-to-end methods and processes of using these data. The guidance should reference existing literature where possible.
• New guidance material. Provide methodological guidance for those topics where existing literature does not exist or does not fully capture the different range of possible options for consideration.
• Practical implementation. Provide practical guidance on the implementation of these methods and processes in a live production setting.
• Training. Provide a full suite of training materials to supplement the guidance produced above.

These objectives will be supported by two underlying principles:

• Timeliness. Ensure that any content produced by the Task Team in line with the above objectives remain up to date with current discussions in the field. For this objective, the Task Team will be supported by a Secretariat function which will be responsible for maintaining the existing published content.
• Informed choice. Provide a range of options for these topics, so we should not recommend a single “best” approach - instead colleagues will be encouraged to review the options and decide what is best for their particular situation.

1. Standards and frameworks: Publish and maintain guidance on utilising new data sources in the production of consumer price statistics. Guidance to be structured in a form most applicable to support NSOs, including but not limited to an evergreen handbook, approaches to reproducibility, example code, etc.
2. Capacity building: Publish and maintain training content aligned to the handbook guidance, covering the end-to-end process of using these new data sources in the production of consumer price statistics.
3. Research and innovation: Identify gaps in the existing literature and publish additional guidance as appropriate.
4. Collect feedback from the community: Present the work of the Task Team via established networks and conduct surveys to help shape guidance and support the planning of future workstreams.
