===== Joining the Group ======
We are on the [[https://snowmass2021.slack.com/archives/C012476LS15|#compf05-useranalysis]] channel in the [[https://snowmass2021.slack.com/|Snowmass Slack]], and important announcements are sent via snowmass-compf5-useranalysis[at]fnal.gov (subscribe via [[https://listserv.fnal.gov/scripts/wa.exe?SUBED1=SNOWMASS-COMPF05-USERANALYSIS|this link]]).

The Indico category that includes our meetings is [[https://indico.fnal.gov/category/1107/|here]].

===== Topics for Letters of Interest & White Papers =====
Community input is a critical part of the Snowmass process. We encourage [[https://snowmass21.org/loi|letters of interest (LOI)]] and [[https://snowmass21.org/submissions/start|white papers]] discussing the following (non-exclusive) list of topics relevant to end-user analysis:
  * Hardware for analysis facilities
  * Use of accelerators
  * Analysis libraries
  * Data storage formats & dataset bookkeeping
  * Programming languages
  * Software for collaboration: version control, messaging
  * “Real-time” analysis
  * Long-term reproducibility and preservation

Please consider the following aspects when preparing LOIs and white papers. 
  * Sustainability, both technical and human
     * Documentation
     * Training
     * Long-term software support & development
     * Integration with the broader ecosystem
     * Broad applicability to the field
     * Hardware facility evolution
  * Interaction with other scientific fields & industry
     * Role of proprietary technology
     * Potential contributions to computing outside HEP
  * User experience
     * Ease of use & setup
     * Scalability of technologies
     * Required training and broad applicability of training to other domains
     * Accessibility


===== Description=====
  * Functional areas
    * Making plots and tables
    * Statistical tools
    * Making it easier for users to analyze data (single namespace, data delivery, … )
  * Mandate
    * Define end user analysis and describe the end user analysis needs of the stakeholders
    * What are the end user analysis resource needs and performance needs of the stakeholders?
    * Coordinate tightly with “Storage and processing resource access” working group, do we need to integrate data aggregation more tightly into the data layer?
    * What are technology solutions (both hardware and software) that are or will be used by the stakeholders?
    * What is the evolution of these technologies?
    * How are these solutions embedded in industry solutions or solutions used by other science domains?
    * questions about statistical tools, to be filled
    * Ensure balance between ROOT/C++ experts and new technology experts
    * version control ♦
    * slack and similar tools
    * ZOOM, Skype
    * What tools are used/needed by the stakeholders to develop code collaboratively, to communicate?
    * How is the intra stakeholder communication working, how will it work in the future? 
    * Proprietary software, licenses ♦
    * VMs, containers ♦
    * Integration of external packages into experiment software stacks 
    * What are other science domains using, what is industry using? 

Items marked with ♦ are also being considered by [[https://snowmass21.org/computational/preservation|CompF8: Reinterpretation and long-term preservation of data and code]].  Our groups will discuss these items once we have identified needs within our individual working groups.
