Clarifications on ISO/IEC 17025-requirements for laboratories
The above link is to the “official” ISO site providing “Clarifications on ISO/IEC 17025-requirements for laboratories”. For convenience, I've combined all of the “official” ISO 17025:2017 clarifications from ISO (as of January 2020) into a single zipped file.

European Accreditation - Application documents
Following the above link, navigate to the “Application documents” folder, and then to the “Documents to ISO/IEC 17025 and ISO 15189 - Laboratories” subfolder. In that subfolder, you will find several documents pertinent to ISO 17025. The most pertinent may be “EA-4/23 INF - The Assessment and Accreditation of Opinions and Interpretations using ISO/IEC 17025:2017”.

Process Flowcharting

"Business Process Model and Notation" (BPMN™) Standard

BPMN Quick Guide

Flowcharting Symbology / Conventions (Based upon ISO 5807:1985)

Note 1: While still valid, ISO 5807:1985 is extremely antiquated. Preference should be given to using the “Business Process Model and Notation” (BPMN™) standard for flowcharting your processes.

Note 2: The suite of BPMN symbols is included in all major flowcharting software programs (e.g., EDraw, Visio). Also, everal free and/or inexpensive online Flowcharting applications are available, such as:

Business Continuity Planning (BCP)

The “best” industry standard for BCP is:
NFPA 1600, “Standard on Continuity, Emergency, and Crisis Management”
https://www.nfpa.org/codes-and-standards/all-codes-and-standards/list-of-codes-and-standards/detail?code=1600

Although a government standard, another very good standard is:
NIST Special Publication 800-34 Rev. 1, “Contingency Planning Guide for Federal Information Systems”
https://nvlpubs.nist.gov/nistpubs/Legacy/SP/nistspecialpublication800-34r1.pdf

While ISO has produced ISO 22301, “Societal security — Business continuity management systems — Requirements”, once you dig through all of the required Annex L nonsense.. and the laughable incompetence of the authors, there are only a few gems buried in it. Similarly, ANSI/ASIS ORM.1-2017, “Security And Resilience In Organizations And Their Supply Chains - Requirements With Guidance” addresses this topic as well (although the ASIS_SPC.1-2009 version was better in some regards). However, it is too similar to ISO 22301 to be of any real value.

Ultimately, any company would be FAR better off simply purchasing a copy of “Business Continuity For Dummies” (which is actually quite good) than either of these two standards.
