Danish to English Other International Org/Dev/Coop

The phrase appears in a monitoring report about development work in Africa, e.g., on the cover as "Stort koncept" as part of the title and "Normalt påkræves det at XXX’s medlemsorganisation også deltager på en monitoreringsrejse efter det store koncept."

I have a feeling it might be internal jargon employed by the organization in question, but I thought I'd check here first.

Please don't submit "great concept" or "large concept" or "big concept" as an answer unless you can link it to some idiomatic usage in this context.
