Well today I made this after finishing my work on Riot Music (finally) and starting on refurbishing Idol+V4mirai. This is essentially just a visual reminder for myself of the different variations agencies can have depending on how they're organized and it looks neat so I might as well share it.
I took a very simple project (Egous) which has no branches or generations (yet) and only 3 talents and remade it to look like it would if it did have one or the other or neither. All of these variations are more common than you think even though people are very used to the classic Holo/Niji "AGENCY->BRANCH->GENERATION/WAVE".
The naming is an issue too so I have resorted to my own internal nomenclature of tiers:
Management Tiers
TIER I: Corporation Level (Includes: Parent Corporations, Holding Companies. Example: Cover Corp)
TIER II: Company Level (Includes: Companies, Subsidiaries, Management Organizations. Example: Hololive Production)
TIER III: Agency Level (Includes: Agencies, Projects, Labels, Companies, Brands. Example: Hololive)
Talent Tiers
TIER IV: Branch Level (Includes: Branches, Projects, Groups, Labels, Sub-labels. Example: Hololive EN)
TIER V: Generation Level (Includes: Generations, Waves. Example: Myth)
Of course these tiers are a bottomless barrel of exceptions. But to qualify for the chart, an entity needs at least a management tier and a talent tier. And an org can obviously have more than 5 tiers, though I have never come across any so far.
To make it more complicated there's also other conditionals, like pseudo-, which only applies to Tier IV. Defunct, which can apply to basically anything, and Tier downgrades/upgrades, which can happen when branches dissolve and merge, in which case a Tier IV downgrades to Tier V (Nijisanji ID and KR). Or when a part of a branch gets made into its own group, in which case it upgrades from V to IV (Meteopolis -> Cho Ginga).
