There are clear indicators of successful experimentation programs. The biggest of these is how an organization manages the documentation aspect of their experimentation program.
Experimentation documentation cannot be an afterthought. There must be a clear strategy and plan behind it to ensure it is valid and useful to the organization. A spreadsheet is not a strategy. Neither is hooking up random project management tools together with APIs in your spare time.
What will separate a lot of organizations running mediocre and poor experimentation programs from those that do it well is how they view and structure documentation as part of their experimentation process.
