When a secretive organisation adheres to a set of principles, was created just to safeguard those principles, then should that set of principles be described as a manifesto, creed or a doctrine? I'm lost on the subtle differences when I look at dictionaries, thesauruses and Wikipedia.
This organisation is not religious, but would probably be recognized as a somewhat evil sect from the outside. They have not publicized any of these principles.
The principles are stated in the same style the Agile Manifesto was originally stated, but it is not made public:
Individuals and interactions over processes and tools
Working software over comprehensive documentation
Customer collaboration over contract negotiation
Responding to change over following a plan
I'm again getting confused however, as the above lines are now headlined as the Agile Values, rather than manifesto. Perhaps "values" is better than manifesto, creed or doctrine, but the connotation implies something public to me.
Then there are the words dogma and ideology. However, the principles are stated explicitly within the company, principles to live and die by. So the word should indicate a material list of principles within a secret sect-like organisation. It's a word the organisation itself uses to refer to it.
Some insight is greatly appreciated.
/edit: I notice I dodge around the issue by using the word "principle"; I'm not ruling that out either.
