Re: [IxDA Discuss] Define a functional spec

[Charusmitha Ram]

I would describe a functional spec as a contract between the product  
team and the development team that defines all the modules that needs  
to be implemented in the product so that the dev team can figure out  
the technical requirements.
This is NOT applicable for a truly agile model, is somewhat useful for  
a semi-agile environment and is quite essential for older traditional  
models. But I think the origin of a functional spec is from older  
models.
In semi-agile environments it is created in tandem with design  
documentation and updated as the design iterates. In older models it  
is created after the design phase is done. (obviously this is very  
inefficient).
