The Feature Funnel: The Big Picture

Busy day today so just a short post.

I spent some time visualising the ideas that I have been discussing in my series of posts on the feature funnel and came up with this representation.

So far I have discussed the wishlist, popularity and ambiguity in my posts. The other aspects of the feature funnel will be discussed in later posts.

The order of the filters applied to the wishlist is significant.  Focus on popular features first, then remove ambiguity so that the features are fully understood.  Once features are understood, alternative features that achieve the same goal but in different ways are explored. Promising alternatives are included and the expanded set of features is checked for conflicts and dependencies.  Finally features are checked for their feasibility. The different aspects of feasibility are summarised using the acronym TESCO.
