We know by books that: User stories should be Valuable, estimable, independend and so on...
We are newbies on all this SCRUM stuff, and we have arrive to the following feature / epic / backlog item:
"Accept reservations by SMS"
The problem is that, none of us knows nothing about SMS sending and receiving services at the moment.
We can split this into small user stories, and split it into:
As a Restaurant Owner, I wish to receive my website reservations by SMS on my phone, so that I can prepare the table for my customers.
As a restaurant site visitor, I wish to make a reservation so that I can be assured that I will have a table once I arrive on the restaurant.
But on both user stories, we still have a huge ??? factor.
Because we need to investigate HOW and WHAT are the technically features, before we can split those User Stories into something "Small, Valuable, Estimable, and so on..."
How can we deal with this?
We are thinking about creating on those USER STORIES, a TASK for "Investigate further". What say you?
