Stavo cercando qualche informazione in più su come pianificare, in un progetto agile, le iterazioni e le user story per ogni iterazione e su come stimare i tempi. Ho trovato su YouTube il talk completo di Mike Cohn su “Agile Estimation” fatto a Marzo del 2007. Vale la pena ascoltarlo anche se è lungo 90 minuti.

Da qui potete scaricare le slide del talk.

Inoltre, molto interessante è anche questo post di Mike Cohn sugli Story Points. Lui ritiene che non dovrebbero essere usati come misura di produttività:

Using story points or ideal days to measure productivity is a bad idea because it will lead the team to gradually inflate the meaning of a point when trying to decide between calling something “two points” or “three points” […]
My view is that points can be used as the best way to estimate and assess progress that we’ve ever had or they can be used as another weapon with which to hit the team […]

E ci sono tanti altri post interessanti sul suo blog, come questo:

A common source of confusion on agile teams occurs when the sprint (“iteration”) backlog and the product backlog are both estimated in hours. To avoid this confusion I strongly recommend estimating these backlogs in different units.
In sprint planning the team should always talk of tasks and hours. Sprint planning covers the horizon of typically two to four weeks out.
In release planning the team can choose between “ideal days” and “story points”. Regardless of which they choose, they still do sprint planning in hours […]

[…] I don’t use story points for sprint planning because story points are a useful long-term measure. They are not useful in the short-term […]
