User Stories

Let's see how some folks define "user story":

"A user story is a very high-level definition of a requirement, containing just enough information so that the developers can produce a reasonable estimate of the effort to implement it. A good way to think about a user story is that it is a reminder to have a conversation with your customer (in XP project stakeholders are called customers) . . . . [U]ser stories are small, much smaller than use cases. In XP a user story must be able to be implemented by two people in a single iteration/cycle, therefore if you’re working in one week iterations each user story must describe less than one week worth of work."

A user story is thus similar to a use case but "smaller". It's smaller in the sense that it should be possible to implement within a short period of time. The final product that you deliver to customers will be the result of implementing many such user stories.

Therein lies a challenge: along what lines to you divide the user stories so that they are each sufficiently small? I'll explore the alternatives in a future entry.

Some see her unpredictably changing the direction of her rotation. Supposedly, people who see clockwise rotation are right brained. People who see counter-clockwise rotation are left brained. I originally came across this animation here .

Why Spreadsheets Suck for Prioritizing

The Goal As a company executive, you want confidence that your product team (which includes all the people, from all departments, responsible for product success) has a sound basis for deciding which items are on the product roadmap. You also want confidence the team is prioritizing the items in a smart way. What Should We Prioritize? The items the team prioritizes could be features, user stories, epics, market problems, themes, or experiments. Melissa Perri  makes an excellent case for a " problem roadmap ", and, in general, I recommend focusing on the latter types of items. However, the topic of what types of items you should prioritize - and in what situations - is interesting and important but beyond the scope of this blog entry. A Sad but Familiar Story If there is significant controversy about priorities, then almost inevitably, a product manager or other member of the team decides to put together The Spreadsheet. I've done it. Some of the mos...

5 Ways Companies Make Product Decisions

In the last blog entry, we reviewed the  four problems that companies face, or are trying to overcome, as they make product decisions .  Now we'll look at the ways that most companies make their product decisions. Companies that develop, market, and sell products and solutions make strategic and ongoing tactical decisions.  They decide what features to include in their products, what messages they will use to communicate the value of their products, what marketing tactics they will use, what prospective customers they will target, and many day-to-day choices. Whether or not these decisions are deliberate or ad hoc, most companies use some combination of the following ways of making product decisions. (A downloadable "map" that summarizes the product decision landscape is included at the end of this article.) Customer Wants Product decisions based on feature requests, focus groups, and what prospects and customers say they want. Companies are selling products to ...
