Rationality and Product Preference

About a year ago, for fun, I went to grocery stores and bought as many different kinds of cola soft drinks as I could find, including:

Coke
Pepsi
HEB Original Cola
Safeway Select Cola
RC Cola

I then proceeded to administer blind taste tests to guests whenever I had people over to my loft. The results were interesting, mainly because what people thought was their favorite cola differed greatly from their actual preference.

Safeway Select Cola performed best overall. Unfortunately, I can no longer find it at the Randall's stores where I originally bought it.

I administered this test to only a few people (about six, if I recall correctly), so take the results with a grain of salt. But chalk this anecdote up as another example of how customers have all sorts of prejudices that interfere with knowing what they really like.

Why Spreadsheets Suck for Prioritizing

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 ...
