"Delivering Product"

In a previous entry, I mentioned that, when you use an agile product development process, you deliver "a working version of the product for review" at the end of each iteration. I mentioned in a later entry that Alistair Cockburn criticizes organizations that claim to use agile methods but don't deliver product at the end of their so-called iterations.

What does it mean to deliver a working version of your product to customers? What is the point of iterating if you "deliver product" after the first iteration?

The crux of the matter is that you should be able to demonstrate at the end of an iteration how a customer would use your product to address customer problems. So "working version" doesn't mean one that is ready for sale to the customer, but just one that is ready for demonstration. For a software product, that demonstration might include showing some hard-coded mock-ups in place of screens developers haven't yet implemented.

The key here is that you deliver something which enables learning. That could be product to customers, betas or prototypes to select customers, or something to stakeholders.

Regardless, the litmus test is - did you learn something which caused you to change what you're doing (or how you're doing it)?

Exactly. Learning and nimble adjustments based on what's learned.

As I mentioned in the previous blog entry, Agile Product Management developers can learn from discoveries during design and implementation. Perhaps more importantly, product managers can discover requirements they hadn't previously considered (particularly requirements corresponding to problems to avoid, not just problems to solve).

This learning can take place regardless of whether we deliver the product to internal or external stakeholders. The feedback or behavior of external stakeholders that are actual target users can in many cases be more reliable. But it's not always necessary.

With lean startup methods, we cast a wider net: a learning loop that encompasses the entire product strategy (including marketing and sales).

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

Stop Validating and Start Falsifying

The product management and startup worlds are buzzing about the importance of "validation". In this entry, I'll explain how this idea originated and why it's leading organizations astray. Why Validate? In lean startup circles, you constantly hear about "validated learning" and "validating" product ideas: The assumption is that you have a great product idea and seek validation from customers before expending vast resources to build and bring it to market. Indeed, it makes sense to transcend conventional approaches to making product decisions . Intuition, sales anecdotes, feature requests from customers, backward industry thinking, and spreadsheets don't form the basis for sound product decisions. Incorporating lean startup concepts , and a more scientific approach to learning markets, is undoubtedly a sounder approach. Moreover, in larger organizations, sometimes further in the product life-cycle, everyone seems to have an opinio

What Product Managers Can Learn from the Apple iPod

The Story When Apple unveiled its iPod digital music player back in October 2001, I dismissed it as a  parity product . I already owned the Cowon iAUDIO CW100 MP3 player, loaded with my favorite tunes. There was Apple, generating great hype over the iPod as if it were a breakthrough product. The idea of a portable digital music player was nothing new. The first mass-produced MP3 players came out in 1998. In late 2001, the concept may have been new to a lot of Apple customers, but it wasn't new to me. I proudly showed my MP3 player to friends when they gushed about the iPod. Thus Apple's iPod was not an innovative product in and of itself. Years later, however, I realized the significance of ecosystem of which the iPod was a part. Apple had released iTunes (with technology purchased from  SoundJam MP ) and created the iTunes Store for finding and downloading music. Unlike Napster , it was a safe and legal way of distributing and acquiring music. The prior way of playing
