Time to MarketDue to globalization effects, and other economical changes, the time to market over time decreased significantly

Why does that matter?


Defined Process ControlThe time required to complete a repeatable action is a valid proxy to predict time to complete

Empirical Process ControlEvery step performed while creating a new product is unique, only outcome can be trusted


The Product Vision... Why?


The vision that inspired a nation.

A statement that had an entire nation striving for the same goal.


Moon Shot"I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the Earth." !

— Pres. Kennedy, May 25, 1961


We choose to go to the moon…“We choose to go to the moon in this decade, not because that will be easy, but because it will be hard -- because that goal will serve to organize and measure the best of our energies and skills -- because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win.”

for <target customer> who <has a specific need> the <product name> is a <product category> that <key benefit> unlike <list of competitors products> our product <additional benefits>


for music lovers, who want to listen to their music wherever they go, the iPod is a digital music player, that allows to bring all your music in your pocket unlike traditional CD players, our product will contain 5000 songs, will last days on battery and will allow to sync all your music from the PC to the iPod in minutes


Do we understand WHY we are doing this?

The Vision sets a common direction for the Project, every participant needs to understand and share it, to be able to contribute effectively, and be motivated…

Feature Name (title)

1. Opportunity 2. Customer SegmentsWhat is the problem to be solved? What type of customers & users will

benefit from this solution?

How is the customer solving the problem right now?

3. Possible SolutionWhat are the key points of a possible solution to the presented problem?

4. BenefitsWhat are the benefits for the customers?

What are the benefits for internal stakeholders?

6. Measuring SuccessWhat metrics will be best measure the success of the feature?

5. Business ReadinessWhat steps are required from the business side to be able to use this capability?

7. Cost of DelayWhich profile better represent the cost of delay (CoD)?

8. Costs StructureHow does the cost structure look like for such a feature? One time, ongoing costs, contractors expenses, development costs?

9. Value to Customer and BusinessWhat are the expected incremental revenue for selling this feature, and what are the strategic and tactical benefit? What are the intangible values (usability, performance, customer knowledge obtained...)

It will contain 5000 songs

Current digital music player can only hold up to 20 songs

Re-sync their music frequently

- Jogging lovers - Bicycle riders - Music Professionals

- media store 1000+ songs

- fit in a pocket - compression

- no need to sync often

- change mood change song

- playlists

- addressing a new market

- micro engineering

- partnership with component builder

- sales channels - Packaging - Agreement with Music Firms?

- Hardware development cost - SKU costs target $170.00 - 3rd parties licenses for digital music

- Usability with one hand - Long battery life - All songs you own in one place

- store 1000 songs (HQ)

- 1000 early adopters/week on 1st monthHow Can

we test

this?

Do we understand and agree on WHAT are the needs?

A Lean Canvas serves as a container to represent a specific need, and allow to have a structured conversation with the stakeholders, and agree on the objectives…


User Stories... How?


Agile Teams normally work with User Stories to agree what needs to be built and how…As a runner I want to be

able to store all of my songs on the iPod, so that I will not have to chose which songs to bring with me when jogging


- I own around 1000 songs, and I want them to fit in - I want to have good quality

User Stories do have Acceptance Criteria on their back, Team wouldn't commit to them, without knowing how to get them done!


Solutions emerge as a result of the User Stories conversation within the team…


Do we know HOW to solve these needs?

The easiest way to share a solution and create a common understanding is to be able to describe the User’s needs. User Stories are a very powerful and yet simple tool to facilitate that key conversation to happen…


How would we know when we are DONE?


How can we learn what needs to be fulfilled? How can we keep the focus on it?- I own around 1000 songs,

and I want them to fit in - I want to have good quality


“Scenario” Given <context> When <action> Then <expected result>

- I want to be able to sync a song with a click - I want to add the song to my “Favorite” playlist

Scenario 42: Sync a song with a click Given I have selected the song on iTunes and my iPod is connected to my Mac When I press the sync button Then I expect the song to be transferred on my iPod and I expect to see a confirmation message in iTunes

Adapting vs. Defining“At the University of California at Irvine, ... they just planted grass... they waited a year and looked at where people had made paths in the grass and built the side walks there.”

Delivering fast requires new methods... and new tools

People need to learn new tools and new practices...

Agile Engineering Practices

There is no “perfect” tool and there is no tool forever...

and have the courage to leave behind the Old tools which are not supportive anymore


Community of PracticeLearning as Doing... Learning as Belonging... Learning as Becoming... Learning as Experience


BacklogDefinition of Ready

Definition of Done

Shippable Product


Now that we know we are DONE...

we can look back to our original need an have a Confirmation that the solution we implemented is the right one to fulfill that need...


so what?

1. Agile development allows to accelerate the feedback loop and validate assumption faster



2. Don’t fear to fail, create safety containers to enable learning faster from failure, and adapt…



4. “Perfection is achieved not when there is nothing left to add, but when there is nothing left to take away” – Antoine de Saint-Exupery



3. “Delivering the right thing requires iterating, trying to get it right the first time… it’s foolish!” - Andrea Tomasini
