1Define Your Needs

User Stories

As a <type of user>, I want <some goal to do something> so that <it

brings me some value>

SMART User Stories

SpecificMesurable

AchievableRelevant

Time Bound

I want a search field to search based on the firstname and lastname

As a community manager, I want to search in the customers list so that

I can see what previous conversations I've had with them

Prioritize2

Dimensional Planning

Idea: If complete version of a functionality is impossible, a simple version can be super easy

Goal: Increase project throughput and shorten the feedback loop

3+1 dimensions: time, resources, scope and depth

Dirt Road

Barely viable product level Take what you need then

throw out a third

Paved Road

Sober but robust implementation

Asphalt Road

Full implementation You probably don’t need features implemented at

this level

Flying Cars

SCI-FI ultra cool things So cool that you’ll never

implement them

Poker Planning

Idea: It’s the discussion and not the number that matters

Goal: Mesure the relative complexity of a user story compared to another

We’ll ask for estimates

Find your team maximum workload
