Story mapping

When tackleling an objective it is necessary to make a good previous study

• Have the objective clear
• Define strategies to accomplish the objective
• Make tactical materialization proposals

We must have a "model" for our application, in order to know which type of client are we dealing with and their main characteristics.

It is recommendable that proposal meets INVEST:

• Independent: they can be implemented in any order
• Negotiable: details can be discussed between all parts
• Valuable: must provide value to the user
• Estimable: it doesn't have an excessive complexity
• Small: can be materialized in a short time
• Testable: we can make tests to verify it works properly

All objectives must be measurable through KPIs.

Establish priorities

We must value the priority of the strategical and tactical proposals through ICE:

• Impact: how much is it going to affect in the evolution of our project
• Confidence: how confident do we have that it will be successful
• Ease: complexity of their development

Each of them has a value of 0 to 10. Priority is obtained from the sumatory of them all. With this, we can establish a Minimum Viable Increment. The higher the value, the more a quick win it will be.

Three friends

It is referred to the 3 primary perspectives to examine before, during and after the development phase of an increment iteration.

• Business: which new value I want to provide?
• Development: How to build a solution for this requirement?
• QA: given that new value, how can I test it? given that solution, what could happen?

We share an understanding of the requirement and we identify possible confusions and disagreements.
