Business Analysts sometimes wonder where they fit in a cross-functional agile team. How do you get from a vague and amorphous business problem to a collection of user stories that the team can incrementally implement? Chris and Antony show how Business Analysts can use their existing skill sets to find the questions for the "unknown unknowns", the answers for the "known unknowns" and how to spread the shared understanding of the "known knowns". They will demonstrate how examples can be exchanged to evolve the shared understanding of the domain, how modelling helps uncover gaps in that understanding and how to incrementally communicate this understanding to the people implementing the product.

Agile Business Analysis

So, what is it?

What is Business Analysis

• Understanding the business value sought• Understanding the problem domain• Exploring the roles, incentives and required

product capabilities that solve the problems• Facilitating growth of that understanding

among others

What is Agile Business Analysis

• Accepting that we can’t have 20/20 foresight• Evolve everyone’s understanding of the value

& problem as the team evolves the solution• Working in small product increments• Remaining fully engaged on a project through

to delivery – why?

Feature Injection

• Feature Injection helps us incrementally and Iteratively:– Discover the real business value– Explore the problem domain– Explore the roles, incentives and required product

capabilities– Evolve’s everyone’s understanding of the problem

as the solution also evolves

Understand the Business Value

“Users ultimately dictate solutions to us, as a delta from the previous set of solutions we’ve delivered them. That’s just human psychology – writer’s block when looking at a blank page, as compared to the ease with which we provide ‘constructive criticism’ on somebody else’s work.” – Udi Dahan

Aim to understand…

• That which helps achieve the business value:– Who will use the product? (roles)– What do we need them to do? (behaviours) – Why would they want to do it? (incentives)– How are user behaviours exhibited? (examples)

As these things solidify, we can pull “business value increments” (BVI) into a structure that makes it easy to incrementally deliver these in our product

We now have an understanding of…

• Value: What is our motivation?• Roles: Who will use our product?• Behaviour: What do we need them to do?• Incentives: Why would they want to do it?• Examples: How are user behaviours exhibited?

• <some business value sought>– <some solution increment>• <some role>• <some product capability>• <some benefit to the role>

– <some solution increment>• <some role>• <some product capability>• <some benefit to the role>

User Stories

• Grouping of cohesive examples• Explains the role, capability and incentive

As <some role>I want <some capability>So that <some benefit to the role>

Example

PrintCo – a Printer Manufacturer

We need mandatory

registration on our website

• Why? Because we need more e-mail addresses• Why? Because we want to e-mail more

customers• Why? Because 3% of them buy consumables

and this will increase our consumable sales figures

So ,we will increase revenue by increasing our mailing list

• Role: PrintCo Customers• Behaviour: Give us their e-mail addresses• Incentive: Get special deals on consumables

Increase PrintCo Consumable Sales

As PrintCo CustomerI want to be asked for my e-mail address via the websiteSo that I can get monthly e-mails with special deals on consumables

As a PrintCo CustomerI want to be e-mailed with deals specific to my printerSo that I don’t have to wade through irrelevant info

Should capture valid email address:name[+comment]@somwhere.com

Should reject black-hole addresses: *@example.com
