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>

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
