Goldfinger is blown out of the cabin.

We want to show on statements the reductions that weren't applied

Refuse solutions to unknown problems: understand what the real problem is and solve that

We found this IP geolocation service – let's use it to identify where the customers are from

Refuse suggestions to use a technology: you know IT better than they do (if not, why have they hired you?)

“ We want to give our affiliates real-time reports”

Don't rush into solving the first problem they give you: keep asking “why” until you get to the money

We have performance issues with the counterparty hierarchy – fix it!

Know your stakeholders: who is going to use this and why?

We want to send video to mobile devices

Don't start with stories!
Start with a very high level example of how people will use the system

We want a 2.5 Mach fighter jet

Great products come from understanding the real problem and whose problem it is

Effect maps
Why? What is the desired business change?
Who are the people that can create desired effects?
What does the target group want, need, should do?
How should the product or operation be designed to fulfil that?

Remember
Share the responsibility for requirements
Requirements shouldn't be taken at face value
Refuse requirements in form of tasks
Know your stakeholders
Make a clear map from tasks to goals
Start with high level examples
Derive features and stories from that
Communicate intent
Focus on what , not on how
