Effective requirements are crucial for successful software development, as they define the vision, goals, and user journeys. Responsibility for good requirements is a collective effort involving all stakeholders, not just the writers. Key strategies for crafting effective requirements include understanding the audience, maintaining focus, and exercising common sense.

Determine your succesGreat requirements always lead to success while poor requirements ultimately
lead to failure and confusion. Requirements that are “meh” can take last place for
not having even tried.

4. Who gets the blame?
When a product misses the mark?
The people who wrote the requirements!

5. Why?Because requirements have the ability to;
• Define the vision
• Enunciate the goals and objectives of the system.
• Outline the users and audience of the application.
• Account for all dependencies and interactions
In essence – they weave the story as to how a user
traverses your application.

6. It must be the fault

So where
do you
start?

13. #1 - Know your audience
Stakeholders don’t care about Product Backlog Items.
They care about the story and the translation of their
requests into an application.
Know who you are writing for!

14. #2 - Tell a Story
Don’t get sucked into metholodiges – what
worked for one person might not work for
you.
When you start writing a requirement a
certain way “just becase”, you’ve already
lost your way.

15. • What must exist in your world for
your requirements to work?
• Define the Pre and Post Conditions

#3 - Outline Dependencies

16. #4 - SAndbox
What world does your
requirement operate in?
Keep it there, don’t jump all over
the place, stay focused.

17. #5 - Scenario AnalysisRun through the happy and edge paths, define them, why do they exist,
who do they serve, is it for your audience?

18. #6 - Common Sense
If it doesn’t fit,
if it seems out of place,
don’t put it in there.
If you need more information,
add it in!

20. BE AWAREDon’t get pulled into writing a requirement in a specific way
because the methodology “du jour” says you have to OR ELSE!
