4. The Agile Manifesto
We are uncovering better ways of developing software
by doing it and helping others do it.
Through this work we have come to value:
Individuals & Interactions over processes & tools
Working software over comprehensive
documentation
Customer collaboration over contract negotiation
Responding to change over following a plan
That is , while there is value in the items on the right,
we value the items on the left more.

8. Product Owner:
✤ Responsible for: Creation and
maintenance of a stack ranked
product backlog.
✤ Gathering of customer, business,
and technical requirements and
filtering them down to a single
product backlog.
✤ Full understanding of the product
and the process.
✤ Maintaining upward visibility.
✤ Representation of customer and or
sponsor to the end team

9. Agile Analysts:
✤ There are 3 types of analysts to assist the product owner in creation
and maintenance of the product backlog:
✤ 1) Technical Analyst - This analyst understands the way that the
current product is built and can assist in determining technological
feasibility of future enhancements.
✤ 2) Functional Analyst - This analyst knows exactly how the current
product works and understands the direction in which the business
hopes to take the future of the product. This analyst is also typically
very savvy about how end users typically use the product.
✤ 3) Business Analyst - This analyst has a deep understanding of the
customers wants, needs, and desires. They often negotiate with the
business to get features into the product that the customer will
actually use.

✤ The ScrumMaster can be a great

management.

11. The 3 C’s of a Good User Story:
✤ 1) The Card - The topic of the backlog item, the high level
description of the desired system behavior.
✤ 2) The Conversation - Detailed requirements are only
discovered after the backlog item has been pulled into a sprint.
This is a dialog between the product owner and the
development team.
✤ 3) The Confirmation - Criteria that insures the backlog item
was completed to the specifications of the product owner. The
customer will evaluate the competed backlog item against the
acceptance criteria, and if all tests pass, approve the backlog
item by the end of the sprint.

14. INVEST - Attributes of a Good Backlog
Item
Independent Estimable
Avoid dependencies with other stories Enough detail should be listed to allow the team to estimate
Write stories to establish foundation The team will encounter problems estimating if the story is too
big, if insufficient information is provided, or if there is a lack of
Combine stories if possible to deliver in a single iteration domain knowledge
Negotiable Sized Appropriately
Stories are not a contract Each story should be small enough to be completed in a single
iteration
Too much detail up front gives the impression that more
discussion on the story is not necessary Small detailed stories for the near future
Not every story must be negotiable, constraints may exist that Larger stories are okay if planned further out (Epics)
prevent it
Valuable Testable
Each story should show value to the Users, Customers, and Acceptance criteria stated in customer terms
Stakeholders
Automate whenever possible
All team members should demand clear acceptance criteria

15. Understanding Roles:
✤ Different types of end users
may interact with the system
differently.
✤ Each role may have many
different personas that will
exhibit different behaviors
and use the same system in
a very different way.
✤ Roles help us define broad
stroke acceptance criteria
that should be applied
globally within a system.

16. Understanding Personas
✤ Defining who more specifically
will benefit from what you are
building helps drive added value.
✤ This helps teams focus on the
20% of the features that are used
most of the time.
✤ Using personas also helps the
team consume backlog items
with much lighter documentation
✤ Most organizations create a
handful of most commonly used
personas to assist the team in
building the product.

18. What About Business Priority?
✤ We all know the business has a
3 point ranking scale for priority
of backlog items: High, Really
High, or Really Really High.
✤ The business needs to use tools
to help them understand that
not everything can be of the
highest priority.
✤ With the understanding that we

we arrange them into High,
Medium, and Low categories?

20. Time vs. Relative Complexity
✤ Let’s paint the room!
✤ How many hours will it take?
✤ Why all of the different answers?
✤ Have any of you painted before?
✤ Compared to something else
you have painted, would it be
easier to determine how difficult
it would be to paint the room?
✤ Is it easier to reach consensus?

24. Understanding MoSCoW:
✤ MoSCoW = more than a Russian Capital
✤ Must Have
✤ Should Have
✤ Could Have
✤ Would Like
✤ Every iteration should have a mix of
the above types of items.
✤ Stake holders LOVE the Would Likes.
✤ The Product Owner drives the product
backlog and creates the rank order
based heavily on the MoSCoW ratings.

26. The Formula
✤ Here is the formula for correct placement of stack
rank order of your backlog items. Address risk by
performing the items with the highest complexity Must Have High Priority
earlier working towards the lower complexity items
later in the process:
Would Like H-M-L
✤ 1) All Must Have High Priority items should be
considered first and foremost. Must Have Medium
Priority
✤ 2) Be certain to get at least one Would Like in every
sprint. Next should be one Would Like High Priority Must Have Low Priority
item.
✤ 3) Next should be the Must Have Mediums and Must
Should Have H-M-L
Have Lows.
Could Have H-M-L
✤ 4) The Should’s go next from High to Low Priority.
✤ 5) Finally, place the Could’s from Highest to Lowest All states are stack ranked from highest
Priority. to lowest risk unless the velocity of the
Sprint does not afford this as an option.
Team velocity always prevails.
✤ Note: Dependencies trump priority & moscow rating.
