Overview of Agile and Scrum

Agile Principles …cont’d

• Continuous attention to technical excellence and good design enhances agility

• Simplicity (art of maximizing amount of work not done) is essential

Overview of Agile and Scrum

What is Scrum

• Scrum is an Agile framework that supports lightweight processes that emphasize:

▫ Incremental deliveries

▫ Quality of Product

▫ Continuous improvement

▫ Discovery of people’s potential

• Scrum is simple to understand, but requires discipline in order to be successful

• Scrum is not a methodology

8

Overview of Agile and Scrum

Foundations of Scrum• Empiricism

▫ Detailed up-front planning and defined processes are replaced by just-in-time Inspect and Adapt cycles

• Self-Organization▫ Small teams manage their own workload and organize themselves

around clear goals and constraints

• Prioritization▫ Do the next right thing

• Rhythm▫ Allows teams to avoid daily noise and focus on delivery

• Collaboration▫ Leaders and customers work with the Team, rather than directing

them

9

Overview of Agile and Scrum

Core Values

• Transparency

▫ Everything about a project is visible to everyone

• Commitment

▫ Be willing to commit to a goal

• Courage

▫ Have the courage to commit, to act, to be open and to expect respect

• Focus

▫ Focus all of your efforts and skills on doing the work that you have committed to doing

• Respect

▫ Respect and trust the different people who comprise a team

Vision and Product

Please dial in to +1 (775) 996-3560 PIN: 699601#

The Product Vision----Why?

• The Vision serves as a common bonding to the Project, every participant needs to understand and share it, to be able to contribute effectively

13

The Vision Board

- Visible to the team

- Maintained by the Product Owner/ Customer

14

Role: Product Owner

• Thought Leader and Visionary

• Steers the Product Vision (for example, with Story Mapping)

• Prioritizes the Goals - User Stories

• Maintains the Product Backlog with the team

• Accepts the Working Product (on behalf of the customer)

15

Agile planning

Please dial in to +1 (775) 996-3560 PIN: 699601#

Why Plan?

• Gives the Product Owner & Customer Opportunity to explain the vision, goals and requirements.

• Helps in fulfillment of customer specification.

• Communicate the bigger picture to team members

• Keep team's focus on what can be achieved

17

Why We Need Plans?

• To predict the future

• To communicate our expectation

• To be able to compare our predictions with the reality we are facing

• To guide us to the desired situation/state

18

What is a good plan?

► A good plan is one that supports reliable decision-making

► One that increases in accuracy and precision over time

We’ll be done in the fourth quarter

We’ll be done in November

We’ll be done November 7th

19

“It is better to be roughly right than precisely wrong.”

-John Maynard Keynes

What makes planning “Agile”?

•Focus on planning – not the plan

•Re plan based on reality

•Involve people who are doing the work in planning

•Balance benefit and investment

•Adaptive to change and learning

•Plans are easily changed

•Planning is continuous throughout the project

20

Different levels of planning

21

Agile Planning Lifecycle Summary

22

The Goals Of Release Planning

• A time question: How many iterations approximately will we need to deliver this rough scope having the resources we might have?

• Scope question: How much of this rough product backlog can we do within this range of sprints and having the resources we might have?

• Resources question: What resources do we need to accomplish this rough scope within this range of sprints?

• How rough can this be? What level of accuracy do we need?

• What things do we need to know to make each of these predictions?

23

The Goals Of Iteration Planning

• Duration is fixed.

• Resources are fixed and dedicated.

• Scope is open for discussions: how many backlog items (stories) can we do during the sprint?

• What level of accuracy do we need here?

• What we need to know to make the prediction?

24

The Goals Of Daily Planning

• Why we need this planning?

• How formal should this level of planning be?

• Who participated in Daily planning?

• Should you do it more often?

• Why is this usually out of scope in project running by a predictive process (e.g. waterfall)?

25

Release planning

Please dial in to +1 (775) 996-3560 PIN: 699601#

Release Planning

• How many iterations?

• How much scope?

• At what costs?

27

Estimating Backlog

• Backlog items expressed as User Stories

• Team estimates the Product Backlog

• Estimated in relative size

• Estimated 1 or 2 days before start of your iteration

• Discussing during the estimation more important that the estimates

• Planning Poker

28

Estimate Size – Derive Duration

30

Velocity

• A rate at which the team is able to convert product backlog items into working product.

• Measured for each iteration

• Expressed in relative size

▫ Story points

▫ Number of Stories

• Used as a reference by teams when committing for the next Iteration

31

• Shows progress across Sprints

• X-axis is the number of Sprints

• Y-axis is the total number of stories

32

Iteration planning

Please dial in to +1 (775) 996-3560 PIN: 699601#

• System requirements formulated as one or more sentences in the everyday or business language of the user

▫ As a <user>, I would like <function> so that I get <value>

• Each User Story has an associated Acceptance Criteria that is used to determine if the Story is completed

Iteration planning

Spirit behind User Stories

34

• Independent

▫ Not overlap in concept and be able to schedule and implement them in any order

• Negotiable

▫ Not an explicit contract for features; rather, details will be co-created by Product Owner and Team

• Valuable

▫ Add business value

• Estimated

▫ Just enough to help the Product Owner rank and schedule the story's implementation

• Sized Appropriately

▫ Need to be small, such as a few person-days

• Testable

▫ A characteristic of good requirements

Iteration planning

A Good User Story …

35

Iteration Planning

• Select the top PB items for the iteration▫ PO’s involvement is key and mandatory

• Team builds the task list for completing the stories

• Output in an Iteration Plan or Sprint Backlog

• Team makes a commitment at end of the planning session

36

Daily planning

Please dial in to +1 (775) 996-3560 PIN: 699601#

Daily planning: Daily Standup

• Meetings held in same location, same time, every day

• Time boxed at 15 minutes• Helps the “team” to plan everyday • Each Team member speaks to:

▫ What did I accomplish in the last 24 hours▫ What do I plan to accomplish in the next 24 hours▫ Any impediments getting in the way of my work

38

Daily Planning: Taskboard

• Active visual indicator of flow of work

• Should be visible to team members at all times

• Kept current by the team

• Reflection of Iteration commitment vrs reality

39

• Shows daily progress in the Sprint

• X-axis is the number of days in the Sprint

• Y-axis is the number of remaining stories

Daily planning : Burndown
