• Scrum Framework: Ceremonies
• Scrum Framework: Artifacts
• Clarion Scrum Process-Review
Traditional Methodologies: Waterfall Model
• You complete one phase (e.g. design) before moving on to the next phase(e.g. development)
• You rarely aim to re-visit a ‘phase’ once it’s completed. That means, you better get whatever you’re doing right the first time!
Traditional Methodologies: Waterfall Model
• You don’t realize any value until the end of the project
• You leave the testing until the end
• You don’t seek approval from the stakeholders until late in the day
• Takes too long…
**This approach is highly risky, often more costly and generally less efficient than Agile approaches

Responding to change
OVER
12 Agile Principles
• Our highest priority is to satisfy the customer through early and continuous delivery of valuable software.
1 ROI
12 Agile Principles
• Welcome changing requirements, even late in development. Agile processes harness change for the customer's competitive advantage.
2 CHANGEABILITY
12 Agile Principles
• Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale.
3 GETTING REAL
12 Agile Principles
• Business people and developers must work together daily throughout the project.
4 ALIGNMENT
12 Agile Principles
• Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done.
5 SELF ORGANIZATION
12 Agile Principles
• The most efficient and effective method of conveying information to and within a development team is face-to-face conversation.
6 BANDWIDTH
12 Agile Principles
• Working software is the primary measure of progress.
7 DONE
12 Agile Principles
• Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely.
8 SUSTAINABILITY
12 Agile Principles
• Continuous attention to technical excellence and good design enhances agility.
9 IMPROVEMENT
12 Agile Principles
• Simplicity —the art of maximizing the amount of work not done —is essential.
10 KEEP IT SIMPLE, STUPID (KISS)
12 Agile Principles
• The best architectures, requirements, and designs emerge from self-organizing teams.
11 EMERGE
12 Agile Principles
• At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly.
12 INSPECT & ADOPT
Various Agile Methodologies
Meaning Of Scrum (Literally)
What Is Scrum?
• Scrum is an agile framework that allows us to focus on delivering the highest business value in the shortest time.
• It allows us to rapidly and repeatedly inspect actual working software (every two weeks to one month).
• The business sets the priorities. Teams self-organize to determine the best way to deliver the highest priority features.
• Every two weeks to a month anyone can see real working software and decide to release it as is or continue to enhance it for another sprint.
Scrum Origins
Controversies
Some professionals believe that Jeff Sutherland, John
Scumniotales and Jeff McKenna invented Scrum
in 1993.
Others, who vouch for HirotakaTakeuchi and
IkujiroNonakaas inventing Scrum in 1986.

• Ensure that the team is fully functional and productive
• Enable close cooperation across all roles and functions
• Shield the team from external interferences
Role: The Team
• Typically 5-9 people
• Cross-functional• Programmers, testers, user experience designers, etc.
• Members should be full-time• May be exceptions (e.g., database administrator)
• Teams are self-organizing• Ideally, no titles but rarely a possibility
• Membership should change only between sprints.
Clarion Role Mapping
Product owner/Shadow product owner
Scrum master
Cross functional scrum team
Product owner is generally from client side and shadow product owner would be from BA/SA offshore side. In some cases product owner could be from offshore, who has gained detailed product/system knowledge, this scenario does not require Shadow PO.
Team facilitator from offshore side to drive overall scrum process
Technical Architect (onsite + offshore), Technical Leader, QA, Developers and Designers.

Artifacts
Ceremony: Sprint Planning Meeting
• Team selects items from the product backlog they can commit to completing
• Sprint backlog is created• Tasks are identified and each is estimated (1-16 hours)
• Collaboratively, not done alone by the Scrum Master
• High-level design is considered
Clarion: Sprint Planning Meeting
• Purpose: At every sprint start, sprint backlog is created out of product backlog.
• Participants: Product owner, scrum master, team
• Duration: This is a time-boxed meeting, duration depends on the duration of sprint and complexity of the items.
• Highlights:• Fibonacci point based estimates which would be related to the complexity / time of
the tasks.
• Stories are discussed in sprint planning meeting and estimation will be given by developers on based of story, planning poker is used for the user story estimation.
• Generally for 1 point we consider 2-3 hours work, 2 pointer it is a half day work, 3 pointer is a days work and 5 pointer is 2 days work.
Planning Poker
• Product Owner reads story
• Team estimates (including QA/Testing)
• Team Discusses
• Team estimates again
This process is repeated till consensus is reached.

User Story
A concise, written description of a piece of functionality that will be valuable to a user (or owner) of the software.
A user story should be detailed enough for the team to start work from, and further details can be established and clarified at the time of development.
3C’s Of User Story
• Card - A written description of the user story for planning purposes and as a reminder.
• Conversation - A section for capturing further information about the user story and details of any conversations.
• Confirmation - A section to convey what tests will be carried out to confirm the user story is complete and working as expected.
User Story: Invest In It
• Independent - User Stories should be as independent as possible.
• Negotiable - User Stories are not a contract. They are not detailed specifications. They are reminders of features for the team to discuss and collaborate to clarify the details near the time of development.
• Valuable - User Stories should be valuable to the user (or owner) of the solution. They should be written in user language. They should be features, not tasks.
• Estimable - User Stories need to be possible to estimate. They need to provide enough information to estimate, without being too detailed.
• Small - User Stories should be small. Not too small. But not too big.
• Testable - User Stories need to be worded in a way that is testable, i.e. not too subjective and to provide clear details of how the User Story will be tested.
User Story: Format
As a [role] I want to [a feature] so that [reason, value].
As a frequent traveler I want to be able to quickly rebook frequently booked flights so that I can save time during the booking process.
User Story: Example
• Epic#1: User Authentication and Authorization Module
• Story#1: Registration System for school user
• Description: As a visitor of the site, I want to be able to register by providing my email and password in order to use the available features.
• Acceptance Criteria:• I should be presented with a link on top right corner to register titled ‘Register’.
• I should be presented with a form asking email, password, password confirmation.
• I should be presented with a Register button, clicking on which I should be registered as a user on app.
• I should be presented with errors in case of incorrect email format and a password shorter than 8 chars.
Artifact: Sprint Backlog
• The sprint backlog is a list of tasks identified by the Scrum team to be completed during the Scrum “Sprint”.
• During the sprint planning meeting, the team selects some number of product backlog items
What Is Sprint?
A sprint is a set period of time during which specific work has to be completed and made ready for review.
More precisely we can say a Sprint is a Time Box.
• During the actual sprint, team implements the user stories committed to the sprint backlog in continuous integration mode.
• Duration: Usually from 2 weeks to 4 weeks.

Every sprint consists of iteration of following tasks
Actual Sprint - Starting Mid-week
• Advantages & probable scenarios when this cycle would be suggested• This way even if we have to stretch a bit to finish some tasks, team would not
hesitate to do it during mid-week.
• In addition to this if teams are working in distributed agile set-up, then mid-week start helps the product owner to be easily available.
• This cycle is suitable when the releases can be done on weekdays.

Sprint Zero High Level Tasks• Initial grooming of the product catalog.• Decide maximum base point for user story.• Decide the sprint duration and sprint release cycle.• Technical understanding by team.• How and where QA would be done.• Setting up environments.
Artifact: Burn-down Chart
• Tells us about:• How much work is remaining to be
done in the project
• How much deviation we are having from the current estimation or are we pulling in lot of tasks in the sprint

Add On’s: Velocity Chart
• Shows the amount of value delivered in each sprint, enabling you to predict the amount of work the team can get done in future sprints.
• It is useful during your sprint planning meetings, to help you decide how much work you can feasibly commit to.
• Initial velocity figures could below, however a steam moves forward we get the better idea about the capability of the team.
