Applying Agile Methodology

- Harmeet Sudan, PMP

Waterfall vs. AgileThe Waterfall approach to product development may conflict with the goals of maximum speed and flexibility. Instead a holistic or “rugby” approach – where a team tries to go the distance as a unit, passing the ball back and forth – may better serve today’s competitive requirements.

The Agile Manifest – a Statement of Values

Process and toolsIndividuals and interactions over

Following a planResponding to change over

Comprehensive documentationWorking software over

Contract negotiationCustomer collaboration over

Rather than doing all of one thing at a time...

...Scrum teams do a little of everything all the time

Requirements Design Code Test

Sequential vs. overlapping development

Scrum is an agile process 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 in 100 words

Self-organizing teams Product progresses in a series of month-long

“sprints” Requirements are captured as items in a list of

“product backlog” No specific engineering practices prescribed Uses generative rules to create an agile

environment for delivering projects One of the “agile processes”

The Planning Onion

Agile teams plan on the innermost three levels.

Others (on the team in the company) plan on the outer three levels.

“Yesterday I started on the UI; I should finish before the end of today.”

Scrum projects make progress in a series of “sprints”◦ Analogous to Extreme Programming iterations

Typical duration is 2-4 weeks or a calendar month at most

A constant duration leads to a better rhythm Product is designed, coded, and tested during

the sprint

Sprints

• Plan sprint durations around how long you can commit to keeping change out of the sprint

Team Typically 5-9 peopleCross-functional:

Programmers, testers, user experience designers, etc.Members should be full-time

May be exceptions (e.g., database administratorTeams are self-organizing

Ideally, no titles but rarely a possibilityMembership should change only between sprints

Scrum Roles


Roles

Artifacts


Ceremonies

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 ScrumMaster

High-level design is considered

Sprint Planning

As a vacation planner, I want to see photos of the hotels.

Code the middle tier (8 hours)Code the user interface (4)Write test fixtures (4)Code the foo class (6)Update performance tests (4)

Parameters◦ Daily◦ 15-minutes◦ Stand-up

Not for problem solving◦ Whole world is invited◦ Only team members, ScrumMaster, product owner,

can talk Helps avoid other unnecessary meetings

The Daily Scrum

These are not status updates for the ScrumMaster◦ These are commitments in front of peers

Everyone Has Three Questions

What did you do yesterday?1

What will you do today?2

Is anything in your way?3

Team presents what it accomplished during the sprint

Typically takes the form of a demo of new features or underlying architecture

Informal◦ 2-hour prep time rule◦ No slides

Whole team participates Invite the world

The Sprint Review

Periodically take a look at what is and is not working

Typically 15-30 minutes Done after every sprint Whole team participates

◦ ScrumMaster◦ Product owner◦ Team◦ Possibly customers and others

Sprint retrospective

Start / Stop / Continue• Whole team gathers and discusses what they’d like

to:

Start doing

Stop doing

Continue doingThis is just one of many ways to do a sprint retrospective.

Product backlog

•The requirements

•A list of all desired work on the project

•Ideally expressed such that each item has value to the users or customers of the product

•Prioritized by the product owner

•Reprioritized at the start of each sprintThis is the

product backlog

A Sample Product BacklogBacklog item Estimate

Allow a guest to make a reservation 3As a guest, I want to cancel a reservation. 5As a guest, I want to change the dates of a reservation. 3As a hotel employee, I can run RevPAR reports (revenue-per-available-room) 8Improve exception handling 8... 30... 50

The sprint goal• A short statement of what the work will be focused

on during the sprint

Database Application

Financial services

Life SciencesSupport features necessaryfor population genetics studies.

Support more technical indicators than company ABC with real-time, streaming data.

Make the application run on SQL Server in addition to Oracle.

Individuals sign up for work of their own choosing◦ Work is never assigned

Estimated work remaining is updated daily Any team member can add, delete or change the

sprint backlog Work for the sprint emerges If work is unclear, define a sprint backlog item with a

larger amount of time and break it down later Update work remaining as more becomes known
