WHAT IS THIS ?


I HAVE A DREAM
• My project
o In Time

o Within Budget

o Meet Requirements

• Members in my team
o Creative & responsive

o Not exhausted and not leave team


Project Management Triangle

SCOPE COST

TIME

Typical developer
• Personal interest is more than team interest
• Warm up time is long
• Good at patching but bad at designing
(problem solving style)
• Wait for thing happens but not make thing
happen


Waterfall

Analysis Design Develop Test Deploy


Parkinson’s Law
“Work expands so as to
fill the time available for its completion”


Don’t assign one week task,
Break it into smaller sub tasks !

Gantt chart gets bigger & bigger.
No one can read Gantt chart


Waterfall is easy to understand
but it is not effective in real


WHAT SCRUM CAN HELP?


Agile
“Methodologies”


Scrum is an Agile framework
Scrum is an iterative, incremental
framework for project management and

Principles of Agile #1
• Deliver valuable software early &
continuously
• Accommodate changes
• Collaborate with customer or customer
proxy
• Motivate individuals  Self-organizing
teams  Self tuning


Principles of Agile #2
• Enforce effective & transparent
communication
• Measure of progress by working
software delivered. Highlight amount of
work not done
• Maintain a development speed
• Promote technical excellent and good
design

DIFFERENCES
Plan Driven Scrum
• Hierarchy team • Self organizing team
• Lot of document • Deliver features
• Follow plan • Response to change
• Structure • Flexible
• Gantt Chart • Burn down chart


Roles in Scrum

Scrum Master Scrum Team
Product Owner

Stakeholders &
Users


Product Owner
• Define the features of the product
• Decide on release date and content
• Be responsible for the profitability of the
product (ROI)
• Prioritize features according to market value
• Adjust features and priority every iteration, as
needed
• Accept or reject work results


The Scrum Master
• Manage project

• Enforce Scrum values and practices

• Help team to focus on tasks

• Enable close cooperation across all roles and
functions

• Shield the team from external interferences


The team

• Typically 5-9 people
• Cross-functional:
– Programmers, testers, user experience designers, etc.

• Teams are self-organizing
– Ideally, no titles but rarely a possibility

• Membership should change only between sprints

Meetings in SCRUM
Meeting Purpose Duration Frequency
Sprint Determine what work to do in 2 hours per Once per
Planning the coming sprint. week sprint
Daily Allow team members to 15 minutes Daily
Scrum commit, collaborate, and
communicate risks.
Sprint Show the customer and other 2 hours per Once per
Review stakeholders the work that the week sprint
team accomplished in the
sprint, and receive feedback.

Daily Scrum
• Daily, 15 minutes, whole team
• What did you do yesterday ?
• What will you do today ?
• What are impediments?

No need minutes meeting
Need a tool to keep track

“Music Store” web site
• Team : 1 PM - 1 dev – 1 ux designer
• Mission: Develop “Music Store” site in 3
months.
• Every 2 weeks must show customer progress
• Team work 5 days a week, 8 hours per day
(Utilize rate 75% ~ 6 hours per day)


Example Solution
• Each Sprint takes 2 weeks
• 4 months  8 Sprints
• Each sprint, a person burns 5*2*6=60 hours.
A team burns 60*3=180 hours

Idle hours will not be counted

Hours which used to complete task
will be counted as burnt hours

Workspaces: local working copy

Map Server to Per User, Per
Local Workstation

Changes in
Also Used for
Workspace create
Builds
“Pending Changes”


Changesets
• Logical container of data related to check-in
– File and branch information

– Links to work items

– Check-in notes

– Check in Policy

– Metadata (date-time, user)

– Atomic checkin

• Uniquely identified
• Trace & query easilly


Other terms of TFS version control
• Integrated Check-in
• Check-in policies
• Shelve
• Label
• Branch / Merge
More at
http://www.slideshare.net/stevenl/team-
foundation-server-2010-version-control


Check-in Policies
• Soft requirements for check-in

• Extensible

• Can be overridden


Client Server vs Distributed SCM

• Clients push-pull master Exchanging patches
repository. (change-sets) from
peer to peer
• A client hold only a working
copy of a project tree
• Changes by client commits the
master repository before they
propagate to other users

Client Server vs. Distributed
• TFS, CVS, SVN, Perforce, Vault are client-
server SCM
• Git, Mercurial are distributed SCM
• Distributed SCM:
o No canonical, reference copy of the codebase
exists by default; only working copies
o Basic operations (c-in, c-out) are fast
o Each working copy acts as remote backup
o Suitable for Open Source development but not
commercial development

CI in TFS 2010


Team Foundation Build
• Manual: run by team member
• Continous: queued by a check-in
• Rolling: accumulated until previous build
finishes
• Gated check in: Check-in is accepted only if
submitted changes merge and build
successfully
• Scheduled: run on a defined schedule

ROI ANALYSIS OF SUCCESSFUL
SCRUM & TFS DEPLOYMENT


ROI Analysis for dev team

More productive 120-150%

Fix bug earlier. Fixing cost 70-90%

Amount of captured know-how 200-300%


ROI Analysis for customer
Receive workable software regularly

Control investment better

Get better quality software
