12 Principles

• Our highest priority is to satisfy the customer through early and continuous delivery of valuable software.

• Welcome changing requirements, even late in development. Agile processes control change for the customer’s competitive advantage.

• Delivery working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale.

12 Principles• Business people and developers must work together daily

throughout the project.

• Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done.

• The most efficient and effective method of conveying information to and within a development team is face-to-faceconversation.


12 Principles

• Working software is the primary measure of progress.

• Agile processes promote sustainable development, The sponsors, developers, and users should be able to maintain aconstant pace indefinitely.

• Continuous attention to technical excellence and good designenhances agility (speed)


12 Principles

• Simplicity -- the art of maximizing the amount of work not done is essential.

• The best architectures, requirements, and designs emerge fromself-organizing teams.

• At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly.


Agile Business Analysis• Iterative

• Streamlined

• Time-Boxed

• Collaboration

• Releases come early and often

• Communication about the impact of changes

• How to manage the Budget

Lean• A systematic method for waste minimization from Toyota

• A set of tools that assist in the identification and steady elimination of waste. As waste is eliminated, quality improves while production time and cost are reduced

• Types of waste• Transport :• Inventory :• Motion :• Waiting :• Over Production :• Over Processing :• Defects :

Scrum Theory

• Empirical Process• Iterative

• Incremental

• Time-boxed

• Collaboration

• 3 Principles• Transparency (task is really meet the definition of done) : open &

honest as a team

• Inspection (check on progress of the sprint goal): 2 weeks

• Adaptation (change the product based on inspection)

Scrum Artifacts• Product Backlog: An that is known

to be (The product owner is responsible)

• Sprint Backlog: selected and delivering the product increment that realizing the

Sprint Goal.

• Product Increment: The completed during a Sprint and the value of the increments of all previous Sprints. At the end of a Sprint, the new increment must be “Done”

30http://www.scrumguides.org/scrum-guide.html

Scrum Events (Time-boxes)• The Sprint (The heart of scrum):

• Sprint Planning: 4 hours meeting for 2 weeks with 2 topics, “ ” and “ ”, then break the story to tasks to commit

• Daily Scrum: Coordination within

• Sprint Review: Make sure that with the team feeding back to the next sprint

• Sprint Retrospective: Meeting to

3 Questions for daily scrum

• What will to help the development team?

• Do I see any me or development team from meeting the Sprint Goal?

Retrospectives

34

3 Questions for Retrospective

• What went well during this Sprint?

• What did not go so well during this Sprint?

• What can we do better next time?

35

Burndown Chart• The progress of the team

is tracked using a burndown chart, one of the best project visibility tools, and visual represents a

• The burndown chart provides a

that remains in a given sprint or release.

885

Burndown Velocity• The slope of the graph, or

, is calculated by comparing the number of hours worked to the original project estimation and shows the average rate of productivity for each day


885

410

Example• You have to finish the Sprint

01 in 885 hours of work within 30 days

• The ideal burndown velocity is / = h/day

• The minimum team member who works 8 h/day is / 8 = 3.7 4 person


885

410

Example• After day 19 the work remains

410 hours

• The finished work is 885 - 410 = hours, then the current rate of productivity is / 19

= h/day

• If you want to finish on time in the next 10 days, you have to work / 10 = h/day

• With the current rate you will finish the work in / 25 = 16.4 17 days
