    • Advantage & Disadvantage
  • Introduction
    • Need software management methods to decrease the cost
    • 28% completed on time and budget
    • 23% failed
    • 49% challenged
    • 72% not meeting original goals
  • Waterfall Life Cycle X
  • Agile Method
    • Continuous attention to technical excellence and good design
    • Self-organizing teams
    • Customer satisfaction by rapid, continuous delivery of useful software
    • Working software is the principal measure of progress
    • Delivered frequently
  • Agile Method (cont)
    • Late changes in requirements
    • Close, daily cooperation between business people and developers
    • Face-to-face conversation is the best form of communication
    • Time is a fixed variable
  • Agile Manifesto
    • “ We are uncovering better ways of developing software by doing it and helping others do it. Through this work we have come to value:
    • Individuals and interactions over processes and tools
    • Working software over comprehensive documentation
    • Customer collaboration over contract negotiation
    • Responding to change over following a plan
    • That is, while there is value in the items on the right, we value the items on the left more.”
  • Scrum
    • Rugby
    • Eight individual
    • Move the ball down the field
    • One Goal
  • Sprints
    • Scrum project make progress in a series of Sprints
    • Timeboxed Period (2 – 4 weeks)
    • During Sprint, team does:
      • Analysis
      • Design
      • Code
      • Test
    • Product is potentially releasable after every Sprint
  • Potentially Shippable Product Increment
    • At the end of each Sprint, the Team must produce a potentially shippable product increment (commit by the Team)
      • High Quality
      • Tested
      • Complete
      • Done
  • Product Owner
    • Represents (or is) the user or customer for the project
    • Knowing what to build and in what sequence
    • Defines goals for overall project
  • Product Backlog
    • The requirements
    • A dynamic list of all desired work on the project
    • Prioritized by the Product Owner
    • Reprioritized at the start of each Sprint
  • ScrumMaster
    • Responsible for enforcing the values and practices of the framework and the Team
    • Remove impediments
    • Educate outside groups about how the Teams is working
    • Improve productivity in any way possible
    • Facilitate Team meetings
    • Servant Leader
  • Daily Scrum Meeting
    • Tasks that is completed
    • Obstacles to complete specific task
    • Plan to accomplish between now and the next Scrum meeting
  • Scrum of Scrum
    • Synchronize inter-team work
      • Issue list is up-to-date
      • Discuss impediments
  • Sprint Planning
    • Happens on the 1 st day of the Sprint
    • Scrum Team takes the Sprint Goal and decides what Product Backlog are necessary
    • Team self-organizes around how they’ll meet the Sprint Goal
    • Sprint Backlog is created
  • Release Planning
    • Several Days before Sprint Planning
    • What will be built
    • Identify top level priorities
    • Select more than what the Team can likely do in one Sprint
  • Sprint Review
    • Updates to Product Owner
    • Plans for next Sprint
      • Change in Requirements
    • Demonstration
  • Risk Management
    • Risk is low
    • Continue testing
    • Problem is notified during Daily Scrum Meeting
  • System Representation Release Planning Sprint Planning Ideas Programming Daily Scrum Sprint Review Release Review Working Code Error Error Product Backlog Release Backlog Sprint Backlog
  • Advantage & Disadvantage + Continuous testing and communication can find issues rapidly - Might not find bugs until later stage Risk Management - Knowledge is stored mentally - Code is the documentation + Highly emphasize + Requires in every stage Documentation + Good internal communication + Higher quality - Lack of communication with the customer and team members Communication + Micro Planning + Avoid Requirement cramming - Might be headed toward wrong direction + Able to see the overall project Planning + No delays on important features + Less important features might scaled back or dropped + Support for long-term plans Prioritization Agile Method Traditional Management
