Transcript of Agile Scrum Methodology

  • An Introduction toAgile SCRUM Methodology

  • PresumptionsThe audience is well aware of traditional software development methodologies like Waterfall Model, Iterative models, etc.

  • AgendaIntroductionWhat is Agile Methodology?What is Scrum?History of ScrumFunctionality of ScrumComponents of ScrumScrum RolesThe ProcessScrum ArtifactsScaling ScrumQ & A Session

  • Introduction

    Classical methods of software development have many disadvantages: huge effort during the planning phase poor requirements conversion in a rapid changing environment treatment of staff as a factor of production

    New methods:

    Agile Software Development Methodology

  • What is Agile ?Agile proponents believeCurrent software development processes are too heavyweight or cumbersomeToo many things are done that are not directly related to software product being producedCurrent software development is too rigidDifficulty with incomplete or changing requirementsShort development cycles (Internet applications)More active customer involvement neededCMM focuses on process

  • ContdAgile methods are considered LightweightPeople-based rather than Plan-basedSeveral agile methodsNo single agile methodXP most popularNo single definitionAgile Manifesto closest to a definitionSet of principlesDeveloped by Agile Alliance

  • Agile Manifesto A Statement of ValuesIndividuals and interactions over processes and toolsWorking software over comprehensive documentationCustomer collaboration over contract negotiationResponding to change over following a plan http://www.agilemanifesto.org

  • Agile MethodsAgile methods:ScrumExtreme ProgrammingAdaptive Software Development (ASD)Dynamic System Development Method (DSDM)Agile Alliance (www.agilealliance.org)A non-profit organization promotes agile development

  • Scrum

  • Scrum in 100 wordsScrum 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. Our teams self-manage 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 for another iteration.

  • History of Scrum1995: analysis of common software development processes not suitable for empirical, unpredictable and non-repeatable processes Design of a new method: Scrum by Jeff Sutherland & Ken SchwaberEnhancement of Scrum by Mike Beedle & combination of Scrum with Extreme Programming

    1996:

    introduction of Scrum at OOPSLA conference

    2001:

    publication Agile Software Development with Scrum byKen Schwaber & Mike Beedle

    Successful appliance of Scrum in over 50 companiesFounders are members in the Agile Alliance

  • CharacteristicsSelf-organizing teamsProduct progresses in a series of month-long sprintsRequirements are captured as items in a list of product backlogNo specific engineering practices prescribedUses generative rules to create an agile environment for delivering projectsOne of the agile processes

  • How Scrum Works?

  • SprintsScrum projects make progress in a series of sprintsAnalogous to XP iterationsTarget duration is one month+/- a week or twoBut, a constant duration leads to a better rhythmProduct is designed, coded, and tested during the sprint

  • Sequential vs. Overlapping Dev.

    RequirementsDesignCodeTest

  • No changes during the sprintPlan sprint durations around how long you can commit to keeping change out of the sprint

  • Scrum FrameworkRoles : Product Owner, ScrumMaster, Team Ceremonies : Sprint Planning, Sprint Review, Sprint Retrospective, & Daily Scrum Meeting Artifacts : Product Backlog, Sprint Backlog, and Burndown Chart

  • Product OwnerDefine the features of the productDecide on release date and contentBeresponsible for the profitability of the product (ROI)Prioritize features according to market value Adjustfeatures and priority every iteration, as needed Accept or reject work results.

  • The Scrum MasterRepresents management to the projectResponsible for enacting Scrum values and practicesRemoves impediments Ensure that the team is fully functional and productiveEnable close cooperation across all roles and functionsShield the team from external interferences

  • Scrum TeamTypically 5-10 peopleCross-functionalQA, Programmers, UI Designers, etc.Members should be full-timeMay be exceptions (e.g., System Admin, etc.)Teams are self-organizingWhat to do if a team self-organizes someone off the team??Ideally, no titles but rarely a possibilityMembership can change only between sprints

  • CeremoniesSprint Planning MeetingSprintDaily ScrumSprint Review Meeting

  • Spring Planning Meeting

    Sprint PlanningMeetingSprint BacklogProduct OwnerScrum TeamManagementCustomersSprint Goal

  • Parts of Sprint Planning Meeting1st Part:Creating Product Backlog Determining the Sprint Goal. Participants: Product Owner, Scrum Master, Scrum Team2nd Part:Participants: Scrum Master, Scrum TeamCreating Sprint Backlog

  • Pre-Project/Kickoff MeetingA special form of Sprint Planning MeetingMeeting before the begin of the Project

  • SprintA month-long iteration, during which is incremented a product functionalityNO outside influence can interfere with the Scrum team during the SprintEach Sprint begins with the Daily Scrum Meeting

  • Daily ScrumParametersDaily15-minutesStand-upNot for problem solvingThree questions:

    What did you do yesterdayWhat will you do today?What obstacles are in your way?Chickens and pigs are invitedHelp avoid other unnecessary meetingsOnly pigs can talk

  • Daily ScrumIs NOT a problem solving sessionIs NOT a way to collect information about WHO is behind the scheduleIs a meeting in which team members make commitments to each other and to the Scrum MasterIs a good way for a Scrum Master to track the progress of the Team

  • Scrum FAQsWhy daily?How does a project get to be a year late?One day at a time. Fred Brooks, The Mythical Man-Month.Can Scrum meetings be replaced by emailed status reports?NoEntire team sees the whole picture every dayCreate peer pressure to do what you say youll do

  • Sprint Review MeetingTeam presents what it accomplished during the sprintTypically takes the form of a demo of new features or underlying architectureInformal2-hour prep time ruleParticipantsCustomersManagementProduct OwnerOther engineers

  • Sprint Retrospective MeetingScrum Team onlyFeedback meetingThree questionsStartStopContinueDont skip for the first 5-6 sprints!!!

  • Product BacklogA list of all desired work on the projectUsually a combination of story-based work (let user search and replace)task-based work (improve exception handling)List is prioritized by the Product OwnerTypically a Product Manager, Marketing, Internal Customer, etc.

  • Product BacklogRequirements for a system, expressed as a prioritized list of Backlog ItemsIs managed and owned by a Product OwnerSpreadsheet (typically)Usually is created during the Sprint Planning MeetingCan be changed and re-prioritized before each PM

  • Sample Product Backlog

  • From Sprint Goal to Sprint BacklogScrum team takes the Sprint Goal and decides what tasks are necessaryTeam self-organizes around how theyll meet the Sprint GoalManager doesnt assign tasks to individualsManagers dont make decisions for the teamSprint Backlog is created

  • Sprint Backlog during the SprintChangesTeam adds new tasks whenever they need to in order to meet the Sprint GoalTeam can remove unnecessary tasksBut: Sprint Backlog can only be updated by the teamEstimates are updated whenever theres new information

  • Sprint BacklogA subset of Product Backlog Items, which define the work for a SprintIs created ONLY by Team membersEach Item has its own statusShould be updated every day

  • Sprint BacklogNo more than 300 tasks in the listIf a task requires more than 16 hours, it should be broken downTeam can add or subtract items from the list. Product Owner is not allowed to do it

  • Sample Sprint Backlog

  • Sprint Burn down ChartDepicts the total Sprint Backlog hours remaining per dayShows the estimated amount of time to release Ideally should burn down to zero to the end of the SprintActually is not a straight lineCan bump UP

  • Information Radiator"Two characteristics are key to a good information radiator. The first is that the information changes over time. This makes it worth a person's while to look at the display... The other characteristic is that it takes very little energy to view the display."
