Introduction to Scrum
What are the 1st and 2nd Parts of Sprint Planning Meetings?
1st Part: ---- Creating Product Backlog ---- Determining the Sprint Goal. ---- Participants: Product Owner, Scrum Master, Scrum Team 2nd Part: ---- Participants: Scrum Master, Scrum Team ---- Creating Sprint Backlog
What does Product Backlog mean?
A list of all desired work on the project -- Usually a combination of ---- story-basedwork("letusersearchandreplace") ---- task-basedwork ("improveexceptionhandling") List is prioritized by the Product Owner ---- Typically a Product Manager, Marketing, Internal Customer, etc. Requirements for a system, expressed as a prioritized list of Backlog Items Is managed and owned by a Product Owner Spreadsheet (typically) Usually is created during the Sprint Planning Meeting Can be changed and re-prioritized before each PM
Describe a Sprint
A month-long iteration, during which is incremented a product functionality NO outside influence can interfere with the Scrum team during the Sprint Each Sprint begins with the Daily Scrum Meeting Scrum projects make progress in a series of "sprints" Analogous to XP iterations Sprints are timeboxed so they always have a fixed start and end date, and generally they should all be of the same duration Target duration is one month ---- +/- a week or two ---- But, a constant duration leads to a better rhythm Product is designed, coded, and tested during the sprint
What goes into making a Sprint Backlog?
A subset of Product Backlog Items, which define the work for a Sprint Is created ONLY by Team members Each Item has it's own status Should be updated every day No more than 300 tasks in the list If a task requires more than 16 hours, it should be broken down Team can add or subtract items from the list. Product Owner is not allowed to do it
What happen in a Sprint Review?
A successful review results in bidirectional information flow 1. People who are not on the scrum team get to sync up on the development effort and help guide its direction 2. scrum team members gain a deeper appreciation for the business and marketing side of their product by getting frequent feedback on the convergence of the product toward delighted customers or users
How are Agile methods considered?
Agile methods are considered ---- Lightweight ---- People-based rather than Plan-based Several agile methods ---- No single agile method ----- XP most popular No single definition Agile Manifesto closest to a definition ---- Set of principles ---- Developed by Agile Alliance
What do Agile proponents believe is wrong with current software development?
Agile proponents believe Current software development processes are too heavyweight or cumbersome Too many things are done that are not directly related to software product being produced Current software development is too rigid Difficulty with incomplete or changing requirements Short development cycles (Internet applications) More active customer involvement needed CMM focuses on process
What happens in a Sprint Backlog during the Sprint?
Changes ---- Team adds new tasks whenever they need to in order to meet the Sprint Goal ----- Team can remove unnecessary tasks ---- But: Sprint Backlog can only be updated by the team Estimates are updated whenever there's new information
Daily Scrum
Is NOT a problem solving session Is NOT a way to collect information about WHO is behind the schedule Is a meeting in which team members make commitments to each other and to the Scrum Master Is a good way for a Scrum Master to track the progress of the Team
Sprint Retrospective Meeting?
Occur after sprint review and before the next sprint planning Focus on continuous process improvement Scrum Team only Feedback meeting Three questions Start Stop Continue
Describe Sprint Execution
Once the scrum team finishes sprint planning and agrees on the content of the next sprint Guided by Scrum master's coaching, performs all of the task-level work necessary to get the features done "done" means there is a high degree of confidence that all of the work necessary for producing good- quality features has been completed The team members define their own task-level and self-organizing in any manner they feel is best for achieving the sprint goal
What are Artifacts of Scrum?
Product backlog Sprint backlog Potential shippable product increment
Name the Scrum Activities and Artifacts
Product backlog Sprint planning Sprint backlog Daily scrum Sprint execution Potentially shippable product increment Sprint review Sprint retrospective
What are the roles of Scrum?
Product owner Scrum master Development team
Name 10 out of 20 things the Scrum Master does?
Represents management to the project Responsible for enacting Scrum values and practices Removes impediments Ensure that the team is fully functional and productive Enable close cooperation across all roles and functions Shield the team from external interferences Scrum master is a leader, not a manager Help the team to understand and embrace the Scrum values, principles, and practices As a coach, provides leadership and helps the scrum team to their own organization-specific Scrum approach Help managing the challenges occur during a Scrum adoption As a facilitator, the Scrum master helps the team resolve issues and make improvement to its use of Scrum Responsible for protecting the team from outside interference, and take a leadership role in removing impediments that inhibit team productivity
Name 10 out of 20 things that the Product Owner does?
Responsible for what will be developed and in what order Is the empowered central point of product leadership The single authority responsible for deciding which features and functionality to build and the order to build Maintains and communicates to all other participants a clear vision of what the team is trying to achieve He is responsible for the overall success of product 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.
What is Scrum?
Scrum is an agile approach for developing innovative products and services Begin by creating a product backlog - a prioritized list of the features and other capabilities need to develop a successful product Guided by the product backlog, you always work on the most important or highest-priority items first When you run out of resources (e.g., time, money), any work that didn't get competed will be of lower priority than the completed work
What is Scrum Framework?
Scrum is not a standardized process where you methodically follow a series of sequential steps that guaranteed to produce on time, on budget, a high-quality product Scrum is a framework for organizing and managing work The scrum framework is based on a set of values, principles and practices that provide the foundation to which your organization will add its unique implementation of relevant engineering practices and your specific approaches for realizing the scrum practice The result is a version of scrum that is uniquely yours
How does Sprint Goal to Sprint Backlog work out?
Scrum team takes the Sprint Goal and decides what tasks are necessary Team self-organizes around how they'll meet the Sprint Goal Manager doesn't assign tasks to individuals Managers don't make decisions for the team Sprint Backlog is created
What are the characteristics of Scrum?
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"
What are Activities of Scrum?
Sprint Sprint planning Daily scrum Sprint execution Sprint review Sprint retrospective Product backlog grooming
What does Inspect-and-Adapt activities mean?
Sprint review - product Sprint Retrospective - process
What does Sprint Review Meeting entail?
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 Participants Customers Management Product Owner Other engineers
What are the iterations in scrum?
The work itself is performed in short, timeboxed iterations, which usually range from a week to a calendar month During each iteration, a self-organizing, cross-function team does all of the work - design, implementing and testing - required to produce completed, working features that could be put into production To start each iteration, the team plans with high-priority subset of the product backlog to create in the upcoming iteration At the end of iteration, team review the completed features with stakeholders to get feedback. Based on the feedback, the product owner and team can alter both what they plan to work on next and how the team plans to do the work
Name 10 out of 20 things the development team includes.
Traditional software development has various job types, such as architect, programmer, tester, UI designer, DB admin etc Scrum defines the role of a development team, which is simply a diverse, cross-functional collection of these types of people who are responsible for designing, implementing, and testing the desired product The development team must do all of the work to produce one or more vertical slices of working product functionality each sprint So we need a team that is skilled at all of those tasks Typically 5-10 people Cross-functional QA, Programmers, UI Designers, etc. Members should be full-time May be exceptions (e.g., System Admin, etc.) Teams are self-organizing What to do if a team self-organizes someone off the team?? Ideally, no titles but rarely a possibility Membership can change only between sprints
Scrum FAQs
Why daily? -- "How does a project get to be a year late?" "Onedayatatime." Fred Brooks, The Mythical Man-Month. Can Scrum meetings be replaced by emailed status reports? No Entire team sees the whole picture every day Create peer pressure to do what you say you'll do
What is the Agile Manifesto?
A Statement of Values Individuals and interactions over processes and tools Working software over comprehensive documentation Customer collaboration over contract negotiation Responding to change over following a plan http://www.agilemanifesto.org
What are the parameters of Daily Scrum and what are the Three questions you should ask?
Parameters Daily 15-minutes Stand-up Not for problem solving Three Questions: 1. What did you do yesterday 2. What will you do today? 3. What obstacles are in your way? Also Who are involved (chicken), who are committed (pig) Only pigs should talk Chickens should attend as observers
How would you describe Scrum in 100 words?
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. 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.
What are the disadvantages of classical methods of software development?
§ huge effort during the planning phase § poor requirements conversion in a rapid changing environment § treatment of staff as a factor of production
