The time commitment you are willing to put into your team. Skill Set: Classes, abilities, skills that you bring to the robotics team. Roles you would like to take: Builder, programmer, captain, driver, research, promotions, fund raising, product owner, Scrum master Page 4 Describe a Dream Team. You may include names if you would like. No guarantees, but it will help me in finalizing the teams. Page 5: Sprint Backlog This page will have the tasks your team commits to complete during the next Sprint. At the start of each sprint (3 weeks) you will have another sprint backlog page.

Day 2: Learning Objectives Break into teams. Brainstorm different strategies for the robot your are designing. As a team, set a direction for the strategy your team will begin pursuing this season. As a team develop a problem statement for your team. First Shot at Teams Strategize: How is your team going to attack this problem? Go to the field in the back room Talk strategies with your team. Get on the field to get an understanding of the challenges. What skill sets will make the robot successful? What pair robots will make the best alliance?
Find some matches online to see how some of the design choices have played out. Go online to look at reveals or other mechanisms that do what you are hoping to do to help clarify you In your individual journals document the strategy/strategies your team wants to implement this season. The strategy will drive your design. Defining the Problem Use the info from your research, your strategy and your team discussions to create a three+ sentence definition describing what you want your robot to be able to do. This should be something you could put on a business card to market your robot to other teams. Make sure a copy of this is in your team and individual journals. Day 3: Learning Objectives Using your team strategy and problem statement develop specifications and constraints for your robot. Begin brainstorming ideas for your robot design.
Specifications and Constraints Specifications: What your robot can do/be Stable: Will not tip over if placed on a 45 degree angle High Traction: Will not slip when pushed with 8 lb. force Constraints: What your robot cant do/be Must fit into an 18x18x18 May not use more than 12 motors, or 10 with pneumatics As a team develop at least 8 specifications and 8 constraints for your robot. Use your team strategies to guide the specifications and constraints that you see as important to your design. Record these in your team and individual journals.
Brainstorming The goal is to generate as many ideas as possible to help you develop the best product as early as possible Brainstorming Rules Every person and every idea has equal worth Every (school appropriate) idea is a good idea! Encourage wild and exaggerated ideas Go for quantity at this stage, not quality Build on ideas put forward by others Time for the Storm Team Roles Recorder (Into the team Engineering Journal) Encourager Thought provoker(s) (Idea generators)
Rotate roles every 3 minutes Brainstorm and record ideas for your robot Ill tell you when to rotate rolls Day 5 Learning Objectives Research to find options for your design. Continue to brainstorm ideas for your design. Start assembling ideas, specifications and constraints to help in selecting your robot design. Research Each individual will use the internet to research ideas for your robot designs Research 5 minutes Share 5 minutes (Every person shares!) Add ideas to your brainstorm list Research 5 minutes
Share 5 minutes (Every person shares!) Add ideas to your brainstorm list Selecting your Design Direction The team will be using a Decision Matrix to help in determining your direction. Record this in your team journal and copy into your individual journal Prioritize: What is the best idea? Weigh the advantages and disadvantages of each alternative? Set up alternatives in a matrix for analysis (See next slide.) Mark the grid (Can use other scales) 1. + = 1: Better. (Above Average) 2. 0 = 0: No appreciable difference. (Average) 3. - = -1: Worse. (Below Average) Simple Decision Matrix

design Use the rating from the Decision Matrix to help you select the design. You do not have to select a particular design that rated highest in the Decision Matrix. Sometimes a robot that is OK at everything but good at nothing comes out high in the ranking Your team has the final say in your design direction, but you should be able to justify it. Record your design choice and why in your engineering journal. Using Scrum to Improve Teamwork, Communication, Quality and Speed STEM Projects Over the Years
How can I help students work more effectively in teams? Goals for this session You will have a basic understanding of The Principle behind Scrum: Agile Manifesto The People: Committed vs. Involved The Plane: Hands on Example The Process: From idea to product The Potential: You can see how it could help your students succeed. The Principle:
Agile Manifesto Scrum is one application of Agile product development. We are uncovering better ways of developing products by doing it and helping others do it. Through this work we have come to value: Individuals and interactions over processes and tools Working products 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. Why Scrum? Yahoos Survey of Teams that Switched to using Scrum
Improved Productivity (Productivity up 38%) Improved Morale (52% yes vs. 9% no) Improved Accountability/Ownership (62% yes vs. 6% no) Improved Collaboration/Cooperation (81% yes vs. 1% no) Improved quality (44% yes vs. 10% no) 85% of new users prefer to continue using Scrum Some Companies that use Scrum What is Scrum? Scrum is a way for teams to work together to develop a product. Product development, using Scrum, occurs in small pieces, with each piece building upon previously created pieces. Building products one small piece at a time
encourages creativity and enables teams to respond to feedback and change, to build exactly and only what is needed. From Industry to My Classroom (Robotics) Part 1. Pre-Scrum: Determined Initial Design Direction Defined what the robot is to do Set Specifications and Constraints Researched and Brainstormed Solutions Selected the Original Design Direction Part 2. Develop the product in Teams using Scrum Establish Roles Apply Process Role: Product Owner Represents the Customer to the Scrum Team.
Decides what will be built and in which order. (Organizes Product Backlog) Maximizes the Return on Investment (ROI) of the team. Decides when something is Done. Class: Role rotates between team members. People: Scrum Master (Team Leader) Servant Leader Conductor of Ceremonies (Meetings) Daily Scrum Sprint Planning Sprint Reviews
Sprint Retrospectives Monitoring and Tracking Shields the Team from distractions. Class: Runs the team meetings and helps eliminate impediments. People: Scrum Team A Scrum Team is a collection of individuals working together to deliver the requested and committed product increments. Scrum Master Product Owner

Scrum Getting Started Task I put together a list of potential tasks to help students generate their Sprint Backlog Sprint Planning Meeting Using the Link to potential items for your product backlog, as a team select items that you will commit to complete in the next two weeks. https://docs.google.com/spreadsheets/d/1GcX-He1I54ns9twiONBjoNB52D
P72vPJ7zqWnAndmx8/edit?usp=sharing There is also a link on the class website. Place items that you intend to complete, but cannot commit to completing in the next sprint. If you did not complete this on Monday Select Product Owner: Quality Control Select Scrum Master: Team Leader Build Sprint Backlog: Tasks you can get done by next Friday Sprint Daily Scrum Meeting: What was done yesterday? What do you intend to do today? What is getting in your way of success?
Work: Select a task Add your name to the sticky note Move the note to the Doing column When you finish a task, demonstrate it to your Product Owner. If it passes, the product owner signs off and the note is moved to the Done Column. At the end of the sprint your team will demonstrate the Done items. End of Sprint Meetings (At the end of the Sprint. I use 3-weeks for the Sprint Time Length) Outline for the Day on Friday Sprint Review Meetings: Demonstrate your product to the class Class gives feedback
