Transcript of Agile-Scrum Methodology-An Introduction

  • 1. Introduction to Agile with Scrum

2. Agenda Short introduc,on to Agile Scrum Overview How it works 2 3. Tradi4onal So7ware Project Failures Nearly 2 / 3 of the projects are signicantly over budget 64% of the features in a product are rarely used An average project exceeds its schedule by 100% 3 4. Main Causes Planning for comple4on of ac4vi4es rather than features. Progress not transparent to customers, and focus on ac4vi4es leading to missing-forgoRen features. Specializa4on leading to island culture and reduced involvement. Do not work on the basis of client priority, but o7en technical. Team starts late with important business needs Ignore uncertainty (changing insights / requests?) 5. Limita4ons of Waterfall "Waterfall" project approach is only possible if Problem is clear; Solu4on is known; Technique familiar; Problem has not changed; A sucient knowledge; Priori4es constant. 6. Agile Manifesto 7. Suppor4ng Agile Sentences 1. Our highest priority is to sa4sfy the customer through early and frequent delivery of valuable so7ware. 2. Deliver working so7ware frequently, from a couple of weeks to a couple of months, with a preference for the shorter 4me scale. 3. Working so7ware/product is the primary measure of progress. 4. Welcome changing requirements, even late in development 5. Business people and developers work together daily throughout the project. 6. Build projects around mo4vated individuals. Give them the environment and support they need, and trust them to get the job done. 8. Agile Methodologies Extreme Programming (XP) Scrum Feature-Driven Development (FDD) Adap4ve So7ware Process Crystal Light Methodologies Dynamic Systems Development Method (DSDM) Lean Development 9. Scrum A scrum is a term from rugby. Scrum is a way of re-startafter minor violation, where agroup of players tries to pushthe ball obtain control. 10. Scrum Flow 11. Sprints Scrum projects consist of a series of "sprints" Typically 2-4 weeks in length. A xed constant length gives a beRer work rate. Features are designed, built and tested during a sprint. Customer can not change job during a sprint. Have a sprint goal. A brief statement about the focus of the work of the upcoming sprint. 12. Scrum Framework 13. Product Owner Is the voice of the customer. Denes the features of a product. Determines the release date. Responsible for the protability of a product. Its mandate is to make decisions. Priori4zes the product features based on market value Change features and priority every itera4on, if desired. Accepts or approves work results. 14. Team Complete (all skills) Self and self-learning No permanent jobs 5 to 9 people Work together, not individually. Involved Produc4ve and fun Preferably, cross-func4onal. 15. Scrum Master Is not a project manager! Facilitates the team. Responsible for the importa4on and compliance with Scrum values and prac4ces. Solves problems for the progress of projects iden4ed by the team, so that the goal of Sprint and the deliverables are met. Ensures that the team is fully focused, opera4onal and produc4ve. Ensures that all roles and func4ons work together. Shields the team from external disturbances during the sprint. 16. Scrum Framework 17. Sprint Planning 18. Sprint Planning 19. Daily Scrum Daily, 15 minutes, standing. Not meant to solve problems. Anyone outside the team may be present, only team members are ac4ve part (speaking). Helps to avoid unnecessary mee4ngs (e g weekly progress mee4ng) Are not intended to state the progress or management. What did you do yesterday? What you are going do today? Are there any restric4ons that the comple4on of the sprint at risk? 20. Daily Scrum 21. Sprint Review(Demo) The team presents the results of the last sprint through a demonstra4on of the func4onality built. Informal, no slides, max 2 hours. The whole team takes part in the demonstra4on. Stakeholders and managers are welcome to aRend. 22. Sprint Retrospec4ve Is held a7er each sprint Consider what works and what does not work. Priori4za4on of the improvement. Ac4on items are dened to ensure that real improvements takes place in the next sprint (s). The whole team takes part (Scrum Master, Product Owner, Team). Dura4on vary depending on the retrospec4ve approach, team size, length sprint. Usually 30-60 minutes 23. Scrum Framework 24. Product Backlog The requirements To Do list of all the work required in the project. Expressed from the user / client. Not how but why. By priority (by product owner.) Itera4ve (changes ok, for each sprint). Visible. Items es4mated eort required (by team). User story format: As I want so that . 25. Product Backlog 26. Sprint Backlog List of work done in the next sprint. Breakdown of features into tasks (1-16 hours). Tasks are not assigned to team members. (More variety and crea4vity. No knowledge islands) Tasks are es4mated by the team with Planning Poker. Tasks are picked based on the right priori4es and the skills of team member. Is usually visualized by a Scrum board 27. Planning Poker 28. Scrum Board 29. Scrum Board 30. Itera4on Burn-down Chart 31. Release Burn-down Chart 32. Deni4on of Done Is determined by the team Completed work must meet this deni4on Elements to consider include: Coding style Code comment Peer review Units tests Document Manual ??? 33. Scrum Flow Summary 34. Summary Scrum is (almost) Magic: Timely feedback. Focus on working product. Priori4ze on added value. Not plan ahead in detail. Self-management and responsibility. Clear roles and responsibili4es. 35. To be con4nued
