What is a Daily Scrum Meeting? 9. What is Team Foundation Server (TFS)? 10. What is the different Phases involved in Software Engineering?

3 Explain Plan-driven Software Development in general

4 Plan-driven Software Development Traditional methods for developing software, sequential processes, the different phases involved are executed in a spesific order. Plan-driven methods involves detailed documentations in each phase. Phases involved: Requirements, Design, Implementation, Testing, Deployment and Maintenance

5 Give some examples of such Plan-driven Software Development methods

6 Traditional Plan-driven vs. Agile Software Development Processes Traditional Agile Waterfall Spiral Scrum Lean exreme Programming V-model FDD TDD "Cannot" go to next phase before previous phase is finished More flexible, Iterative and Incremental Approach

7 Explain Agile Software Development in general

8 Agile A group of software development methods Iterative approach Incremental: Software available to Customers every 2-4 weeks Self-organizing and cross-functional Teams Refactoring Examples: Scrum extreme Programming (XP) 8

9 Give some Examples of Agile Software Development methods

10 Traditional Plan-driven vs. Agile Software Development Processes Traditional Agile Waterfall Spiral Scrum Lean exreme Programming V-model FDD TDD "Cannot" go to next phase before previous phase is finished More flexible, Iterative and Incremental Approach

11 Explain the Waterfall method

12 Planning to create a new Software Requirement Not Finished? -Go back and Fixit! The Waterfall Model Finished Design Not Finished? -Go back and Fixit! Finished Implementation Not Finished? -Go back and Fixit! A Sequential Process Finished Testing Finished You cannot go to next phase before finsihed the previous phase Not Finished? -Go back and Fixit! Deployment Maintenance Software Finished

13 Explain some features used in extreme Programming (XP)

14 exreme Programming (XP) An Agile method Pair Programming Code Reviews Refactoring Unit Testing Standup Meetings 14

15 extreme Programming (XP) 15

16 What is Scrum?

17 What is Scrum? Scrum Basics (15min): Scrum in 7 Minutes: Scrum in 2 Minutes:

18 Scrum Members: Scrum Product Owner Sprint Backlog Stakeholders Scrum Process: Product Backlog Scrum Master Development Team 3-9 persons Daily Scrum Meetings Max 15 min. Sprint Review Sprint Planning

19 The Scrum Method Testing More Flexible No Finished? Yes Deliver Software Implementation Deployment Maintenance Iterations Sprints Design Sprint Backlog Planning Product Backlog Requirements Analysis Less Documentation

20 What is a Daily Scrum Meeting?

21 Daily Scrum Meeting 3 Questions: 1. What did you do yesterday? 2. What shall you do today? 3. Any Problems? Purpose with the Daily Scrum Meeting: - Synchronize activities and create a plan for next 24 hours. - Track Progress 21

22 Daily Scrum Meeting They are short (max 15 min) - and usually stand up meetings in the hallway Scrum at Microsoft: Bad Scrum Meeting Example: 22

23 Product Backlog Sprint Backlog Taskboard Daily Scrum Meeting

24 What is Team Foundation Server (TFS)?

25 What is TFS? Team Foundation Server (TFS) is an Application Lifecycle Management (ALM) system, i.e., the system takes care of all aspects in software development from planning, requirements, coding, testing, deployment and maintenance. TFS is a Source Code Control (SCC), Bug Tracking, Project Management, and Team Collaboration platform Tightly integrated with Visual Studio as Microsoft is the vendor of both Visual Studio and TFS Cloud based edition (Hosting Service): Visual Studio Online (former: Team Foundation Service ) 25

26 Application Lifecycle Management, ALM ALM Tools: Tools that facilitate and integrate: Requirements Management, Architecture, Coding, Testing, (Bug) Tracking, And Release Management (-> Software Development!) There exist a lot of such tools (TFS, Jita, etc ) We will use Team Foundation Server (TFS) from Microsoft, since it is tightly integrated with Visual Studio 26

27 Team Foundation Server (TFS) is an Application Lifecycle Management (ALM) system The Software Development Lifecycle (SDLC) Deployment Maintenance Planning SDLC Management Project Testing Team Management Bug Tracking MS Project Foundation Requirements Visual Studio MS Excel Analysis Server Implementation Collaboration Platform Source Code Control Scrum Agile (SCC) Design Visual Studio Online

29 What is the different Phases involved in Software Engineering?

30 Testing Implementation Deployment Maintenance The Software Development Lifecycle (SDLC) Planning Requirements Analysis Design

31 Planning Requirements Design

32 Implementation Testing Deployment
