1 02 | Define an Effective End-to-End Software Development Lifecycle Steven Borg | Co-founder & Strategist, Northwest Cadence Anthony Borton | ALM Consultant, Enhance ALM

2 Understand the value of an end-to-end view of Application Lifecycle Management (ALM) tools and practices Explain the benefits of fast feedback Implement strategies to reduce end-to-end cycle time Implement strategies to improve software quality Implement strategies to reduce waste Create a process improvement plan Module Overview

3 Tips This section is all about attitude and mindset, not knowing specific details. Having the right mindset will get you through nearly all of the questions, without having to focus on specific technical details.

4 Microsoft Virtual Academy Understand the value of an end-to- end view of Application Lifecycle Management (ALM) tools and practices

5 What the Study Guide says… Understand the value of an end-to-end view of Application Lifecycle Management (ALM) tools and practices. –understanding that an observable problem may be indicative of a more general process issue –explaining the difference between optimizing a piece of the ALM process such as manual testing and optimizing the entire ALM process

6 Work Item Traceability and Flow

7 Value delivery impediments

8 Team barriers = Value delivery impediments |

9 Teams without barriers deliver continuous value Continuous value delivery

10 Visual Studio ALM Teams without barriers. Continuous value delivery Deliver

11 Microsoft Virtual Academy Explain the benefits of fast feedback

12 What the Study Guide says… Explain the benefits of fast feedback. –explaining the importance of fast feedback related to communicating requirements –explaining the benefits of end customer feedback to early software iterations

13 Feedback Loops Measure Adjust

14 Feedback Loops Measure Adjust

15 Problems with Slow Feedback Introduce more work into the system –Long time between code and bug fix makes it harder for developer –Long time between bug find and bug fix verification makes it harder for the tester –Added complexity –More context switching Lowers overall productivity

16 New Tools to speed feedback Requirements - PowerPoint Storyboarding Customer Feedback - Feedback Client

17 PowerPoint Storyboards

18 Feedback Client

19 Microsoft Virtual Academy Implement strategies to reduce end- to-end cycle time

20 What the Study Guide says… Implement strategies to reduce end-to-end cycle time. –identifying bottlenecks in the delivery process –understanding the relationship between work in process (WIP) and cycle time –identifying metrics that highlight bottlenecks –creating potential solutions whose effectiveness can be validated

21 Identifying Bottlenecks

22 DEMO Microsoft Virtual Academy Relationship between Work in Process and Cycle Time

23 Little’s Law (Two Minutes of Math) Delivery Rate = Work-in-Progress ÷ Lead Time implies Lead Time = Work-in-Progress ÷ Delivery Rate thus WIP is a LEADING metric for Lead Time

24 Key metrics for identifying bottlenecks Leading indicators –Queue sizes –Batch Sizes Lagging indicators –Velocity Other metrics: –Rework costs –Bug trends

25 Pay Attention to Queues

26 CLOSE Attention to Queues

28 Microsoft Virtual Academy Implement strategies to improve software quality

29 What the Study Guide says… Implement strategies to improve software quality. –identifying process steps that introduce defects –understanding the end-to-end quality process –bringing quality efforts early in the development cycle

30 Conventional QA in the Modern app lifecycle QA Testing post implementation. Mostly manual with limited automation. UAT UAT post implementation and systems testing Operations readiness verification Pre-deployment verification Document requirements as BRDs and functional specs Write code to implement requirements

31 Continuous quality Shortened cycle times

32 User Interface Services Business Processes Business Rules and Logic Service integrations Data access Identity Data

33 Microsoft Virtual Academy Implement strategies to reduce waste

34 What the Study Guide says… Implement strategies to reduce waste. –identifying wasteful activities –creating strategies to eliminate waste –measuring the effectiveness of waste removal activities

35 What is waste? Inventory - Incomplete work. Work not in production Overproduction - Rarely used features Processing – Unneeded or excessive documentation / Looking for data Transport – Handovers, context switching Excessive Motion - Task Switching (Working on several projects in parallel, 20% loss) Waiting - Delays (caused by large batches, or too much work-in- process) Rework due to defects- Bugs

36 Dealing with Waste Finding Waste: –Look for delays or bottlenecks in your software development. –Work backward to identify the cause. –The cause is likely wasteful. Eliminating Waste: –Depends… –Likely, focus on continuous improvement and cycle time reduction Key metrics: –Cycle time reduction –Rework costs –Bug trends

37 Microsoft Virtual Academy Create a process improvement plan

38 What the Study Guide says… Create a process improvement plan. –creating strategies for implementing organizational change –identifying key metrics to be tracked during the improvement effort –creating consensus for the change

39 Key metrics Business value Rework costs Cycle time Bug trends Queue sizes Batch Sizes

40 Visit for an overview of the theory, and how theory aligns with the Visual Studio toolshttp://www.visualstudio.com/alm Focus on reducing cycle time, speeding feedback, small batch sizes, breaking down barriers, fast communication, minimally viable products and building quality in If you’re not convinced focusing on completing things faster with high quality is the most important thing, fake it for the test. For tools, understand Storyboarding and the Feedback Client
