© Tasktop 2017 @mik_kersten @carmendeardo© Nationwide 2017 Our AGILE
Journey Began in 2006 7 AGILE The starting point was a Project Centric mindset with high start-up costs and inconsistent delivery We did not see the productivity and quality gains we desired, so we increased our focus on Agile practice maturity To reduce start-up costs and improve consistency, we established 20 agile “standing lines”2006 2012 CMMI Scaled up to 50 Agile Lines across 14 technology domains First Tasktop Integration: QA and Agile Lines (defects)
8.

© Tasktop 2017 @mik_kersten @carmendeardo Optimizing for linear flow Design for repeatability, minimize creative work This doesn’t work for software Waterfall and RUP are tried to make things linear Overly narrow DevOps are doing the same End-to-end software is not a linear manufacturing process, it’s a Value Stream Network
20.
© Tasktop 2017 @mik_kersten @carmendeardo Value Stream Network
21.
© Tasktop 2017 @mik_kersten @carmendeardo 70% integrate 3+ endpoints 40% connect 4 or more tools 66% use 4-8 integration patterns 300 value streams analyzed Your value streams are networks But most have an ad-hoc architecture
22.
© Tasktop 2017 @mik_kersten @carmendeardo Software architecture follows value stream, not vice versa APIs to minimize a team’s wait times Or structure follows value stream Reverse Conway’s law, Feature teams Value Stream Architect Defines integration and visibility strategy Designs end-to-end flow and feedback loops Core to your transformation Value Stream Architecture https://itrevolution.com/devops-books/
23.
© Tasktop 2017 @mik_kersten @carmendeardo Value Stream Integration Every best-of-breed tool is connected for end-to-end flow Single standard tool chain, can be specialized for countries, LOBs, investment horizons The tool chain becomes modular, supports change and specialization Value Stream Visibility Real-time view of all business value flows and bottlenecks Metrics are connected to business results Risk and compliance certification is built into the framework Framework

Pulled by Description Feature Story Requirements, User Stories User/Customers New business value added to the application, visible to the customer Defect Story Incident, bug User/Customers Fixes for quality problems that affect customer experience Security Story Vulnerability Security Officers, Auditors Fixes for weaknesses, flaws and vectors for exploits Tech Debt Story Architecture story Software Architects, Teams Improvement to the software architecture, invisible to the customer Value Stream Story IT for IT backlog Value Stream Architects Improvement to the value stream architecture, invisible to the customer
25.
© Tasktop 2017 @mik_kersten @carmendeardo Flow Measures Flow Measures
Description Example Lead Time Time from request to delivered artifact running in production Days from customer requesting a feature to using the requested feature. Cycle Time Time from work start to completion Hours from developer accepting a Feature Story to merging the finished implementation to master. Process time Time an artifact is actively worked on Cumulative days a Feature Story is actively worked on. Wait time Time from work request to work start Time zone delay in hours for an offshore team to start work on a Feature Story. Utilization Sum of process times of lead time (%) Low utilization for a Dev team with an external dependency Backlog Size Number of artifacts in the queue at a particular stage of the value stream The number of Security Stories on an Agile team’s backlog.

Type Description End-to-end Lead Time Velocity Time from customer request to improvement running in production Mean Time To Repair (MTTR) Responsiveness Round-trip time from support ticket, through Defect Story creation, diagnosis, fix through to delivery. Deployment frequency Repeatability Number of deploy per day/week Flow unit cost Cost Cost per flow unit per team Productivity Throughput Number of flow units delivered per team per release. New Business Value Ratio Value Proportion of Artifacts of type Feature Story delivered per release.
