1 Living Iteratively "Don't drive angry!" American Society for Quality Fall Conference November 3, 2016

2 Objectives 1. Identify the "right" opportunities to leverage iterative / incremental development (IID) 2. IID Exercise: "Living Iteratively" Time-Boxing Iterative Prototyping / Usability Iterative Stand-Ups

3 Waterfall Why IID? WHAT? HOW? WHY? IID Hybrid Hardware Installation

4 Why IID? Why? 100% 11% End-User Adoption Improved scope, less unused, unneeded functionality 10% Quality Lower cost due to less work 4% 125% Time-to-Value Benefits realization pulled from iterative releases rather than one single release at the project s end Traditional Approaches Source: Corporate Executive Board Expected Benefits Using IID

5 "Spar" with Change Why? Daily Focus Timely Risk / Impact Assessments Real-Time Communication

6 Conduct Quality Checkpoints Why? Daily Metrics Iterative Incremental Deliverable Sign-Offs

7 Build Value "One Success at a Time" Why? "Time-to-Value" Incremental Releases

8 IID Methodology How Iterations (Sprints)

9 IID Methodology How Incremental Iterative

10 Time-Boxing Picking a Date Study or Socialize? Student Syndrome wait until the very last minute to start their assignments Parkinson's Law work assigned expands to fill the allotted time

11 Rube Goldberg TIME-BOXED Exercise

12 Rube Goldberg "Hands-On" TIME-BOX Objective: 30 minutes: Needs: Pop a balloon! 25 minutes construction 5 minutes at end to showcase with other teams Race Track (10) Dominos (10) Pulley (20) POPPED Balloon! (40) Bonus Points: Mouse Trap (20) TOTAL Points Possible: 100 pts Pulley Examples:

14 Prototyping How Working model displaying limited functionality of the product under development. PERFECTION is your enemy! Rapid prototyping helps evolve customer requirements in the early stage of development. Prototypes can have business and technical dimensions.

15 Iterative Prototyping/Usability Gather Level 1 Requirements Create L1 Wireframe Gather Level 2 Requirements Create L2 Wireframe Conduct Interviews Gather Level 3 Requirements Create Prototypes Conduct End-User Trial Revise Prototypes Develop / Build Deliverables

16 Prototyping Case Study Seven Existing Screens Combine into One Screen

20 The Right Mindset How DEFEND DISCOVER!

21 Stand-Ups PURPOSE: Team alignment, focus, momentum, commitment Each team member answers three questions: 1. What did you do yesterday? 2. What will you do today? 3. Are there any obstacles in your way? Key Decisions Scope Alignment Resource Contentions Technology

22 Stand-Up Cadence Daily Stand-Ups 24 H 1-4 WEEKS Review Requirements Prioritized Chunking Master Schedule Deliverables time-boxed Tasks identified by team Team commitment Lessons-Learned

23 Stand-Ups - TIPS Standing promotes engagement Co-Location is critical Team visualization breeds accountability and collaboration Start and end ON TIME

24 Living Iteratively Iterative / Incremental approach promotes: High team interaction / creativity Heightened communication Alignment of expectations Early value realization Constant learning / improvement Product QUALITY + VALUE
