An Application of Agile Principles to the Systems Engineering Process November 2, 2013 Presenter: Zain Malik Authors: Zain H. Malik, Dr. Enrique Campos-Nanez, Dr. Pavel Fomin, Dr. James Wasek by Zain Malik. Permission granted to INCOSE to publish and use

Overview & Purpose To illustrate the benefits of applying agile principles to the Systems Engineering Process • Systems Engineering Processes and Challenges • Agile Overview • Framework for Implementing Agile Principles into Systems Engineering Process • Case Study Demonstrating Proposed Method

Systems Engineering Models V-Model Spiral Model Detailed process control Prototypes Formal deliverables Activities Gate reviews Artifacts Waterfall Model Prototyping Model Improve speed Mass production applications Detect design flaws Sequential design process Documentation

Challenges of Traditional Systems Engineering Processes Implementation of the Systems Engineering Processes presents challenges depending upon the implementation model: ! Lack of up front information ! Cost vs. benefit of formal documentation ! Responding to change ! Requirements driven ! Lack of focus on customer satisfaction

Principles behind the Agile Manifesto Customer satisfaction Early and continuous delivery Changing requirements Performance to shorter timescale Work together throughout the project Sharing information Sustainable development Reducing unnecessary work Simplicity Self-organizing teams Lessons learned s: http://agilemanifesto.org/principles.html

Traditional vs. Agile

Challenges to Agile Adoption 1. Teams had difficulty collaborating closely 8. Compliance reviews were difficult to execute within an iteration timeframe 2. Procurement practices may not support Agile projects 9. Timely adoption of new tools was difficult 3. Teams had difficulty transitioning to self- 10. Federal reporting practices do not align with directed work Agile 4. Customers did not trust iterative solutions 11. Technical environments were difficult to establish and maintain 5. Staff had difficulty committing to more timely and frequent input 12. Traditional artifact reviews do not align with Agile 6. Teams had difficulty managing iterative requirements 13. Agile guidance was not clear 7. Agencies had trouble committing staff 14. Traditional status tracking does not align with Agile 12-681 Effective Practices and Federal Challenges in Applying Agile Methods

Application & Lessons Learned Applying Agile Principles to the systems engineering lifecycle process ! Small teams with direct link to sponsor ! Give authority to make decisions ! Allow outside help as needed ! Co-locate leaders ! Use interactive design reviews ! Tailor out irrelevant processes ! Test and analyze as fast as possible
