3. CMMI - Background • The Capability Maturity Model Integration (CMMI) is a process improvement method that integrates disparate organizational functions, sets improvement goals and priorities and provides guidance for quality and a point of reference for reviewing current processes • CMMI is predecessor to the Capability Maturity Model (CMM), first released in 1989, sponsored by DoD and developed by the Software Engineering Institute (SEI) at Carnegie Mellon University. • CMMI is currently maintained by a team comprised of DoD, industry and SEI members • CMMI Version 1.2 is slated for release in November 2007

4. CMMI Benefits • Is a conglomerate of internationally recognized best practices • Internationally recognized and adhered to organizational maturity model • Aids in linking management and engineering activities to business goals • Aids in implementing a robust maturity practice • Applicable to any product producing project, particularly large or Enterprise wide projects

5. CMMI Maturity Levels Level 1: Performed • Process is unpredictable, reactive in nature and uncontrolled Level 2: Managed • Process characterized for projects and is managed Level 3 Defined • Process characterized for the organization and is proactive Level 4: Quantitatively Managed • Process quantitatively measured and controlled Level 5: Optimizing • Process focused on continuous process improvement

6. CMMI Process Areas Level 2: Manager Configuration Management Measurement & Analysis Project Monitoring & Control Project Planning Process & Product Quality Assurance Requirements Management Supplier Agreement Management Level 3: Defined Decision Analysis & Resolution Integrated Project Management Organizational Process Definition Organizational Process Focus Organizational Training Product Integration Requirements Development Risk Management Technical Solution Validation Verification Level 4: Quantitatively Managed Quantitative Project Management Organizational Process Performance Level 5: Optimizing Casual Analysis & Resolution Organizational Innovation and Development

7. Requirements Development • The Requirements Development process area is defined to produce and analyze customer, product and product-component requirements • Requirements should address the needs of all relevant stakeholders and constraints resulting from the design solution • Requirements Development as defined by CMMI is relevant to any project in which a product is developed

8. Requirements Development Requirements Development is comprised of the following events: • Gathering and organizing stakeholder needs • Developing the product’s life-cycle specifications • Establishing customer requirements • Establishing product and product-component requirements

9. Requirements Development Requirements Development can be broken into 3 specific goals: • Develop Customer Requirements • Establish needs • Establish requirements • Develop Product Requirements • Develop Product and Product-Component Requirements • Allocate Product-Component Requirements • Discern Interface Requirements • Analyze and Validate Requirements • Develop Operational Concepts and Scenarios • Define Required Functionality • Validate Requirements with Comprehensive Methods

10. Requirements Development Requirements Development is important because: • Requirements are the backbone of design • The process helps ensure customer satisfaction • Adherence to the process signals CMMI Level 3 Maturity

11. Requirements Development Concerns surrounding Requirements Development include: • Process may be too long or cumbersome for smaller projects • Heavy reliance on outside organizations • Assumes that stakeholders understand what they want
