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

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

CMMI Maturity LevelsLevel 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

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

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

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

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

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

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
