  • Overview

    This course prepares the student to properly identify, define and confirm the customer’s true requirements when they are needed – prior to the design and development of the system. The key to every project’s success, accurately captured requirements are not only essential for meeting stakeholders’ expectations, but also to avoid costly delays, added cost for rework, and poor customer relations.

    Upon completion of the course, participants will be able to:

    • Detect early errors in analysis, design, and development (when it costs the least to correct)
    • Define solutions that meet stakeholder needs
    • Use modeling techniques to document and confirm functional requirements
    • Create an effective change management process
    • Develop and use a framework for the requirements development process
    • Employ validation and verification methods to ensure correctness
    • Minimize scope creep
    • Contribute to the development of best practices in requirements management for an organization
    • Identify key challenges to the requirements development process
    • Write clear and concise requirements
    • Develop a requirements traceability matrix and a requirements specification document
