This course gives you hands-on experience using five basic requirement models to more efficiently and effectively elicit and analyze functional requirements. You’ll create Context Diagrams, Activity Models (aka workflow models), Domain Models (aka E-R models, class models, data models), Use Cases and State Models. You’ll gain proficiency at using these models in practical and agile ways to more precisely and concisely capture requirements without getting caught up in modeling semantics. You’ll see how these five models can enable you to gather more requirements earlier in the project, and why model-based requirements exhibit greater stability than those that are interview-based. The course will also sharpen your instincts for knowing when you’ve done enough requirements work to proceed, and where requirements risks remain.

2-day seminar
