Karl Wiegers, Principal Consultant with Process Impact and author of 14 books, and Candase Hokanson, Business Architect and PMI-Agile Certified Practitioner at ArgonDigital, speak with SE Radio host Gavin Henry about software requirements essentials. They explore five different parts of requirements engineering and how you can apply them to any ongoing project. Wiegers and Hokanson describe why requirements constantly change, how you can test that you're meeting them, and why the tools you have at hand are suitable to start straight away. They discuss the need for requirements in every software project and provide recommendations on how to gather, analyze, validate, and manage those requirements. Candase and Karl offer in-depth perspectives on a range of topics, including how to elicit requirements, speak with users, get to the source of the business or user goal, and create requirement sets, models, prototypes, and baselines. Finally, they look at specifications you can use, and how to validate, test, and verify them. Brought to you by IEEE Computer Society and IEEE Software magazine.
