Texte du rabat

One of the joys of product development, whether it be software, service, or hardware, is getting it right. The way to get it right is to uncover the real business problem, and to write the requirements for the solution that best solves that problem.

Without the right requirements it is impossible to build the right solution. Mastering the Requirements Process, Fourth Edition, gives you an industry-proven process for getting to the essence of the business problem and then writing unambiguous and testable requirements for its solution.

This fourth edition is an almost complete rewrite that brings requirements discovery into today's world--it is the book for today's business analyst. Product owners and project leaders will also find it valuable as it explains how to discover precisely what the customer needs and wants, and to do it effectively in any business or project environment.

The book tells you how to:

Use the Volere requirements process to discover requirements in both traditional and agile environments
Incorporate off-the-shelf (OTS) solutions into your requirements discovery
Use artificial intelligence (AI) as part of your requirements discovery, and as part of your business solution
Use quickly sketched prototypes to explore the problem space
Understand functional and non-functional requirements
Write better agile stories
Make your requirements and stories measurable and testable using fit criteria
Use business events as the heartbeat of business analysis
Discover requirements in agile, commercial, and milspec project environments
Find and prioritize your customer segments
Leverage systems thinking when discovering requirements
Use story maps and other requirements repository techniques
Know which trawling techniques are the most effective for requirements discovery
Synchronize your requirements discovery with agile development teams
Make better decisions in the early days of a project to increase your chances of success
Employ the Volere requirements specification template (downloaded 10,000+ times) as the basis for your own requirement specifications "One of the most valuable things about this book is that it provides a process to follow that will get people asking the right questions and expand their perspective on the problem."
