"If the purpose is to create one of the best books on requirements yet written, the authors have succeeded." —Capers Jones It is widely recognized that incorrect requirements account for up to 60 percent of errors in software products, and yet the majority of software development organizations do not have a formal requirements process. Many organizations appear willing to spend huge amounts on fixing and altering poorly specified software, but seem unwilling to invest a much smaller amount to get the requirements right in the first place. Mastering the Requirements Process, Second Edition , sets out an industry-proven process for gathering and verifying requirements with an eye toward today's agile development environments. In this total update of the bestselling guide, the authors show how to discover precisely what the customer wants and needs while doing the minimum requirements work according to the project's level of agility. Features include The Volere requirements process—completely specified, and revised for compatibility with agile environments A specification template that can be used as the basis for your own requirements specifications New agility ratings that help you funnel your efforts into only the requirements work needed for your particular development environment and project How to make requirements testable using fit criteria Iterative requirements gathering leading to faster delivery to the client Checklists to help identify stakeholders, users, nonfunctional requirements, and more Details on gathering and implementing requirements for iterative releases An expanded project sociology section for help with identifying and communicating with stakeholders Strategies for exploiting use cases to determine the best product to build Methods for reusing requirements and requirements patterns Examples showing how the techniques and templates are applied in real-world situations This is the eBook version of the printed book.

Requirements are a crucial ingredient of any successful project. This is true for any product--software, hardware, consumer appliance, or large-scale construction. You have to understand its requirements--what is needed and desired--if you are to build the right product. Most developers recognize the truth in this statement, even if they don't always live up to it.

Far less obvious, however, is the contribution that the requirements activity makes to project management. Requirements, along with other outputs from the requirements activity, are potent project management tools.

In Requirements-Led Project Management, Suzanne and James Robertson show how to use requirements to manage the development lifecycle. They show program managers, product and project managers, team leaders, and business analysts specifically how to:

• Use requirements as input to project planning and decision-making
• Determine whether to invest in a project
• Deliver more appropriate products with a quick cycle time
• Measure and estimate the requirements effort
• Define the most effective requirements process for a project
• Manage stakeholder involvement and expectations
• Set requirements priorities
• Manage requirements across multiple domains and technologies
• Use requirements to communicate across business and technological boundaries

In their previous book, Mastering the Requirements Process, the Robertsons defined Volere--their groundbreaking and now widely adopted requirements process. In this second book, they look at the outputs from the requirements process and demonstrate how you can take advantage of the all-important links between requirements and project success.

Ideas for Solutions The Volere Requirements Specification Template is intended for use as a basis for your requirements specifications. The template provides sections for each of the requirements types appropriate to today's software systems. You may download the template from the Volere site and adapt it to your requirements gathering process and requirements tool. The template can be used with Requisite, DOORS, Caliber RM, IRqA and other popular tools see http://www.volere.co.uk/tools.htm By Suzanne Robertson, James Robertson.
