The new Software Requirements Memory Jogger by Ellen Gottesdiener is a must for every business analyst and project manager who deals with requirements management -- and that's probably everyone.
Its compact format makes it a valuable reference to have available for a quick review, and its low cost makes it a good personal tool for every team member involved in requirements activities.
The book is logically organized into the major activities of requirements management: preparation (Ellen calls this 'setting the stage'), elicitation, analysis, specification, validation, and requirements management. Each major activity has a large number of applicable tools that create the appropriate outputs for that activity. Within the elicitation activity there are at least 10 tools, and each one is described in enough detail to provide a perspective for appropriateness in your own project situation. All the activities are detailed in this fashion, and the book also has examples and usage tips.
Ellen's chapter on project types, and considerations for requirements management based on these project types is valuable for project managers and analysts structuring their project plans' tasks related to the requirements phase.
This is a great contribution to the requirements management field, and should be in every project manager's library.
