Best Practices in Requirements Engineering. Must-Have.

How do you know if you have good software requirements? Some use the simple technique of checking if the requirements definition is complete, clear, and consistent. Every book on requirements engineering has some variation of this theme and in this book, you are advised to check if the requirements statement is complete, correct, feasible, necessary, prioritized, unambiguous, and verifiable. If you haven't used techniques like this one before, it is definitely a good idea to pick up a solid book like this one on the best practices in requirements engineering. There are several good books in the market on the topic of software requirements and this is one of the best ones out there. I found three other books that complement this one - Requirements Engineering by Kotonya and Sommerville (used more as a textbook), Managing Software Requirements by Leffingwell and Widrig (part of the Object Technology Series), and Effective Requirements Practices by Ralph R. Young (comes with a CD-ROM). If you are a project manager, business analyst or anyone that has a lot to lose because of bad requirements, you will benefit tremendously from this current book being reviewed. The book is divided into three parts - What and Why, Development, and Management of Software Requirements. The part names are self explanatory. This book is very readable and is full of best practices that stand true to their name! The unique things about this book - in chapter 2, the author outlines the Requirements Bill of Rights for Software Customers and the Requirements Bill of Responsibilities for Software Customers. When I first read this, I felt like every customer has to read this before attempting a software project. Chapter 10 has an excellent description of different diagrams useful in requirements documentation - DFD (data flow diagram), ERD (entity-relationship diagram), STD (state transition diagram), dialog map, and class diagrams. I think all books on software requirements should ideally have some variation of these topics. Important topics like traceability are given an excellent treatment in this book but the only thing lacking is how to manage requirements in software processes involving iterations (the mainstay of the Rational Unified Process and other newer software development methodologies). There are only 13 pages devoted to this topic and even then it is indirect - Chapter 12: Risk Reduction Through Prototyping. Otherwise, I have no complaints about this book and I believe that it is a basic to intermediate in level (definitely not an advanced book). Overall, I believe it indeed captures the best practices in the field of requirements engineering. It is also a good price, so enjoy!

Managing requirements in real life

This book faces a lot of competition from other books, which are supposed to tell you how to manage software projects in general, and the requirements gathering process in particular.However, what sets this book apart from the vast majority of others is its absolute relevance (as opposed to being an arbitrary textbook). For example, this book recognizes the fact that often enough process improvements are deferred due to political reasons alone. The more you read it, the more you realize it addresses the same problems you have encountered while managing the requirements process.But what really sets this book apart is that it actually tells you how to solve these problems, by offering feasible solutions that could be easily implemented, gradually, in real life scenarios. This, basically, means that the book could actually HELP you.

A must for anyone affected by software system development

If you are looking for a very direct, down-to-earth approach to developing and managing requirements, this is the book for you. If you believe that managing requirements is overhead that you cannot support, you need to read this book. Karl takes a very practical approach to requirements development and management. He explains his approach in a succinct manner and provides very good examples to make his point. This book should be a mandatory read by all software development project managers, whether they come from the business or technical side of the business. Additionally, Karl's book makes good reading for anyone who is affected by the development of a software system such as business visionaries, end-users, quality assurance, business analysts, technical writers, trainers, and developers.

Software Requirements

Karl Wieger's book is destined to be classic in software requirements. It delivers a large set (over 40) no-nonsense best practices in highly readable, non-nonsense manner. I believe every project manager, IT (Information Technology) and business analyst, and IT account manager should read this book. Further, developers would do well to read it to gain critical insight into the 'big picture' of requirements engineering.The book is broken down into three sections: the case for requirements engineering best practices ("What and Why"), the requirements discovery, verification and validation process ("Software Requirements Engineering"), and the essentials of requirements management ("Software Requirements Management"). Throughout, the dual necessities of doing requirements right (verification) and doing the right requirements (validation) is addressed. Wiegers has thoroughly delved into the literature in the software requirements field. The text is liberally spiced with tidbits of data to support the business case for implementing these best practices. I found myself making notes in the inside cover and folding back pages to reference again as I read through the book.Early in the book, Wiegers presents a set of software engineering best practices which are classified into priority (high, medium, low) and difficulty (high, medium, low). Although you may disagree with the specific rankings for your shop, this table is an excellent example of modeling appropriate requirements engineering practices - prioritizing requirements! Other goodies abound. For example, a partial case study flows throughout the book which gives the reader enough of an idea of what a use case, dialog map, text requirement, etc. looks like to get the concept being resented. Each chapter ends with a concise list of suggested next steps, providing the reader with concrete actions to take to implement the practices covered in that chapter. In addition, there are numerous sample templates (e.g. Risk Item Tracking, Software Requirements Specification), several excellent checklists (e.g. Inspection Checklist for Software Requirements Spec, Software Elements Affected by a Proposed Change,), visual models (e.g. Requirements Traceability Links, Change Control Process) and a wonderful "bill of rights" for the software customer which boldly and directly asserts both rights and responsibilities of the customer. A set of example models is provided in the chapter called "A Picture is Worth 1024 Words". You will need to read other books or take training on the mechanics, notations and semantics of these models for visualized functional requirements. But the author covers the key models and their purpose succinctly. This book is easy to read, cuts to the chase, and provides a bounty of information that will wet our appetite to take action. This book is not a requirements engineering method or methodology, which would prescribe step-by-step protocols of tas

This book should become a classic in requirements writing

This is a great book. It provides clear and concise approaches to solving classic requirements problems. It is not just about software, it can be applied to any system or project. It is not written in software terms, it avoids the software worlds attempt to create new terms for everything. This is not a book by an academic but by someone who has worked in industry and solved problems, just like those that you face.The book includes templates, checklists and guidelines that are easy to use. I also liked the clean style of the book and it is very easy to read. You can apply all or part of the suggested process to your own projects.A more detailed review will appear in the Winter Issue of Insight, the magazine of the International Council on Systems Engineering (INCOSE)
