    Each chapter utilizes case studies and numerous examples. Mathematical and technical sections can be skipped without loss of continuity. Most textbooks do not include models and decision support systems robust enough for industry, but that is not true of this new edition.The accompanying CD-ROM also features the return of two simulations, the Computerized Beer Game and the Risk Pool Game and a computerized tool. These simulations help users develop and execute supply chain contracts while also illustrating many of the concepts discussed in the text.

However, there are still challenges and many surround the Product Owner role: scaling Scrum, sustaining quality, delivering and measuring value, providing team leadership, being a part of organizational transformation, and simple survival are all still in play. In other words, the role is still just plain HARD. The Second Edition of Scrum Product Ownership is being delivered to help with today’s challenges. It has more practical advice, real-world tactics, and more stories. It provides a framework of ideas to help today's Product Owners and their teams to better “Deliver the Goods”. However, it remains true to its heritage of guiding you towards becoming a GREAT Product Owner…from the Inside Out.

     In The Essence of Watercolour Hazel shows how wonderfully versatile and beguiling the medium of watercolour is and how to get the most out of it. Hazel stresses how important it is to understand the characteristics of the medium in order to exploit it to the full.  She encourages the reader to explore the properties of watercolour and to be unafraid of strength of colour and brushstroke.Hazel shows through demonstration and projects that tone is king in watercolour and illustrates how to paint light with the use of shade. Armed with this understanding she demonstrates that watercolour is not such an unforgiving medium after all: accidents and mistakes can be disguised, overridden and corrected.The Essence of Watercolour is a culmination of many years of Hazel's teaching and demonstrating, in which she offers inspirational insights into the secrets of watercolour painting and encourages artists to take their art to the next level.

    In its most simple form, earned value equates to fundamental project management. This is not a new book, but rather it is an updated book. Authors Quentin Fleming and Joel Koppelman have made some important additions. In many cases, there will be no changes to a given section. But in other sections, the authors have made substantial revisions to what they had described in the first edition. Fleming and Koppelman’s goal remains the same with this update: describe earned value project management in its most fundamental form, for application to all projects, of any size or complexity. Writing in an easy-to-read, friendly, and humorous style characteristic of the best teachers, Fleming and Koppelman have identified the minimum requirements that they feel are necessary to use earned value as a simple tool for project managers. They have also witnessed the use of simple earned value on software projects, and find it particularly exciting. Realistically, a Cost Performance Index (CPI) is the same whether the project is a multibillion-dollar high-technology project, or a simple one hundred thousand-dollar software project. A CPI is a CPI … period. It is a solid metric that reflects the health of the project. In every chapter, Fleming and Koppelman stick with using simple stories to define their central concept. Their project examples range from peeling potatoes to building a house. Examples are in round numbers, and most formulas get no more complicated than one number divided by another. Earned Value Project Management—Second Edition may be the best-written, most easily understood project management book on the market today. Project managers will welcome this fresh translation of jargon into ordinary English. The authors have mastered a unique "early-warning" signal of impending cost problems in time for the project manager to react.

    Students will find concepts easy-to-understand through the clear writing style and full-color figures that illustrate current technology and trends.

This approach, combined with motivating tools such as the SCR Associates interactive Web-Based Case Study, Systems Analyst's Toolkit, the Student Study Tool on CD-ROM, and more, makes Systems Analysis and Design, Seventh Edition a wise and exciting choice for your introductory systems analysis and design class.
