Not connecting software project management (SPM) to actual, real-world development processes can lead to a complete divorcing of SPM to software engineering that can undermine any successful software project. By explaining how a layered process architectural model improves operational efficiency, Process-Based Software Project Management outlines a new method that is more effective than the traditional method when dealing with SPM. With a clear and easy-to-read approach, the book discusses the benefits of an integrated project management-process management connection. The described tight coupling of the process world to the SPM world provides a high degree of completeness and accuracy necessary for effective project management. The author shows you that this process-based approach to SPM increases product quality, shortens time-to-market, reduces life cycle costs, facilitates short system test times, and increases developmental supply chain management (SCM) controls and total repeatability. This underlying process approach also actively involves SCM, software quality assurance (SQA), engineering, and accounting as part of your integrated SPM team for total success. Through examples and detailed explanations, Process-Based Software Project Management illustrates how this novel SPM approach is more profitable and time-efficient when compared to traditional SPM methods. The software manager, along with the support team, will finally all be on "the same page" to achieve SPM/engineering success.

Computational intelligence (CI) lies at the interface between engineering and computer science; control engineering, where problems are solved using computer-assisted methods. Thus, it can be regarded as an indispensable basis for all artificial intelligence (AI) activities. This book collects surveys of most recent theoretical approaches focusing on fuzzy systems, neurocomputing, and nature inspired algorithms. It also presents surveys of up-to-date research and application with special focus on fuzzy systems as well as on applications in life sciences and neuronal computing.

This title was first published in 2001: Product and particularly customer profitability are black holes in most managers' understanding of their business. Identifying customer revenue is easy but identifying what they cost - so we can understand whether or not they are profitable - is difficult. In a world in which competition, regulation and the increasing use of the Internet put ever greater pressure on margins it is vitally important to understand both product- and customer-profitability. Activity Based Management (ABM) enables you to do this. This book explains the power of using ABM to increase the profitability of your business. It provides step-by-step guidance on basic principles, comparisons between traditional methods, definitions of processes, activities and cost-drivers as well as details of data collection techniques and implementation steps. Through the book's numerous detailed examples a logical picture builds up of how to obtain the benefits that ABM can deliver. On its own ABM will change management decision-making: by showing how ABM also supports other profit improvement initiatives such as Business Process Reengineering, Shareholder Value Added and Customer Relationship Management, managers will learn how they can use the best possible toolkit to put their business firmly on the road to leaps in profitability.

This cross-disciplinary business book develops insight into the management of businesses operating in various economic sectors that take a proactive approach to the triple dimension of sustainability (economic, social and environmental), positioning itself as a key reference for both academics and practitioners in the wide area of business management. The concept of sustainability is today at the heart of international policies and debate, and plays a key role in deep changes to the organizational models of companies operating in a wide range of sectors of economic activity. In particular, this book aims to gain a deeper understanding of how stakeholder engagement can contribute to value co-creation both in the company and along the supply chain, and what distinguishes the differing involvement of stakeholders, in particular between public involvement and stakeholder participation. Each chapter of this book presents different modalities of stakeholder involvement and develops the concept of value co-creation from organizational and marketing perspectives. This book is recommended reading for those interested in the fields of stakeholder engagement and theory, sustainability, business studies, and sustainable development.

Utilizes advanced concepts, guidelines and requirements from the latest ISO 9000 and 10000 series of standards, as well as other models, including TQM (Total Quality Managment). The text shows how to define a policy and explain it clearly. It offers procedures for developing a quality manual, to be used by personnel performing quality-related functions and for external auditors and customers.

In an age when most business plans extend only to the next quarterly reporting period, the authors of this book propose an audaciously longer view of future planning. Reaching beyond the modern five or ten-year strategic plan, the authors take a cue from Kongo Gumi, a Japanese construction company launched in 578 AD that managed to thrive as a family-owned business for nearly 1500 years. With the 2010 publication of an international standard on social responsibility (ISO 26000), and increased attention to sustainability and sustainability reporting, many organizations today are heeding the call to operate with this standard in mind. However, once the guidelines are understood and the gaps measured, these same organizations often struggle during implementation. Leveraging many decades of combined experience in Quality Management and Product Development, the authors of this seminal book provide a proven solution to help you turn information into action. Defining exactly what social responsibility means, A Six Sigma Approach to Sustainability introduces SOFAIR, a six-step methodology for achieving sustainability through social responsibility performance improvement. This rigorous methodology uses Six Sigma, and other process improvement methods, as a basis for maximizing the efficiency and effectiveness of your organization's social responsibility performance improvement effort. The book explains and demonstrates the meaning of CISR (R) - continual improvement for social responsibility - and illustrates the six-step SOFAIR methodology with many examples. The authors explain how your existing organizational continual improvement efforts can be adapted to also focus on sustainability. Four case studies are provided that demonstrate the application of the methodology in manufacturing, healthcare, business processes, and everyday personal life. Finally, the authors provide 10 things you can do today as social responsibility action. Kongo Gumi represents the author's goal of sustainability, and prompts the question, "What will your organization look like, not in 5-10 years, but in fifteen centuries?" This book provides a way for you to take action to create a more sustainable environment where your customers, suppliers, employees, and communities are available for your organization for decades, and even centuries, to come. About the Book's Cover: The six hands of many colors encircling the globe represent the diversity of stakeholders engaged in the six-step SOFAIR Process, and the global impact of CISR (R).

Lean is about building and improving stable and predictable systems and processes to deliver to customers high-quality products/services on time by engaging everyone in the organization. Combined with this, organizations need to create an environment of respect for people and continuous learning. It's all about people. People create the product or service, drive innovation, and create systems and processes, and with leadership buy-in and accountability to ensure sustainment with this philosophy, employees will be committed to the organization as they learn and grow personally and professionally. Lean is a term that describes a way of thinking about and managing companies as an enterprise. Becoming Lean requires the following: the continual pursuit to identify and eliminate waste; the establishment of efficient flow of both information and process; and an unwavering top-level commitment. The concept of continuous improvement applies to any process in any industry. Based on the contents of The Lean Practitioners Field Book, the purpose of this series is to show, in detail, how any process can be improved utilizing a combination of tasks and people tools and introduces the BASICS Lean (R) concept. The books are designed for all levels of Lean practitioners and introduces proven tools for analysis and implementation that go beyond the traditional point kaizen event. Each book can be used as a stand-alone volume or used in combination with other titles based on specific needs. Each book is chock-full of case studies and stories from the authors' own experiences in training organizations that have started or are continuing their Lean journey of continuous improvement. Contents include valuable lessons learned and each chapter concludes with questions pertaining to the focus of the chapter. Numerous photographs enrich and illustrate specific tools used in Lean methodology Check: Identifying Gaps on the Path to Success Transactional Processes contains chapters on implementing Lean, Kanban systems, line balancing, Heijunka-leveling, and the +QDIP process plus case studies of machine shop and transactional implementations.

In 2001, we gathered a group of researchers in Nice, France to focus discussion on performance measurement and management control. Following the success of that conference, we held subsequent conferences in 2003, 2005, 2007, and 2009. This volume contains some of the exemplary papers that were presented at the most recent conference. Though the conference has been generally focused on performance measurement and management control and has included presentations on many facets of the topic, each year we have also focused on a particular theme of current interest. This year's theme was directed at innovative concepts and practices. This includes creative approaches to solving management challenges of performance and management control and improving organizational performance. It also includes the innovative use of empirical, analytical, experimental, and case based research. The contents of this book represent a collection of leading research in management control and performance measurement and provide a significant contribution to the growing literature in the area.

The ISO 9001/2 series of standards for Quality Managment Systems is of increasing importance to the food and drink industry; it functions as an outward and visible sign to customers that the industry has a defined quality management system that has been independently appraised and is regularly audited. ISO 9001/2 certification can enable a company to reduce the audit burden from a multitude of customers and can also help the manufacturer or distributor involved in auditing its own suppliers. Above all, it may improve the effectiveness of its own operation and profits.

"A highly readable and yet comprehensive book on network businesses that have become governable with the advent of cloud and big data computing. Vivek Kale is a master of simplifying the complex world of network theory and its relevance to business." -Jagdish N. Sheth, Charles H. Kellstadt Professor of Marketing, Emory University Agile Network Businesses: Collaboration, Coordination, and Competitive Advantage reflects the shift from traditional networks to virtual and agile networks that enable businesses to operate dynamically, thereby representing markets more closely. This book enables IT managers and business decision-makers to understand clearly what network businesses and enterprises are, what they can do for them, and how to realize them. Customers in geographically dispersed markets are demanding higher quality products in a greater variety, at lower cost, and in a shorter time. Thus, enterprises have moved from a few centralized and vertically integrated facilities to geographically dispersed networks of capabilities, competencies and resources, which are the core of network businesses. Enterprises are now constructing more fluid network businesses in which each member facility focuses on differentiation and relies increasingly on its partners, suppliers, and customers to provide the rest. Network businesses have emerged as an organizational paradigm for collaboration and coordination across loosely connected individual organizations. This pragmatic book: Introduces network solutions and distributed systems that are a first step towards enabling a network enterprise. It also gives a detailed description of networks and agent system that have paved the road to network enterprises. Describes the basics of service-oriented architecture (SOA), cloud computing, and big data that are essential to network enterprises. Details the distinguishing aspects of network enterprises, which include virtual enterprises, management of network enterprises, and collaborative network enterprises. Covers such major application areas as supply, manufacturing, e-business, platform, social and wireless sensor networks. Introduces decision networks in the context of supply chain networks This book reinterprets the traditional supply chain in terms of the flow of decisions, information, and materials, which leads to reconfiguring the traditional supply chain network into mutually separate decision networks (e.g., fourth-party logistics or 4PL), information networks (e.g., wireless sensor networks), and logistics networks (e.g., third-party logistics or 3PL).

Even though Six Sigma programs have successfully been implemented in practice, many IT departments remain skeptical of the process or are unaware of how the tools can be used to improve system development. Removing the mystique surrounding this technique, Six Sigma Software Development, Second Edition demonstrates how Six Sigma tools and concepts can be used to enhance the system development process. Revised and updated, this second edition clearly explains Six Sigma concepts and their application, maps Six Sigma concepts and tools to all aspects of system development, and proposes the use of Six Sigma tools to evaluate and improve the overall performance of the IT department. In addition to classic Six Sigma, the book introduces Design for Six Sigma (DFSS) and illustrates when and how its tools and techniques can be used to increase the robustness and reliability of a new system. It also shows how the judicious application of lean tools can reduce the complexity of IT processes, thus shortening the time needed to translate customer requirements into completed systems and increasing customer satisfaction.

This book is aimed at manufacturing and planning managers who struggle to bring a greater degree of stability and more effective use of assets to their operations, not realizing the degree to which production scheduling affects those objectives. It has been reported that 75% of the problems on the manufacturing floor are caused by activities outside the plant floor. Poor production scheduling strategies and systems are often the biggest contributors to the 75%. The book explains in detail that no scheduling strategy, and especially no transition to a different and better scheduling strategy, will succeed without strong commitment and guidance from senior leadership. Leadership must understand their active role in the transition, that people will feel uncomfortable and even threatened by change, and that they will need to be measured by different standards. Effective scheduling requires that following the schedule and production to plan is more important than trying to maximize each day's throughput. The book explains the advantages of a structured, regularly repeating schedule: how it can increase throughput, right-size inventory based on cycles and variabilities and therefore make it more usable, and improve customer delivery. It will explain the trade-offs between throughput, inventory, and delivery performance, how those trade-offs are actually decided in production scheduling, and how an appropriate scheduling strategy can make the trade-offs and their ramifications visible. It discusses several popular structured scheduling concepts, their similarities, and differences, to allow the readers to decide which might fit best in their environments. In addition, the authors discuss what makes an appropriate scheduling software system, and why a package designed for structured scheduling offers capabilities well beyond the Excel workbooks used by many companies, and how it offers much more design capability and ease of use than the finite scheduling modules in SAP or Oracle. Finally, the authors offer a proven roadmap for implementation, critical success factors necessary to achieve the full potential, and give examples of operations that have done this well. In addition, a guide for leaders and managers post-implementation is provided to help them fully exploit the advantages of a structured, repeating scheduling strategy.

Category management is one of the biggest contributors of commercial value in the area of procurement and supply chain. With a proven track record of successful delivery since the early 1990s, it helps organisations gather and analyse key data about their procurement spend before subsequently creating and delivering value-adding strategies that change the value proposition from supply chains. The aim of category management is to find long-term breakthrough strategies that help lift an organisation's commercial performance to a new level. Because of its strategic long-term orientation and complex execution, category management has long been the preserve of commercial consulting companies - in effect a 'black box' toolkit shrouded in expensive methodologies. This practical handbook lifts the lid on category management by providing readers with a step-by-step process and established toolkit that allows them a 'do-it-yourself' approach. Each activity is presented as a simple tool or technique for practitioners to apply to their own organisations. To support each activity, easy-to- use templates and checklists have been provided, together with simple but practical hints and tips for implementation. This handbook is a 'must read' for all procurement and supplychain managers looking to find significant improvements in their organisations. Its practical approach cuts through long-winded consultant-speak and provides an easy-to-use practical toolkit for everyday application.

This book details most common statistical process control tools with many examples for high-volume production. It aims to make elements of high-volume production process control simple and easy to understand. It lets you thoroughly understand process controls instead of blindly trusting software tools that operate as black boxes. If you are dealing with high-volume production as an operator, line supervisor, inspector, process engineer, quality engineer, manufacturing manager, plant manager, or president of the company, you have to understand the statistical process control basics explained in this book in order to be successful.

This book looks at how and where human resources (HR) meets quality management, and the implications of this. Most organizations, whatever their size or sector, struggle with demonstrating the value of continuous improvement (CI) and/or HR initiatives at a time when economic conditions are challenging in the global marketplace. Both within the UK and internationally, organizations will use continuous improvement and business excellence (BE) as a means of not only improving performance internally, but also to secure external recognition of their management practices, including people management, and therefore increase their competitiveness in their market. This text explores the potential overlaps between the two fields by considering how to address the development and implementation of a strategy to integrate CI/BE and human resource management. Practical and applied, this text provides: A brief overview of the concepts of CI and BE An analysis of the strategic factors impacting on an organization's decision-making around adopting a CI/BE approach, and the impact this may have on people management and development practices A review of some major external CI/BE accreditations and awards, and their value and how they might be used An analysis of the possible problems and outcomes which could be achieved by adopting such a CI/BE strategy and integrating it with people management and development activities This book is ideal for any professional HR or performance improvement practitioner who wants to understand how a CI/BE approach could benefit their organization, as well as postgraduate students of HR or quality management.

This book introduces students to business process management, an approach that aims to align the organization's business processes with the demands of the marketplace. Processes serve as a coordination mechanism, and the aim of business process management is to improve the organization's effectiveness and efficiency in adapting to change, and maintaining competitive advantage. In Business Process Management, Kumar argues for the value of looking at businesses as a collection of processes that cut across departments, and for breaking down functional silos. The book provides an overview of the basic concepts in this field before moving on to more advanced topics such as process verification, flexible processes, process security and evaluation, resource assignment, and social networks. One chapter of the book is also devoted to process analytics. The book concludes with an examination of the future directions of the discipline. Blending a strong grounding in current research with a focus on concepts and tools, Business Process Management is an accessible textbook full of practical examples and cases that will appeal to upper level students.

The Consulting Recommendation that All Your Employees will Agree on is Usually the One They Make. Traditional consulting often left the person key to an operations appraisal—the frontline worker—an afterthought. The outside consultant, trained to interview only those in key positions, would develop a corporate picture and plan for improvement that was inevitably judged irrelevant by those forced to implement it. Replacing the selective one-person interview with dynamic, all-inclusive group discussion, facilitative consulting made the forgotten worker a key contributor to the fact-finding process. Control Self-Assessment epitomizes the best of this approach to business process improvement. In this first comprehensive introduction to these methods, Control Self-Assessment explains how to successfully use CSA sessions to get a realistic look at the machinery and muscle of your firm—its day-to-day operations and staff—and develop a plan that will be enthusiastically put into practice. A chapter-by-chapter blueprint to setting up a CSA workshop, the book details everything from meeting mechanics, selecting the right time versus place model to creating the session agenda. Offering a practical profile of an ideal CSA facilitator, the book coaches consultants, auditors, and facilitators on the attitudes and skills needed (including when to use humor and how to manage difficult behavior) to keep a workshop dynamic, constructive, and in focus. It also describes how the core of CSA techniques can be adapted to assess and improve business risk as well as for use in sales seminars. Control Self-Assessment is a must for any firm in which CEOs and staff share a common vision built on their collective wisdom. "Traditional consulting is failing to meet client needs because it overlooks a key source of information: the client. Tritter’s facilitative techniques take consulting to the next level, detailing processes for sharing knowledge and gaining agreement. His focus on Control Self-Assessment gives the reader an excellent leverage point for improving business performance. With an emphasis on ‘how-to,’ this book gives practical techniques for assessing and managing business risk." —Tom Mcnamee, President, Sales Focus, Inc. Designer of Conexus^® Voting Hardware and Software "Control Self-Assessment: A Guide to Facilitation-Based Consulting provides a comprehensive guide to understanding the processes involved in CSA facilitation. Realistic problem-solving examples guide the novice facilitator through common facilitation pitfalls to enable the planning of a successful meeting. A good reference tool." —Lynda Sharpe-Lalonde President, Sharpe Decisions Inc.

Over the last 25 years there has been a considerable increase in the awareness of quality related issues. In the world of business and commerce, this awareness has manifested itself in the development of what was the British Quality Standard BS 5750 into what is now the international standard BS EN ISO 9000. Alongside all of this, consumers in general have developed increasingly demanding expectations with regard to the quality of goods and services available in the market place. During a similar period there has also been an increase in legislation, together with an expansion of the common law, which has strengthened the protection already afforded to the consumer. This book will provide quality practitioners, managers and those with a general interest in quality, with an insight into the legal issues involved. In addition, the book shows how the implementation of a Quality Assurance Management System - such as that required in order to be registered as a firm of assessed capability, in accordance with BS EN ISO 9000 - can act as an aid to businesses seeking to comply with their legal obligations.In addition, for those following a formal course of study, the contents will prove to be particularly useful to students undertaking the Institute of Quality Assurance's Associate Membership examination: Principles and Techniques of Quality Assurance.

In today's competitive world, customer demands for highly reliable products, makes reliability engineering a more challenging task.
