Modeling for Insight


Book Description

Praise for Modeling for Insight "Most books on modeling are either too theoretical or too focused on the mechanics of programming. Powell and Batt's emphasis on using simple spreadsheet models to gain business insight (which is, after all, the name of the game) is what makes this book stand head and shoulders above the rest. This clear and practical book deserves a place on the shelf of every business analyst." —Jonathan Koomey, PhD, Lawrence Berkeley National Laboratory and Stanford University, author of Turning Numbers into Knowledge: Mastering the Art of Problem Solving Most business analysts are familiar with using spreadsheets to organize data and build routine models. However, analysts often struggle when faced with examining new and ill-structured problems. Modeling for Insight is a one-of-a-kind guide to building effective spreadsheet models and using them to generate insights. With its hands-on approach, this book provides readers with an effective modeling process and specific modeling tools to become a master modeler. The authors provide a structured approach to problem-solving using four main steps: frame the problem, diagram the problem, build a model, and generate insights. Extensive examples, graduated in difficulty, help readers to internalize this modeling process, while also demonstrating the application of important modeling tools, including: Influence diagrams Spreadsheet engineering Parameterization Sensitivity analysis Strategy analysis Iterative modeling The real-world examples found in the book are drawn from a wide range of fields such as financial planning, insurance, pharmaceuticals, advertising, and manufacturing. Each chapter concludes with a discussion on how to use the insights drawn from these models to create an effective business presentation. Microsoft Office Excel and PowerPoint are used throughout the book, along with the add-ins Premium Solver, Crystal Ball, and Sensitivity Toolkit. Detailed appendices guide readers through the use of these software packages, and the spreadsheet models discussed in the book are available to download via the book's related Web site. Modeling for Insight is an ideal book for courses in engineering, operations research, and management science at the upper-undergraduate and graduate levels. It is also a valuable resource for consultants and business analysts who often use spreadsheets to better understand complex problems.




The Design of Insight


Book Description

Familiar modes of problem solving may be efficient, but they often prevent us from discovering innovative solutions to more complex problems. To create meaningful change, we must train ourselves to discover previously unseen variables in day-to-day challenges. The Design of Insight is intended to be a personal problem-solving platform for decision makers and advisors who seek answers to critical business questions. It introduces an approach that uses multiple "problem-solving languages" to systematically expand our understanding of problem framing and high quality problem solving. Useful as a critical thinking approach or a think-out-loud document for strategic teams, this brief is a resource for enriching and implementing thoughtful management practices.

Seeing What Others Don't


Book Description

Insights -- like Darwin's understanding of the way evolution actually works, and Watson and Crick's breakthrough discoveries about the structure of DNA -- can change the world. We also need insights into the everyday things that frustrate and confuse us so that we can more effectively solve problems and get things done. Yet we know very little about when, why, or how insights are formed -- or what blocks them. In Seeing What Others Don't, renowned cognitive psychologist Gary Klein unravels the mystery. Klein is a keen observer of people in their natural settings -- scientists, businesspeople, firefighters, police officers, soldiers, family members, friends, himself -- and uses a marvelous variety of stories to illuminate his research into what insights are and how they happen. What, for example, enabled Harry Markopolos to put the finger on Bernie Madoff? How did Dr. Michael Gottlieb make the connections between different patients that allowed him to publish the first announcement of the AIDS epidemic? What did Admiral Yamamoto see (and what did the Americans miss) in a 1940 British attack on the Italian fleet that enabled him to develop the strategy of attack at Pearl Harbor? How did a "smokejumper" see that setting another fire would save his life, while those who ignored his insight perished? How did Martin Chalfie come up with a million-dollar idea (and a Nobel Prize) for a natural flashlight that enabled researchers to look inside living organisms to watch biological processes in action? Klein also dissects impediments to insight, such as when organizations claim to value employee creativity and to encourage breakthroughs but in reality block disruptive ideas and prioritize avoidance of mistakes. Or when information technology systems are "dumb by design" and block potential discoveries. Both scientifically sophisticated and fun to read, Seeing What Others Don't shows that insight is not just a "eureka!" moment but a whole new way of understanding.

Occupancy Estimation and Modeling


Book Description

Occupancy Estimation and Modeling: Inferring Patterns and Dynamics of Species Occurrence, Second Edition, provides a synthesis of model-based approaches for analyzing presence-absence data, allowing for imperfect detection. Beginning from the relatively simple case of estimating the proportion of area or sampling units occupied at the time of surveying, the authors describe a wide variety of extensions that have been developed since the early 2000s. This provides an improved insight about species and community ecology, including, detection heterogeneity; correlated detections; spatial autocorrelation; multiple states or classes of occupancy; changes in occupancy over time; species co-occurrence; community-level modeling, and more. Occupancy Estimation and Modeling: Inferring Patterns and Dynamics of Species Occurrence, Second Edition has been greatly expanded and detail is provided regarding the estimation methods and examples of their application are given. Important study design recommendations are also covered to give a well rounded view of modeling. - Provides authoritative insights into the latest in occupancy modeling - Examines the latest methods in analyzing detection/no detection data surveys - Addresses critical issues of imperfect detectability and its effects on species occurrence estimation - Discusses important study design considerations such as defining sample units, sample size determination and optimal effort allocation




Insight Selling


Book Description

What do winners of major sales do differently than the sellers who almost won, but ultimately came in second place? Mike Schultz and John Doerr, bestselling authors and world-renowned sales experts, set out to find the answer. They studied more than 700 business-to-business purchases made by buyers who represented a total of $3.1 billion in annual purchasing power. When they compared the winners to the second-place finishers, they found surprising results. Not only do sales winners sell differently, they sell radically differently, than the second-place finishers. In recent years, buyers have increasingly seen products and services as replaceable. You might think this would mean that the sale goes to the lowest bidder. Not true! A new breed of seller—the insight seller—is winning the sale with strong prices and margins even in the face of increasing competition and commoditization. In Insight Selling, Schultz and Doerr share the surprising results of their research on what sales winners do differently, and outline exactly what you need to do to transform yourself and your team into insight sellers. They introduce a simple three-level model based on what buyers say tip the scales in favor of the winners: Level 1 "Connect." Winners connect the dots between customer needs and company solutions, while also connecting with buyers as people. Level 2 "Convince." Winners convince buyers that they can achieve maximum return, that the risks are acceptable, and that the seller is the best choice among all options. Level 3 "Collaborate." Winners collaborate with buyers by bringing new ideas to the table, delivering new ideas and insights, and working with buyers as a team. They also found that much of the popular and current advice given to sellers can damage sales results. Insight Selling is both a strategic and tactical guide that will separate the good advice from the bad, and teach you how to put the three levels of selling to work to inspire buyers, influence their agendas, and maximize value. If you want to find yourself and your team in the winner's circle more often, this book is a must-read.

Insight


Book Description

Research on insight problem solving examines how new ideas are generated to solve problems that initially resist the application of prior knowledge or analogue solutions. In the laboratory, insight problems are designed to create an impasse; overcoming the impasse is sometimes accompanied by a distinctive phenomenological experience, the so-called Aha! moment. Insight: On the Origins of New Ideas presents research that captures these episodes of insight under laboratory conditions and informs models that account for their emergence. Descriptions and analyses of episodes of discovery both in and out of the laboratory are included to provide a general overview of insight. Featuring contributions from leading researchers, the volume debates the relative importance of intelligence and working memory, the development of an alternative interpretation of the problem based on deliberate analyses and heuristics, and unconscious inferences in the emergence of insight. These discussions generate new testable hypotheses to shed light on the cognitive processes underpinning insight, along with concrete methodological recommendations that, together, map a productive programme of future research. This book will be of interest to students and researchers of thinking and reasoning - specifically those interested in insight and creative problem solving.
