Book Description
Statistical methods are a key part of of data science, yet very few data scientists have any formal statistics training. Courses and books on basic statistics rarely cover the topic from a data science perspective. This practical guide explains how to apply various statistical methods to data science, tells you how to avoid their misuse, and gives you advice on what's important and what's not. Many data science resources incorporate statistical methods but lack a deeper statistical perspective. If you’re familiar with the R programming language, and have some exposure to statistics, this quick reference bridges the gap in an accessible, readable format. With this book, you’ll learn: Why exploratory data analysis is a key preliminary step in data science How random sampling can reduce bias and yield a higher quality dataset, even with big data How the principles of experimental design yield definitive answers to questions How to use regression to estimate outcomes and detect anomalies Key classification techniques for predicting which categories a record belongs to Statistical machine learning methods that “learn” from data Unsupervised learning methods for extracting meaning from unlabeled data

Book Description
In this pathbreaking book, world-renowned Harvard Business School service firm experts James L. Heskett, W. Earl Sasser, Jr. and Leonard A. Schlesinger reveal that leading companies stay on top by managing the service profit chain. Why are a select few service firms better at what they do -- year in and year out -- than their competitors? For most senior managers, the profusion of anecdotal "service excellence" books fails to address this key question. Based on five years of painstaking research, the authors show how managers at American Express, Southwest Airlines, Banc One, Waste Management, USAA, MBNA, Intuit, British Airways, Taco Bell, Fairfield Inns, Ritz-Carlton Hotel, and the Merry Maids subsidiary of ServiceMaster employ a quantifiable set of relationships that directly links profit and growth to not only customer loyalty and satisfaction, but to employee loyalty, satisfaction, and productivity. The strongest relationships the authors discovered are those between (1) profit and customer loyalty; (2) employee loyalty and customer loyalty; and (3) employee satisfaction and customer satisfaction. Moreover, these relationships are mutually reinforcing; that is, satisfied customers contribute to employee satisfaction and vice versa. Here, finally, is the foundation for a powerful strategic service vision, a model on which any manager can build more focused operations and marketing capabilities. For example, the authors demonstrate how, in Banc One's operating divisions, a direct relationship between customer loyalty measured by the "depth" of a relationship, the number of banking services a customer utilizes, and profitability led the bank to encourage existing customers to further extend the bank services they use. Taco Bell has found that their stores in the top quadrant of customer satisfaction ratings outperform their other stores on all measures. At American Express Travel Services, offices that ticket quickly and accurately are more profitable than those which don't. With hundreds of examples like these, the authors show how to manage the customer-employee "satisfaction mirror" and the customer value equation to achieve a "customer's eye view" of goods and services. They describe how companies in any service industry can (1) measure service profit chain relationships across operating units; (2) communicate the resulting self-appraisal; (3) develop a "balanced scorecard" of performance; (4) develop a recognitions and rewards system tied to established measures; (5) communicate results company-wide; (6) develop an internal "best practice" information exchange; and (7) improve overall service profit chain performance. What difference can service profit chain management make? A lot. Between 1986 and 1995, the common stock prices of the companies studied by the authors increased 147%, nearly twice as fast as the price of the stocks of their closest competitors. The proven success and high-yielding results from these high-achieving companies will make The Service Profit Chain required reading for senior, division, and business unit managers in all service companies, as well as for students of service management.

Book Description
Every company has a personality. Does yours help or hinder your results? Does it make you fit for growth? Find out by taking the quiz that’s helped 50,000 people better understand their organizations at OrgDNA.com and to learn more about Organizational DNA. Just as you can understand an individual’s personality, so too can you understand a company’s type—what makes it tick, what’s good and bad about it. Results explains why some organizations bob and weave and roll with the punches to consistently deliver on commitments and produce great results, while others can’t leave their corner of the ring without tripping on their own shoelaces. Gary Neilson and Bruce Pasternack help you identify which of the seven company types you work for—and how to keep what’s good and fix what’s wrong. You’ll feel the shock of recognition (“That’s me, that’s my company”) as you find out whether your organization is: • Passive-Aggressive (“everyone agrees, smiles, and nods, but nothing changes”): entrenched underground resistance makes getting anything done like trying to nail Jell-O to the wall • Fits-and-Starts (“let 1,000 flowers bloom”): filled with smart people pulling in different directions • Outgrown (“the good old days meet a brave new world”): reacts slowly to market developments, since it’s too hard to run new ideas up the flagpole • Overmanaged (“we’re from corporate and we’re here to help”): more reporting than working, as managers check on their subordinates’ work so they can in turn report to their bosses • Just-in-Time (“succeeding, but by the skin of our teeth”): can turn on a dime and create real breakthroughs but also tends to burn out its best and brightest • Military Precision (“flying in formation”): executes brilliant strategies but usually does not deal well with events not in the playbook • Resilient (“as good as it gets”): flexible, forward-looking, and fun; bounces back when it hits a bump in the road and never, ever rests on its laurels For anyone who’s ever said, “Wow, that’s a great idea, but it’ll never happen here” or “Whew, we pulled it off again, but I’m tired of all this sprinting,” Results provides robust, practical ideas for becoming and remaining a resilient business. Also available as an eBook From the Hardcover edition.

Book Description
Over the past ten years there has been a massive growth in call centres worldwide. These centres are said to represent the most dynamic growth area in white-collar employment internationally since the mid 1990s. Yet the footloose and global nature of the industry means that jobs will always be susceptible to outsourced operations, ICT developments, public sector subsidization of business restructuring and re-location, and cheaper operations elsewhere. This book conducts a thorough analysis of this modern phenomenon.

Annotation With the emergence of the callcenter as a mission-critical part of the corporate customer service strategy, management of the callcenter has moved from a reactive "fire-fighting" style to a more proactive tactical style of professional management. Measurements drive behavior, and "you get what you measure and reward." The primary purpose of this book is to provide new professional callcenter managers with a methodology for "managing their callcenter by the numbers."
