  • The goal of this book is to show how usability metrics can be a powerful tool for successfully evaluating the user experience for any product. When some people think about usability metrics, they feel overwhelmed by complicated formulas, contradictory research, and advanced statistical methods. We hope to demystify much of the research and focus on the practical application of usability metrics. We’ll walk you through a step-by-step approach to collecting, analyzing, and presenting usability metrics.

  • An operations manager uses job design techniques to structure work to meet the physical and behavioral needs of the employee. Work measurement methods are used to determine the most efficient means of performing a given task, as well as to set reasonable standards for performing it. Work performance standards are important to the workplace so accomplished can be measured and evaluated. Standards permit better planning and costing and provide a basis for compensating the work force and even providing incentives.

  • Many different metrics exist for evaluating parsing results, including Viterbi, Crossing Brackets Rate, Zero Crossing Brackets Rate, and several others. However, most parsing algorithms, including the Viterbi algorithm, attempt to optimize the same metric, namely the probability of getting the correct labelled tree. By choosing a parsing algorithm appropriate for the evaluation metric, better performance can be achieved.

  • CRM strategy (Customer Relationship Management) is a business philosophy, stemming from Relationship Marketing that joins strategy and technology, with the aim of creating value for both customers and the company. In this paper we justify the interest of establishing a formal system to measure CRM performance. In order to do that, we first focus on the role of marketing performance measurement throughout the time. Then, we compare different frameworks and metrics used to measure performance in the CRM era.

  • When a computer software succeeds—when it meets the needs of the people who use it, when it performs flawlessly over a long period of time, when it is easy to modify and even easier to use—it can and does change things for the better. But when software fails—when its users are dissatisfied, when it is error prone, when it is difficult to change and even harder to use—bad things can and do happen. We all want to build software that makes things better, avoiding the bad things that lurk in the shadow of failed efforts.

  • Simulation of Wireless Network Systems This chapter deals with simulation of wireless network systems. We introduce the basics of discrete-event simulation as it is the simulation technique that is used for simulating wireless networks. We then review the main characteristics of the commonly used stochastic distributions used for the simulation of wireless networks. The techniques used to generate and test random number sequences are investigated. Then, we introduce the techniques used to generate random variates followed by performance metrics considerations.

  • These results have implications for investors that integrate environmental and social data in their investment decision making process. Given recent evidence that investors across both buy-side (e.g., money managers, hedge funds, insurance companies, pension funds) and sell-side companies are paying attention to environmental and social performance metrics and disclosure (Eccles, Krzus, and Serafeim, 2011), evidence about the performance consequences of a culture of sustainability are particularly relevant. The remainder of the paper is as follows.

  • When failures occur, the fail over process moves processing performed by the failed component to the backup component. This process remasters systemwide resources, recovers partial or failed transactions, and restores the system to normal, preferably within a matter of microseconds. The more transparent that fail over is to users, the higher the availability of the system. Oracle has a number of products and features that provide high availability in cases of unplanned downtime or planned downtime.

  • There’s never been a more urgent time to implement marketing ROI processes. Companies are dependent on marketing organizations to win a greater share of profitable business in a very tight competitive market. At the same time, marketing expenses are under scrutiny, and it’s important to hold tight to the best investments while trimming only waste and low-performing investments. Most marketers do work toward the objective of generating profits even if other metrics are used to guide their decisions.
