The procedures and results of a response time analysis study, which was designed to assess the value of police response to a variety of incidents, are summarized. The two primary objectives of this Kansas City, Missouri, study were: (1) analysis of the relationship of response time to the outcomes of on-scene criminal apprehension, witness availability, citizen satisfaction, and the frequency of citizen injuries in connection with crime and noncrime incidents; and (2) the identification of problems and patterns in reporting crime and requesting police assistance. The study design/data collection process continued over a 3-year period. Data were collected by civilian observers, communication tape analysis, and telephone and personal interviewers. Observers accompanied officers in the field to collect data on travel times and on-scene activities, while tape analysts collected dispatch times by timing verbal exchanges recorded on communications unit tape recordings. Victims of crimes and citizens who reported crime and noncrime incidents were interviewed to obtain reporting time data and to identify the problems encountered and patterns followed by those citizens reporting incidents or requesting police services. To analyze the relationships between response time and outcomes, three intervals in response times were considered: citizen reporting, communications dispatching, and police travel time. Variations in these intervals were then analyzed to see how they affected the probability of making an on-scene arrest and contacting a witness on scene, and how they affected recovery from injuries sustained during the commission of crimes. In addition, to see if the length of response time affected citizen satisfaction, police dispatch and travel times were again analyzed, along with other factors (such as citizens' social characteristics, expected response times, and perceptions of how long response took) considered to be possible determinants of citizens' satisfaction. Results indicated that reporting time was longer than either the time taken to dispatch a call or the time taken to travel to a call, and was nearly as long as the combined time taken to dispatch and travel to a call. For a large proportion of the crimes discovered some time after the incident had occurred, response time was found to be unrelated to the probability of making an arrest or locating a witness. For those crimes involving a victim or witness, reporting time was the strongest time determinant of arrest and witness availability. Citizen satisfaction was more closely related to citizens' expectations and perceptions about response time than to actual response time.

This practical book provides a step-by-step approach to testing mission-critical applications for scalability and performance before they're deployed -- a vital topic to which other books devote one chapter, if that. Businesses today live and die by network applications and web services. Because of the increasing complexity of these programs, and the pressure to deploy them quickly, many professionals don't take the time to ensure that they'll perform well and scale effectively. The Art of Application Performance Testing explains the complete life cycle of the testing process, and demonstrates best practices to help you plan, gain approval for, coordinate, and conduct performance tests on your applications. With this book, you'll learn to: Set realistic performance testing goals Implement an effective application performance testing strategy Interpret performance test results Cope with different application technologies and architectures Use automated performance testing tools Test traditional local applications, web-based applications, and web services (SOAs) Recognize and resolves issues that are often overlooked in performance tests Written by a consultant with 30 years of experience in the IT industry and over 12 years experience with performance testing, this easy-to-read book is illustrated with real-world examples and packed with practical advice. The Art of Application Performance Testing thoroughly explains the pitfalls of an inadequate testing strategy and offers you a robust, structured approach for ensuring that your applications perform well and scale effectively when the need arises. "Ian has maintained a vendor-agnostic methodology beautifully in this material. The metrics and graphs, along with background information provided in his case studies, eloquently convey to the reader, 'Methodology above all, tools at your discretion...' Ian's expertise shines through throughout the entire reading experience."-- Matt St. Onge, Enterprise Solution Architect, HCL Technologies America / Teradyne
