Introduction

Project Management is the process of planning, organizing, monitoring and adjusting a project's direction (Tsui). A 2001 report showed that the US spends 2.3 trillion dollars on projects every year, an amount equal to 25% of the nation's gross domestic product (PMI). The failure to successfully complete major software projects have even proved fatal to their sponsoring organizations including, American LaFrance and FoxMeyer Drugs.

Standish Report

The Standish Group International, Inc. is a research advisory firm founded in 1989 and headquartered in Massachusetts (Standish, 1994). The Standish Group is best known for a series of reports on failures in the software development industry. The first of these reports, released in 1994, asserted that the software development industry is in a state of chaos. The report found that 31% of the projects that respondents undertook were cancelled before completion. Moreover, 52% of projects cost 189% of their original estimated budgets (Standish, 1994). The 1994 report discusses presents a series of case studies including a software project failure in the Denver airport baggage claim that cost taxpayers 1.1 million dollars per day (Standish, 1994). This report estimated that in 1995 over 81 billion dollars will be spent on cancelled software projects in the United States (Standish, 1994).

Trilogy

From September 2000 to April 2005, The Federal Bureau of Investigation (FBI) spent over 100 million dollars on a software system that has since been discarded. This system, alternately known as the Virtual Case File (VCF) system and Trilogy, was intended as a response to the 9/11 commission's obaservation that the FBI had failed to correlate data that may have helped prevent the 9/11 hijacking. Quantitative Analysis Methods 4 The FBI's current system, Automated Case Support (ACS), is a command line driven application that is supported by an antiquated German database. Its interface was deemed unusable by many FBI agents (Goldstein). In the face of intense public and congressional pressure, the project manager made an extremely poor decision to move the deadline to December 2003 from June 2004 (Goldstein). In March 2004 an arbitrator found 59 key problems with the project, including 40 key development errors by SAIC and 19 changes in system requirements by the FBI (Goldstein). Various reasons have been given for the project's failure. Direct results of this root cause were the many missteps along Trilogy's development path. The four basic project management activity sets—planning, organizing, monitoring and adjusting—were not followed (Tsui). Management's incompetence was rampant, and the FBI failed to establish controls and maintain accountability throughout the Trilogy project.

Descriptive Statistices and Tablure

 

Once the privilege graph (or the intrusion process) is constructed, computation of the quantitative assesses is done. In the context of our demonstration, the target of this computation is to display that the entire quantitative evaluation procedure can be directed effectively to an organization. These outcomes permit us to study the procedure of the association and to contrast likely ...
