ItemSuccessful delivery of flash track projects(Georgia Institute of Technology, 2016-04-14) Austin, Robert BrendonThis research explores a higher order of fast tracking, called Flash Tracking, in response to increasing calls for faster, more reliable project deliveries. Flash Tracking is defined as a time-driven project, which by necessity requires a heightened degree of concurrency between engineering, procurement, and construction. In contrast to fast tracking, which entails a level of concurrency between engineering, procurement, and construction that has become a staple of the construction industry, Flash Tracking extends the envelope by requiring a series of innovative practices across the project delivery spectrum. The specific research questions pursued include: 1) identifying which innovative improvements in project delivery methodology could be made to compress project durations, while maintaining safety, quality, and risk tolerance, and 2) addressing how project teams can best overcome barriers to delivering shorter project durations. A multi-method research project was undertaken to address these questions, which entailed an extensive review of the literature, structured case study interviews, and multiple group decision-making exercises. The literature review focused on the construction industry, as well as manufacturing, shipbuilding, and software development, to identify practices and techniques potentially relevant to Flash Tracking that could be extended to the construction industry. Group decision-making exercises included a modified Delphi method study, an Analytic Hierarchy Process, and a series of research charrettes or focus groups. These studies produced a prioritized, two-tiered listing of 47 essential Flash Track practices, providing practitioners with both a measure to assess their readiness for undertaking a Flash Track project and strategies for increasing their readiness. A subsequent study--a semantic network analysis--refined and buttressed the research team’s earlier findings. This two-year study, conducted in concert with industry experts, led to a re-engineered engineering, procurement, and construction (EPC) model which embraces relational contract strategies, improved communications, and the early engagement of key stakeholders.

ItemEvaluating supplier diversity development programs (SDDP) from the diverse supplier enterprise (DSE) perspective in the facility management industry(Georgia Institute of Technology, 2016-04-04) Hatcher, Michael B.Supplier diversity refers to the practice of creating opportunities for historically underutilized populations in the workforce and business arena. Supplier diversity encompasses initiatives specifically designed to increase the number of enterprises owned by people from ethnic minority groups who supply public, private, and/or voluntary sector organizations with goods and services (Ram & Smallbone, 2003). Supplier diversity initiatives were once driven solely by governmental policies focused on ethnic minorities. Also, minority vendor purchasing programs were designed to increase the volume of goods and services purchased by corporations from minority-owned businesses (Giunipero, 1981). Guided by the existing literature related to supplier diversity, this qualitative phenomenological study investigated the current state of Supplier Diversity Development Programs (SDDP) from the diverse supplier perspective. Primarily this research illuminated the (1) lived experiences of DSE Supplier Diversity Development Program participants (2) investigated the extent to which SDDPs eliminate or mitigate barriers/impediments to diverse suppliers previously identified in academic literature, and (3) evaluated the impact of SDDP participation on DSE business capacity development. This study explored and evaluated Supplier Diversity Development Programs to serve as a guide for (a) public and private POs in the facility management industry that currently utilize some supplier diversity development programs and (b) organizations seeking to implement SDDPs in the future. This research identified and posited a series of recommendations for the improvement of existing programs and the creation of new Supplier Diversity Development Programs. This research found that a Supplier Diversity Development Program that aligns program expectation with program delivery will result in greater levels of positive program participation outcomes. In addition this research study found SDDP mitigates DSE barriers/impediments and impacts DSE business capacity development, by way of building relationships, administering education, raising awareness, and creating platforms for access and engagement.

ItemEvaluating the impacts of enterprise resource planning on organizational performance for small to medium enterprises in manufacturing(Georgia Institute of Technology, 2015-04-02) Sedehi, AryaToday’s fast-paced global economy has intensified the demand for manufacturing companies to make their products more quickly and with higher quality to meet heightened consumer expectations while reducing costs. This competitive environment requires small to medium enterprise’s (SMEs) to implement well-designed business processes and leverage information technology (IT), such as an Enterprise Resource Planning (ERP) system, within their facilities to become more agile, flexible, and integrated to meet changing market demands. Issues emerge when facility managers lack reliable data on performance and costs, which subsequently impairs even basic decisions for resource allocation or process improvement. Although the benefits of a successful ERP implementation in large firms are recognized, there is a general lack of empirical IT productivity literature focusing on SMEs. This research is expected to contribute to a framework for performance measurement, providing facility decision-makers with important metrics for analyzing their firm’s ability to improve upon competitive priorities. Employing the Delphi process, key performance indicators (KPIs) including time, speed, quality, and cost, and corresponding performance measurement metrics, investigations are conducted between traditional manufacturing processes in SMEs and processes enhanced through ERP adoption. In this longitudinal case study, significant improvements are observed in production operations relative to time following ERP implementation including a reduction in the defect rate, total manufacturing cost, and scrap rate along with increases in on-time delivery and flexibility.

ItemAn evaluation of home hospital care impacts on emergency department boarding using simulation(Georgia Institute of Technology, 2015-01-06) Fard, JohnThe hospital emergency department (ED) is a critical source for health care amid a complex healthcare system in the United States. It is the gateway to care for a broad range of people, arriving from a variety of locations. With this wide reaching net and a decreasing trend in hospital beds, EDs throughout the United States are experiencing overcrowding. ED crowding has various tactical and strategic facility management impacts ranging from facility occupancy issues to adverse health outcomes. Among other factors, recent research has cited the sharp increase in ED visits over the years and ED patient boarding as key contributors to crowding. Home hospital care is a model in which health care is delivered at an individual’s home as a substitute for hospital-level inpatient short-term acute care. Clinical research has shown home hospital to be an effective care model for select illnesses presenting frequently to EDs, such as congestive heart failure, community acquired pneumonia, chronic obstructive pulmonary disease, and cellulitis. While there exist distinct clinical and social criteria for which delineate eligible individuals, home hospital care models have been linked with the potential to free inpatient beds. The overarching objective of this study is to investigate the relationship between home hospital care and ED crowding. To achieve this objective, the study examined the relationship between home hospital care and ED crowding, specific to ED boarding performance at a large, urban, teaching hospital facility. A methodology for identification of potential home hospital patients was used through clinical and social criteria, and a scale for the range of clinical eligibility rates was established for the five suitable illnesses. The study modeled patient flow and bed demand, and utilized computer simulation modeling to assess the impact of home hospital care on ED boarding performance. Various models were simulated to represent different home hospital intervention types. The models incorporated home hospital through an ED Referral program, Inpatient-Transfer Referral program, Community Referral program, and a fully integrated home hospital program. Three scenarios were run for each model to assess practical possibilities for the utilization of the freed bed hours from a home hospital program. This research contributes insight and understanding of home hospital’s impacts on ED crowding. The insight from this study quantifies the effects of a home hospital program on ED boarding and inpatient bed demand. The modeling study is contributes an analytical understanding of the impacts that home hospital could potentially have on crowding, which could prove useful in the struggle against ED congestion. This understanding helps to provide a more thorough understanding of home hospital, and could aid in an organization’s decision-making process of whether to implement a program. The presented modeling methodology for analyzing home hospital and ED crowding can also be used as a model format for researchers and practitioners for analytical purposes in future studies.
