- Description:
- In the last 20 years, wood items and the furniture industry in the United States have been influenced by the competitive business environment, unpredictable economic cycles, increased production levels and transportation expenditure, changing purchaser propensities, and expanded international competition. Due to these reasons the smallscale manufacturers have been compelled to implement Lean in order to optimize productivity while at the same time reduce waste. This thesis tries to expand on the difficulties and obstacles confronted while applying Lean concepts in job shop environment. The research relied on scientific literature to explain the main principles of Lean. On the basis of information collected, a number of challenges were recognized and recommendations on how to resolve them were presented. The outcomes of this study are expected to offer strategic and value addition to the small manufacturers on the use of Lean manufacturing with value stream mapping.

- This thesis examines the archetypal heroic journey of Harper Lee’s protagonist Jean Louise “Scout” Finch from childhood to her adult years through two of the author’s works. The study is presented with chapters focusing on three main categories of Campbell’s and Murdock’s works on heroic journeys: the separation, the initiation, and the return. Each chapter presents an analysis of the characters, the author, and the social and familial constraints that illustrate and impact the protagonist’s journey. In comparing two fictional stories dramatizing the heroic coming-of-age quest of a female character, it can be argued that women may travel different paths as they age on their solitary journeys toward self-awareness. As a child, a girl like Scout may travel the path of Campbell’s hero. As she matures and encounters challenges from social and familial constraints and expectations, she begins to travel the path of Murdock’s heroine.

- Description:
- The focus of this study is two-fold: (1) an exploratory literature review of Lean thinking implementation and (2) a directed Lean Thinking implementation project, specifically 5S, applied to a cosmeceutical manufacturing environment. The objective of the project, coupled with literature reviews, was to determine whether a 5S implementation project can impact eliminating wastes while improving efficiency. Qualitative measurements are observed and recorded from an empirical lens, via a 5S Assessment Checklist. The uniqueness of this project is that 5S Lean thinking has not been well documented or implemented in the cosmeceutical manufacturing environment. The completion and analysis of the 5S project data suggests that Seiri, Seiton, and Seiso are fairly easy to adopt, whereas Seiketsu and Shitsuke are the hardest—particularly Shitsuke. The data from this thesis suggest that 5S principles qualitatively contribute to minimizing wastes, thereby increasing productivity and improving quality for the organization in the cosmeceutical manufacturing environment

- Errors in laboratories are a common phenomenon. The hematology/oncology physicians primarily rely on results of samples taken to laboratories in order to make comprehensive inferences and diagnoses of the patients’ conditions. Therefore, the analysis of errors therein is impartial, as it is the only way through which the prevalence can be addressed making diagnosis more credible. This research involved the analysis of five laboratories, each of which participated for a period of one year, and recorded the incidences of pre-analytical errors. According to the data obtained, inadequate sample errors are the most prevalent at 61%, test order entry errors, followed at 37% with labeling and missing patient identities being reported as the least prevalent errors at 1%. Through this study, the reasons why the errors occurred have been identified and the resulting corrective measures discussed. Therefore, this study is monumental in the hematology/oncology laboratories as with remedies comes more perfection.

- Description:
- Lean is a process that drives improvement in manufacturing facilities. With Lean’s focus on customer needs and continuous improvement, companies have used Lean tools and techniques to improve products and decrease manufacturing costs. Application to a specific office process, product risk management, is explored in this paper. Most medical device regulatory agencies around the world require risk management. Compliance theoretically results in medical devices designed and manufactured in a manner resulting in safe and effective devices. Standards contain descriptions of tools used to analyze hazards and describe how to associate risk levels with these hazards. This paper presents the use of Lean tools and methodology to simplify the risk management process, making it understandable and compliance easy. Case studies of similar administrative projects are reviewed, and lessons learned are applied to this project. Additionally, risk management systems at three medical device manufacturers are evaluated, using Lean techniques.

- Description:
- Policy-Driven Data Centers (PDDCs) are data centers in which all Virtual Machine (VM) traffic must traverse a sequence of Middleboxes (MBs). These MB policies help guarantee a given level of security and performance for all applications hosted in the PDDC at the cost of increased network traffic and energy consumption. This thesis proposes a new VM optimization framework called VM2P (Virtual-Machine Migration in PDDCs), which, when given an existing PDDC with existing VM placements and policies, will migrate VMs within a PDDC in order to minimize energy consumption while still maintaining all policy constraints. This thesis will also show how the VM placement problem VMP2 (Virtual-Machine Placement in PDDCs), the problem of distributing VMs into an empty PDDC such that energy consumption is minimized, is actually a special case of VM2P. The performance of VM2P and VMP2 are evaluated via simulations wherein the algorithms will compete with state-of-the-art policy-agnostic algorithms.

- Description:
- Numerous deficiencies associated with the U.S. Navy’s supplier cost overruns, schedule delays, and reporting methods have been identified by the Government Accountability Office (GAO) during the last decade. This study adapted the Balanced Scorecard (BSC) to a customer-supplier scenario and then used it to provide the U.S. Navy a supplier assessment tool to utilize on their shipbuilders to addresses those deficiencies. The Naval Surface Force Strategy (2017) was used to extract objectives that furnished the strategy map’s perspective. The Supplier-Input-Process-Output-Customer (SIPOC) tool was a complementary asset utilized to identify the relevant measures in the product development cycle. The final product for this study is a 19-metric measuring system that addresses the GAO’s U.S. Navy supplier management concerns and a unique adaptation of the BSC for a contractor-supplier scenario.

- Improving the quality of healthcare has become a priority in order to make healthcare safer, more effective, and cost-controlling. The Center for Medicare and Medicaid Services (CMS) has been addressing the high hospital readmission rates with new regulations that encourage hospitals to improve the quality of care provided. Heart failure is the most common reason behind hospital readmissions in the United States. Studies have shown that patient education is a crucial part of the healthcare process that can affect the quality of care and readmission rate. The purpose of this thesis is to design a new hospital based multidisciplinary heart failure educational process using the Six Sigma methodology, Define, Measure, Analyze, Design, Verify (DMADV). It focuses on achieving a sustainable process with emphasis on standardization and team approach as well as monitoring performance improvement with the goal to meet and exceed the CMS benchmark.

- Poor quality medical devices may lead to dire financial and reputational consequences for an organization. Food and Drug Administration (FDA) warning letters are indicators of the challenges the medical device industry has to overcome the deficiencies. Process validation is a crucial element of the quality system within the medical device industry. When considering the number of FDA process validation issues which were uncovered between 2014 to 2018, the percentage of violations decreased significantly from 90.77 to 85.29%. However, procedural violations accounted for 100% of warning letters drafted during or before September 2018. Addressing issues at the design and process validation phase could greatly improve overall quality assurance, and potentially lead to fewer recalls, FDA warning letters, manufacturing issues, and related financial and/or reputational risks for the medical device industry.

- In today’s fiercely competitive society, the most valuable way of securing a competitive advantage and improving organizational performance is through quality improvement. XYZ is an organization which provides chemicals used to create nextgeneration chemical-mechanical planarization (CMP) slurries. This study used a mixedmethods explanatory, sequential design, in combination with quality tools, to identify and comprehend the reasons for XYZ’s poor leak test on stainless steel containers used to transport chemicals. Approximately 50% of Company XYZ’s stainless steel containers for chemical storage passed the leak test when a pass rate of 90% or higher is desired, creating practical problems for the company and its customers. This study aimed to explore and comprehend the reasons for the poor leak test results with the application of Deming’s Plan, Do, Check, Action (PDCA) cycle. The use of quality tools and statistical analyses indicate that marrying lids and bases of containers increases leak test pass rates.
