"ROOT CAUSE ANALYSIS or RCA, What is it? Everyone uses the term, but everyone does it differently. Given that, how can we have any uniformity in our approach much less accurately compare our results? At a high level, we will explain the difference between a Root Cause Analysis and a Shallow Cause Analysis, because that is the difference between allowing a failure to recur or dramatically reducing the risk of recurrence. In this book we will get down to basics about 'RCA', the fundamentals of blocking and tackling, and explain the common steps of any investigative occupation. Those common investigation steps include : Preserving evidence (data)/not allowing hearsay to fly as fact Organizing an appropriate team/minimizing potential bias. Analyzing the events/reconstructing the incident based on actual evidence. Communicating findings and recommendations/ensuring effective recommendations are actually developed and implemented. Tracking bottom-line results/ensuring that identified, meaningful metrics were attained. We explore why don't things always go as planned. When our actual plans deviate from our intended plans, we usually experience some type of undesirable or unintended outcome. We analyze the anatomy of a failure (undesirable outcome) and provide a step-by-step guide to conducting a comprehensive root cause analysis based on our 3+ decades of applying RCA as we have successfully practiced it in the field. The book is written as a "how-to" guide to effectively apply the PROACT RCA Methodology to any undesirable outcome, is directed at practitioners who have to do the real work, focuses on the core elements of any investigation, and provides a field-proven case as a model for effective application. This book is for anyone charged with having a thorough understanding of why something went wrong, such as those in EH&S, maintenance, reliability, quality, engineering, and operations to name just a few"--

This book introduces the '5 Whys' method, a problem-solving technique developed by Sakichi Toyoda, founder of Toyota Industries. The method involves asking 'Why?' multiple times to uncover the root cause of a problem rather than merely addressing symptoms. Widely used in various sectors including manufacturing, logistics, and quality management, the technique helps organizations and individuals efficiently identify fundamental issues and develop effective, long-lasting solutions. The book provides practical steps on implementing the 5 Whys method, emphasizing its simplicity, cost-effectiveness, and its ability to enhance team collaboration and creativity. However, it also highlights limitations such as potential biases and the need for expertise in questioning. The intended audience includes business professionals, project managers, and anyone interested in improving problem-solving skills.

Giardiasis is one of the most common gastrointestinal parasitic diseases worldwide and it is caused by an enteric pathogen named Giardia spp. Giardiasis is the most commonly reported human parasite of gastroenteritis with frequent sporadic cases and community-wide outbreaks via water- and -in smaller proportion- foodborne pathways. Giardiasis encompasses a complex and diverse spectrum of symptom patterns ranging from asymptomatic carriage to acute and chronic health states. Prolonged chronic infections eau enhance extra-intestinal and post-infectious sequelae. Estimation of the population health status, also known as "disease burden", requires well-defined information on clinical outcomes of infection. Unfortunately, regarding the diverse symptomatology and limited knowledge on pathogenesis mechanisms, giardiasis burden is often difficult to estimate and report. Objectives: To accurately estimate the disease burden of giardiasis and explain satisfactory its clinical impact, it is therefore necessary to have information on the nature and frequency of these sequelae. To this end, we aim to be able to get a better understanding of the symptoms of Giardia infection in humans. The aim of this thesis will be to review the clinical impact of giardiasis worldwide using a systematic search approach. To this end we will proceed in a two-step approach as follows: 1.First we will review existing assessments of the disease burden of Giardia. This will give an overview of the current disease models (i.e., lists of giardiasis symptoms .2.Next we will perform a systematic review of clinical symptoms associated with Giardia infection in humans in order to identify the health states which are associated with the giardiasis burden and estimate the occurrence of potential sequelae (acute and chronic) of giardiasis. Methods: In order to address the identified gaps, we chose to perform systematic review of the literature according to PRISMA guidelines. We will focus on prospective studies (i.e., cohort studies, longitudinal studies and outbreak investigations) retrospective studies (i.e., case-control studies) and cross-sectional studies. Findings: To date, we have irrefutable evidence of variability in clinical outcomes associated with Giardia infection. Typically assumed as a re-emerging and neglected disease, giardiasis places a heavy burden in both developed and developing countries. It has been linked to persistent diarrhoea that may contribute to substantial weight loss, retardation of growth and development in infants, cognitive impairment and malabsorption. In addition, it has been confirmed that acute giardiasis is associated with significant post-infectious chronic sequelae in adults such as imitable bowel syndrome, chronic fatigue or functional dyspepsia. These persistent sequelae affect the quality of life by continuing to inflict on patients long lasting discomfort and pain.

In this book, we introduce an automatic, experiment-based approach for performance problem diagnostics in enterprise software systems. The proposed approach systematically searches for root causes of detected performance problems by executing series of systematic performance tests. The presented approach is evaluated by various case studies showing that the presented approach is applicable to a wide range of contexts.
