A key process in the oil industry to make decisions is data collection. To improve productivity it is important data and information analysis. For many organizations is not profitable data automation, which has an impact in the way organizations, collect data. Data collection is taken by manual processes that create uncertainty for analysis because it is not reliable. As consequence, making a decision has not the planned results. After working for many years in the oil industry was identified: 1. People collecting data in a manual process normally by using a piece of paper which could be lost or damage. 2. After taking data at the well, data are brought to the office. Then, data are downloaded by another worker in computer software. It can be modified intentionally or not. 3. Accuracy of data collection activity is carried out. How do we know if the staff really went to work area? 4. Training to new staff, lack of experience? 5. There are “risks zones” due vandalism, facilities are damaged by people who stole devices which causes great money losses to companies. All these mentioned factors affect decision making which has a big impact in the production process. This application helps the whole process from collection data until data are registered in databases. This application considered several observations, suggestions and comments from people involve in the oil industry, especially at the production area. As a result, it is a tool that support data collection, standardize information in databases, improve data quality (it doesn’t matter localization), shows time and photographic position in a mobile device. Information is generated digitally taking advantage of easy handling. To summarize advantages of the whole system: • Reduce time of the data re-collection process • Improve data quality • Reduce amount of people working on data registration • Data reliability • Support decisions making • Minimize the use of paper in order to help ambient environment • Improve vehicle logistics • Minimize use of gasoline which helps to reduce costs • Help to optimize routes for vehicles on the field • Productivity, Maintenance, etc., reports can be generated • Vandalism is not a problem

<p class="abstract"><strong>Background:</strong> In migraine clinical trials, patients’ understanding of the terminology used in patient-reported outcome (PRO) measures is important as variability in completing PRO measures can reduce the power to detect treatment efficacy. This study examines patients’ understanding of how to complete PRO measures in the absence of training, if minimal training can improve the accuracy of answering PRO items, and patients’ opinion on the necessity of training and their preference for the method of training.</p><p class="abstract"><strong>Methods:</strong> Participants reporting a diagnosis of migraine completed online surveys. Participants were given scenarios of how to report headache days and pain severity. Respondents were asked about their opinions on the necessity of training, and their preference for the method of training. In a second study, participants were given a hypothetical scenario on how to report pain severity before and after a short training.</p><p class="abstract"><strong>Results:</strong> The majority of participants had different criteria to interpret PRO questions and provided incorrect answers to our scenarios. In the second study, with minimal training, errors were reduced by 7.5%. Over 90% of participants viewed educational materials and training as necessary and preferred electronic modes of training with the ability to review training materials as needed for the duration of the trial.</p><p class="abstract"><strong>Conclusions: </strong>Patient training may improve data quality and inter-rater reliability in clinical trials. Electronic interactive training could be used as an approach to reduce inconsistencies in PRO measures and improve data quality.</p>

Assess Data Quality

RNA interference (RNAi) not only plays an important role in drug discovery but can also be developed directly into drugs. RNAi high-throughput screening (HTS) biotechnology allows us to conduct genome-wide RNAi research. A central challenge in genome-wide RNAi research is to integrate both experimental and computational approaches to obtain high quality RNAi HTS assays. Based on our daily practice in RNAi HTS experiments, we propose the implementation of 3 experimental and analytic processes to improve the quality of data from RNAi HTS biotechnology: (1) select effective biological controls; (2) adopt appropriate plate designs to display and/or adjust for systematic errors of measurement; and (3) use effective analytic metrics to assess data quality. The applications in 5 real RNAi HTS experiments demonstrate the effectiveness of integrating these processes to improve data quality. Due to the effectiveness in improving data quality in RNAi HTS experiments, the methods and guidelines contained in the 3 experimental and analytic processes are likely to have broad utility in genome-wide RNAi research.

Importance Analysis

Organisational decision-makers have experienced the adverse effects of decisions based on information of inferior quality. Millions of dollars have been spent on information systems to improve data quality (DQ)1 as well as the skills and capacity of IT professionals. It is an important issue that the IT professionals align their work within the expectation of the organization’s vision. This chapter provides some theoretical background to DQ and establishes a link between DQ, performance-importance analysis and work alignment. Four case studies are presented to support the theory developed in this chapter and to answer the question as to whether the IT professionals consider DQ issues differently from other information users.
