Improving the Management of Cost and Scope in Software Projects Using Agile Practices  [PDF]
Mariana de Azevedo Santos,Paulo Henrique de Souza Bermejo,Marcelo Silva de Oliveira,Adriano Olimpio Tonelli
International Journal of Computer Science & Information Technology , 2013,
Abstract: While organizations want to develop software products with reduced cost and flexible scope, stories aboutthe applicability of agile practices to improve project development and performance in the softwareindustry are scarce and focused on specific methodologies such as Scrum and XP. Given these facts, thispaper aims to investigate, through practitioners' perceptions of value, which agile practices are being usedto improve two performance criteriafor software projects—cost and scope. Using a multivariate statisticaltechnique known as Exploratory Factor Analysis (EFA),the results suggest that the use of agile practicescan be represented infactors which describedifferent applicationsin software development processtoimprove cost and scope.Also, we conclude that some agile practices should be used together in order to getbetter efficiency on cost and scope in fourdevelopmentaspects: improving (a) team abilities, (b)management of requirements, (c) quality of the code developed, and (d) delivery of software on-budget andon-time
Work Issues in Software Engineering  [PDF]

Computer Science , 2013,
Abstract: Using data from a web-based survey of software developers, the author attempts to determine root causes of "death march" projects and excessive work hours in the software industry in relation to company practices and management. Special emphasis is placed on the factor of business/technical supervisor background. An analysis of variance revealed significant differences between these supervisor groups with regard to a "Pointy-Haired Boss" (PHB) sentiment index. This difference, combined with correlations between the PHB index and the endpoints of project failure and use of software engineering practices, indicate some disparity in the suitability of businessbackground supervisors to manage software development projects compared with their technical-background counterparts. Other survey data points to improved project management skills as the biggest necessity for supervisors in the business-background group.

Abstract: While organizations want to develop software products with reduced cost and flexible scope, stories about the applicability of agile practices to improve project development and performance in the software industry are scarce and focused on specific methodologies such as Scrum and XP. Given these facts, this paper aims to investigate, through practitioners' perceptions of value, which agile practices are being used to improve two performance criteria for software projects-cost and scope. Using a multivariate statistical technique known as Exploratory Factor Analysis (EFA), the results suggest that the use of agile practices can be represented in factors which describe different applications in software development process to improve cost and scope. Also, we conclude that some agile practices should be used together in order to get better efficiency on cost and scope in four development aspects: improving (a) team abilities, (b)management of requirements, (c) quality of the code developed, and (d) delivery of software on-budget and on-time.

PLOS ONE , 2013, DOI: 10.1371/journal.pone.0071119
Abstract: Setting Private medical practitioners in Visakhapatnam district, Andhra Pradesh, India. Objectives To evaluate self-reported TB diagnostic and treatment practices amongst private medical practitioners against benchmark practices articulated in the International Standards of Tuberculosis Care (ISTC), and factors associated with compliance with ISTC. Design Cross- sectional survey using semi-structured interviews. Results Of 296 randomly selected private practitioners, 201 (68%) were assessed for compliance to ISTC diagnostic and treatment standards in TB management. Only 11 (6%) followed a combination of 6 diagnostic standards together and only 1 followed a combination of all seven treatment standards together. There were 28 (14%) private practitioners who complied with a combination of three core ISTC (cough for tuberculosis suspects, sputum smear examination and use of standardized treatment). Higher ISTC compliance was associated with caring for more than 20 TB patients annually, prior sensitization to TB control guidelines, and practice of alternate systems of medicine. Conclusion Few private practitioners in Visakhapatnam, India reported TB diagnostic and treatment practices that met ISTC. Better engagement of the private sector is urgently required to improve TB management practices and to prevent diagnostic delay and drug resistance.

Pratima Singh,Anil Kumar Tripathi
International Journal of Software Engineering & Applications , 2012,
Abstract: Software Development has started experiencing the need of consideration of NFR (Non FunctionalRequirements) for producing high quality acceptable software. Mostly software engineering literature hasconsidered only for testing Functional Requirements. In context of such a need this work attempts toconsider NFR, resulting from quality concerns of stakeholder, along with their impact and effect on testing.We identify and bring out issues, in testing of NFR that warrant, purposeful and meaningfulconsiderations.

PLOS ONE , 2014, DOI: 10.1371/journal.pone.0095706
Abstract: Background Several studies suggest that men and women are treated differently for similar disease including diabetes and cardiovascular disease. Differences in attitudes and treatment practices towards men and women with obesity are not well recognized. Objective To investigate the attitudes and treatment practices among Danish general practitioners (GPs), in relation to treatment of overweight, while taking gender of both the patients and practitioners into account. Design Questionnaire inventory covertly examining attitudes and practices among Danish general practitioners towards treatment of overweight. All 3.637 general practitioners from the Danish Medical Association register were invited to participate in the survey. In total 1.136 participated. Results The GPs found weight loss to be more important for overweight male than overweight female patients. They also treated complications to overweight more rigorously among male than female patients, and recommended lipid lowering medicine more often to male than female overweight patients. In addition, the younger female GPs and older male GPs more often said that they would treat an overweight patient with lipid lowering medicine. Conclusion Among general practitioners in Denmark, treatment for weight loss is more often practiced for overweight male than overweight female patients presenting with same symptoms. In addition, hyperlipidemia among overweight males is also more often treated with lipid lowering medicine than hyperlipidemia among overweight females.

Journal of Environmental Protection (JEP) , 2018, DOI: 10.4236/jep.2018.96045
Abstract: The use of good practices (GP) can improve the technical quality and, as a consequence, the outcome of the Strategic Environmental Assessment (SEA) process, increasing its effectiveness. This study aimed to present GP pointed out by Brazilian practitioners (members of the SEA development teams) from the perspective afforded by their participation in processes of this tool. The data were collected through personal interviews with 11 professionals responsible for preparing a total of 17 SEAs, who were asked about what measures adopted in the SEA could be considered BP. The responses were audio-recorded, transcribed, and had their content assessed by Content Analysis technique. Nine GP were highlighted by practitioners. The GP indicated represent a valuable contribution to the improvement of future use of SEA, either in Brazil or in other countries, because they are the result of consolidated experience in real cases of application of the tool.
General Practitioners' Familiarity, Attitudes and Practices with Regard to Attention Deficit Hyperactivity Disorder in Children and Adults
C Louw, M Oswald, M Perold
South African Family Practice , 2009,
Abstract: Background: Attention-Deficit Hyperactivity Disorder (ADHD) is a common disorder, affecting 4% to 5% of South African children. Recent studies reveal that 30% to 70% of children continue to experience problems related to ADHD in adulthood. Adults are becoming increasingly aware of adult ADHD as a result of public awareness campaigns in the media. Their first line of action is to visit their family physician (GP), but the question that arises is whether these practitioners are ready to take on patients with ADHD. The aims of this study were to determine the familiarity, attitudes and practices of general practitioners (GPs) in South Africa with regard to ADHD in both children and adults, and whether there are differences in children and adults with regard to depression and generalised anxiety disorders as comorbid disorders. The study also briefly explored the training models of GPs in South Africa. Methods: The research questions were addressed by means of a survey approach, using quantitative measures. An e-mail message with a covering letter, explaining the purpose of the research project, provided a link to a web-based questionnaire. It was relayed to 6 704 GPs on the database of the company MEDpages, which managed the distribution. A questionnaire attached to an e-mail message was sent to all departments of Family Health at universities in the country to obtain information with regard to the training models of GPs. The questionnaire was completed by 229 respondents. The data were statistically analysed using Statistica Version 7.0. Results: The most significant outcome of the study revealed a considerable need among GPs to increase their knowledge base with regard to ADHD (87% with regard to children and 89% with regard to adults). As they were of the opinion that they should be able to diagnose and manage ADHD in both children (90%) and adults (85%) a significant need for a screening tool (83%) was also found. The GPs’ knowledge and training with regard to depression and generalised anxiety disorders were significantly more extensive with regard to adults than to children. Training with regard to ADHD in adults was almost non-existent. With regard to children the most important barriers were uninformed parents (70%), limited funds (61%), uninformed teachers (58%), and with regard to adults these barriers were uninformed patients (64%), lack of knowledge on ADHD in adults on the part of the GPs (63%), and consultation time (58%). Although GPs did seem to have an awareness of the important role of the psychologist in the diagnosis and effective management of patients with ADHD, their referral practices generally involved a limited interdisciplinary approach. Conclusion: It is recommended that the limited knowledge base of GPs with regard to ADHD should be addressed by adapting the curriculum of undergraduate medical students and providing opportunities for continued medical education that focuses on the diagnosis and management of ADHD, in bot
