Evolution of Professional Competencies of a Web Developer

The relevance of the article lies in the fact that the activity under consideration — web development as a whole is a popular programming industry. Many companies transfer their business processes to the Internet, and provide users with access to their data, solutions and services. In this regard, there is a shortage of IT specialists of this qualification — web developers. And if we take into account the rather rapid change of technologies, which concerns both programming paradigms and just the release of new versions of software, such as server, programming languages, programming system, frameworks, then methods of professional development of web developers become especially relevant. The purpose of the study is to determine the most effective way to develop a web developer in the company. This includes determining the needs of the company and the skill level of the developer and reducing the difference between these indicators. The task is to determine the method of optimal assessment of the level of qualification, offer points of measurement of this level, and analyze the effectiveness of advanced training. The article raises the problems of effective professional development of employees of web development companies. The way of development of a ready-made specialist is considered, depending on the skill level of the developer, the level of project requirements and updating of the main software. Methods used: empirical research, classification methods. The methods of evaluation and training of employees were analyzed using the example of companies leading web development. The result of the research is a model of web developer competencies, recommendations for assessing the levels of knowledge and skills of employees, recommendations on the level of implementation of new technologies.

Optimal profitable applications for web development companies using a linear programming approach

The consumed resources in web development companies are different and greatly affect a company’s profit or loss extent. We will utilize linear programming to measure that and maximize the company’s profit. Furthermore, we will apply the simplex method algorithm within certain constraints placed on different components of the company's different products. This problem can be solved with a trial and error approach but this requires great effort and time, which is a challenging thing to do on each product. We can employ different computer tools that calculate and solve these problems. Microsoft Excel is one of these tools that solve linear programming equations and provides accurate outputs; there are plugins such as (Solver) that work in integration with Excel. This paper’s main goal and purpose are to calculate and acquire the ideal products that maximize the company's profit under certain constraints. The best distribution and optimal use of resources to increase profit while maintaining quality and quantification of each project type with imposed restrictions and steps that the company must take to stop and reduce excess and unused resources. The simplex method algorithm is used because it is faster than other algorithms in solving linear programming problems, and it has high efficiency in reducing the needed resources for computer processing. On the other hand, the limitations of this algorithm manifested in its dependence on variables will increase the complexity of the problem, and this cannot be implemented accurately in all cases of linear programming problems.

Factor reduction and clustering for operational risk in software development

Software development failures frequently emerge as a result of the failure to understand and identify risks. The aim of this paper is to identify the most salient risk factors present during a software development project's life cycle, in terms of their occurrence likelihood and impact on cost overrun. A questionnaire was sent to 2000 software development companies, IT consultancy and management companies and web development companies in the United Kingdom, United States, mainland Europe, Canada, Australia, India, China, Japan and other Asian countries, asking respondents to evaluate a number of risk factors. Because many factors were closely related, we applied a factor reduction and clustering process to the results to allow a smaller number of crucial risk factors to be identified. The three main clusters of risk factors we identified are feasibility studies, project team management and technology requirements. While a feasibility study may be unlikely to take place, it can have a significant impact on project outcomes. In contrast, project team management is likely to occur but has a relatively small impact on outcomes in comparison with technology requirements. Professionals will need to apply checks and balances to these factors and generate risk mitigation plans to reduce the severity of project failures. Our results allow them to connect the probability of risk factor occurrence and overall impact, so they can focus their limited resources on reducing the most pertinent risks in their projects.

User Testing is Not a Luxury

Companies need to address Web Accessibility with more than just professional standards of code writing, and adherence to the Web Content Accessibility Guidelines. With funding from the European Social Fund a team at Salford University, led by the authors, undertook a research project in 2007 entitled Combating eDiscrimination in the North West. The research examined over 100 websites advertising job opportunities both regionally and nationally, and found the vast majority to be largely inaccessible. Professional standards, such as using valid W3C code and adhering to the W3C Web Content Accessibility Guidelines (1999), were largely not followed. The project also conducted interviews with both public and private sector web professionals, and focus groups of disabled computer users, to draw a broader picture of the accessibility of jobs websites. Interviews with leading web development companies in the Greater Manchester region, showed that there is a view there should not be any additional cost in making w...

Web hypermedia cost estimation: further assessment and comparison off cost estimation modelling techniques

Research into Web cost estimation is relatively new, where few studies have compared cost estimation modelling techniques for Web development, with an emphasis placed on techniques such as Case-based Reasoning (CBR), linear and stepwise regression. Although in a large subset of these studies CBR has given the best predictions, results were based on a simple type of CBR, where no adaptation rules were used to adjust the estimated effort obtained. In addition, when comparing the prediction accuracy of estimation models, analysis has been limited to a maximum of three training/validation sets, which according to recent studies, may lead to untrustworthy results. Since CBR is potentially easier to understand and apply (two important factors to the successful adoption of estimation methods within Web development companies), it should be examined further. This paper has therefore two objectives: i) to further investigate the use of CBR for Web development effort prediction by comparing effort prediction accuracy of several CBR techniques; ii) to compare the effort prediction accuracy of the best CBR technique against stepwise and multiple linear regression, using twenty combinations of training/validation sets. Various measures of effort prediction accuracy were applied. One dataset was used in the estimation process. Stepwise and multiple linear regression showed the best prediction accuracy for the dataset employed.
