In up-to-date conditions information technology is frequently associated with the modelling process, using computer technology as well as information networks. Statistical modelling is one of the most widespread methods of research of economic systems. The selection of methods of modelling of the economic systems depends on a great number of conditions of the researched system. Modelling is frequently associated with the factor of uncertainty (or risk), who’s description goes outside the confines of the traditional statistical modelling, which, in its turn, complicates the modelling which, in its turn, complicates the modelling process. This article describes the modelling process of assessing the economic efficiency of a multi-boiler adaptive heating system in real-time systems which allows for dynamic change in the operation scenarios of system service installations while enhancing the economic efficiency of the system in consideration.

The rise of mobile smartphones and its usage of mobile applications made the human life more productive and boosted several activities in everyday routine jobs and business areas. In another side now a day, most of the business and personal applications transferred to the mobile apps. The one hand mobile application providing more features than traditional desktop applicationas and proving endless opportunities for new ventures. Day to day mobile application are becoming a part of several model device with different mobile operating system such as Android, iOS, Windows, BlackBerry, Symbian, etc. and it becomes challenging to development and quality assurance teams to verify and validate mobile app that works on end-user mobile with no error. With growing technology, mobile application development companies adopted new tools and work in different development approaches such as waterfall, agile, prototyping [1], [2], [3] but still, challenges are same for the quality assurance team to test the application and make application error free in the dedicated short time. The testing mobile application becomes more challenging due to the growing number of devices by the different vendor and test on all possible devices sometimes impossible for the quality assurance team. The mobile application testing team most of the time face challenges related to the usability, interrupts, poor connections, device settings with functional and non-functional testing issues. In such situation, test planning and building more proper test strategy to cover all aspects will lead to making application error free. From many years, lean canvas boards are used for the developing business plans, strategy and for risk analysis. This paper is focuses on the re-design and develop lean canvas design using lean principles to use it for the mobile application testing process and it can affect precisely on app testing quality, resource, cost and time.

The paper introduce to challenges in automation of continuous processes in companies with many active software development projects. Usually companies have automation solutions for particular projects. When new software development projects are coming, companies would like to save up resources and efforts needed for automation solutions in these projects. In case when automation solutions, implemented in existing projects, are reusable, they could be used in new project without additional efforts for refactoring, development automation solution from scratch etc. Current paper provides an approach for development of library of reusable functions. This library allows reusing implemented automation functions in the different projects and in the different workflows. Finally, a prototype is developed for practical experiments. Based on its results, benefits, disadvantages and improvement directions of provided approach are detected.

Everyday software usage is increasing with technological advancements and the deep integration of technology and human life. Moreover, software dependency also increases from day-to-day task to do it in an easy way. In a recent year software development has seen high growth in a number of tools and technology for building better software for end users. Software development adopted different approaches such as waterfall, prototyping, incremental development, iterative, spiral development, rapid application development, lightweight methodologies and other to develop software and at the same time software testing also needs to be done in the scope of time and budget. Software needs to be well tested in main functional and extra-functional properties requirements point of view. In software life cycle at some point it is important to consider the testing extra functional properties before delivering the software application to end user. It is important to create a basic level of checklist for the testing extra-functional properties to make sure the software is delivered error free. In testing, it is noticed that it is difficult to make test strategy, design tests cases in all possible way for the testing extra-functional properties. In such a scenario, the utilization of lean canvas to identify and use all testing extra-functional properties can make test planning and test design easier. It also helps to track and manage an individual tester’s or test team’s all possible testing extra-functional properties on one page. In business many years the lean canvas used only in business planning and strategy building, but well optimized lean principle adopted lean canvas board can bring many benefits for the testing extra-functional properties.
