Open-source software has also spread to commercial area as companies had noted its undisputed benefits. However, open-source software has always been accused of lack of quality and reliability. Most used argument for this is that open-source development process does not use traditional quality assurance techniques and methods used in commercial development. This essay reviews quality assurance process in open-source development, methods, processes and techniques which provide quality of open-source software. This paper also aims to compare quality of open-source and commercial software and tries to answer question if open-source software really has less quality than commercial software. In the end this essay tries to think of possibilities of using open-source quality assurance in commercial development.

The work discusses the various ways to eliminate this space, to keep track of process errors, look for critical points of error, and exposing of them. I watch differences between the occurrence and detection of "large" errors in this paper, those that are visible both in terms of detection, but also visible in the form of consequences that their failure brings. The work focuses on the phenomenon of error of negligence, carelessness, which generates the vast majority of software defects. At first, glance seem insubstantial, but ultimately unsuitable for a large number of combinations for a correct functioning of critical software defects.

The joy of monitoring

Králik Gergely

Abstract. The process of project monitoring is the possibility to learn about the state of the project development. Using project monitoring we can estimate the quality of the program, also we can measure the efforts of the individual members of the team. Now, when the agile software development is widely used we need to invest more time to the project monitoring, so we can estimate the risks, and avoid errors. The term monitoring can means monitoring of the code quality, but also means monitoring the team members as individuals. So we can determine if they work according to the plan. Monitoring consists of three main elements: collection, analysis and preparation of records. This paper describes how to monitor projects using metrics for monitoring in software development. This essay describes the options of observing the quality of the work or the process of the task allocation.

Software quality in everyday life

Kyžňanský Michal

Abstract. Word quality and mainly the one referring to software represents a magical concept which unfortunately suffers from being unfulfilled from the very beginning of usage of word software. Every management mainly deals with the people and that is the reason why I as a quality manager focus on approach to the people, how to be closer to them and pull the whole development team in a nonviolent way to achieve new levels of software quality. Quality manager often experiences sciamachy because on the one hand flawless software is utopia and on the other introducing new practices that will raise the quality level is not an easy task. Programmers ego and old established practices are just a few of the many problems that are waiting to be solved by quality manager. I am focusing mainly on the procedures and behaviour which can result in reduction of problems connected to quality crisis if properly established and integrated. Important weapons that quality manager can use is sensible approach, gaining trust on every level of organisation and development team and setting objectives. Fulfilling of these objectives must be measurable and in the end will increase quality not only in front of customers but also give programmers sense of good work. To be successful as a quality manager owners and managers must clearly see the benefits brought by activities connected to quality management by means of reducing costs for future development.
