The world that we see and in which we live is driven by open source platforms. Whether we talk about Linux and Apache or Drupal and Joomla (all are open source platforms), right from the beginning the open source technology has always been influencing. If we go online and try to find out open source link, we find that it is difficult to find a site/online application without an open source connection. This paper examines Free and Open Source Software (FOSS) in an empirical setup in terms of its major characteristics i.e. Deployability and Usability. These two characteristics of FOSS are ex-tremely important from point of view of its comparison with proprietary software. The different attributes of FOSS were identified in the literature and were made part of the present study to carry out empirical analysis of FOSS. Apart from this a number of attributes were also included in this empirical study those were agreed upon by the participants while carrying out pilot study. This paper throws light on the experience of different kinds of users associated with FOSS. The statistical analysis using fisher's exact test was used to conclude the dependability of important characteristics of FOSS on each other.
