Consider a research paper submission process. The process starts when an author submits a draft research paper (the paper may have up to 3 authors) to the chair of the organizing committee of an international conference. Upon receiving the paper, 2 reviewers are assigned the exercise to review the paper and submit a report with comments and scores for the various selection criteria which are originality, relevancy, practicability, language and future work. Each criterion is assessed on a scale of 10 marks. If the total mark is 30 and originality is given 6 or above, the authors are notified about acceptance of the paper. The authors are then requested to re-submit the paper according to the conference format in .pdf and to submit a duly filled and signed copyright form necessary for publication. Moreover, at least one of the authors should register that is complete a registration form with payment effected before a specified date for the paper to be published in the conference proceedings.  Concurrently, all the authors are sent an invitation letter for visa procedures and access to the conference premises and the process ends.
