The utilization of ontologies in knowledge management has become very well accepted in many approaches for instance database, semantics, agent, natural language processing, etc. Artificial intelligent researchers have originally applied the word "ontology" from Philosophy fields which means "being existence", then the word spread in many scientific domain and ontologies are now used in several developments. The purpose of this research is to present the simple methodologies and methods used to build/adapt/integrate ontologies from the system requirement or by reusing and re-engineering other ontologies; also a process of merging approach will be addressed. The normal ontology engineering will not be suitable for non-expert user; and there are some tools for helping the user to accomplish the ontology engineering task, however, it is not that simple. This paper mentioned the observation and figure out the practical methodology for non-expert user to learn and create simple ontology with little background of them. This paper mentioned the ontology and ontology engineering revisits. Also the main section in this paper mentioned the scenario walkthrough about reality of how non-expert user creates the simple ontology by using suggested and existing methodologies. The last section is recommendation and suggestion from the research experimental which explain the proper ontology developing methodology for non-expert user.
