Relationship between the quality and reliability of information

The quality of information and credibility are closely related. Quality aspects of information are not necessarily consistent, so you may need to support the assessment of information quality by evaluating the reliability of information. Some information may seem up-to date but inaccurate as well as accurate but useless. Therefore, credibility is a basic element of information that is reflected in the authenticity and its elements are true. The ability to assess the reliability and quality of information is one of the basic features. Usability, specificity and correctness are most the commonly used criteria in assessing the quality of information. On the order hand, knowledge and reputation are the main criteria in assessing credibility. The credibility of information is closely related to the possibility of its verification and evaluation of its sources or the faithful representation of the features of objects, processes or phenomena[2].

Quality of information and decision making

The quality and quantity of information are important factors influencing the effectiveness in making decisions. In the decision-making process, information indicates both the decision problem and help solve it. Decisions transform information into action instructions in a given situation, taking into account the purpose of the action and the selection criteria. The definition of information is also knowledge oriented towards the decision-making objective, which means that the value of information is mainly generated by the degree of goal realization. The most important attribute of information is its significance, which means matching information to solve specific decision problems. According to this attribute, it is required that the information be usefully linked to activities that are to produce specific results. The importance of information in the decision process is primarily influenced by the strength of the relationship: information need - decision/effect. The quality of information helps to assess the product's characteristics, as well as to choose the one that will be more attractive and meet its expectations. Accurate information on product evaluation leads to greater consumer satisfaction and an increase in the quality of decisions made by them[3].
