Software reliability modeling has‚ surprisingly to many‚ been around since the early 1970s with the pioneering works of Jelinski and Moranda‚ Shooman‚ and Coutinho. The theory behind software reliability is presented‚ and some of the major models that have appeared in the literature from both historical and applications perspectives are described. Emerging techniques for software reliability research field are also included. The following four key components in software reliability theory and modeling:

One way to think of reliability is that other things being equal‚ a person should get the same score on a questionnaire if they complete it at two different points in time (test-retest reliability.

Introduction This research work focuses on the various aspects of evaluative standards like reliability and validity. Alongside the research work here describes the various phases in a selection process and a case study which help understand how reliability and validity can be examined and achieved over the entire selection process.

Introduction Reliability and Validity are often applied as a commonly in a qualitative research and it has been considered the main point of the researches. Therefore‚ in order to be used in a naturalistic way they would have to be redefined; in a point where there are positioned or based on positivism. When an assessment or other measuring techniques are used as the main part of the collection process‚ which it leads to the importance of validity and reliability of the assessment. Assessment

4.3 Reliability Analysis According to Saunders et al. (2009)‚ reliability test is an indicator of measure for internal consistency and to ensure the quality of the questionnaire. In order to achieve a more accurate questionnaire‚ this study used the Cronbach’s Alpha which is the most popular model to determine the correlation among the items and to assess the internal consistency of a questionnaire (or survey) that is made up of multiple Likert-type scales and items.

As the need for a well-planed‚ effective and safe maintenance has emerged‚ a complex methodology has been designed. It is called Reliability Centred Maintenance. Such methodology is applied to various contexts of maintenance so that there has been a little agreement on what is a real purpose of such approach. Therefore‚ current paper lingers upon the analysis and contextualization of
