From table: 05, status of the organization section all 70 employees belong to foreign subsidiary company. From table:06 there are 7 respondents who worked for the company about Less than 6 Months, there are 13 respondents who worked for the company about 6 months-1 year, there are 11 respondents who worked for the company about 1 year-1.5 years, 10 respondents are who worked for the company about 1.5 years-2 years, and 29 respondents who worked for the company above 2 years. 3.11) Reliability Analysis Cronbach’s alphaCronbach alpha is a coefficient of internal consistency. It is commonly used as an estimate of the reliability of a psychometric test for a sample of examinees. In other words, it measures how well a set of variables or items measures a single, one-dimensional latent aspect of individuals. Observation Cronbach‘s alphaprovides a useful lower bound on reliability. Cronbach‘s alpha will generally increase when the correlations between the items increase. For this reason the coefficient measures the internal consistency of the test. Its maximum value is 1, and usually its minimum is 0, although it can be negative (see below). A commonly-accepted rule of thumb is that an alpha of 0.7 (some say 0.6) indicates acceptable reliability and 0.8 or higher indicates good reliability. Very high reliability (0.95 or higher) is not necessarily desirable, as this indicates that the items may be entirely redundant. These are only guidelines and the actual value of Cronbach‘s alpha will depend on many things. E.g. as the

The goal in designing a reliable instrument is for scores on similar items to be related (internally consistent), but for each to contribute some unique information as well.A commonly acceptedrule for describing internal consistency using Cronbach's alpha is as follows: Cronbach‘s alpha Internal consistency α ≥ 0.9Excellent (High-Stakes testing) 0.7 ≤ α < 0.9Good (Low-Stakes testing) 0.6 ≤ α < 0.7Acceptable/ Sufficient 0.5 ≤ α < 0.6Poor α < 0.5Unacceptable The value of cronbach‘s alpha for Autonomy in table no: 07 is .945 which is an excellent value.The value of cronbach‘s alpha forSkill Variety in table no: 08 is .850 which is a good value. The value of cronbach‘s alpha for Feedback in table no: 09 is .844 which is a good value. The value of cronbach‘s alpha for Training Opportunity in table no: 10 is .877 which is a good value. The value of cronbach‘s alpha for Work-Life-Balance in table no: 11 is .946 which is an excellent value. The value of cronbach‘s alpha for Employee Performance in table no: 12 is .910 which is an excellent value.
