    The document describes an alpha test of a survey questionnaire to test its internal consistency and reliability. It conducted surveys with 30 random employees and used Cronbach's alpha to measure reliability. The Cronbach's alpha values ranged from 0.69 to 0.88 for categories like effectiveness, efficiency, usability, satisfaction, freedom from risk, and context coverage. The overall Cronbach's alpha value was 0.79, indicating the test items were reliably consistent.

    Testing Plan

    Alpha Test

    To determine the reliability of one’s study, the most common

    instrument used is the survey questionnaire for gathering data. To test the

    internal consistency of test items, the proponents conduct a survey with thirty

    (30) random employee from different offices.

    One of the most popular method measuring the internal consistency or

    reliability of survey questionnaires or test items is Cronbach’s Alpha Reliability

    Test . On a study of A Review on Sample Size Determination for Cronbach’s

    Alpha Test: A Simple Guide for Researchers by Bujang (2018), et al. explains

    that the value of Cronbach’s alpha ranges from zero to one with the higher

    values implying the items are measuring the same dimension. In contrary, if

    the Cronbach’s alpha value is low (near to 0), it means some or all of the

    items are not measuring the same dimension. This means that test items are

    not reliably consistent from one another. To determine that the instrument is

    reliably consistent, it must be 0.7 considering it is the minimum range of

    Cronbach’s Alpha but some discussions state that 0.6 is considered

    acceptably reliable (Graupera, 2017). Moreover, instances that low number of

    items will always result to low rating. To have a more valid result, is much

    more reliable to calculate the correlation between items in this situation.

    The Cronbach’s Alpha concerning on the “Effectiveness” of the system is

    0.78. This means that the effectiveness of the test items is in the average

    point.

    Table 6: Cronbach’s Alpha of items user “Efficiency” category

    In the efficiency category shows that the Cronbach’s Alpha result is

    0.69. This only means that the ability of the system to do its job is inefficient. It

    stands as acceptable reliable considering that 0.6 is considered acceptable

    (Graupera, 2017).

    In table 7, the Cronbach’s Alpha results is 0.88 for the “Usability”

    category. This only means that the system is fit for its use and the questions

    68
    given are more than enough to be considered as reliable and consistent with

    other test items.

    Table 9: Cronbach’s Alpha of items user “Freedom from risk” category

    As shown in Table 11, the Cronbach’s Alpha result is 0.85 which

    means that the system is free from any risk. The system provides notifications

    that warns the user for any risk.

    Table 9: Cronbach’s Alpha of items user “Context Coverage” category

    The Cronbach’s Alpha result is 0.82 for the category of “Context

    Coverage”. The questions given are more than enough to be considered as

    reliable and consistent with other test items.

    (Cronbach’s Alpha Value of Effectiveness (0.78) + Cronbach’s Alpha

    Value of Efficiency (0.69) + Cronbach’s Alpha Value of Usability (0.88) +

    Cronbach’s Alpha Value of Satisfaction (0.73) + Cronbach’s Alpha Value of

    Freedom of Risk (0.85) + Cronbach’s Alpha Value of Context Coverage

    (0.82)) /6 = 0.79.

    The survey questionnaire or test items has a result of 0.79 in overall

    internal consistency, this concludes that the alpha test is reliable and

    consistent.
