4. RESULTS AND DISCUSSION
The questionnaire consists of ten questions as listed in table 1. It was
filled out by the users. For each question they chose one of (Strongly
Disagree, Disagree, Neutral, Agree and Strongly Agree) which scored from
1 to 5 respectively.
As the results show, for questions 2, 3 and 7, 100% of the participants
chose strongly agree i.e. they confirm that the system is easy to use.
They also strongly agree that the system could easily be used with
different devices and they recommend it to other supervisors of electric
power generators.
92% is the result for question 1, 4, 6, 8, 9 and 10. This indicates
that the users agree with the language used in the system. It worth
mentioning that Kurdish language is used in the system and it makes it
easier for them since it is their native language. The participants are
willing to use the system in the future as it increases efficiency and
accuracy in the management process.
Concerning the interface of the system, question 6, the results show
that the preference rate is 72%. Result of this question compared to
other questions is the least. But the interface can be improved more in
the future with the users’ demand when updating the system.
For the interview part, five questions were answered by the supervisors
of the electric power generator. The questions focus on the time and
money spent in preparing receipts as well as updating information with
and without the system and how it facilitates the process.
The first question was “how much time does it take for preparing the
receipts with and without the system?”. The supervisors said that they
needed 15 to 20 hours each month in preparing the receipts. But now it
takes only 25 minutes to half an hour to prepare them and this is a very
big difference as depicted in figure 11.
Concerning the second question which was about the cost, the supervisors
stated that before using the system they spent 18,000 to 20,000 Iraqi
dinars per month with the system they need only 1,500 Iraqi dinars. So,
it saves around 85% of the cost. Differences of the cost are
illustrated in figure 12.
The third question was about updating information of the customers in
the boards with and without the system. It was confirmed that before the
system they had to do a lot of paper-work daily to update information
for example; they were using notebooks, after updating less than ten
customers’ information they had to change the notebook and rewrite the
entire information, which was really tedious as they mentioned. On the
opposite, with the system they need only a few minutes to update
information.
In answering the fourth question, about the help they get from the
system in calculating total amperes, price, expense and profit, they
replied that the system makes the work significantly easy. Previously,
they needed a calculator, pen and paper and a lot of time to do the
calculations.
The last question was left to them to comment about the system in
general. Most of them said that the system makes a lot of
simplification, accuracy, faultlessness in the management process. On
the contrary, lots of mistakes were happening in calculation of total
price, profit, expenses, total number of customers and amperes.
