SCU: Kevin's Farm Information System Report, Data Analysis & Design

This report provides a comprehensive analysis of the Kevin's Farm Information System, addressing the need for an automated system to manage increased farm complexities. The report begins with an introduction to Kevin's Farm, detailing its operations and challenges. It then explores data gathering activities, focusing on interview techniques, including how interviews are conducted, interview questions, and the advantages and disadvantages of this method. The report continues with the development of various UML diagrams, including use case descriptions and diagrams, activity diagrams, an Entity Relationship Diagram (ERD), a Domain Model class diagram, and a System Sequence Diagram. These diagrams are used to visualize the system's functionalities and database schemas. The report concludes with a summary of the findings and references used.

PART B.
Introduction.
The Kevin is the owner of the farm and was initial started by Kevin and his friend. The farm is
run by Kevin and his wife Mary. They also have other workers who help in the operation of the
farm. The farm started in their home later it expanded. The Kevin’s farm produce is produced
organically and these produces are certified vegetables, fruit and nuts, honey, decorative plants
and eggs. The permaculture principles and biodynamic soils is used to grow these farm produce.
The farm was started at Kevin’s home. The farm was started as a need of organic grown food by
the community.
The farm has expended from being domestic farm with small number of customers into the huge
commercial farm producing a lot of farm produce. Kevin has decided to use one of the spaces of
their home farm which was used for grazing cattle to expand on his farming activities. Kevin
works with his friend, wife and has workers who he recent employed from the Southern Cross
University’s Plant Science faculty to help in managing a farm.
Due to increase in produce of large volume of farm produce, animal output and in the increase of
customers name and demand of the Kevin’s farm produces. Kevin find it difficult to monitor and
track farm activities well. So, there is need to develop the information system that shall help in
managing the increased farm complexities.
There is need to automate farm activities by developing the farm information system that shall
make farm activities more efficient, effective and secure while making their customer satisfied
This report shall explain data gathering techniques such as interview(Satzinger et al. 2016).. The
data collecting is to be done and analyzation of the collected data. Different UML diagrams shall
be drawn after analysing the data collected and case study of the Kevin’s farm (Lethbridge and
Laganiere,2016). This report shall have facts from the analyzation of the business need and
suggestions to the required changes. This report shall be used as a tool to implement the
information system (Sommerville, 2016).

5. Data Gathering Activities.
The interview is to be conducted between consultant and the workers to collect vital information
that shall help in the development process of the system (Agarwal and Goel, 2014).
How interview is conducted.
Determining the goal of the interview is being established.
What kind of information is needed to be obtained?
Is information able to help in improving the system?
Is the interview information solution to the research?
Identify the interviewee.
The participant should have knowledge about the information you need to obtain.
The goal of the interview is also considered during identifying the interviewee (Sommerville,
2016)..
Schedule appointment with the interviewee.
Obtain appropriate date and time for the interview.
Prepare the interview guide.
The open-ended questions are formulated.
There is need to avoid leading questions.
There is need to create clear and easy to understand interview questions.
The interview questions are to be focusing on the goal of the interview and should have a room
to be adjusted thus make them flexible.
The interview questions should be in align with data gathering and analysing goals.

Conducting interview.
Meet the interviewee at the scheduled place, time and date (Sommerville, 2016).
Giving interviewee the interview questions.
Start interviewing the interviewee.
Recorded the interview.
The interview can be recorded on the piece of paper, recorded using audio or video (Satzinger et
al. 2016).
Transcribe and analysing the interview.
After obtaining the recorded data from the interview there is need to analysis the data to
obtaining useful data that is helpful in the implementation of the Kevin’s information
system(Satzinger et al. 2016)..
Gathering process ends.
The data is finally gathered and this data meets the system requirement.
Interview Questions

Advantage of the interview.
The interview is flexible because the interviewer can adjust on the type of the question to ask but
the questionnaires the questions are fixed nothing can be added again (Dick et al. 2008)
There is high response rate during interview because workers how are not able to write and read
are able to take part in the interview by answering questions (Dick et al. 2008).
The interviews help in capturing the no-verbal behavior of the participant because there is face to
face interaction with the respondent (Agarwal and Goel, 2014).
The interviews help in obtaining detained data because the interviewee is able to provide extra
information in his/her area of expert that the interviewer may not have knowledge with.
Disadvantage of the interview.
Expensive
The interview is costly because it requires employees to enable interview to take place.
The information collected mostly depends on the interviewer’s ability and skills in conducting
interview and gathering information well (Agarwal and Goel, 2014)..
Most interviews are conducted manually and information collected is transferred into soft copies.
Small sample size.
Most interview are conducted on small group of people as compared to the questionnaire which
cover a lot of people. This make interview to have limited size (Dick et al. 2008).
Limited time

Interview are time consuming because there is need to schedule and plan for the interview.
