Putting Java to Work
Spring 2017/2018
Total Marks: 20
Plagiarism Warning:
As per AOU rules and regulations, all students are required to submit their own TMA work and avoid plagiarism. The AOU has implemented sophisticated techniques for plagiarism detection. You must provide all references in case you use and quote another person's work in your TMA. You will be penalized for any act of plagiarism as per the AOU's rules and regulations.
Declaration of No Plagiarism by Student (to be signed and submitted by student with TMA work):
I hereby declare that this submitted TMA work is a result of my own efforts and I have not plagiarized any other person's work. I have provided all references of information that I have used and quoted in my TMA work.

Practical Problem
This course is designed to mainly develop the programming skills of learners. In addition, the students should critically think to resolve problems. From this concept, this TMA is prepared.
In this TMA, each student is asked to write a java program which can calculate the average grades of the courses that has been completed by each particular student during the last two semesters Spring 16/17 and Fall 17/18. Please go through the following specification in order to complete this TMA successfully:
The program can be implemented using either JApplet or JFrame classes.
The courses and grades that was completed on Spring 16/17 should be hard-coded as variables in the code itself (e.g. int M105=80) and the grades should match your marks according to the SIS records.
The courses and grades that was completed on Fall 17/18, should be read through a GUI interface as follows:
o The user should be asked to enter the number (n) of courses completed on Fall 17/18.
o Based on the entered number and after pressing the button Click, the GUI should show n text fields to allow the user enter the course code and the corresponding grade as shown in the Figure below:
After entering the grades of the courses (according to your transcript from SIS), the student should press the button Calculate Average on the GUI.
This button should calculate the average of all courses studied in the two semesters. The program should calculate the average grade by summing up the total marks of the hard-coded courses in the program + the marks of the courses entered on the GUI interface, then divide it over the total number of courses as per the example below:
Hard-coded courses in Spring 16/17
int m105 = 70
int m129 = 88
int T175A = 77
GUI courses in Fall 17/18
When pressing Calculate Average, the result should be ((70+88+77) + (90+55+65+78))/7 = 74.2%
Important notes:
Copy & Past is not allowed and subjected to AOU plagiarism policy.
All the marks used in the code and entered in the GUI should exactly match the student transcript from SIS.
A copy from your transcript extracted from SIS should be included in the submitted file.
Students who fail in submitting the copy of his/her transcript or entering incorrect grades will result in awarding the student ZERO.
The code should be copied and pasted on the Word document and NetBeans Project should be submitted as well
Note that the title of the GUI interface should include studentsID_students name.

T205B SYSTEMS THINKING THEORY & PRACTICE
2017/2018 SEMESTER II
T205 B - TMA- Semester II - 2017 2018
_____________________________________
Question 01 (100 % marks)
(a) Read through the attached Case study Toshibas Accounting Scandal. As you read through the article create one spray diagram to summarize the case content respecting the conventions, and techniques. It is advised that students submit hand drawn diagrams as opposed to computer generated ones. Photocopies of diagrams should not be accepted. Reflect on your diagram in no more than 200 words. (15% marks).
(b) Based on what you learned in T205B concept file 04 section II Control, and based on the content of the article, and taking Fixing corporate culture as your goal draw one closed loop control model diagram to show the various inputs, and the transformation process, that can lead to reaching this goal. You need to show all the components of the control model diagram, the inputs, processes, control (actuator, comparator, sensor), that can lead to goal achievement . Reflect on your diagram (15% marks)
(c) Using an essay format of no more than 2500 words, and based on what you learned in T205B concept file 04 section I Organizations are They Rational, readings 01 and 07, section III Structure, section IV development, section V culture and climate, and section VI Decision Making and based on the ideas put forth in the attached case study:
1- Discuss the concept of organizational goals and the three categories of goals, and assess the existence of goal displacement and pluralism at Toshiba. (Word Count 500; 15 Marks)
2- Discuss the management approach at Toshiba, and the extent of employees empowerment and teamwork. (Word Count 250, 05 Marks)
3- Discuss the concepts of organizational culture and climate and assess Toyotas culture and climate. (Word count 400; 10 Marks)
4- Assess the extent to which Toyotas culture and climate and the unwritten rule of behaviors lead to the accounting scandal, (Word count 400; 15 Marks).
5- Discuss the different perspectives on decision making and assess how the decision-making process at Toshiba has affected the managers ability to resist pressures to inflate profits from top management (Word count 400; 15 Marks).
6- The investigation report mentioned that the interference of old generation of managers and their refusal to fully retire affected organizational culture and performance. Discuss the concept of organizational learning, and assess how the older managers attitude and power, can affect Toshibas ability to be a learning organization; justify your answers with evidence from the case (300 words; 10 Marks).
(a) At this stage of the course you are expected to have developed good understanding of the purpose of drawing spray diagrams as part of applying the SUDA process for solving a messy situation. A spray diagram is the first type of diagrams drawn in the sensing phase of the SUDA process of mess analysis, in order to summarize the main ideas of a case, or the main components/elements of a situation. Please pay attention to the conventions and make sure that the central topic and other subtopics are relevant, and do make sense to the reader. Go back to T552 (Diagramming) the appendix to refresh your memory about the conventions.
(b) This is your first attempt at drawing control model diagram. The task should not be challenging though. Refer to Concept file 04 section II Control. You need to draw a control model diagram to show how the selected inputs can reach the stated goal. You also need to illustrate clear, relevant, and non-overlapping inputs, clear and accurate transformation process and an output which is consistent with the goal. You also need to specify which organizational entity is in charge of assuming the role of each of the elements/components of the control model (i.e. actuator, sensor, and comparator). The parties in charge of performing each task within the control mechanism should be clearly identified. It is very important that your diagram is specific rather than generic.
(c) Here you need to practice your analytical skills to assess what is required. Remember to start with a good introduction in which you define the assessed topic before moving on to explaining your plan for working on the TMA. In the body you should move on to assess the causes of the problems faced by Toyota and the impact of the organizations structure, climate and decision making on its reaction to the problem. You also need to evaluate whether Toyota is a learning organization by relying on both theoretical principles and practical examples, and on the ideas presented in the assigned article.

Richard M. Locke, Cate Reavis, Diane Cameron
In November 2008, Shaws supermarkets sold a 10-ounce bag of Green Mountain Fair Trade certified coffee for $8.49. The bag which was adorned with the Fair Trade certified logo, did not explain the meaning of Fair Trade. Consumers were directed to a website or a phone number to get more information. However, the bag did say the following:
A good cup of coffee can change your day. A great cup of coffee can help change the world. By supporting farming communities, promoting sound environmental practices and sourcing only the highest quality beans we work to ensure that everyone who comes in contact with our coffee benefits. So while you appreciate the results in your cup, you can also rest assured that this coffee has had a positive impact on every person it has touched which to us makes these little beans a pretty big deal.
Q1. Apply the Hard Systems Method to this Situation case, including spry diagram and conceptual mapping in order to brainstorm, analyse and make suitable recommendations. Provide a detailed narrative explaining your thinking process. (1500 words) (50 marks)
Q2. Investigate further suitable approaches and tools that could be used to investigate, illustrate and make recommendation to solving problems. Please consult all your course materials and undertake relevant literature search. (400 words) (20 marks)
Q3. What are the main insights or new understandings that you gained from the application of HSM to the case study? (400 words) (20 marks)
