ITM301 Principles of Information Systems in Business and Organization (DEC2016FT-1)
Module 1 Discussion Knowledge Sharing Tools
We live in an information age when infinite quantities of facts are widely available to anyone who can use a computer. We all now have the difficult task to compete in this information age where knowledge sharing within an organization could make a difference.
In your first posting, you are expected to provide one example of some kind of information technology tool that helps organizations share knowledge. Here you have a website that could give you some examples.http://www.kstoolkit.org/KSTools. Describe the knowledge sharing tool and discuss its benefits.
In your second posting, comment on the different knowledge sharing tools presented by your classmates and compare and contrast at least two with yours. Highlight the ability to share knowledge.
Module 2 Discussion Decision Making and Information Politics
As IT applications become more reutilized all across the board, one of the interesting features are the occasional employees who know more than the IT staff about some critical thing, often many of them. Communication between staff and IT then becomes much more complicated, because the balance of power between the two groups based on the dependence of staff on IT for help and support breaks down. While there is certainly nothing wrong with knowledge about technology it can lead to mixed messages, confused goals, feelings of lack of appreciation and lack of support, and generally less than effective maintenance of IT across-the-board. We certainly don't want to discourage our staff from acquiring technical knowledge, but we also don't want them to use that knowledge as a political weapon against IT's control of IT. Or do we? Maybe it's a good thing to have a level of stress between staff and IT if it serves to keep both groups on their toes and trying to outdo each other.
At any rate, user support isn't just looking after the least technological staff; increasingly, it's also providing for the power users, and those who would be power users. Have you had any experience with this knowledge-based tension between staff and IT? Even if you haven't, can you see how it could be a problem? What should we be doing about it?
We'll be interested in your ideas here.
(Note: Students are STRONGLY encouraged to respond to each other’s posts and to ask each other questions based on their posts. Obviously, the earliest posters will have to respond to the "seed" question to get the discussion started. But subsequent posters should read through all the previous responses and can respond to something in a previous post rather than the "seed" question. For example, if you have had a similar problem as a previous poster or disagree with a point that a previous poster made, you can respond directly to the previous poster and get credit for participating in the discussion.)
Module 3 Discussion Network Computing
Identify some commercial tools that allow users to conduct browsing, communication, and collaboration simultaneously. Explain why the topic of group work and its support has gotten increased attention.
Module 4 Discussion Mobile E-Commerce
Discuss the major limitations of mobile E-commerce. Which of them are likely to disappear? Why is the electronic job market so popular, especially among the high-tech professions?
Module 4 Reflective Discussion
Given the readings and assignments in the course, identify and briefly discuss two important concepts from this course that are applicable to your degree.
You can also include here any comments and suggestions about this course that you would like to highlight.
Thank you for your reflections! They help us all for continuous assessment and improvement of the learning experience.
Module 1 Discussion
In your own words, define an independent event and a dependent event. Provide an example of each type of event (i.e., using a deck of cards, computer programming, and/or business example). Include two additional examples for your peers to classify (but do not reveal the event). Review and respond to your peers by classifying their examples and providing a reason. Check the replies to see if they are accurate.
Module 2 Discussion
The mean salary is often used to describe the salaries of employees of a company. However, the median salary may be a better measure of the salaries in comparison to the mean. Research a career you are interested in and calculate the mean and median salaries using at least ten data points. Include the calculations and the data source(s). Which is the better measure of central tendency? Why? Review and respond to the comments posted by your peers and offer your insight on this topic. Do you agree or disagree with their selection? Why or why not?
Module 3 Discussion
The number of vacation days taken by the employees of a company is normally distributed with a mean of 14 days and a standard deviation of 3 days. For the next employee, what is the probability that the number of days of vacation taken is less than 10 days? What is the probability that the number of days of vacation taken is more than 21 days? Discuss the solutions and an explanation. Respond to your peers’ posts and offer your feedback on this topic.
Module 4 Discussion
Regression is a commonly used technique in business applications. What is the purpose of a regression analysis? Provide two examples of situations in business, or your field, when regression is used. Explain each situation in detail. Review your peers’ posts and identify the independent and dependent variables in their examples. Further the response by discussing why a regression analysis is useful in their applications.
Integration and Reflection
Upon successful completion of this module, the student will be able to satisfy the following outcomes:
- Discussion
- Reflect upon how the course improved your quantitative reasoning.
- Discuss how course content applies in personal and professional contexts.
Course Overview
As your study of this course content draws to a close, it is important to step back and reflect on new levels of understanding, skills, and knowledge that you developed as a result of your efforts throughout this course. It is particularly important to reflect on the course outcomes (what you were intended to learn in this course).

- Choose the most appropriate measure of central tendency for a particular set of data (Module 2).
- Create and interpret information from a box plot (Module 2).
- Describe the information provided by the Standard Deviation (Module 3).
- Use the Standard Deviation to calculate the percentage of occurrence of a variable either above or below a particular value (Module 3).
- Describe a normal distribution as evidenced by a bell-shaped curve (Module 3).
- Prepare a distribution table from a set of data (Module 3).
- Calculate the variance (Module 3).
- Define sampling methods and terminology (Module 4).
