3.Prepare a Gantt chart for the tasks shown for question 2. (This can be hand drawn if you have no software to make it, and then you can take a picture of your drawing and included it in this document as an image).

4. Determine the critical path for the tasks shown for question 2.

5.  Your company is planning to launch a new IT project starting July 1 that will last one year. You estimate that you will need one full-time project manager, two full-time business analysts for the first six months, two full-time senior systems analysts for the whole year, four programmers for the months of February-May, and one full-time technical writer for the last three months. Create a stacked column chart using Excel that shows resources by month. Provide appropriate titles, axes labels, and legends.

6.  Take the MBTI. There are several websites you can use: www.humanmetrics.com, www.personalitytype.com, and www.kiersey.com. Write a one-page summary discussing your MBTI type and its opposite MBTI type. For example, if you are an INTJ, then its opposite is ESFP. What challenges would you see working with this person on a project? What you think about the MBTI as a team-building tool?

7.  Your IT consulting company is trying to decide which of four projects to bid. Information on each is in the table below. Assume that all up-front investments are not recovered, so they are shown as negative profits. Draw a diagram and calculate the expected monetary value (EMV) for each project. Write a paragraph explaining which project(s) you would choose to bid.

8.  Your company has a technical support line for customers to call. Create a Pareto diagram based on the information in the following table. Create a spreadsheet using these data. List the most frequent complaint first. Then add a column labeled “% of Total” and another labeled “Cumulative %”. Then enter formulas to calculate these items. Then use the Excel Chart Wizard to create a Pareto diagram based on the data. Use the Line – Column on 2 Axis custom type chart so that your resulting chart looks similar to the one in Figure 8-1.
