The assignment here is to identify some interesting claim or fact or insight from each of two sources, and to then write something explaining a connection between these.

(1) The first source is the Keneally book (preferably from chs. 14-16 (but it’s acceptable to be from chs. 11-16)) and

(2) The second source is to be the World Food Programme website http://www.wfp.org/

• First, from the Keneally book, locate an interesting or significant claim or fact or insight.
• Second, find some claim or fact or insight made on the WFP website which is interesting or significant, given what you’ve learned in the course so far.
• State these two items as precisely and clearly as you can, clarifying why they are significant.
• Then describe or explain some interesting connection between these two items.(Obviously, you can’t choose these at random, but need to choose them with this potential comparison or connection in mind.)

(Note: ways of being “interesting or significant” can include a number of different things: e.g., being surprising, being controversial, or being insightful in that they let us see things in a new light which may be useful. One of the points might provide some explanation for the other, or it might in fact cast doubt of the reasonableness of the other. Note that you should be sure to be showing your understanding of the Keneally book or the themes of the course as a whole so far.

You would do well to show that you have an understanding of what Keneally is trying to say, and also to show that you have searched thoughtfully through the WFP website.

Quotations, if you have them, should not be long, and they don’t count toward the word count.

Citations: For what you take from the Keneally book, please cite the page number (Keneally, p. X).In the case of the website, cite by cutting and pasting the link to the specific page, and indicating the “heading” if this is useful.

GENERAL INSTRUCTIONS (see syllabus):

Recall from the syllabus that these responses should range between 300 and 400 words.(Write your response in a word processor before putting it online to get an accurate word count). Copied or quoted material will not count toward the word limit on discussion posts (e.g. If you copy a block of text and put it a post as a quote, you still need to write at least 300 words that is your own work.)

As noted on the syllabus, these will be graded according to the following scale:

• Exceeds Expectations: A post that is on topic and that makes an especially perceptive and constructive set of observations, comments or critiques: 40 Points.
• Achieves Expectations well: A post that is clear, thoughtful, on topic and clearly relevant to the topic at hand: 38 points.
• Good: A post that is clearly on topic: 35 points.
• Satisfactory: A post that is “in the ballpark”, but not quite sufficiently clear and/or relevant. 30 points.
• Minimally Acceptable: At least 300 words and basically coherent (and not shown to involve plagiarism (see “Academic Integrity”)). 20 points
• Otherwise: Unacceptable. 0 points

Q2 The analogy method of estimating is often used to produce broad-brush estimates at the start of a project. Why is this method particularly suited to this application?


Q3 The analysis effort and programming methods both rest on the principle of extrapolating the total development effort from detailed estimates of one phase of the project. Describe the approach taken in each of these methods and show in what circumstances each might best be employed.



Q4 The Delphi technique aims to achieve a consensus estimate from the efforts of a number of estimators. How is this achieved and what is the advantage of the Delphi technique over, for example, a round-table discussion?

Q1 How would you assess the importance of sales skills to a project manager? Are they, in your view, increasing or decreasing in importance? Why do you think there is this change? Is it more important to understand selling or buying?


Q2 Persuading someone to buy is a complex process. Why is this? Is the process inherently complex, or is it because so many people are involved?


Q3 If selling is an ‘asking process’, how could you use it to help you sell some extra functionality to a system under development?

Chapter 18 Managing stakeholders


Q1 Stakeholders have different interests or ‘stakes’ in a project. How can you determine where to put your management effort?

Chapter 21 Performance management


Q1 You are dissatisfied with the general level of performance of one of your team. The quality of work is below your expectations. How will you deal with this?


Q2 A member of your team exhibits disruptive behaviour. Her work is good but she is not a team player. The consequences are that she does not contribute to team effort and her colleagues find her difficult to work with; the project team secretary has refused to work with her at all. How could this serious problem have arisen? What can be done now?

How could the project manager influence the working environment of such a team so as to get the best out of them? What are the behaviours that they could exhibit that would have an effect on the working style of the project team?


Q2 Conflict and stress arise naturally in IS project teams. Some people argue that a little of both is useful, but everyone agrees that too much is destructive. How could you organise your project team to minimise the destructive effect of conflict and stress?

Accepted characters: numbers, decimal point markers (period or comma), sign indicators (-), spaces (e.g., as thousands separator, 5 000), “E” or “e” (used in scientific notation). NOTE: For scientific notation, a period MUST be used as the decimal point marker.
Complex numbers should be in the form (a + bi) where “a” and “b” need to have explicitly stated values.
For example: {1+1i} is valid whereas {1+i} is not. {0+9i} is valid whereas {9i} is not.

Scores on a mathematics examination appear to follow a normal distribution with mean of 65 and standard deviation of 15. The instructor wishes to give a grade of “C” to students scoring between the 60th and 70th percentiles on the exam.

What score represents the 60th percentile score on the mathematics exam? Place your answer in the blank, rounded to a whole number. For example, 62 would be a legitimate entry.
