Question 1. (January 2002: Risk) (a) How can risk be managed within a project? Use a diagram to illustrate your answer.
(15 Marks)
(b) A new MS Access/Visual Basic system for a chemical development company will take 1 week
for requirements capture, 7 weeks for development and 3 weeks for acceptance testing. There
is an 80% chance that this is insufficient because the MS Access specialist may be required to
support a different project of higher priority. If this were to happen the 7 weeks development
would extend to 10 weeks, at a cost of 6 person-weeks.
(i) Draw a diagram to demonstrate the impact of the risk, and calculate how the project
plan would need to be modified in terms of additional effort and duration. (8 Marks)
(ii) A two-week training course on Advanced MS Access could be booked and would
reduce the risk to 50% at a cost of 4 person-weeks. The training could take place in
parallel with the requirements capture. Draw a diagram to show the containment
action and the recalculate the revised impact on effort and duration.
(8 Marks)
(iii) Should the training course be booked? Justify your answer. (2 Marks)
Question 2. (January 2002: DCF/NPV) Barter and Haggle are a printing company producing business cards, small numbers of books and
greetings cards; they wish to update their computer system to deal with customer accounts while
retaining their traditional printing facilities. Barter and Haggle have examined the options open to
them, and have narrowed the choice to the following:
Option 1 12 workstations purchased from Linkway Computers at £1200 per machine
Option 2 12 workstations rented from Hiram Safely at £200 per machine per annum in the first
year, rising by £25 per annum per machine for each subsequent year.
Whichever option is chosen, insurance will need to be paid at 15% per machine per annum of the
purchase price. Barter and Haggle plan to replace the equipment after seven years, and have negotiated
with Hiram Safely that they will be paid £250 per machine if they renew a new rental option at that time
with that company; no similar deal has been negotiated with Linkway Computers. When you undertake
the cost calculations, you will also need to take into account any income generated from the collection
of the workstations.
You are required to calculate the apparent costs, and the Net Present Value for:
Option 1 (purchase) (13 marks)
Option 2 (rental) (16 marks)
given the Discounted Cash Flow rates of 12% and 15% below.
Which option would you recommend, and why? (4 marks)

DCF 12% 1.0 .89 .80 .71 .64 .57 .51 .45 .40
DCF 15% 1.0 .87 .76 .66 .57 .50 .43 .38 .33
Question 4. (January 2002: Motivation, STEEP & SMART)
(a) Outline the concepts of Herzberg's Motivation-Hygiene Theory and Maslow's Hierarchy of Needs.
You should use diagrams to illustrate your answer. How do these two theories correspond?
(17 marks)
(b) In the context of project management, explain what is meant by the acronyms "STEEP" and
"SMART". Give an example of each of the STEEP characteristics, and one example fulfilling all
the SMART criteria. (16 marks)

Question 2. (May 2002: Risk) (a) Explain with the aid of a diagram one possible way of managing risks within a project.
(15 Marks)
(b) A new Java and Oracle based system for a bank will take 2 weeks for requirements capture, 8
weeks for development and 2 weeks for acceptance testing. There is a 75% chance that this will be
insufficient because the Oracle developer may be required to support a different project of higher
priority. If this were to happen the 8 weeks of development time would extend to 12 weeks, at a cost of
8 person-weeks.
(i) Draw a diagram to demonstrate the impact of the risk, and calculate how the project plan
would need to be modified in terms of additional effort and duration. (8 Marks)
(ii) The Java developer could attend a two-week Oracle training course before requirements
capture. This would reduce the risk to 25% at a cost of 2 person-weeks. Draw a diagram to
show the containment action and recalculate the revised impact on effort and duration.
(8 Marks)
(iii) Should the training course be booked? Please explain your answer. (2 Marks)
Question 3. (May 2002: Gantt charts) Consider the following activities, scheduled as a project that starts on Friday 24 May 2002. Note that
Saturday and Sunday are not working days, and that Monday 3 June and Tuesday 4 June are Bank
Holidays (and are therefore not working days).

There are dependencies between certain activities, as given below:
Activity B cannot start until Activity A has finished
Activity D cannot start until Activity C has finished
For technical reasons, there must be 3 consecutive working days between the end of Activity C
and the start of Activity E (e.g. if the last day Activity C runs is a Monday, Activity E could not
start until Friday, but if the last day Activity C runs is a Friday, Activity E could not start before
the following Thursday)
Activity F cannot start until Activity E has finished
(a) Draw a Gantt chart showing each activity for this project. How many working days does the
project take, and when does the project finish? (11 marks)
(b) If additional resources are made available so that Activity C starts 1 working day earlier and
its duration is reduced from 5 days to 4, what effect does this have on the project? Draw a Gantt chart
to illustrate your answer. (10 marks)
(c) If Activity C is delayed by 1 working day, based on the original start plan, what effect does
this have on the project? Use a Gantt chart to illustrate your answer. (12 marks)
Question 4. (May 2002: Belbin’s team roles) (a) Specify each of the nine team roles identified by Belbin, highlighting two strengths and one
allowable weakness in each case. You may give your answer in tabular format or as a sequence of
paragraphs. (18 marks)
(b) Comment on the balance between the strengths and allowable weaknesses for each team role,
and indicate how strengths and weaknesses may compensate for each other across the team
roles. (15 marks)

Now that you have finished the calculations for the network diagram, Alex has asked you to carry out
the following tasks:
(c) What are the staff resources used each day for the project? (12 marks)
(d) What is the peak day for staff resources? What would the effect of starting Activity E four
days later than the EET? (3 marks)
Question 2. (January 2003: Risk) (a) A new MS Access/Visual Basic development for a financial services company will require 2
weeks for the Feasibility Study, 3 weeks for analysis, 10 weeks for prototyping and 2 weeks for
implementation. There is a 70% chance that this is insufficient because the MS Access specialist may be
required to support a different project of higher priority. If this were to happen the 10 weeks
prototyping would extend to 13 weeks with an additional 5 person-weeks.
(i) Draw a diagram to demonstrate the impact of the risk, and calculate how the project
plan would need to be modified in terms of additional effort and duration. (8 Marks)
(ii) A 4 week training course could be booked and would reduce the risk to 30%
requiring an additional 4 person-weeks. The training could take place in parallel with
the Feasibility Study. Draw a diagram to show the containment action and the
recalculate the revised impact on effort and duration. (8 Marks)
(iii) Should the training course be booked? Please explain your answer. (5 Marks)
(b) This question refers to figure 1 and figure 2, shown on the following page.

There are dependencies between certain activities, as given below:
Each activity must start as soon as possible after any preceding activities, given the following
constraints
Activity C cannot start until Activity A has finished
Activity A and Activity D must start at the same time
For technical reasons, there must be 3 consecutive working days between the end of Activity C and
the start of Activity E (e.g. if the last day Activity C runs is a Monday, Activity E could not start
until Friday, leaving Tuesday, Wednesday and Thursday as the 3 consecutive working days, but if
the last day Activity C runs is a Friday, Activity E could not start before the following Thursday,
leaving Monday, Tuesday and Wednesday as the 3 consecutive working days)
Activity F cannot start until Activity E has finished
(a) Draw a Gantt chart showing each activity for this project. How many working days does the
project take, and when does the project end (i.e. what is the first working day after all activities are
finished)? (11 marks)
(b) If additional resources are made available so that Activity B starts 1 working day earlier and
its duration is reduced from 6 days to 4, what effect does this have on the project? How many working
days does the project now take, and when does the project end (i.e. what is the first working day after
all activities are finished)? This change to the project will cost an additional £500; justify your reasons
as to whether you would recommend this proposed change. Draw a full Gantt chart to illustrate your
answer. (11 marks)

Question 2. (May 2003: Risk) (a) Describe the four stages of the risk management process. (15 Marks)
(b) A new Java/Oracle system for a sales company will take 3 weeks for requirements capture, 10
weeks for development and 5 weeks for acceptance testing. There is an 85% chance that this is
insufficient because Oracle is unknown to the developers. This would result in a delay of 5 weeks in
development, at a cost of 12 person-weeks.
(i) Draw a diagram to demonstrate the impact of the risk, and calculate how the project plan
would need to be modified in terms of additional effort and duration. (8 Marks)
(ii) Formal training before requirements capture would reduce this risk to 25% at a cost of 5
person-weeks. The course lasts 1 week. Draw a diagram to show the containment action and
then recalculate the revised impact on effort and duration. (8 Marks)
(iii) Should the training course be booked? Please explain your answer. (2 Marks)
Question 3. (May 2003: DCF/NPV) Walter Wall Carpets, a company supplying and fitting carpets and soft furnishings, wish to upgrade
their computing facilities. The company uses its computers for processing customer orders and
invoices, stock control and supplier records. Walter Wall Carpets have considered the available
options, and need to decide between the following two:
Option 1: 10 workstations rented at £150 per machine per annum in the first year,
rising by £15 per machine per annum each year from PC Surprise PLC.
Option 2: 10 workstations rented at a constant rate of £185 per machine per annum
from IT4ALL.
Whichever option is chosen, insurance will need to be paid at a rate of £10 per machine per annum.
Walter Wall Carpets plan to replace the equipment after 6 years, and do not expect to receive any
refund from the supplier at this time.
Given the Discounted Cash Flow rates of 5 % and 8% (see the formula sheet), you are asked to
calculate the apparent costs, and the Net Present Value for:
Option 1 (from PC Surprise) (15 marks)
Option 2 (from IT4ALL) (15 marks)
Which option would you recommend, and why? (3 marks)

Question 4. (May 2003: Leadership and motivation) You have been appointed as project manager by Candle & Carver Ltd, a traditional furniture
manufacturer, to design and develop a customer database system. You have outlined your project
plans, which include training sessions for Candle & Carver's staff on using the new system. Barry
Bullimore, Customer Services Manager, is in charge of the team of end users. He says he doesn't see
the need for staff training. “If staff can't find out how to use the system themselves, we'll just appoint
new staff who can,” says Barry. Candle & Carver acknowledge that they have a problem retaining staff
in the customer services department.
(a) Identify and describe each of the 6 leadership styles as discussed by Burke (1999). Specify which
of these styles appears to be closest to Barry Bullimore's approach to leadership, and explain why. You
may also refer to other styles of leadership in your answer. (18 marks)
(b) The senior management of Candle & Carver Ltd have asked you to make a presentation lasting
20 to 30 minutes dealing with aspects of staff motivation. Barry Bullimore will be one of eight
departmental managers attending your presentation. Identify and describe the issues that you would
raise at this presentation. (15 marks)
Question 5. (May 2003: Network diagrams, CPM) You are the Project Manager for a team working on the development of a new library system. You
have specified the duration in days for each activity and constructed the network diagram for the
project. Bob Bodgett, one of your project team, has been assigned to calculate the Earliest and Latest
Event Times, and identify the critical path. Bob is not sure that the Earliest Event Times (EET) and
Latest Event Times (LET) he has calculated are correct. Bob’s EETs and LETs are shown in Table II
and the network diagram II below.
(a) Using Table I and/or Network Diagram I below, perform your own calculations for the Earliest
Event Time (EET), the Latest Event Time (LET) at the start of each activity, and the float or
slack associated with each activity. (10 marks)
(b) Identify the critical path based on your calculations. (4 Marks)
You may assume that the times are in days, the network diagram is correct in that the activities are in
the right order, and the duration is accurate in each case.
Note: You may enter the results of your calculations in Table I or on Network Diagram I and attach

Question 1. (January 2004: Risk) (a) Describe two different models of risk management. You should illustrate your answer with
diagrams. (Diagrams alone are not sufficient). What are the key features common to both the
models you have chosen? (15 Marks)
(b) A new Visual Basic/MS Access system for a sales company will take 5 weeks for requirements
capture, 8 weeks for development and 4 weeks for acceptance testing. There is a 75% chance that this
will be insufficient because the developers are not experienced in Visual Basic. This would result in a
delay of 3 weeks, with an additional 12 person-weeks involved in development.
(i) Draw a diagram to demonstrate the impact of the risk, and calculate the additional effort
and duration that would need to be accommodated in the project plan. (8 Marks)
(ii) A 1-week training course in parallel with requirements capture would reduce this risk to
20%, but it would involve 5 person-weeks. Draw a diagram to show the containment action
and then calculate the revised impact on effort and duration. (8 Marks)
(iii) Based on your calculations above, should the training course be booked? Please explain
your answer. (2 Marks)
Question 2. (January 2004: DCF/NPV) Repaint@Leisure, an interior design company, sells wallpaper, paint and associated home decorating
products. They also offer a competitive interior design service for their clients. The company now
wishes to upgrade its equipment to include the provision of notebook PCs for staff visiting clients in the
homes. The company uses its computers for processing customer orders and invoices, stock control,
supplier records, client appointments and interior design. Repaint@Leisure has considered the
available options, and need to decide between the following two:
Option 1: to purchase 5 PC workstations (£1100 each) and 5 colour printers (£275
each) for use in their offices, and rent 5 PC notebooks (£120 each per annum) for use by their
interior design consultants. The supplier is Gladiator Equipment.
Option 2: to rent 10 PC notebook PCs (£180 each per annum) and purchase 5 colour
printers (£275 each) from X-Calibre.
Whichever option is chosen, insurance will need to be paid at a rate of £10 per machine per annum,
whether it is a workstation or a notebook; no insurance premium is paid on the printers.

Question 4. (January 2004: Gantt charts) Consider the following activities, which are part of a project scheduled to start on Tuesday 30 March
2004. Note that Saturday and Sunday are not working days, and that Friday 9 April, Monday 12 April
and Monday 3 May 2004 are Bank Holidays (and therefore not working days). Only working days are
numbered; you should number these on your Gantt charts.
Activity Start Day Duration (in working days)
A 0 3
B 1 3
C 4 4
D 12 3
E 15 6
F 22 3
You should note that all activities must start as soon as possible; you should also take into account the
dependencies between certain activities described below:
Activity B must start one day after Activity A has started;
Activity C cannot start until both Activity A and Activity B have finished;
Activity C must run on 4 consecutive working days (not split over a weekend);
There must be a gap of two working days (which can be split over a weekend) between the end of
Activity C and the start of Activity D;
Activity D must run on 3 consecutive working days (not split over a weekend);
Activity D must have finished before Activity E can start;
Activity E must have finished before Activity F can start;
Activity F must run on 3 consecutive working days (not split over a weekend).
(a) Draw one Gantt chart showing each activity for this project. (9 marks)
(i) How many working days does the project take, and when does the project finish (i.e.
what is the first working day when all activities have been completed)? (2 marks)
(b) What happens if Activity B overruns by one day? Draw a complete Gantt chart to illustrate your
answer. (6 marks)
(i) How many working days does the project now take, and when does the project finish?
Comment on your results. (5 marks)
(c) The reallocation of a team member to Activity C, based on the original plan, means that this activity
now takes 3 working days rather than 4, but Activity E now takes 7 working days rather than 6 as a
result. What is the effect of this on the project as a whole? Draw a complete Gantt chart to illustrate
your answer. (6 marks)
(i) How many working days does the project now take, and when does the project finish?
Comment on your results. (5 marks)
Question 5. (January 2004: Network diagrams, CPM) Consider the following scenario.
“You work for a company that organises conferences for clients, and you are the project manager for a
team organising a two-day conference on the risk posed by computer viruses. The client is a well-
known software developer, and expects delegates to attend from other companies, universities, as well
as private individuals. You have been given a shortlist of names of possible speakers for the
conference. The speakers need to be invited to the event, and will then require both travel
arrangements and hotel facilities to be organised (at the same time) for them. As project manager, you
will also need to investigate possible venues for the conference, and then hire the most appropriate
one. When the venue has been hired, and the speakers have been organised (including their hotel and
travel arrangements), it will be possible to advertise the conference, and then take bookings from
delegates who wish to attend. When the venue has been hired, you will need to evaluate whether it is
more cost-effective to buy or rent microphones for the speakers, and then acquire microphones for the
event. After the conference has taken place, you will need to arrange payment of expenses for the
invited speakers.”

(a) Construct a network diagram for the 10 activities that you have identified in (a) above, using the
Activity-on-Arrow convention. You must indicate which activities have to occur in sequence
(dependencies), and which can run in parallel, but you do not need to consider the start time or
duration of each activity. You may wish to indicate the predecessor of each activity in Table I
above, or by a description to accompany your network diagram. (13 marks)
(b) You are also working on another conference for a different client. You have specified the duration
in days for each activity and constructed the network diagram for the project.
(i) Using Table II and/or Network Diagram I below, calculate the Earliest Event Time
(EET) and the Latest Event Time (LET) for the start of each activity, and the
float/slack associated with each activity. (10 marks)
(ii) Identify the critical path based on your calculations. (5 Marks)
You may assume that the times are in days, the network diagram is correct in that the activities are in
the right order, and the duration is accurate in each case.
Note: You may enter the results of your calculations in Table II or on Network Diagram I and attach
these pages to your answer booklet. Remember to add your student number, examination hall and

Question 1. (May 2004: Risk) (a) In the context of risk analysis and management, what is meant by each of the following the terms?
i. risk (6 marks)
ii. contingency plan (3 marks)
iii. containment action (3 marks)
iv. tracker (3 marks)
(b) A new web-based holiday reservation system for a travel agency will take 3.5 weeks for
requirements capture, 10 weeks for development and 5 weeks for acceptance testing. There is a 65%
chance that the time allowed for development will not be sufficient because the developers are not
experienced in Java. This would result in a delay of 4 weeks, with an additional 9 person-weeks
involved in development.
i. Draw a diagram to demonstrate the impact of the risk, and calculate the additional effort and
duration that would need to be accommodated in the project plan. (8 Marks)
ii. A 2-week training course before requirements capture would reduce this risk to 10%, but it
would involve an additional 3 person-weeks. Draw a diagram to illustrate the inclusion of the
training course, and then calculate the revised impact on effort and duration. (8 Marks)
iii. Based on your calculations above, should the training course be booked? Please explain your
answer. (2 Marks)
Question 2. (May 2004: DCF/NPV) Carrie Vann, a new car valet company, offers a competitive car-cleaning service for their clients. The
company wishes to acquire notebook PCs for use by car valet staff to organise their appointments while
they are travelling between clients or in the office. The company also plans to acquire PC workstations
for use at head office for booking customer appointments, issuing invoices and receipts, stock control
and supplier details. Carrie Vann has considered a range of options, and needs to decide between the
following two:
Option 1: to purchase 5 PC workstations (£975 each) for use at head office, and rent 5
PC notebooks (£120 each per annum) for use by their car valet staff. The supplier is Camel
Trading.
Option 2: to rent 5 PC workstations (£190 per annum) for use at head office, and rent 5
PC notebook PCs (£180 each per annum) for use by their car valet staff. The supplier is Dune
Computing.
Whichever option is chosen, insurance will need to be paid at a rate of £8 per machine per annum,
whether it is a workstation or a notebook. Carrie Vann plans to replace the equipment after 4 years, and
there will be a collection charge of £20 for each purchased machine for the disposal of equipment in the
fifth year. There is no collection charge for rented equipment.
(a) Given the Discounted Cash Flow rates of 3% and 6% (see the separate formula sheet), you are asked
to calculate the apparent costs (giving the component parts of your calculations in full) and the Net
Present Value for:
i. Option 1 (from Camel Trading) (15 marks)
ii. Option 2 (from Dune Computing) (14 marks)
(b) Which option would you recommend, and why? (4 marks)

Question 5. (May 2004: Network diagrams, CPM) Consider the following scenario.
“You work for a company that organises exhibitions, and you are the project manager for a team
organising a two-day exhibition on computer graphics and animation. You are expecting visitors to
attend from other companies, universities, as well as private individuals.
You have a list of companies who wish to contribute by displaying their hardware and software at the
exhibition. Representatives from these companies will need to be invited to the event, and they will
then require both travel arrangements as well as hotel facilities to be organised for them (these last
two activities should be carried out at the same time).
As project manager, you will also need to investigate possible halls for the exhibition, and then hire the
most appropriate one. After the hall has been hired, and the company representatives have been
organised (including their hotel and travel arrangements), it will be possible to advertise the
exhibition. After this, you will need to arrange for the exhibition guide to be printed. At the same time
as advertising the exhibition and printing the exhibition guide, you will need to rent the display stands,
and when they have been delivered you will need to erect them in the exhibition hall.
After the exhibition has taken place, you will need to calculate the income generated by visitors to the
exhibition.”
