PART B: Information Systems Development Questions (10% of 30%)
Please answer the following two questions – your answers should be recorded within the ISD_Answers
worksheet of the BISM‐Assign‐2019‐Sem‐2.xlsx file. Your answers should be concise (the approximate word
limit is shown below) and address the major points given in this specification.
1. (5% of the total 10%) You are a senior business analyst and your team has just be awarded a
contract for developing a customer relationship management (CRM) IS for a North American
corporate that operates 50 sales hubs across North American cities. You and your team are based in
Brisbane and specialize in providing cloud‐based CRM solutions. Under this model, your company
hosts the main CRM software, and your team then works with client companies to connect via web‐
based access to this CRM software. In overview, this very successful model provides sophisticated,
secure, economical CRM processing to client companies. This model, however, does not allow for
the development of bespoke solutions for clients – it is the client company that must adapt its
existing CRM processes to fit with your CRM processing model. This design characteristic is
consistently the major source of risk to a successful project outcome for your team.To date, your current team has completed many such projects – some via Waterfall, and some via
Scrum and Xp. Your team is now discussing the critical issue of requirements gathering for this
upcoming project. The question under discussion is: “Do we use Waterfall requirements gathering
or Scrum requirements gathering?” You have been asked by your project manager to put together a
concise (not exceeding 750 words) discussion paper (with diagrams included if considered
appropriate) for distribution within your team. The discussion paper must be structured as per the
following three major headings:
a) Requirements Gathering – an Overview (2%): This section should describe the most
important fundamentals of how and when requirements are obtained via Waterfall and
via Scrum and the type of documentation that is produced during these activities.
b) Customer Involvement (2%): This section should describe the options for customer
involvement in the project. This requires the identification of the responsibilities that the
client stakeholders must fully embrace, the difficulties posed by distance and time‐
difference between your team and the client company, and finally the identification of
the major risk that must be managed – with a suggestion of how this can be mitigated.
c) Recommendation (1%): This section must logically flow from the first two points and
address the central operational characteristics of the project. The recommendation may
be uniquely Waterfall, uniquely Scrum, or a combination of both.


2. (5% of the total 10%) Within your IS project from question 1 you are looking to use the Critical Path
Method (CPM) to analyse the range of activities/tasks you have identified. These tasks are shown in
the table below:

Task Characteristics
Task Name Predecessor Duration (Days)
A ‐ 5
B ‐ 4
C A 3
D A 4
E A 6
F B, C 4
G D 5
H D, E 6
I F 6
J H, G 4
You are now required to complete the following:

5 | Page

a) Define the terms concurrent tasks and dependent tasks. Which are concurrent tasks in the
above table, and why? (0.5%)
b) Define the term critical path. (0.5%)
c) Construct a graph of all tasks in this project. This graph should be in the same format as
shown in the ‘critical path’ video on Edge (a copy of this graph is shown below). You should
show all start and finish times for each task, and slack time for each task. You should clearly
show your actual critical path in red (as in the video and the example below). (4%)
