QUESTION $1$

$1\mathrm{.}1$ Based on the diagram below which use case diagram representing a system used

to plan a seminar.

Figure $1\mathrm{.}1$: Case diagram

As an information system representative,

How was Figure $1\mathrm{.}1$ created for the different levels of the case diagram. $(4)$

$$ Hint: Follow the method created by the expect Alistair Cockburn

$1\mathrm{.}2$ Discuss the three stages of developing a case scenario, discuss according to the

following three stages:

$-$ Identification and initiation.

$-$ Steps performed.

$-$ Conditions, assumptions, and questions.

$1\mathrm{.}2\mathrm{.}1$ Discuss in detail the first two stages of the three$-$case scenario. $(6)$

$1\mathrm{.}2\mathrm{.}2$ Outline the elements of third area of the use case that need to be considered by

the data analyst in the organisation. $(9)$

$1\mathrm{.}3$ Discuss the important step that an analysist needs to consider when analysing

input and output form. $(6)$

QUESTION $2$

$2\mathrm{.}1$ How would you categorise a larger collection of project information? $(4)$

$2\mathrm{.}2$ Develop a context$-$level data flow diagram for the order processing system at your

organisation. $(5)$

$2\mathrm{.}3$ Develop a detailed data flow diagram for the Unisa student registration process.

$(6)$

$2\mathrm{.}4$ Identify the crucial values to the agile approach and provide your understanding of

each value. $(4)$

QUESTION $3$

$3\mathrm{.}1$ There are seven concrete observable elements of STROBE to support the new

development of projects. As information analyst, construct the questions for

investigating the following elements? $(8)$

$-$ Office location

$-$ Desk placement

$-$ Stationary equipment

$-$ Office lighting and colour

Hint: Ask at least $2$ relevant questions as an analyst for each observable element.

$3\mathrm{.}2$ Provide the justification if prototyping is necessary or not and advantages of

prototyping the newly developed project before implementing it$.$ Include the three main

ways a user can be of help in prototyping. $(5)$

$3\mathrm{.}3$ How would you justify the dependence of the successful prototyping? $(2)$

$3\mathrm{.}4$ Discuss the agile principles listed below to convince the management of the newly

proposed system that your department wants to implement. In your discussion give an

introduction to service that these principles will be applied to$.$

Principles to be discussed:

$1.$ Satisfy the customer through delivery of working software.

$2.$ Embrace change, even if introduced late in development.

$3.$ Continue to deliver functioning software incrementally and frequently.

$4.$ Encourage customers and analysts to work together daily.

$5.$ Trust motivated individuals to get the job done.

QUESTION $4$

$4\mathrm{.}1$ Articulate three key elements of project feasibility and provide an example of each.

$(6)$

$4\mathrm{.}2$ University of South Africa is conducting a project withing its premises to ensure

teaching and learning takes place smoothly. During the process of hiring people to

work in the team, offered you a project leader position and you will earn R$35000$ every

month with a $21\%$ tax deduction. Planned value $($PV$)$ is simply R$80000.$ To calculate

the planned value $($PV$)$ we need to multiply the earned value $($EV$)$ by the percentage

of the project that is $95\%$ complete. If the actual cost $($AC$)$ is R$99120,$ how would you

determine the following?

a$)$ The earned value $($EV$)(3)$

b$)$ The cost variance of that month. $(3)$

c$)$ Cost performance index $(3)$

d$)$ Discuss the significance of the calculated cost performance index to the

stakeholders. $(1)$
