The activities illustrated in Table $3$ represent is a $3-$week scrum sprint to code the system$$s ETA

$($estimated time of arrival$)$ functionality if the project stakeholder decide to pursue Project T$.$

Table $3.$ The activities of coding ETA with associated estimated duration and predecessors.

Activity Description

Duration

$($days$)$ Predecessor

A

Design the UI for order placement, order

status, and delivery tracking $5$

B

Document APIs $($application programming

interface$),$ algorithms and overall system $22$ A

C

Implement UI components for placing orders

and receiving ETA. $3$ A

D

updates using WebSockets or similar

technologies $1$ C

F

for delivery $3$ D

G Integrate real$-$time traffic data to adjust ETA $5$ F$,$ E

H

Use machine learning to predict more accurate

ETAs based on historical data $2$ G

I

Write and execute unit tests for individual

components $2$ G

J

Test the integration between different

components, including APIs and third$-$party

services $2$ H

K

Conduct testing sessions with stakeholders to

ensure the system meets their requirements $3$ J$,$ I

L

load conditions to ensure it can handle high

volumes of orders and tracking data $2$ K

$3\mathrm{.}2.$ Identify the critical path. $(2)$

$3\mathrm{.}3.$ Identify the activities with slack. $(2)$

$3\mathrm{.}4.$ Identify two activities in a mandatory dependency relationship. Explain what a mandatory

dependency is and why the identified activities have a mandatory dependency. $(4)$
