QUESTION FOUR

The following information is provided for a project that you are working on:

Required:

$4\mathrm{.}1$ Construct the network diagram $($activity on node$).$

$4\mathrm{.}2$ Identify the paths of the network and find the critical path.

$4\mathrm{.}3$ When the Airbus A$380$ was launched in $2007,$ much was expected of the airplane, but just $10$ years later, they were being sold for no more than spare parts. The expected game$-$changer led to Airbus struggling to secure deals with airlines. The A$380$ was expensive to produce and Airbus's Project teams didn't communicate and used different computer drawing programs. That mistake alone cost $\backslash (\backslash$$ $6\backslash )$ billion. Furthermore, the second$-$hand market was non$-$existent because the planes were simply too big for any airline to make back their invested money.

If you were the Project Manager responsible for the construction of the A$380,$ evaluate the factors that could have contributed to its success.
