Draw an activity network using either activity$-$on$-$node or activity$-$on$-$arrow network

conventions for each of the following projects:

Redecorating a room;

Choosing and purchasing a desktop computer;

Organizing and carrying out a survey of users opinions of an information system.

The precise nature of the networks drawn up will depend on the particular approaches taken.

There are no sole correct answers, but plenty of scope for discussion
