Answer:
The correct total time is nineteen (19) days instead of twenty-one days.
Explanation:
Given the analysis of time for the project in parenthesis, it is feasible to merge some of the activities together by carrying them out simultaneously.
For example:
In the course of arranging and confirming the training facility to use which will last for 3 days, the development of the training material that ought to last for 5 days is brought down to a 2 days work because the initial 3 days for arrangement becomes vacant pending the reply on the final day. This brings the total days from 8 to 5.
Other days remain thus:
• Send an e-mail message to all department managers (1 day)
• Print copies of handout (2 days)
• Develop a set of PowerPoint slides (5 days)
• Conduct a practice training session with the instructor (2 days)
• Conduct the user training sessions (4 days).
Hence, total days are as follow:
5 +1 + 2 + 5 + 2 + 4 = 19 days.
