PLEASE HELP ON BELOW QUESTION ON SOFTWARE PROJECT MANAGEMENT

-------------------------------------------------------------------------------------------------------------------------------------------------

"The shortest total length of a project is determined by the longest path through a network diagram." Explain the concept behind this statement [3 marks] The table below shows the breakdown structure for the second sprint of a software development project. Tasks Dependency Duration (days) 8 A A 5 B 6 D 8 BH D, F CI 9 3 E F G H I 7 8 G H 9 J K L 2 J J 3 (i) Create an Activity on Node (AON) network activity diagram for the Project. Your AON should include the following elements: the total duration of the project, its early start time, early finish time, late start time, late finish time, Slack for each activity. [8 marks] Indicate the project's critical path and total duration. Given the following COCOMO constants table: Organic Semi-detached Embedded 2.4 3.0 3.6 b 1.04 1.12 1.2 C 2.5 2.5 2.5 d 0.37 0.35 0.32 Assume that you are to use COCOMO to estimate a project. The project is a rather simple stand-alone utility for a computer running Linux. A person in your team who has done this before estimates the total lines of code to be 36,000. The program must be written in Python. All the rest of the members on your team are experienced. The team is very fluent in Linux and Python. All other factors can be considered to be nominal Using basic COCOMO, estimate the following for this project: the man-months required, [3 marks] the development time, [3 marks] (iii) the number of developers to be allocated for this project.

Your AON should include the following elements: each activity Time Estimate (TE) (rounding to the nearest integer), the total duration of the project its early start time early finish time late start time late finish time Slack for each activity [8 marks] . Indicate the project's critical path and total duration. [1 marks] Based on the Table from part (f) state two resource allocation problems that the project manager may encounter. [2x2 marks]
