Draw the Gantt Chartarrow_forwardIn the model in Example 15.5, suppose bonuses and penalties are incurred for earliness or lateness. Specifically, suppose a bonus of $2000 is received if the project is completed within 60 days, an extra bonus of $1000 is received if the project is completed within 58 days, and a penalty of $1000 is incurred for every full day past a project completion of 64 days. (For example, if the project is completed in 66.7 days, the penalty is $2000—two full days late.) Modify the model appropriately, and then run the simulation to find the distribution of the net monetary outcome (negative if a penalty, positive if a bonus). What is the expected value of this net amount? What is the probability of a $3000 total bonus? What is the probability of a penalty of at least $4000? Example 15.5 LAN PROJECT WITH UNCERTAIN ACTIVITY TIMES We again analyze the LAN project from Example 15.1, but we now assume that the activity durations are uncertain, with given probability distributions.

- We classify projects as part of a project portfolio tracking. Suppose you have two projects, one of them is Large and another one is Medium. As a general rule, these two project-types follow different processes and have different approval levels. For example, a functional spec template for a Small project is not the same as for the Large project. There are total of six criteria to determine which project is Large. The following four criteria are very similar in both projects Level of experience of managrement team Engineering team familiarity with technology Number of function points (lines of code, story points, requirements, test cases) Number of people involved These two criteria are not similar First project will last for five years and cost a million dollars Second project will cost ten million dollars and last three months From the following three statements, select those ones that are true, Second project bears a highest risk and more likely to fail…arrow_forwardConsider the following project activities: Duration Activity Predecessor (DAY) 4 A A. 3 B C A 5 C 2 1 F G D, E 6.

Longer programs have a smaller margin of error. As a general rule, in a most basic scenario, the following two estimation methods should be used in this order: first, "analogy," and second, "decomposition." Precision with which estimates are communicated should be at least two orders of magnitude greater than the accuracy of these estimates. The logical order of initial project activities is to start with commitment then proceed into scheduling and finish with estimating. Estimates should never be provided by the people who will do the work that is being estimated. "Anchoring" is a prudent planning poker strategy, since it allows influencing all members of the scrum team to the greatest extent. The order, in which these two estimation methods most commonly used, is as follows: first "Monter Carlo Simulation", and second, "T-shirt sizing". The…arrow_forwardThe time estimates (in hours) for the activities of a PERT network are given below: a) Draw the project network b) Calculate standard deviation and variance of the project length(c) What is the percentage of confidence that the project will complete at least 4 weeks earlier thenexpected timearrow_forward
