You are in charge of a project. Your team has determined that there are 7 activities to be completed. Here are the activities, the time to complete the activity and the immediate predecessor of the activity. Using this data 1) construct a Gantt Chart, 2) determine the time it will take to complete the project, 3) You are monitoring the progress of this project and discover that activity C is in danger of taking longer than planned due to funding issues. What options do you have to get the project back on track?

A company is willing to develop their rocket before the end of current financial
year which is now 28 weeks away. The chief engineer of the company has
decided to use PERT technique in order to plan, schedule and control program
of development for the data given in table below.
What is the probability that the program will be completed by the end of the
current financial year? (all durations are in weeks).

- Mangement Project management is a discipline that involves planning, organizing, and overseeing the execution of a project from initiation to completion. It encompasses defining project goals, outlining tasks, allocating resources, and managing budgets and timelines. A successful project manager must possess strong leadership skills, effective communication, and the ability to mitigate risks and solve problems efficiently. Collaboration among team members is crucial, as is the flexibility to adapt to unexpected challenges that may arise during the project lifecycle. Continuous monitoring and evaluation ensure that the project stays on track, meeting objectives and delivering value to stakeholders. Question: How can project managers encourage effective collaboration and communication among team members to ensure the successful and timely completion of a project?arrow_forwardProject Scope Management Khan, (2006) (see below) states that, "Managing the scope of a project is the most important function of a project manager ... Effective scope management of a project also ensures the success of key completion areas, including time, cost, and quality. Project scope management can be further subdivided into its components which include: project initiation, scope planning, scope definition, scope verification, and scope change control." Based on your Integrated Project: Select two of the subdivisions above and discuss the primary issues that could arise from the process. Your response should begin with a definition of the selected subdivision before detailing the selected processarrow_forwardWhich of the following statements regarding PERT analysis is TRUE? Select one: O a Project variance is the sum of all activity variances. O b. Project standard deviation is the sum of all critical activity standard deviations. O c. Each activity has two estimates of its duration. O d. Only critical activities contribute to the project variancearrow_forward
- The MXN Sdn. Bhd. has identified eight activities that would need to be implemented in order to complete the construction project as listed in the table below. Using the PERT three-estimate approach, the company has obtained the estimated duration and the precedence relationships for each activity.

Delays in the project mean that the center mustrent other space at a nearby church at additional cost. Time and cost data for your project arecontained in below table. Your interest is in minimizing the cost of the project to the communitycenter.Using the normal times for each activity, what is the earliest date you can complete the project?Suppose the variable overhead costs are $50 per day for your project. Also, suppose that thecenter must pay $40 per day for a temporary room on day 15 or beyond.

Then please estimate the standard deviation of the overall project’s standard deviation σP . Part c) Suppose for the standard Normal random variable Z, we know P[−1 ≤ Z ≤ +1] ' 68%, P[−2 ≤ Z ≤ +2] ' 95%, and P[−3 ≤ Z ≤ +3] ' 99.7%.
