The company can assemble computer system and develop the main programme only when it has designed input/output system appropriately. On the other hand, developing input/output routine requires that the company has already designed monitoring system. Once the main programme is developed, the company can create data base. But, to install the system, both assemble computer system and development of input/output routine must remain completed. Finally, the testing and implementation stage require that the company has already created database and installed the system. Requirement: Using PERT method, determine the critical path and compute the expected completion time. ii. Determine the average daily cost for each activity and the probability that the project will be completed within maximum 53 days. iii. After 30 days, you have calculated the percentage of tasks completed (see percentage of task completed column). Determine whether the project is going as planned or not. Suggest your policy
