Critical Path Method
The critical path is the longest succession of tasks that has to be successfully completed to conclude a project entirely. The tasks involved in the sequence are called critical activities, as any task getting delayed will result in the whole project getting delayed. To determine the time duration of a project, the critical path has to be identified. The critical path method or CPM is used by project managers to evaluate the least amount of time required to finish each task with the least amount of delay.
Cost Analysis
The entire idea of cost of production or definition of production cost is applied corresponding or we can say that it is related to investment or money cost. Money cost or investment refers to any money expenditure which the firm or supplier or producer undertakes in purchasing or hiring factor of production or factor services.

Project Management is all about management and optimum utilization of the resources in the best possible manner to develop the software as per the requirement of the client. Here the Project refers to the development of software to meet the end objective of the client by providing the required product or service within a specified Period of time and ensuring high quality. This can be done by managing all the available resources. In short, it can be defined as an application of knowledge, skills, tools, and techniques to meet the objective of the Project. It is the duty of a Project Manager to achieve the objective of the Project as per the specifications given by the client.

![L. Winston Martin (an allergist) has an excellent system for handling his regular patients who come in just for allergy injections. Patients
arrive for an injection and fill out a name slip, which is then placed in an open slot that passes into another room staffed by one or two
nurses. The specific injections for a patient are prepared, and the patient is called through a speaker system into the room to receive
the injection. At certain times during the day, patient load drops and only one nurse is needed to administer the injections. Use Exhibit
712.
Let's focus on the simpler case of the two-namely, when there is one nurse. Also, assume that patients arrive in a Poisson fashion
and the service rate of the nurse is exponentially distributed. During this slower period, patients arrive with an interarrival time of
approximately 3 minutes. It takes the nurse an average of 2.50 minutes to prepare the patients' serum and administer the injection.
a. What is the average number of patients you would expect to see in Dr. Martin's facilities? (Do not round intermediate calculations.
Round your answer to 2 decimal places.)

b. How long would it take for a patient to arrive, get an injection, and leave? (Round your answer to 2 decimal places.)

c. What is the probability that there will be three or more patients on the premises? (Do not round intermediate calculations. Round
your answer to 1 decimal place.)

d. What is the utilization of the nurse? (Do not round intermediate calculations. Round your answer to 1 decimal place.)

e. Assume three nurses are available. Each takes an average of 3.00 minutes to prepare the patients' serum and administer the
injection. What is the average total time of a patient in the system? (Do not round intermediate calculations. Round your answer to 2
decimal places. Do not interpolate your /u ratio when using Exhibit 7.12. Use the closest Nµ ratio appearing in the table.)
