Question 2

Different scenarios are to be considered while calculating the lead-time of patients for the surgery process. Four processes are identified in order to know the minimum time to cover the surgery steps from first appointment until the discharge.

	Activities	Duration	Preceding	Est	Eft	Lst	Lft	Slack
A	First Appointment	5	-	0	5	0	5	0
B	Initial Consultation	30	A	5	35	5	35	0
C	Preliminary Test Request	10	B	35	45	35	45	0
D	Test 1 Appointment	5	C	45	50	45	50	0
E	Test 1	60	C	45	105	45	105	0

	Mean	22
	Standard Deviation	23.61144

	Lead Time	180
	New adjusted time	150
	P	1.270571
	Z-Score	89.80%

Cash: Open Surgery (Excluding the seminar)

If the average patients would perform the process of paying the cash instead of reimbursement from insurance, then the lead-time would decrease due to the additional time spend under the case of insurance approval of the document of surgery.

It has been analysed that only five slacks would perform the zero value due to the need of the process and pre-requisite of surgery. The average lead-time to spend under the case was 180 days of the patient, but the expected time is assumed 150, due to the time reduction of seminar from the process. In conclusion, the project can be accomplished with at 89.80% chance.

	Activities	Duration	Preceding	Est	Eft	Lst	Lft	Slack
A	First Appointment	5	-	0	5	0	5	0
B	Initial Consultation	30	A	5	35	5	35	0

	Standard Deviation	27.0

	Lead Time	210
	New adjusted time	180
	P	1.11
	Z-Score	86.65%

Cash: Laparoscopic (Excluding the seminar)

On the other side, if certain activities would perform under the case of Laparoscopic, then the average time would increase due to the estimated lead-time of patient with 210 days to cover. Therefore, with high standard deviation of the slack duration, the company would have a chance to complete a net result of 86.65% under the particular scenario...............
