# Thread: turn around time calculation

1. ## turn around time calculation

hi,
i want to calculate the TAT between two times. the TAT target is <= 2 hours. i used the following formula
a1 has 3/13/2009 (received date)
b1 has 7:08 AM (received time)
c1 has 3/13/2009 (completed date)
d1 has 9:08 AM (completed time)
e1 has TAT formula :- '=IF((D1-B1)*1440<=120,"Met TAT","Not Met TAT")

however this formula does not work in the following conditions.

In these conditions, it is considered that TAT is met.
1. When the difference in time is <=2 hours .... for TAT calculation, on working days and working hours are taken into consideration.

To illustrate.
Day begins : 8:00 AM
Day ends : 4:00 PM

If job is received at 3:30 PM and completed the next working day by 9:30 AM, then it is considered TAT is met.
calculation = 4:00 PM - 3:30 PM = half hour + next day's 9:30 AM - 8:00 AM = 1.5 hours, therefore, total working hours used to complete the job is within the agreed TAT.

If job is received and completed on non working days and during non working hours, it is considered TAT met.

If job is received almost at the end of the day, say, 3.30 PM and job is completed at 8:00 PM same day, then it is considered TAT met, rationale, only half an hour of working hours used to complete the job.

Any suggestion to build upon my formula is greatly appreciated.

=(NETWORKDAYS(A2,B2,\$J\$4:\$J\$10)-1)*(J\$3-J\$2)+IF(NETWORKDAYS(B2,B2,\$J\$4:\$J\$10),MEDIAN(MOD(B2,1),J\$3,J\$2),J\$3)-MEDIAN(NETWORKDAYS(A2,A2,\$J\$4:\$J\$10)*MOD(A2,1),J\$3,J\$2)

Sir, your post was very much helpful for me. but my only doubt is for the desired turn around time <= 2 hrs you have substituted (D1-B1)*1400<=120 in the formula. I didn't understand the logic behind that so that I can apply the same for desired turnaround time of <= 4 hrs.
Looking forward for your reply and help. I am an MBA student of VIT University doing my internship project at TAFE, My email Id is ratish.ratheesh.t@gmail.com.
Thank You Sir!!
