Available capacity if an organization has the equipment, necessary skills and time, it often makes sense to produce an item or perform a service in house. The additional costs would be relatively small compared with those required to buy items or subcontract them.
2.
Expertise. If a firm lacks the expertise to do a job satisfactorily, buying might be a reasonable alternative.
3.
Quality considerations. Firms that specialize can usually offer higher quality than an organization can attain itself. Conversely, special quality requirements or the ability to closely monitor quality may cause an organization to perform a job itself.
4.
Nature of demand. When demand for an item is high and steady, the organization is often better off doing t he work itself. However, wide fluctuations in demand or small orders are usually better handled by specialists, who are able to combine orders from multiple sources, which results in higher volume and tend to offset individual buyer fluctuation.
5.
Cost. Any cost savings achieved from buying or making must be weighed against the preceding factors. Cost savings might come from the item itself or from transportation cost savings.

One employee’s study yielded a mean of 6.4 minutes and standard deviation of 2.1 minutes with 95% confidence Interval. Other employee’s study yielded a mean of 2.1 minutes and standard deviation of 6.4 minutes with confidence interval of 95%. Now how many observations you will need if desired maximum error is 10% of sample mean?(z= 1.96) Do both the employees have same number of observations?
ANS: Employee # 1 : Mean time = X = 6.4mints Standard Deviation = S = 2.1mint. z = 1.96

MIDTERM EXAMINATION
error = A = 10% = 0.1 n = (zs/ax) 2 = [(1.96) (2.1)/(0.1)(6.4)] 2 = [4.116/0.64] 2 = (6.43125)2 = 41.36 41 observations
Employee # 2 : Mean time = X = 2.1mints Standard Deviation = S = 6.4mint. z = 1.96
error = A = 10% = 0.1 n = (zs/ax) 2 = [(1.96) (6.4)/(0.1)(2.1)] 2 = [12.544/0.21]2 = (59.733)2 = 3568.03 3568 observations
