A company making tires for bikes is concerned about the exact width of its cyclocross tires. The company has a lower specification limit of 22.8 mm and an upper specification limit of 23.3 mm. The standard deviation is 0.14 mm and the mean is 23.1 mm. What is the process capability index for the process?

the process capability index for the process is 0.4761

Explanation:

The computation of the process capability index for the process is shown below:

= minimum of [(23.3-23.1) ÷ (3 × 0.14),(23.1 - 22.8) ÷ (3 × 0.14)]

= minimum of (0.4761, 0.7142)

= 0.4761

Hence, the process capability index for the process is 0.4761

The same should be considered and relevant  

in 2001, dell computer became the world’s largest personal computer vendor, continuing to

gain market share and post profits in an industry struggling with slumping sales and billions of

dollars in losses. dell sells 90% of its pcs directly to the final customer, largely bypassing the

reseller channel that accounts for most of the world’s pc sales. this direct customer relationship

is the key to dell’s business model, and provides distinct advantages over the indirect sales

model. dell’s direct relationship with the customer allows it to tailor its offerings to customer

needs, offer add-on products and services, and use the internet to offer a variety of customer

services. in addition, dell’s pcs are built to customers’ specifications upon receipt of an order,

giving dell additional advantages over indirect pc vendors who must try to forecast demand and

ship products based on those forecasts. dell’s direct sales and build-to-order model has achieved

superior performance in the pc industry in terms of inventory turnover, reduced overhead, cash

conversion, and return on investment (kraemer, et al., 2000).
