Mango Electronics Inc. is a Fortune 500 company that develops and markets innovative consumer products. The development process is as follows.

Mango researches new technologies to address unmet market needs.

Patents are filed for products that have the requisite market potential.

Patents are granted for a period of 20 years starting from the date of issue.

After receiving a patent, the patented technologies are then developed into marketable products at five independent development centers.

Each product is only developed at one center. Each center has all the required skills to bring any of the products to market (a center works on one product at a time).

On average, Mango files a patent every 7 months (with a standard deviation of 7 months). The average development process lasts 28 months (with a standard deviation of 56 months).
