Morning Sky, Inc. (MSI), manufactures and sells computer games. The company has several product lines based on the age range of the target market. MSI sells both individual games as well as packaged sets. All games are in CD format, and some utilize accessories such as steering wheels, electronic tablets, and hand controls. To date, MSI has developed and manufactured all the CDs itself as well as the accessories and packaging for all of its products.

The gaming market has traditionally been targeted at teenagers and young adults; however, the increasing affordability of computers and the incorporation of computer activities into junior high and elementary school curriculums has led to a significant increase in sales to younger children. MSI has always included games for younger children but now wants to expand its business to capitalize on changes in the industry. The company currently has excess capacity and is investigating several possible ways to improve profitability.

MSIs educational products are currently sold without any supplemental materials. The company is considering the inclusion of instructional materials such as an overhead slide presentation, potential test questions, and classroom bulletin board materials for teachers.
