Pursuant to a congressional request, GAO provided information on software reuse, focusing on: (1) issues that inhibit effective software reuse; and (2) Department of Defense (DOD) strategies to implement a departmentwide software reuse program.

GAO found that: (1) developing and maintaining software in organizations such as DOD is costly, and software reuse could both reduce such costs and increase software productivity and reliability; (2) technical issues involved in software reuse include domain analysis, software component classification, repository interoperability, software adaptation, and software metrics; (3) an organization must make a business decision to incorporate software reuse into the development process and gain management support and commitment; and (4) uncertainties in legal and acquisition policies involving intellectual property rights and liability hinder software reuse and need to be modified to better promote reuse.
