There are three main concerns regarding interagency cooperation in intelligence operations. These are: security, cost and efficiency. There are legitimate concerns about the security of data when it is shared among agencies whose priorities may differ. There is also an increased risk of leaks with increases in the numbers of people who are able to have access to the data.
To obtain maximum levels of integration, drastically increased budget expenditures are required. There must be extensive investment in development so that there is general applicablity of systems between agencies. There also needs to be additional training of personnel in tasks and procedures that lie outside their primary roles.
The loss of the ability for agencies to act independently can significantly delay projects and actions that require immediate attention. Also, the timeliness of data sharing may be impacted by security or costs.
