Investment
In general, to invest is to allocate money (or sometimes another resource, such as time) in the expectation of some benefit in the future – for example, investment in durable goods, in real estate by the service industry, in factories for manufacturing, in product development, and in research and development. However, this article focuses specifically on investment in financial assets.
Investment Management
Investment management is the professional asset management of various securities (shares, bonds and other securities) and other assets (e.g., real estate) in order to meet specified investment goals for the benefit of the investors. Investors may be institutions (insurance companies, pension funds, corporations, charities, educational establishments etc.) or private investors (both directly via investment contracts and more commonly via collective investment schemes e.g. mutual funds or exchange-traded funds).
Management
Management (or managing) is the administration of an organization, whether it is a business, a not-for-profit organization, or government body.

The term "management" may also refer to those people who manage an organization.

Management
Management is defined here as the accomplishment of desired objectives by establishing an environment favorable to performance by people operating in organized groups. Each of the managerial functions (planning, organizing, staffing, , directing, and controlling) is analyzed and described in a systematic way. As this is done, both the distilled experience of practicing managers and the findings of scholars are presented. This is approached in such a way that the reader may grasp the relationships between each of the functions, obtain a clear view of the major principles underlying them.

Administration is the most obvious part of government; it is government in action; it is the executive, the operative, the most visible side of government, and is of course as old as government itself.
