The term health insurance is generally used to describe a form of insurance that pays for medical expenses. It is sometimes used more broadly to include insurance covering disability or long-term nursing or custodial care needs. It may be provided through a government-sponsored social insurance program, purchased on a group basis (e.g., by a firm to cover its employees) or purchased by individual consumers. In each case, the covered groups or individuals pay premiums or taxes to help protect themselves from high or unexpected healthcare expenses. Similar benefits paying for medical expenses may also be provided through social welfare programs funded by the government rather than the beneficiaries.

Health insurance works by estimating the overall risk of healthcare expenses and developing a routine finance structure (such as a monthly premium or annual tax) that will ensure that money is available to pay for the healthcare benefits specified in the insurance agreement. The benefit is administered by a central organization, most often either a government agency or a private or not-for-profit entity operating a health plan.

¹ Market-based health care systems such as that in the United States rely heavily on private and not-for-profit health insurance. In the U.S., according to the Census Bureau, some 60% of the population receives health insurance coverage through employer-sponsored plans. Government programs cover another 27% of the population, and about 9% of the population purchases insurance directly (there is some overlap in these figures).

A pension is a steady income given to a person (usually after retirement). Pensions are typically payments made in the form of a guaranteed annuity to a retired or disabled employee. Some retirement plan (or superannuation) designs accumulate a cash balance (through a variety of mechanisms) that a retiree can draw upon at retirement, rather than promising annuity payments. These are often also called pensions. In either case, a pension created by an employer for the benefit of an employee is commonly referred to as an occupational or employer pension. Labor unions, the government, or other organizations may also fund pensions.

Occupational pensions are a form of deferred compensation, usually advantageous to employee and employer for tax reasons. Many pensions also contain an insurance aspect, since they often will pay benefits to survivors or disabled beneficiaries, while annuity income insures against the risk of longevity.

While other vehicles (certain lottery payouts, for example, or an annuity) may provide a similar stream of payments, the common use of the term pension is to describe the payments a person receives upon retirement, usually under pre-determined legal and/or contractual terms.

Risk management is the human activity which integrates recognition of risk, risk assessment, developing strategies to manage it, and mitigation of risk using managerial resources. The strategies include transferring the risk to another party, avoiding the risk, reducing the negative effect of the risk, and accepting some or all of the consequences of a particular risk.

Some traditional risk managements are focused on risks stemming from physical or legal causes (e.g. natural disasters or fires, accidents, death and lawsuits). Financial risk management, on the other hand, focuses on risks that can be managed using traded financial instruments.

Objective of risk management is to reduce different risks related to a preselected domain to the level accepted by society. It may refer to numerous types of threats caused by environment, technology, humans, organizations and politics. On the other hand it involves all means available for humans, or in particular, for a risk management entity (person, staff, organization).

Management consulting refers to both the industry, and the practice of, helping organizations improve their performance, primarily through the thorough analysis of existing business problems and development of plans for improvement. Organizations hire the services of management consultants for a number of reasons, including, for example, to gain external, and presumably more objective advice and recommendations, to gain access the consultants' specialized expertise, or simply as temporary help during a one-time project, where the hiring of permanent employees is not required. Because of their exposure to and relationships with numerous organizations, consultancies are also said to be aware of industry 'best practices,' although the transferability of such practices from one organization to another is the subject of debate. Consultancies may also provide organizational change management assistance, development of coaching skills, technology implementation, strategy development, or operational improvement services. Management consultants generally bring their own, proprietary methodologies or frameworks to guide the identification of problems, and to serve as the basis for recommendations for more effective or efficient ways of performing business tasks.

Management consulting refers generally to the provision of business consulting services, but there are numerous specializations, such as Information technology consulting,human resource consulting, and others, many of which overlap, and most of which are offered by the large diversified consultancies listed below. So-called 'boutique' consultancies, however, are smaller organizations specializing in one or a few of such specializations.

Management Consulting is becoming more prevalent in non-business related fields as well. As the need for professional and specialized advice grows, other industries such as government, quasi-government and not-for-profit agencies are turning to the same managerial principles that have helped the private sector for years.

One important and recent change in the industry has been the spin-off or separation of the consulting and the accounting units of the large diversified firms. For these firms, which began business as accounting firms, management consulting was a new extension to their business. But precipitated by a number of highly publicized scandals over accounting practices, such as the Enron scandal, accountancies began divestiture of their management consulting units, to more easily comply with tighter regulatory scrutiny that arose in the wake of the scandals.
