Key responsibility roles:
(1) Responsible.
Those who do the work to achieve the task. There is at least one role with a participation type of responsible, although others can be delegated to assist in the work required.
(2) Accountable (also approver or final approving authority).
The one ultimately answerable for the correct and thorough completion of the deliverable or task, and the one who delegates the work to those responsible. In other words, an accountable must sign off (approve) on work that responsible provides. There must be only one accountable specified for each task or deliverable.
(3) Consulted (sometimes counsel).
Those whose opinions are sought, typically subject matter experts; and with whom there is two-way communication.
(4) Informed.
Those who are kept up-to-date on progress, often only on completion of the task or deliverable; and with whom there is just one-way communication. [Responsibility assignment matrix. Wikipedia]

Diversification is a corporate strategy to increase sales volume from new products and new markets. Diversification can be expanding into a new segment of an industry that the business is already in, or investing in a promising business outside of the scope of the existing business.
Diversification is part of the four main growth strategies defined by Igor Ansoff's Product/ Market matrix.
Ansoff pointed out that a diversification strategy stands apart from the other three strategies. The first three strategies are usually pursued with the same technical, financial, and merchandising resources used for the original product line, whereas diversification usually requires a company to acquire new skills, new techniques and new facilities.
