Out-sourcing, in-sourcing and off-sourcing

Out-sourcing = to get the source out of own company or group
In-sourcing = to get the source within own company or group still with own geographical territory
Off-sourcing does not mean not sourcing, but it should be read as off- shore sourcing = to get the source outside a geographical territory (out of the country)

outsourcing = get it (the task/job/thing) done by outsider of the company
insourcing = get it (the task/job/thing) done within the company
offshoring = get it (the task/job/thing) done by outsider of the company in another country

outsourcing 即係外判, 指某一部份工作由原先內部提供改為其他公司/個體去做。

insourcing最常用的解釋是從外判公司的角度看outsourcing，接他人的外判工作。

off sourcing(把工作外判到國外)。 More complex scenario on outsourcing as vendor located abroad.
