A common way of categorising knowledge in the Computing and IT world is: Strategic, Tactical, Operational.
In a company or organisation this is the type of knowledge used by senior management and directors. In a supermarket chain decisions are made at this level over where to open new stores, how to liaise with government bodies, fit in with planning regulations, where to locate factories or stores and whether enter new markets. In a computer game this equates to making decisions over the outcome, direction and overall aim or mission of a game.
In a company or other organisation this type of knowledge is concerned with how strategic aims can be met by manipulating the resources available, for example plant location, size, layout, logistics, supply chain, and so on. Store managers and regional managers will use tactical knowledge to optimise sales and market share by, for example, analysing local markets, choosing products to sell, placing goods in the best location in stores and so on. In a computer game tactical knowledge deals with the way a player will interact with the environment and in the case of MissionMaker how the game designer will define the way a game is played. One tactic of a game, for example, may involve accumulating points by picking up objects in order to balance loss of points through other factors.
Operational knowledge is used by employees to make sure that actions vital to the functioning of a plant are carried out , for example stacking shelves in a store or maintaining a supply of components in a factory. In a computer game operational knowledge is what the designer or player needs to create and solve a particular puzzle such as opening a door or getting past an aggressive character.
