Work requires no previous experience in a craft or trade.
Each task is performed according to detailed instructions, written or oral. Assignments are usually for a short duration and when completed are usually checked for accuracy, adherence to instructions and established regulations, as well as the worker's rate of performance. Where the work is usually repetitive and the employee works from detailed instructions, the difficulty is usually limited to accuracy and speed. Tasks are clearly defined, highly organized, closely related and often repetitive. Few if any alternatives exist for methods or procedures to be used.
