Karan Nath took over 'D'north Motor Company' from his ailing father three months ago. In the past the Company was not performing well. Karan was determined to improve the company's performance. He 
observed that the methods of production as well as selection of employees in the company were not scientific. 
He believed that there was only one best method to maximise efficiency. He also felt that once the method is developed, the workers of the company should be trained to learn that 'best method'. 
He asked the Production Manager to develop the best method and carry out the necessary training. The Production Manager developed this method using several parameters right from deciding the sequence of 
operations, place for men, machines and raw materials till the delivery of the product to the customers. This method was implemented throughout the organisation. It helped in increasing the output, improving the quality and reducing the cost and wastage. 
Identify and explain the principles and the technique of scientific management followed by the Production Manager in the above case.
