Series of TQM (total quality management) initiatives over the past few years have helped Tata Steel reduce production cost so much that the cost of production of a tonne of saleable steel has dropped by an estimated 2.5 per cent, according to company sources. The initiatives, as the sources point out, were launched right at the raw material stage. Thus, the improvement of the working of the coal washeries has brought down ash content in domestic coal, sourced from the company's own West Bokaro and Jharia collieries, from 17 per cent to 13 per cent (West Bokaro) and from around 18 per cent to 15 (Jharia).
