"What is it that we need to be a high performance organisation - being lean, it's about being agile and it's about having clearly addressed and delegated accountability," Guenter Butschek, MD and CEO of Tata Motors, told a news conference on Tuesday.

The company expects to see a much better fourth quarter, Chief Financial Officer C Ramakrishnan told the conference.
Car makers in India were also hit in the third quarter by Prime Minister Narendra Modi's "demonetisation" move in November, when he declared notes of Rs 500 and 1,000 illegal tender, taking about 86 percent of total currency out of circulation.

"Given this, JLR is in a more precarious position than its peers," IDFC Securities analyst Deepak Jain said in the report.
