How Saco Defense Controlled the Situation ? At Saco Defense, lack of quality had created a crisis. When the government shut it down because it wasn't meeting quality standards, Saco brought back a TQM programme that had restored quality, increased production, and decreased costs. Based in Saco, Maine, the 178-year-old defense company was unable to adhere to the U.S. Navy's quality standards. Although Saco's weapons worked well, the government questioned the company's quality practices and policies. For example, if an employee discovered a defective bolt near the completion of an assembly process, the operator would replace the bolt but not document the problem. The presence of one defective bolt might mean that others from the same supplier or batch were also bad but were going undetected. Without follow-up, the underlying materials problem would not be identified and resolved. To solve these problems Saco Defense went through an organisational transformation. The key elements were : (1) empowering employees by giving them the responsibility and accountability for their performance, including the authority to halt production to correct problems: (2) forming work cells, that is, small businesses within the company that manage their production with limited supervision, and (3) reducing the workforce from 760 to about 450 employees and eliminating several layers of management. In addition, ongoing improvement projects at the company range from reducing cycle time and product cot to implementing programmes for skill integration. Productivity has increased, turnover is down, and the company pans to expand its international business. Source Stoner, A.F. James, R.Edward Freeman and Daniel R. Culbert, Jr., Management, Prentice-Hall of India Pvt. Ltd., 1998 (Ref: Joyce E. Santora, 'A Quality Program Transforms Saco Defense', Personal Journal, May 1993) Which step of controlling is reflected in para 2 of the above case ? Explain

Ecological Indicators The presence of dragonflies can reveal changes in the water ecosystems more quickly than studying other animals or plants. In fact, from the nymph to the adult stage, the dragonfly has a significant, positive ecological impact. Dragonfly eggs are laid and hatched in or near water, so their lives impact both water and land ecosystems. Once hatched, dragonfly nymphs can breathe underwater which enables them to eat mosquito larvae, other aquatic insects and worms, and even small aquatic vertebrates like tadpoles and small fish and in the air. Adult dragonflies capture and eat adult mosquitoes. Community wide mosquito control programs that spray insecticides to kill adult mosquitoes also kill dragonflies. Assertion: Releasing dragonflies in areas where there is an outbreak of malarial diseases can be an environment friendly method of control. Reason: Dragon flies are dominant species and will not allow mosquitoes to reproduce

(A) There are a number of item in the atomic energy programme which are being made indigenously. (B) Given the overall energy situation in India, the use of nuclear power in some measure is inescapable even while thermal and hydro power continue to be the dominant element.. (C ) However, commercial aspects of exploiting nuclear capabilities, especially for power-generation programmes, have been recently given high priority. (D) Atomic energy programmes have been subject to severe restrictions for very obvious reasons as the Department of Atomic Energy is becoming self-reliant in areas in which only a few countries have such capability. (E) Even to meet these nuclear power requirements, India critically requires a commercial-level power-generation capability, with its commensurate safety and nuclear waste management arrangements. (F) Thus, in Indian context energy security is also crucial, perhaps much more than it is for the U.S.A. because India imports a good part of its crude oil requirements, paying for it with precious foreign exchange.
