• 1886 : A Vision Becomes Reality Charles E. Brown, still employed at Maschinen

fabrik Oerlikon, succeeded in transporting electricity over long distances. With his pioneering installations in Solothurn (1886) and Frankfurt (1891), he paved the way for the general electrification of modern society. In 1888 Brown began formulating plans to found his own electrical engineering company with his fellow employee Walter Boveri

• 1891 The Founding of the Company Brown and Boveri put their plans into practice on

2 October 1891 when they established the general partnership Brown, Boveri & Cie. in Baden. Baden was an ideal choice. Land was cheap and so was labour. The rail service was good and they were able to get their own railway siding. In their first contract, the young company fitted the Kappelerhof power station in Baden with all the requisite electrical equipment

• 1988 Unification The Swiss company BBC and the Swedish

company Asea decided to merge. On 1 January 1988 the two firms brought their previous group companies into the newly founded Asea Brown

Boveri Ltd as assets. What had been the BBC parent company now became ABB Switzerland.

• 1999 Concentration ABB went back to concentrating on its two core

fields of business: Power Technologies and Automation business units, including the former core unit Power Generation, were sold.

• 2004 Future ABB Switzerland continues its effective

implementation of the new strategy and has achieved impressive successes in both segments.

INPUT QUALITYThis section deals with the input.Section perform the primary function of checking the product coming from welders.

Actually welder are those who take granules as a raw material from company and make different pieces for switching accessories.

There are varieties of gauges available here:

threaded and plug gauge

standard wire gauge

gauge for measuring gap between two conductor

slip gauge

pin gauge

MCB coil inspection gauge

Surface meter and height gauge

SAMPLING PLAN

a plan which decides on what quantity of product how many pieces going to checkPlan helps input quality to estimate about what % the input is according to the measurement

Testing laboratory

Glow wire testing is performed by heating an element to a pre-determined temperature. The heated element is referred to as the glow wire. The sample to be tested is fixture in place and tissue paper is positioned directly below the sample. After reaching the pre-determined temperature, the element is then pressed into a sample material under a set force of 1N for 30 seconds. If ignition occurs, recordings are made to note the duration, flame height, and if drips of the material ignite the tissue paper.

The final destination

warehousing means holding or preserving goods in huge quantities from the time of their purchase or production till their actual use or sale.

Seasonal Demand- There are certain goods, which are demanded seasonally, likewoolen garments in winters or umbrellas in the rainy season. The production of thesegoods takes place throughout the year to meet the seasonal demand. So there is a needto store these goods in a warehouse to make them available at the time of need.

Large-scale Production - In case of manufactured goods, now-a-days productiontakes place to meet the existing as well as future demand of the products. Manufacturers also produce goods in huge quantity to enjoy the benefits of large-scale production, which is more economical. So the finished products, which are produced on a large scale, need to be stored properly till they are cleared by sales..

NEED OF WAREHOUSE

Gemba shop-floor meeting

Gemba meeting is a way in which member of the company and departmental heads discuss about the product quantity for a previous day

The Kaizen management originated in the best Japanese management practices and is dedicated to the improvement of productivity, efficiency, quality and, in general, of business excellence. The KAIZEN methods are internationally acknowledged as methods of continuous improvement, through small steps, of the economical results of companies.

PURPOSE•A clean well-organized, visualworkplace is fundamental to standardization.• Establishing a normal condition makesthe abnormal conspicuous.• Standardized work depends upon eachtool always being in the same place ... aplace for everything and everythingin its place.

(Set in Order or Straighten) Order - Arrange & identify for ease of use

(SHINE) Cleanliness on a daily basis

(SORT) Organize - Get rid of what is notneeded

(STANDARDIZE) Eliminate cause & standardize methods

(SUSTAIN) Discipline to plans &schedules
