e for preparationfor manufacture. By telescoping theseactivities the time between start of de-velopment and start of manufacture isreduced substantially. To accomplishthis there are a number of branch labora-tories at various Western Electric plants.Such close cooperation feeds back in-formation to BTL on the state of the art 12 of manufacturing technology, and im-measurably speeds the process of approv-ing new devices and product changesinitiated by the manufacturer to cut costsand clear up production problems. ■ As the Bell System grew and itsgrowth was paralleled by bigger prob-lems for Bell Laboratories, it becameevident that more than just research anddevelopment would be required to copewith the growing complexities success-fully. A new discipline called systems en-gineering evolved. In 1955, systems engineering became avice presidential group at Bell Labora-tories. Since then it has grown rapidly,and today there are over 750 professionalstaff people in the systems engineering

Systems engineeringis organized roughly parallel to the de-velopment organization, but on a smallerscale. It forms the major interface be-tween Bell Laboratories and A.T.&T.,and its charter is a big order: to knowthe problems and economics of the Op-erating Companies and to relate thisknowledge to the scientific and technicaladvances that afifect communications. Systems engineering makes many ofthe recommendations for developmentprojects and maintains close liaison withthe research people. Systems engineer-ing also takes on some projects that falloutside of traditional technical disci-plines, such as the great problem of net-work management. Using such tech-niques as operations research—mostlymathematical simulation—systems engi-neers can often work out ways to makethe system operate more efficiently wi
