Group Technology brings together and organizes

Explanation:

Group Technology:

• Group technology (GT ) is a concept to increase production efficiency by grouping various parts and products with similar designs and production processes.
• Similarities among parts permit them to be classified into part families.
• In each part family, processing steps should be of a similar type.
• The improvement is typically achieved by organizing the production facilities into Manufacturing cells, that specialize in 
  production of certain part families.
• Grouping the production equipment into machine cells where each cell specializes in the production of a part family is called cellular manufacturing.

Hence cellular layout is followed to achieve advantages of group technology.
