CASE STUDY – 1
Compaq computer corporation has scrapped its long assembly lines and now makes its personal computers
with three person cells that assemble the computers produced to order. in this arrangement a three-person
team looks at the next customers order on a monitor to see the attributes of the computer to be assembled
(accessories, type of drives, etc.) and assembles computer specifically for that customer. in the three person
cells, one person prepares all the sub assemblies that go into a computer. the second person installs these
into computer frames. the third person performs all the tasks to make sure the circuits are connected properly.
in this method of production, parts and sub assemblies are inventoried before customer order are received,
but finished product are not, final assembly occurs only after receipt of orders. this allows compaq to match
production to customer orders and reduce cost of every step of production inventory, handling, freight, and
unsold goods. shifting to a produce-to-order system also decreases compaq’s dependence on market
forecast. compaq says that output of each employee in three person cell increased 23% and output per sq. ft
of the factory space increased 16% compared to produce-to-stock assembly lines.

Questions:
1. what are the advantages of cell type assembly lines?
2. how pull method of production is achieved in this case study?

CASE STUDY – 2
Northrop grumman is military aircraft manufacturer in the united states. air craft assembly is an expensive
operation because of the labour intensity and sporadic quality problems involved in drilling millions of holes
each year. more than 70000 holes are manually drilled and fastened per ship set in each of the northrop
grummnan’s military air frames, accounting for nearly 44% of the total assembly cost.

The current method of hole drilling and counter sinking for fastener installation uses unique drill fixtures for
each assembly and sub assembly processed, at an average cost of $50,000/- each. well over 900 conventional
drill fixtures are required for air frame assembly on each programme. each drill fixture is constructed through a
laborious process. variations exists in the quality of drilled holes because each drill operator controls the drilling
speed and feed as a hole is made with the air powered, handheld drill.

Northrop grumman is very interested in finding new production technologies to modernize its manufacturing
operations particularly its hole drilling process. objective of its modernization effort is to identify automation
opportunities for its assembly lines that will increase flexibility while simultaneously reducing direct labour cost
and improving quality. in addition to increase the quality and efficiency of assembly processes areas must be
identified where automation will eliminate the need for many of the assembly fixtures and drill templates
currently in use, thereby reducing recurring and non recurring tooling costs.

Questions:
1) why there are variations in the quality of the holes drilled?
2) why modernization is sought by northrop grumman?
3) why hole drilling process is an important process for northrop grumman?
