3. History of Concurrent Engineering
A set of lines are
concurrent if
they intersect at
same point.
All non-parallel
lines are
concurrent
 CE is a work methodology emphasizing the parallelisation of tasks,
which is called Simultaneous Engineering or Integrated Product
Development (IPD)
 Relatively recent term - Beginning in the early 1990s started with
aerospace industry later for automobile, process industry and others
 One of the first motivations for a concurrent engineering approach to
the product development is a desire to shorten the total time that
takes to bring a product to the market

7. Concurrent Engineering
1. Increasing product variety and technical complexity that prolong the product
development process and make it more difficult to predict the impact of design
decisions on the functionality and performance of the final product
2. Increasing global competitive pressure from the emerging concept of reengineering
3. The need for rapid response to fast-changing consumer demand
4. The need for shorter product life cycle
5. Large organizations with several departments working on developing numerous
products at the same time
6. New and innovative technologies emerging at a very high rate, thus causing the new
product to be technological obsolete within a short period

9. CE- Rule based Method Applications
 CE is the application of mixture of all techniques to evaluate the total life-cycle cost
and quality
 Design for
1. Manufacturing
2. Quality
3. Cost
4. Assembly
5. Safety
6. Reliability
7. Failure-Mode and Effects Analysis
8. Product prototyping

10. CE-Case Example Study
1030-03-2019
 Well Known company in automotive Propeller Shaft Manufacturing industry having
use of sequential engineering approach
 Wants to use CE for 3 parameters:
1. Unit Cost
2. Mfg. Lead Time
3. Quality
 Previous:
Mfg dept accepts specifications and attempts to find the best manufacturing technology
to accommodate request made by design. Mfg dept will challenge specification only if
design is not producible
 Now:
All depts. work together decides tolerances, machines technology used improving all 3
parameters

11. CE-Case Example Study
1130-03-2019
Sequential Concurrent
• Tolerance of ±0.03”
accepted from D&D
• So turret lathe is used for
mfg
• So unit o/p cost= 23.97
• Mfg. lead time=1485 units
• No. of rejects= 465
• Tolerance of ±0.03” OK
• Engine lathe is used for mfg
for better capability
• Process cost increases
• So unit o/p cost= 21.63
• No of rejects= 155
Stage 1
• Tolerance change to ±0.04”
• Engine lathe is used for mfg
• So unit o/p cost= 19.78
• No of rejects= 46
Stage 2
• Tolerance as it is ±0.04”
• Auto Screw M/C is used for
mfg
• So unit o/p cost= 22.04
• No of rejects= 01
• Mfg. lead time=750 units
Stage 3
All data for 1000 parts with
Unit raw mtl= Rs.10
Unit processing= Rs.7
Final
• Unit cost= 8.95%
• Quality= zero scrap than 465
• Lead time= 98%

12. Advantages of Concurrent Engg
1. Reduces project cycle time
2. Life cycle cost of project reduces
3. All project phases are executed
simultaneously helping in managing
changes that required for effective
project achievement
4. Focuses on customer requirement at
every phase of projects so quality
project outcome
5. Provides 7Cs improving project team
effectiveness

13. Disadvantages of Concurrent Engg
1. Complex to manage- considerable reconstruction of organization and the extensive
retraining of workers
2. Relies on everyone working together hence communication is critical
3. Room for mistakes are small as it impacts all the departments or discipline ( electrical,
mechanical or software)
4. Rushing products to the market can sometimes be a mistake
1330-03-2019

14. Conclusions
1. Concurrent Engineering process is demonstrated with case study
2. In today’s fast hanging world where as complex as automobile product launching
time has came to almost 6 months, CE plays very imp role
3. Cost of including CE in all process is les than its benefits so highly recommended
4. CE having great advantages but need to have focused management to get full
results
