BOTTLENECKS

WHAT IS A BOTTLENECK?

Performance an entire system is limited by a single or limited number of components.

The term is taken from its literal meaning.

Fundamental intuition about bottlenecks carried over from the days of Henry Ford.

MANUFACTURING BOTTLENECKS

It is a stage in a process that causes the entire process to slow down.

Restricts the output of production facilities.

CAUSES OF MANUFACTURING BOTTLENECKS

PHYSICAL

• Equipment breakdown• Inherent equipment

capacity limitations

HUMAN

• Poor training and skill levels

• Technical support problems

LATENT • Inappropriate scheduling

MANAGING BOTTLENECK

In 1984 Dr. Eliyahu M. Goldratt introduced the Theory of Constraints in his book the Goal. The Five Focusing Steps :

Identify the process' constraints

Decide how best to exploit the process constraints

Subordinate everything else to the above decisions

Evaluate the process constraint

Remove the constraint and re-evaluate the process

MANAGING BOTTLENECK

Identify the Bottleneck Finding Largest WIP Inventory.

Exploit the Bottleneck Optimize bottleneck machine speed. Give maintenance high priority.

5 Focusing Steps :

Subordinate Other TasksLetting the non-bottlenecks help the bottleneckEverybody works at the pace of the bottleneck

Elevate the BottleneckAdding more people or machinesTraining and mentoring more operators for the

bottleneck

Re-evaluate the processNew Bottleneck EmergesRepeat the Steps and continue improving the

system.

there is excessive contention for internal server resources

BOTTLENECKS IN CORPORATE SECTOR

Bottleneck in the process

Bottleneck in HR

Communication gap as a bottleneck

POPULATION BOTTLENECKS

It is an event that drastically reduces the size of a population.

It produces a decrease in the gene pool of the population.

Production bottleneck may be caused by various events. Surviving
