2. 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.

7. 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
8. MANAGING BOTTLENECK
5 Focusing Steps :
Identify the Bottleneck
Finding Largest WIP Inventory.
Exploit the Bottleneck
Optimize bottleneck machine speed.
Give maintenance high priority.
9. MANAGING BOTTLENECK
Subordinate Other Tasks
Letting the non-bottlenecks help the bottleneck
Everybody works at the pace of the bottleneck
Elevate the Bottleneck
Adding more people or machines
Training and mentoring more operators for the
bottleneck
Re-evaluate the process
New Bottleneck Emerges
Repeat the Steps and continue improving the system.

13. 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.

by various events.

The growth of value added products and the pressure to diversify is leading to bottlenecks in the supplychain.A bottleneck (or constraint) in a supply chain means the resource that requires the longest time in operations of the supply chain for certain demand. Usually, phenomena such as increase of inventory before a bottleneck and insufficiency of parts after a bottleneck are often seen. Statistically, since fluctuations are inconsistent, the phenomena (excess inventory and insufficient materials) do not always occur. In the case of hiking, a bottleneck means the slowest member in walking. An interval between the bottleneck member and the one before spreads, and narrows with the one after.1) Infrastructure Bottlenecks:•Infrastructure (nodes): ports / terminals (congestions, low capacity)•Infrastructure (links): transport services: rail/ road/barge: construction work, capacity problems, etc •Equipment2) Information Exchange Bottlenecks:•Technological incompatibility, limited investment in resources •Delay in data transmission, data quality, willingness to provide data (lack of trust/cooperation),3)Rules and Regulation•Customs Clearance Procedures & Security Inspections•Security Regulations (24h manifest)4) Bottlenecks due to Force Majeure•natural or human disasters (storms, hurricanes, accidents, terrorism,..)The deployment of ICT supports the management of bottlenecks in supply chain by:•Promoting supply chain integration-> Faster throughput time, higher liability of services (hinterland, port)•Increasing the flexibility to react to bottlenecks•Extending the visibility of supply chain (context of: globalisation) Facilitating Chain controlImplication: commitment to inter-company co-operation & informationsharing high degree of trust between chain operators However, if the bulk ordering selection experiences a break down which causes bottlenecking, then warehouse personnel must implement a process to continue the bulk ordering selection process. The warehouse personnel must first determine what caused the bottleneck process. Process time, is the time that work is being done by human being (not just buy a machine). If the machine become non functional, what processes are in place to continue the workflow? By implementing other processes to select bulk orders, will prevent the bottleneck process. Considering the Lead Time, which is the time it takes to complete the process from start to finish with little or no down time. These are the beginning of the main two process that is needed to allow the cross functional Teams to began their picking, pulling, and shipping process to the school in a timely manner. The flowchart includes all processes to connect and runs smoothly and to be completed without the bottleneck effect. If there is a bottleneck during the picking, pulling and shipping process then management must determine the next best process to eliminate downtime. By implementing a new procedure as a contingency plan, training will help ease bottlenecks and there would be no down time for shipping the food items to the schools. Strategic planning is to help provide an approach for determining the overall level of capital intensive resources for the facilities, equipment, and overall labor force size that best supports the company's long-range plans strategy to prevent bottlenecks.
A bottleneck, in a communications context, is a point in the enterprise where the flow of data is impaired or stopped entirely. Effectively, there isn't enough data handling capacity to handle the current volume of traffic.A bottleneck can occur in the user network or storage fabric or within servers where there is excessive contention for internal server resources, such as CPU processing power, memory, or I/O (input/output). As a result, data flow slows down to the speed of the slowest point in the data path. This slow down affects application performance, especially for databases and other heavy transactional applications, and can even cause some applications to crash. Similarly, bottleneck conditions can occur due to hardware failures. Bottlenecks can often be avoided by proactively monitoring traffic load trends over time and implementing improvements before serious problems develop.
Promising new business opportunities are many times identified in fields with technical bottlenecks. These bottlenecks limit product functions, and therefore hinder improved customer benefits to be realized. A bottleneck is the process within the value stream that limits the output. For instance, if there are 6 steps in the process of creating a customer order (taking the call may be step 1, Engineering review of the quote request may be step 2 and so on), whichever step requires the longest amount of time to complete is the bottleneck. As bottlenecks are identified and eliminated, products or information will flow through them more rapidly and new bottleneck processes will be identified and will need to be addressed.In order to reduce the bottlenecks we can use the following approach..Balance the workload: Other processes may have excess capacity that can be utilized to offload some work from the bottleneck process. This is typically a very good method to alleviate bottlenecks.
