Another essential aspect presented in the Goal is the concept of bottlenecks which 
illustrates the idea of productivity. In the book, constraints get depicted as barriers that limit the 
production process. For instance, the author presents a practical example in a hiking group where 
a chubby boy slows down the whole expedition (Goldratt and Cox 33). It describes the 
complexity of constraints as broken chains that affect the business as a whole rather than a single 
section. In this case, the chain is as strong as its weakest link. Therefore, the improvement of the 
constraints increases the performance of the business. The book provides five focusing steps 
including the identification of restriction, exploitation of the specifics related to the bottleneck 
and aligning and management of the systems around the constraint. The two other measures 
include elevating the performance of the limitation and repetition of the process to ensure 
efficiency. Indeed, many businesses in the current globalized market face different types of 
obstacles whether in the supply, marketing or the production process. The steps provided in 
mitigating and managing constraints are essential in improving business performance and profits. 
The improvements involve subordinating other production processes to bottlenecks and elevating 
bottleneck’s throughput through outsourcing some of the constraint’s work to external suppliers. 
In the event a constraint is identified again, repetition is essential to find the new bottleneck. 
The Goal provides knowledge on that uncovers the principles of the theory of constraints 
that can be easily applied not only in manufacturing but also other industries. It gives insight on 
measurements used that differ from traditional efficiency methods. Obstacles are the key to 
unlocking the performance of a firm. The theory of constraints provides practical solutions in 
managing business barriers through their identification and application of best solutions. 
Effective management of constraints and measurement tactics results to improved performance 
through rapid response culture, reduced cycle time, free cash flows, and higher net profit among
