Sample Research Project on Faulty Products from Coca-Cola Company

Part 1: Business problem and research objectives


It is the main aim or primary objective for any company to meet consumer expectations in the products or services they offer. By achieving this, the company is able to enjoy a wide market share and more so attract new customers. Most of the production companies achieve this by heavily investing on research to come up recommendations and outlines on how they can improve or change their products to boost their chances in the market. Taking into account consumers’ views and integrating them to their production line to improve the products has also benefited production companies (Turnberg 2001). Moreover, production companies tend to invest more in technology driven mechanisms to among other things have an edge over their competitors in the market. Expansion of their operations, for example establishing their companies in different countries is a major factor considered by these companies. Despite all these measures, there are some major setbacks that constantly affect the operations of companies and extensively their customers’ views. A major factor is production of faulty products brought by human and or machine errors. The companies are made aware of the existence of such products by their customers who are mostly dissatisfied by this mess. The alarming rate in which companies are producing faulty products influenced the need to study faulty products produced by Coca-Cola Company.Failure to study this problem could have a negative impact on the company’s market share and consumers may opt for subsidies.

Historical background

Production ethics and codes are clear according to consumer watch bodies.Coca-Cola being arguably the largest beverage producer in the world is not exceptional to abide to the set rules and guidelines. Unknown to many, Coca-Cola has its branches to slightly more than two hundred countries and has more than four hundred products, mainly beverages, foods and snacks. From its establishment in 1886 by John Pemberton, the company has witnessed a robust growth in production and distribution as well as invention of new products over the years. The company is credited for infusing modern technology in its operations including the interaction with customers. Coca-Cola Company strengthened ties with sporting sector in the 90’s when in 1993 the Coca-Cola advertising initiative was launched. This greatly boosted the sale of Coca-Cola’s products and established the relationship between the company and the sporting sector. Another notable change is the launch of live positively initiative in 2009 where the company embarks on drastically reducing pollution by reducing emission of carbon and more so embarking on recycling mechanisms of used products. These among other initiatives and market strategies have kept the company on top in the market

However, despite the company being a reputable organisation, there have been several complains about the products from the consumers. Consumers have occasionally raised an alarm over faulty products notably ‘flat’ soft drinks and content of some particles mostly in the soft drinks. Consequently, the good relationship between Coca-Cola and consumers has led to the need for a comprehensive research to address this concern. The impact of this concern to the operations of the company has been evaluation of their production line which involves machines, human and ingredients used. The company is determined to keep their customers satisfied hence need to put into consideration their concern is eminent.

Problem statement

This study thoroughly investigates the causes or events leading to production of faulty products from Coca-Cola Company. Due to the processes of production involved, machines and human contributions will be the main subjects in the study. However, considering the chain involved before consumers get the products, other factors like distribution and storage will be put into consideration. The outcome of the study will definitely help the stakeholders precisely the management to come up with appropriate measures that will curb the faulty products reaching the customers.

Research question

To make this research a success, several questions must be addressed to help come up with the real problem that is causing faulty products to reach the market. The question of the efficiency of the machines used in production must be addressed in details. This will enable identifying if indeed the machines are faulty consequently influencing production of faulty products. In addition to this, the question of whether the faulty products are as a result of human error is equally important. It should be investigated whether human error precisely in coming up with ingredients is to blame for this mess. Human error can also arise in improper fixing of machines used in production. This can be tricky since one can mistake human error to machine error. Lastly, the question of whether the distribution and storage facilities are the cause of having faulty products must also be addressed. The findings of these questions will help in coming up with appropriate measures towards this concern.

Research objective

The research objective of this study is to identify the causes of faulty products from Coca-Cola Company. Moreover, the research tends to establish the proportion of faulty products reaching the consumers.


Faulty products are definitely caused by errors in the materials, machines or human power and processes used to produce them. Malfunctioning of one party trickles down to the end result which is the product hence a faulty or undesired outcome is experienced (Connell 1991). In cases of human error, poor design, improper fixing and wrong operation of the used machine leads to faulty products at the end. Improper fixing may be as a result of unqualified professionals being involved in this process. Notably, in accident related cases human error is blamed for about 70% of the reported cases (Turnberg 2001). The common human error are classified into three main categories. Mistakes is the most common and occurs when individuals make a choice without proper consent of the challenge or the problem.(Sirohi 2013) Knowledge based mistake is the other kind of error and is mostly got when individuals provide a wrong solutions as a result of wrong assessment of the problem. This kind of error is influenced by factors like biasness and insufficient information. Rule-based mistake is the last kind of error which is basically applying a wrong rule for a certain solution (Bluff 2015). Unlike the early days when employees had little or no responsibilities for accidents or mistakes, currently employees are almost entirely held responsible for the mistakes in their fields. The mistakes trickling down to final products and other factors have influenced reduction in consumption of the affected product. Precisely in the United States 60% of the population are avoiding taking sodas due to some product error among other health concerns (Conv 2013). Due to persistent human errors, modern technology allows building of new working machines that allows for automatic correction of mistakes or alerts one in case there is an error (Badenhorst & Tonder 2004). This has greatly reduced human mistakes in their role in production companies and more so boosted quality final products with minimum faulty products reported.

On the other hand, machine errors are caused by several factors that directly affect the relevant machine performing a certain task. Component failure related to machine error occurs in a situation when different components play a role simultaneously hence colliding(Pop, A. 2012).This collision may cause the intended product to be faulty since the desired mechanism towards its production was not involved (Nguyen 2009). Mechanical failure is another kind of failure largely associated with machine errors. This entails breakdown of the system due to mostly unavoidable factors like wear and tear (Xu 2001). Machine errors can also arise due to improper or poor fixing during installation. This means that there is a likelihood of faulty products in the end of the production process.Poor fixing can be attributed to lack of detailed knowledge and complexity of the machines involved. Wrong choice of machines to perform a given task can also lead to faulty products in the wrong run. Organisations are advised to make the correct choice when it comes to selection of the machine for certain tasks (Stenberger& Chavez-Peon 2014).Moreover, it should be noted that some mistakes are caused by both human and machine error integrated together. Individuals can wrongly operate a spoilt machine consequently spoiling the process of production as well as the end product (Reisinger, J., &Kloger A. 2002).

Research findings

After a detailed research on the proportion of faulty Coca-Cola Company products, it was found that the faulty products accounts for as little as 0.0017% of the products in the market. Though the percentage is small, it should not be assumed since it can negatively affect the market share enjoyed by Coca-Cola. Notably, over 85% of this faulty products were as a result of human and machine error with logistics like transportation and storage accounting for the remaining 15%. Machine errors were as a result of wrong fixation and calibration. This means that some machines were not fixed in the required manner and also set in the described manner to automatically perform the required task with minimum human effort. Mechanical problems was also found to have an effect on the final products with faulty products being produced when there was witnessed mechanical breakdown or related aspects. This mostly was found to be as a result of wear and tear from the fixed machines mostly due to poor or no maintenance. There was a small percentage where machines were used for other tasks rather than the intended ones and hence this influenced the final product skewing the outcome to faulty products.

The human errors identified in this study were the wrong programming of the machines to execute required tasks. Improper administering of the ingredients was also reported to influence faulty products in the end though this was at a very low percentages. Directing or giving certain instructions to a wrong sector also contributed to faulty products in the market. This meant that some tasks or processes were carried out in the stages they were not meant to hence affecting the outcome of the product. Human error was also as a result of uncertified inventions of new products. The incorporations of new ideas meant to improve the quality of the products at times proofed otherwise causing faulty products to be produced instead.

Apart from human and machine error, the transportation and storage sectors also caused faulty products to reach the customers at the end. When products were stored in warm places, the quality was different from the cases when the products were stored in cool and dry places. Equally, frequent shaking of the products during transportation made some of them faulty and hence undesired by the customers.

Conclusion and recommendation

From the finding of the study, it is eminent that large proportion of faulty products is due to human and machine errors almost in equal measures. It should however be noted that the production of faulty products can be controlled by employing some factors in the operations of the company. To solve this mess, Coca-Cola Company should increase and improve the evaluation mechanisms of their machines involved in production. Proper sensitizing of the individuals on their roles should also be put into consideration to enable them deliver the best services expected of them. The company should also come up with a mechanism to verify the quality of their products before distributing them to consumers. In addition to this, retailers should be enlightened and advised on how to store the products to avoid selling unnecessary faulty products to consumers.
