the image is the cover for an article on 80/20 in consulting

The 80/20 Principle, also known as the Pareto Principle, states that 80% of results come from 20% of the effort. This principle, first identified by Italian economist Vilfredo Pareto, can be applied in a variety of ways to improve efficiency and increase productivity. In consulting firms, the 80/20 principle can be a valuable tool for optimizing operations and maximizing results.

This principle can be applied in many areas of business and has been particularly effective in the consulting industry. Firms such as McKinsey, BCG, and Bain have embraced the 80/20 principle and have used it to drive success and improve efficiency.

In this article, I explore the various ways in which the 80/20 principle can be applied in the consulting industry, including time management, client relationships, team management, and the case interview for applicants.

Time management

In the fast-paced and demanding world of consulting, efficient time management is critical. By applying the 80/20 principle, consultants can prioritize their efforts and focus on the most critical 20% of tasks that will deliver 80% of the results.

A typical consulting project lasts between 8 and 12 weeks, sometimes even less than that. Within that timeframe, you have no time to look into every potential lever to pull but should focus your efforts only on the most important analyses and initiatives that will move the needle for your client the most, otherwise, you are “boiling the ocean” as consultants call it.

The phrase “boiling the ocean” is often used in a business or analytical context to describe the tendency to attempt to solve too many problems at once or tackle an overwhelming amount of data and information. This approach often leads to a lack of focus and inefficiencies, as it is difficult to effectively analyze and make meaningful conclusions from such a large amount of information.

In essence, “boiling the ocean” refers to trying to tackle an enormous problem that is simply too big to solve in a practical and efficient manner or solving many smaller problems all at once. Instead of taking a systematic and focused approach, the tendency is to dive headfirst into the data, attempting to find the answers to every question and solve every problem. This can lead to an inability to identify the most important factors and a lack of meaningful conclusions.

In the world of top-tier consulting, it is crucial to take a more focused and strategic approach. By prioritizing the most important issues and focusing on the key factors that will have the greatest impact, consultants can make more informed decisions and avoid the pitfalls of “boiling the ocean”. This approach can lead to more effective and efficient results, allowing the analyst to effectively solve the most pressing problems and achieve the desired outcomes for their clients.

Client relationships

Strong client relationships are essential in the consulting industry. By applying the 80/20 principle, consulting firms such as BCG can prioritize their efforts and focus on the 20% of clients that will generate 80% of their business. This is also the reason why the top consulting firms only consult larger organizations that are able to afford their high fees and always aim for repeat projects with existing clients. It is always easier to build on an existing business relationship than to create a new one.

It is crucial for a firm’s growth to successfully apply this principle by identifying its most valuable clients and dedicating resources to cultivating these relationships. This allows consulting firms to deepen their relationships with their clients and deliver better and more impactful results.

Team management

Effective team management is also critical in the consulting industry. By applying the 80/20 principle, partners can focus on developing their top consulting staff and ensure that they have a strong pool of talent to draw from. All top-tier consulting firms such as Bain embrace this principle by focusing on developing their top talent and recognizing and rewarding employees who perform at a high level. This helps firms to maintain their most important asset, their employees.

The meritocratic approach to people management can also be seen in what is known as up-or-out.

Additionally, 80/20 also is used to divide and delegate tasks on a project. For instance, firms such as McKinsey encourage more junior consultants to focus on data analysis and number crunching while senior leadership focuses on the delivery of recommendations and client management. This allows firms to optimize their resources (and use them where they are most effective) and achieve better results.

Case interviews

The 80/20 principle can also be applied in case interviews for applicants. During a case interview, applicants are presented with a business problem and are expected to come up with a recommendation for the client. By focusing on the most critical 20% of the information and the problem, applicants can demonstrate their ability to work efficiently and effectively. For example, the top three firms are known for their rigorous case interview process, where candidates are expected to demonstrate their problem-solving skills and strategic thinking. By using the 80/20 principle, candidates can prioritize their efforts and develop a more effective solution.

Summing up

In conclusion, the 80/20 principle is a powerful tool that can be applied in many areas of the consulting industry. From time management to client relationships, team management, and case interviews, the 80/20 principle can help consultants and applicants work more efficiently, achieve better results, and drive success.

Firms like McKinsey, BCG, and Bain have embraced the 80/20 principle and have used it to achieve great success in the consulting industry. By understanding and applying this principle, individuals and firms in the consulting industry can improve their efficiency, productivity, and results.
