1. What is Business Improvement? The Benefits of Business Improvement

Before introducing the approaches and methods to achieve business improvement, this chapter will first explain what business improvement is. We will also introduce the objectives of business improvement and the benefits that can be obtained.
・What is business improvement in the first place?
Business improvement refers to the activities we undertake on a daily basis to improve our products, services, or processes.
For example, let's say we were producing 10 cars per day. By reviewing our work procedures, we were able to increase production to 11 cars. This is a simple example, but "reviewing work procedures" is considered business improvement.
By making changes to our daily tasks, we can increase productivity.
This is what we call business improvement.
・Purpose of Business Improvement
The purpose of business improvement is to improve productivity. In recent years, there has been a change in awareness towards labor, such as work style reform. As a result, there is a growing momentum for business improvement.
・Effects obtained from business improvement
There are three benefits that can be obtained through business improvement.
1. Improved Productivity
By improving our operations, we can create more and higher quality products and services. This can also lead to increased productivity, creating more time for new challenges that were previously impossible to tackle. These new challenges can further improve productivity and potentially create a positive cycle.
2. Cost Reduction
Improving productivity also leads to cost reduction. A familiar example would be overtime. If productivity increases and overtime decreases, it results in cost savings in terms of labor expenses. Reducing overtime by 2 hours a month would lead to a reduction of 48 hours a year. When multiplied by the number of employees, it becomes a significant figure.
3. Improvement of Working Environment
Business improvement brings significant benefits to workers as well. As mentioned earlier, by increasing productivity, it is possible to reduce overtime. An annual reduction of 48 hours of overtime equates to two full days. The time saved can be used for leisure or self-improvement, which leads to increased motivation.
2. How to Improve Business Processes

In the previous chapter, we introduced what business improvement is and the effects that can be obtained from it. In this chapter, we will introduce the specific steps for implementing business improvement, in three steps.
1. Set the target business
First, let's target the business processes we want to improve. We will conduct an inventory of operations, identify current issues and challenges, and find the business processes that need improvement. You should be able to identify tasks that have become formalized or inefficient. By writing them down on paper such as Excel, it will also be easier to reflect on them later.
There are likely issues and challenges present in varying degrees within each business process. For now, let's focus on identifying them in this phase.
2. Set Priority
Next, let's determine the priority target to work on based on the identified issues and challenges. While we would like to tackle everything, we have limited resources in terms of people and time, so let's prioritize and work on them.
There are two main criteria for prioritization.
The first one is the impact of improvement. We will prioritize based on the effectiveness of solving the issues.
The second one is the difficulty of improvement. Let's consider the total cost and effort, not just the time, for improvement.
We recommend using these two criteria to determine the priority order.
3. Creation of operation manuals, outsourcing, and introduction of tools
After selecting the target business for improvement, the next step is to determine the method for business improvement. There are various approaches to business improvement, such as creating a business manual, outsourcing, and introducing tools, which can be considered as typical examples.
The merits, demerits, and characteristics of each method will be introduced in the next chapter.
3. Does manual creation lead to business improvement?

So far, we have introduced what business improvement is and how to specifically implement it. In this chapter, we will explain whether manual creation leads to business improvement. There are various approaches to business improvement besides manual creation. We will compare and examine these other approaches.
1. Introduction of Systems and Tools
Routine tasks that occur repeatedly, such as daily work, are the strong suit of systems and tools. Therefore, there are means to introduce systems and tools for business improvement.
Considering efficiency, this can be said to be the most impactful means of business improvement.
On the other hand, the introduction incurs enormous costs. In addition to system development and implementation costs, time costs are also incurred for meetings with development vendors.
In recent years, contract forms that make it easier to introduce systems and tools, such as SaaS, have emerged.
Nevertheless, it is still a high hurdle for business improvement methods.
Additionally, it can be said that the operation after implementation is difficult. If the introduction to the field is not smooth, there is a risk that the system itself may not be used.
2. Outsourcing
Next is outsourcing. If the business processes that need improvement can be outsourced, let's make use of it. Especially when tasks that anyone can do are bottlenecks, it is recommended to actively utilize outsourcing.
As demonstrated by the Pareto principle, if you want to achieve better results, it is more efficient to focus on important initiatives.
However, there are mainly two disadvantages of outsourcing.
The first point is that know-how is not accumulated. Knowledge and experience that should be gained through work are lost when outsourced.
The second point is that there may be additional costs. The quality of the outsourcing partner will not meet the desired quality unless properly managed by the client. In cases of low quality, additional corrections may be required, which can lead to higher costs.
Outsourcing requires exploring the balance between outsourcing costs and quality.
3. Creating Operation Manuals
The final step is the creation of operational manuals. We will improve the highlighted issues and incorporate them into the operational manuals. By working together as a company, we can achieve uniformity in work quality and expect an increase in productivity. The more impactful the improvements, the greater the effect when the entire company collaborates.
For example, let's say that the differences in sales performance among individuals in the sales department have become a bottleneck for the company. In such cases, we will take measures to document the know-how of employees with good sales performance into manuals. By incorporating individual sales skills into the manuals, we can achieve uniformity in sales quality. This leads to the resolution of the bottleneck issue, resulting in a significant improvement for the company.

Each approach can certainly be considered an effective method for business improvement.
4. Summary
How was it?
This time, we introduced three approaches to achieve business improvement.
As an approach to business improvement, considering cost, difficulty of retention, accumulation of know-how, and cost-effectiveness, the most balanced option is the creation of business manuals. By establishing unified rules and procedures across the company through manuals, the quality of work stabilizes, and the training of new personnel progresses smoothly. Additionally, it prevents the personalization of tasks, allowing anyone to perform their duties with the same quality, thus the development of manuals ultimately leads to an increase in productivity.
Business improvement is not something that can be completed in one go; it requires continuous review. Therefore, it is important to create manuals that are used on-site and can be updated and operated with ingenuity. In today's world, where remote work and internal management via networks are prevalent, manuals that everyone can use play a crucial role.
That said, while many understand the necessity of manuals, there are likely many who find it difficult to actually create them. Creating them alongside regular duties can be particularly challenging.
In cases where "resources are lacking" or "there is no know-how in-house," outsourcing can be one solution.
